Thank you so much for this!! Perfect timing!! I'm a single female who knew absolutely nothing about roofing until now. I'm actually going to start the process of finding a company to do my roof hopefully in the spring. This gave me great tips (and I took notes) on what to ask, what to have in the contract and what to expect. So glad I found your channel....so helpful to this DIYer. Thanks and keep up the great work!!
I was JUST coming to leave a comment and say the same. As a single female I learned so a lot and feel much better before making calls. This is a great video!
We got our roof done this year, decided on metal because we got solar installed on it and wanted to make sure the roof would last as long as the solar panels. Love the sound during rain/hail! We are reaching net zero on our 1886 property! woth surprisingly low costs!
Yeah metal is nice but as a roofer myself I've seen the rubber washers on the screws that hold the metal on bake from the sun and that's 1000s of potential leaks
I agree about ice and water shield. It should go right on top of the plywood and not on top of the paper, old paper and the starter strips. The black stripe should be on the bottom not on top of the starter strip shingle your boy put it upside down I think he had no idea what he was doing.
I am looking for a recommendation for a decent roofing company in Mississauga area. There are so many these days it’s impossible to decide which one to go with.
Just had my 20 year old shingles replaced. Opted for all the bells and whistles - similar to your choices and it was still at a very reasonable cost. Of course my roof has a much more gentle slope and the work was completed in 2 days just in time for the winter.
I had metal vents written into my roofing contract. 5 years later I find out they did metal on the attic vents but plastic on the bathroom fans. They will skimp where ever they can get away with it so make sure you know enough to judge there work.
Just had this same system installed on my home yesterday. Ranch, so simpler project ... less money and 1 day install - looks great, good peace of mind. Nice video
I looked at my roof today while up getting caulking and touch up painting done. I need a new roof. This was most helpful. I think doing a roof in late Spring is likely best because the shingles will bond better if they get hot over the summer. I want to put in better roof ventilation as well. My roof exhaust fan quit working and the thing is not bird or squirrel proof anymore. I totally agree - do it all at one time. My biggest issue is do it all at one time vs. start from scratch. I keep noticing shoddy workmanship in my house that I've owned for 25 years already. The technology of newer building systems is so much better if built by a person with professional knowledge. I certainly lack the knowledge to hire the right contractor but I'm learning.
yes. Site protection is very very important. We just got a remodeled house with new roof and Roofing nails every where in the garden both old and new. I got a bucket full of them (about a gallon) and I still find them occasionally over a year later.
Not sure how different things are in Canada, but for the US I went with Certainteed after quite a bit of research. They have a very high quality shingle (I was looking for hail-resistant class 4), and if the installer has the correct certifications their warranty is NON pro-rated and includes labor and disposal.
I live in Québec city and this is the product that I choose last year. It is the same warranty that you described. What's more the warranty is good for 50 years, 50 years ! and I can transfer it to a new owner durening the first 12 years following the installation.

I just had an AS roof installed on my 1940s house (leaking and ceiling about to fall in!) I didnt see this video before I had it done, but after seeing this, I feel 900% more confident in my decision! $7800 for 18 square on an 8 pitch was not a bad price for what I got! Thank you for your fantastic videos! You're my go-to for my projects!
Like the guy in the video said....it has changed a lot over the last 20 years. I expect it will double in cost every 15 years moving forward as well. Cheers!
I've roofed for over 30 years and I do believe that your supposed to apply the ice and weather guard directly to the sheathing, plywood! Not over top of the old tar paper. Also, if your not taking the old tar paper off, how are you securing the old deck that will always come lose when tearing off the old shingles?
the irc requires removal of all roofing materials before installation of new materials. self adhered membranes can remain, and you are allowed to put the new materials over the old.
@@davec.3198 damn I feel sorry for the next roofers who have to try and tear those roofs off. Nothing that got my panties in a bunch like shingles welded to the ice guard!
Good video on shingle roofing technology. But pretty biased from an asphalt roof installer. If after 50 years your metal roof has a deteriorated coating, you can repaint it for a fraction of the cost than re-shingling the roof again. At least the house is waterproof and the panels haven't blown off. Exposed fastener metal roofing is very affordable compared to standing steam metal roofing. Asphalt shingles are not sustainable environmentally and frankly, financially.
You can’t just repaint a metal roof it has to be coated and coating a roof properly will cost more than installing a new metal roof. If it was the case that you could just paint a metal roof then no one would be doing metal roof tear offs
@38snipshow 100% agreed. I despise the 'cheapest is best' or 'I'm going to flip it in a couple of years so why spend the money' mentality. That 'thinking' creates a vicious cycle of mediocrity.
The problem is that quality isn't something buyers pay for when house shopping. They pay for interior renovations, square footage, and schools. A new 50 year roof isn't going to get you a significantly higher sale price vs a 20 year old shingle roof. Same with insulation, air sealing, quality siding, etc.
Thanks for this great informative video. I am in the process of getting quotes for a new roof. I was curious about a metal roof because it seems to be the new thing. I had no idea about roofing. Now I know what to ask. I took lots and lots of notes. Now I feel more knowledgeable. Thank you.
Jeff mentions upkeep costs. So true. There are some good looking houses in my neighborhood that would be really hard to roof. Lots of valleys, strange angles and high pitches. The last estimate for our simple 1600sf ranch with a 8/12 pitch was $5700 (Alabama). Back when we bought our house I insisted on a smaller, simpler house with a basement and a brick finish to my wife's annoyance. She's finally coming around as we have gotten older.
simple houses are much more efficient in both maintenance and energy cost and lower cost to build. Everything else is designed to impress only! The more folks care about being practical the lower the values of those impressive costly homes will be!
Woke up to shingles blown off the roof this morning (Georgia), not too bad of a storm yesterday, so curious about the condition of the deck. Great video timing! This helps at least understand the terminology for when we get someone out to inspect the roof and get estimates to repair/replace. Its a 10yo roof, but looks in great condition. Bought the house 1.5years ago and roof inspection came back really solid. Was hoping to get at least 2-5 years out of the roof, but I guess we'll see whether replacing or repairing is best.
My UK house has a slate roof, the tiles are very heavy. It appears to be a long lasting material but a expensive option in terms of the tiles + installation.
Jeff, your honesty and professionalism explaining things on how to do it right are practically killing others dishonest contractors and dropping like a flies in the river..... keep up the good work Raymond
These “honest” contractors didn’t remove down to the decking. Went right over the existing tar paper. On a roof in that bad condition there’s a very good chance there’s bad decking and it won’t be getting replaced due to them never inspecting it. Instead of making this video he should’ve spent more time on learning a little bit about roofing. Majority of the time you get what you pay for though.
Jeff, I am so glad you focused on the ugly realities of the shingle warranty. When is 50 years not really 50 years etc? In regard to metal shingle roofs, the installation labour component is 3-4 times as high. Each metal shingle is screwed in with 6 screws which takes much more time when compared to a nail gun installing an asphalt shingle. Contractors simply don't make as much MONEY with steel shingles. They cannot do the whole job in one quick 'payday' so they discourage a customer who really wants a long lasting product. Lastly, why is snow sliding off a metal roof a problem? Nobody with a metal roof worries about the weight of snow building up on their roof after a heavy snowstorm or a series of snowfalls. If the grading and drainage around your foundation is wrong, it is wrong regardless of what type of roof you have. Finally, when we drive around in the country we see lots of steel roofs which are far, far older than 50 years. You will never see an asphalt shingle roof attaining an age anywhere close to that.
the question is not which is better. it is which is better in each situation. a good metal roof install is still the Cadillac but financially it is not even a consideration for many people. so understanding the industry will help to manage expectations.
@@HomeRenoVisionDIY Thanks for the reply Jeff, I think this video offered real insight to several important considerations people might make in evaluating their roofing options. In regard to steep roofs, I recently re-roofed my shed and it is amazing how much steeper it is today compared to when a younger me built it 17 years ago ;-)
Good points regarding the metal roofs. I've been considering doing a metal roof on my attached garage and asphalt on the main house. Could be bad news for my car parked in the driveway.
Did you consider cutting in soffit ventilation? I am looking at an old farmhouse 12x12 pitch and plan on adding ventilation. Will rip open interior sloped ceiling to add in ventilation baffles and insulation then re-drywall...
Love your show! I brought a side by side duplex 9 yrs ago. Today I had the roof looked at to get info of what kind of shape its in. Two different companies said its in good shape. But I can get Armorflex Roof Resin applied to protect the roof and get a 15 to 20 yrs warranty with it. My property is 2400 sqft and the cost of the resin to be applied is around 5k. A new roof will be 10 to 15k. What are your thoughts on resin applied to a roof to protect it? Is it worth the money? My roof has a lower pitch than your house.
Thank you, thank you & thank you. I was hoping you would do a roof video and here it is. I have to replace shingles this coming spring and all the information I can get, the better. I learned a lot from the video and will re-watch and take notes so I will have them at hand when I interview & get quotes when the time comes. I really appreciate all the videos you do, you explain things so it makes sense and we can save money & time. Thank you again.
i live in belgium, so we have baked clay tiles as roofing, and our roof has been on our house for 60 years now. still works great, and no leaks either.
Clay tile roofs last a long, long time in a mild climate like yours but they cost a fortune to install. In Canada with our severe climate, the best option for a long lasting roof is a steel roof.
@@rightlanehog3151 yes i could see that, in your location that would be favorable to install. and for our roof we paid around 25 thousand euro`s for a new roof.
@@rightlanehog3151 They're popular up in the Nordic countries too, where we have a similar weather to most of Canada. The problem with a steel roof is that they're reaaaaally noisy when it rains. Ceramic tiles are heavy, so they're very quiet even during heavy rain.
@@VortechBand I only spent a week in my visit to the 'Nordic' countries and what I remember most is that Norwegian wooden houses were actually made of wood not plastic . If your steel roof is too noisy your roof sheathing is too thin. I sleep like a contented log under mine but I do have 1 inch of plywood beneath the shingles. In a really bad storm I just snore louder to cover the sound of the raindrops.
Cool video! BUT they didnt remove the felt paper! This is an old home, so it might even have 2 to 3 layers of paper. The Ice and Water needs to stick to the plywood and not the felt paper! Minute 3:46.
i have an 8/12 roof and that is too steep for me to diy. i think that i could have handled a 4/12 pitch, but 8/12 was too much. i would be spending so much time worrying about my steadiness on the roof and trying to deal with occasional disorientation due to the roof pitch, that it would be a major distraction from the task at hand. as this video says, sometimes it is best to know your limits.
At 4:33, you say that the last layer, the finish layer, is the shingles, step 4. Then at 4:57, you say that step 5 for any roof is the synthetic membrane. So I'm confused already. :(
After a disasterous experience with letting some rookie replace my roof....will never make that mistakes again! Always hire a professional! Ended up having to have the entire roof removed and redone! Let the pro's handle it. Now, Jeff...what is the color paint you used in your house where you are standing? I love it and have been looking for that perfect bluish color!
I was supposed to close on my house on Tuesday, but the FHA said there were nail pops all over the roof. So the seller is replacing the whole damn thing. So now I close on the 6th, with a brand new roof😁😁😁😁😁😁😆. Can't freaking wait
Did my own tile roof 20ys ago, but paid for tile loading and a crew 1k to do continuous hotmop on a 43lb paper with 105 lb premium then tile, shd last 60+ yrs. Today they put garbage 1 layer 50lb junk under tile. This 25k roof cost me 4k in materials in 2000. Doing it yourself or a portion can really save and you can put much better materials, example a peel and stick self sealing under this shingle with a genie lift might be doable and still cheaper in the end?
Right there with you on not doing roofing anymore. I've done my share of roofs over the years, including my own. But those days are long gone. It's hot, it's hard, and it's dangerous. I have no interest in lugging shingles up a ladder, or climbing around on a roof ever again.
Didn't see it asked, but if they were stripping of the old roof, why didn't they do it all? I noticed at the 3:10 spot as they started installing he membrane, that they were installing it over old shingles. I've always been told you can cover an initial layer, but they took the time to strip off the top layer, why not give you that extra protection by getting "all" of the old stuff off.
Just looks that way. Its a very old house with board planks instead of plywood. Youre seeing the gaps between the boards. They're stained black from 100 years of various tar paper.
Great video! It will be really helpful when getting bids. My issue is that I know we will need to replace our soffits, fascia, and roof. And I don’t know where to start. Roofing contractor? Do they do that? I guess I just have to start there.
Again great informative video!!! Wished I would have had this information 2 months ago. Probably would have saved me some money. Went with standing seam on same pitch roof on forever house.
I love how the salesperson told you they needed to inspect the wood but in the video, they just left the previous felt on and put synthetic over it..... a good way to suffocate the wood.
Jeff. 1955 house with false soffets (no airflow) so adding vents does nothing at this point. The roof is a hip type with a gable inside the garage (where they adjusted the attic access after adding furnace venting). Would you recommend adding a couple of power roof vents to maintain some sort of air flow, regular roof vents or something else? I just thought about it with this video so would need to see exactly what venting I currently have.
Just adding vents at the ridges won’t promote good attic ventilation. If you add vents close to the eaves as intake AND at the ridges as exhaust then you will be in good shape
Some drunk will probably be willing to do it for less than that in squirrelville, Kentucky where you’re from. And then you can call the real pros with the big boy price a year later when the whole thing is leaking
Your Roofers are hacks. They should use Scaffolding, Do do more damage Wearing ropes walking on the shingles. All the twisting and turning. With scaffolding they could throw the shingles directly in the trailer. Professional roofers use their own trailers not dumpster. Look at how much extra work that is because of where the dumpsters at. It would take me hours To tell you all the mistakes. You’re just excited you’re hired cheapest roofers. Like the guy said it’s imperative to strip your whole roof inspector the deck? However they just installed the icewater Shield Over top of the tar paper. You should always install synthetic overtop the ice water shield. Is the ice water shield melts to the Shingles.
The roofers did not inspect the wood deck like their boss was just preaching. That's what worries me about hiring out work, the sales guy /manager can promise everything, but at the end of the day the lower level guys determine the quality you'll actually get.
Thanks for sharing, your videos are very helpful! I'm wondering how did you ventilate your mansard roof? I live in Northern qc, my house looks a lot like yours. I need to address my ice dams issues, I'm thinking about doing it from the inside. But I recently saw that I could insulate over the existing roof sheating..what method would you prefer?
WOW Jeff, I usually enjoy your videos on home reno projects, but I have to say this one was way, too inaccurate!! After 35 years in the roof industry, as an inspector, specification writer, and director of sales and marketing for a Toronto area roof contractor, I have to say this video was bery misleading. You start out saying it is a GAF system, then use the name CertainTeed, while all the while, one could see the contractor was installing BPCO products. There was no sign of eave or gable/rake drip edge, the foundation of a roof system. Then, they were placing Ice & Watershield, without peeling the backing off, on top of old underlay (tarpaper). You talked to the contractor about getting down to the wood deck to inspect it, but there was no wood exposed. The synthetic underlay was also applied on top of the old tarpaper. What gives?? I know that if a GAF or CertainTeed system is installed by one of their certified contractors, then the warranty is registered by them, AND the warranty is non pro-rated for 50 years, and can be transferred to one new homeowner in the first 20 years. Yes, just as good as a metal roof!! (Both materials have their place in the industry. I have installed both.) I usually like your enthusiasm, but this time, you spoke over and interrupted the guy from Roofmaster, over and over. This video needs to be removed - or done over properly - before people get the wrong impression. C'mon Man, YOU CAN DO BETTER than this JEFF. Very frustrated and disappointed, Dave
I agree.. Worst video he has done. Very misleading. Very bad information and people that don't know will think it's great.. And this crew should be fired for installing almost everything wrong.
I gotta say yeah, I caught almost all of those things too. I thought they were installing the Ice and water over something pretty ugly.But, It could've been some old ice and water, which I'm okay with.
Hi Jeff, do you have recommendation on remove moss from roof and moss prevention after cleaning? I live in the soggy PNW :-( Do you recommend kill moss with bleach, or Zinc powder? Is this a job that I should hire people to do or utilize my teenager boys. We have a single level house so the roof is not high or steep. Thanks
Hi Jeff. I have a question about mold in my attic. About a quarter of the attic has black spots. My question if I can eradicate the mold myself with cleaning solutions, painting with mold killing primer etc. or is this one of those things that I should leave to the professionals? Any thoughts would be very helpful because we are getting quoted at 2k to clean the mold
Absolutely first thing to do is find the CAUSE of the mold, or you will have a never-ending battle with it. Also, remember some of it will be hidden in areas you can''t see or easily find, causing continuing damage. BTW, I've always use ozone treatment as part my mold remediation strategy, but if you do be careful of the health affects.
mold is usually caused by condensation and lack of ventilation. especially in high humidity environments. The solution is to reduce condensation and increase ventilation. Temporary band aides won't work. don't waste your time.
Question....if I'm putting up a 3 inch crown molding up on my just newly sheetrocked wall. Do I need to technically mud the joint were the wall meets the ceiling????? I only ask because I'm a firm candidate in doing things the right way. I'm also putting up a two inch wide chair railing. I purposely put all my "butt joints centered in the wall were we are installing the chair railing. I also need to know if considering my chair railing is going to be completely covering the butt joint is there any need in mudding the butt joint? I already pre filled the joint so it will be sealed. Is there a down side to not finish mudding the butt joint considering the chair rail will cover it as well???? Thanks ! I also want to give you a huge thank you for all your videos as we have learned so much and our Diy remodeling has gone better than we ever thought it would!!
Update: lol! I watched your master class drywall video "again" and it answered my questions! Sorry, I should have been more diligence. Lol! I drywalled a house i owned about 15 years ago and I was not happy at all at the results then. But this time I doing as close to how you teach as possible and I am just amazed at how good its coming along! I had a buddy come over and when he saw the results he accused me of hiring a pro to make myself look better! Lol! I can't thank you enough for your videos. Your an excellent teacher! P. S. My wife says when we are done dumping obscene amounts of money into our remodeling, she wants to send you a gift 🎁 😉 for all your help. You have literally saved us thousands of dollars 💵 !
I am confused with the sequence in video. You first show ice and water shield and then shingles. Then it suddenly goes to the synthetic underlayment making it look like you are putting that on top of Shingles !! So now I am not sure if the sequence is ice and water shield underlayment 3 feet from eaves and then synthetic underlayment over entire roof and then shingles ?
They are extremely expensive here in Canada and very rare. We also have a much more severe climate than the UK so I am unsure whether clay tiles would hold up in the freeze thaw cycle over the years.
@Mr. Canadian dumbass Slate is a rock mined from the ground, clay tiles are baked like bricks. I see a lot of Canadian bricks failing after 30 years so I am unsure we would be up to the task of making durable roof tiles.
Hi Jeff. I don't know how to contact you otherwise so I'm just commenting here. I own a Condo in Toronto, one of those old pour concrete big apartment-style condos. All the walls are 2 inches poured concrete. Can you do a video on dealing with concrete walls and what I should do to properly renovate when I don't have studs. Thank you.
6:20 There's not a company on planet earth that will do as good or a better 'system' for $12,000 than the company who charges $20,000 for the same 'system.' So that's just not true. You must live in a really cheap roofing area if the range for a good, complete job, including new wood, is $7,000 to $12,000 depending on the pitch of the roof.
Great info here. I wish I knew exactly how old our roof was, neighbors say it was probably replaced when they all got new roofs after some hail, which was 2013 or so. When selling, it just said less than 9 years old. I have architectural shingles as well. However, our attic up until last month had poor insulation and air circulation so I finally had that fixed up for ice dams. I'm guessing the multiple years of damming have dropped some of that life expectancy (thanks previous owners 🙄). I also am not sure whether they got it done right, judging from everything else I wouldn't be surprised if they got the cheapest bid so I have no idea how they built it and whether there's proper components for water diversion. So far visually inspecting the roof, it looks like it's doing okay, I've been up there a few times. Discovered some nutty things though like a vent going up and it wasn't aligned with the cap so there was gaps where rain could easily just go straight down into the attic 🤬 Replaced the cap on it to mitigate that but jeez.
Sounds like you are keeping yourself very busy. I’m in the market for my first home purchase and my favorite house looks like it needs a new roof. Good luck to you!
I really appreciate all the instructional videos you are doing but I strongly suggest you make a supplemental video to this one as critical factors such as drip and rake edges were neither installed nor discussed and no comments either about step or kick out flashing. You are so good in discussing code changes and innovations but a few key points were missed here. Without proper flashing the roofers are going to use a lot of caulking to try to seal roof/wall joints which will never last as you know. These items have to be discussed upfront and can explain pricing differences between some quotes as well.
Amazing! Then there's me on my knees clawing my way up a 6/12. One of the few times I'll admit I look like a sissy. I had a chance to make amazing money being a roof estimator and I literally couldn't even talk myself into getting up on the sketchy roofs to give a quick analyze.
Hey Jeff what is that red sq drive bit you always use? Where can I get that thing at? Cause as much as you use it that thing looks like it never wears out haha I need one!
3 days?! If my crew took 3 days to do a house this small they would be kicking rocks. You have to take off all the felt to inspect the decking. You never want to lay ice and water over tar paper and you need to take the backing off. There needs to be more than 4 750 vents on a roof that size. You need proper ventilation.
My roofer cousin and I put the 3d " architectural" shingle on my double wide 2yrs ago. I chose to put the "ice and water" over the whole roof. I figured better safe than sorry since I live in the cone of uncertainty in NWFL. It still looks great and has no leaks after Sally.
Do not buy a flat roof! I've work on several jobs involving leaks in a flat roof and they are a pain in the ass. Biggest problem is the difficulty in locating a leak, that water can travel the whole roof system (after finding a penetration point) until it finds a weak point which could be many yards/meters away and now you have an entire roof to tear out.
I don't quite understand why the old tar paper didn't get removed considering they used a better synthetic underlayment anyways but I'm not a pro roofer so must be a reason...? Regardless, I'm in the process of re-doing my 9/12 pitched roof and with 3 layers of asphalt there is absolutely zero chance I could save the old tar paper.
Thank you so much for this!! Perfect timing!! I'm a single female who knew absolutely nothing about roofing until now.

@briscoesjug1026 would a standing seam roof work better in that regard?
I agree about ice and water shield. It should go right on top of the plywood and not on top of the paper, old paper and the starter strips. The black stripe should be on the bottom not on top of the starter strip shingle your boy put it upside down I think he had no idea what he was doing.
Need a new roof and this helps give me an understanding and knowledge to make decisions and not be screw or taken advantage of. Thank you Jeff!

Correct. I used gracie snow and ice right up to the ridge vent. Roof will not leak for a VERY long time. Cheap insurance.
Correct ice and water goes only on sheathing..if its put over paper it is pointless it leaves a gap in between and doesnt stick

If after 50 years your metal roof has a deteriorated coating, you can repaint it for a fraction of the cost than re-shingling the roof again. At least the house is waterproof and the panels haven't blown off. Exposed fastener metal roofing is very affordable compared to standing steam metal roofing. Asphalt shingles are not sustainable environmentally and frankly, financially.
You can’t just repaint a metal roof it has to be coated and coating a roof properly will cost more than installing a new metal roof. If it was the case that you could just paint a metal roof then no one would be doing metal roof tear offs
@38snipshow 100% agreed. I despise the 'cheapest is best' or 'I'm going to flip it in a couple of years so why spend the money' mentality. That 'thinking' creates a vicious cycle of mediocrity.
I agree I just put a standing seam metal roof on my house. It was a lot of work but worth it.

The problem is that quality isn't something buyers pay for when house shopping. They pay for interior renovations, square footage, and schools. A new 50 year roof isn't going to get you a significantly higher sale price vs a 20 year old shingle roof. Same with insulation, air sealing, quality siding, etc.
@@danbert8 That is the sad reality, in our warped market finishes are also more important than structure. The solution is a better building code.
Had the roof replaced when we bought the house part of the agreement. Always good information thank you.
I'm in ct been roofing for 20 years now we use 6 ft ice and water then synthetic paper..6 nails per shingle
Thanks for this great informative video. I am in the process of getting quotes for a new roof. I was curious about a metal roof because it seems to be the new thing. I had no idea about roofing. Now I know what to ask. I took lots and lots of notes. Now I feel more knowledgeable. Thank you.
Jeff mentions upkeep costs. So true. There are some good looking houses in my neighborhood that would be really hard to roof. Lots of valleys, strange angles and high pitches. The last estimate for our simple 1600sf ranch with a 8/12 pitch was $5700 (Alabama). Back when we bought our house I insisted on a smaller, simpler house with a basement and a brick finish to my wife's annoyance. She's finally coming around as we have gotten older.
simple houses are much more efficient in both maintenance and energy cost and lower cost to build. Everything else is designed to impress only! The more folks care about being practical the lower the values of those impressive costly homes will be!
Woke up to shingles blown off the roof this morning (Georgia), not too bad of a storm yesterday, so curious about the condition of the deck. Great video timing! This helps at least understand the terminology for when we get someone out to inspect the roof and get estimates to repair/replace. Its a 10yo roof, but looks in great condition. Bought the house 1.5years ago and roof inspection came back really solid. Was hoping to get at least 2-5 years out of the roof, but I guess we'll see whether replacing or repairing is best.
My UK house has a slate roof, the tiles are very heavy. It appears to be a long lasting material but a expensive option in terms of the tiles + installation.
they last hundreds of years. nice when you don't have any ice damning. we could never use that!
@Mr. Canadian dumbass - Yeah. I've seen lots of slate roofs here in NE Ohio as well.
But only on really pitched roofs. 12 x 12 and steeper.
We use almost the same technology in Croatia. Great stuff.
Very cool! Cheers!
Jeff, your honesty and professionalism explaining things on how to do it right are practically killing others dishonest contractors and dropping like a flies in the river..... keep up the good work
Raymond
These “honest” contractors didn’t remove down to the decking. Went right over the existing tar paper. On a roof in that bad condition there’s a very good chance there’s bad decking and it won’t be getting replaced due to them never inspecting it. Instead of making this video he should’ve spent more time on learning a little bit about roofing. Majority of the time you get what you pay for though.
Jeff, I am so glad you focused on the ugly realities of the shingle warranty. When is 50 years not really 50 years etc? In regard to metal shingle roofs, the installation labour component is 3-4 times as high. Each metal shingle is screwed in with 6 screws which takes much more time when compared to a nail gun installing an asphalt shingle. Contractors simply don't make as much MONEY with steel shingles. They cannot do the whole job in one quick 'payday' so they discourage a customer who really wants a long lasting product. Lastly, why is snow sliding off a metal roof a problem? Nobody with a metal roof worries about the weight of snow building up on their roof after a heavy snowstorm or a series of snowfalls. If the grading and drainage around your foundation is wrong, it is wrong regardless of what type of roof you have. Finally, when we drive around in the country we see lots of steel roofs which are far, far older than 50 years. You will never see an asphalt shingle roof attaining an age anywhere close to that.
the question is not which is better. it is which is better in each situation. a good metal roof install is still the Cadillac but financially it is not even a consideration for many people. so understanding the industry will help to manage expectations.
@@HomeRenoVisionDIY Thanks for the reply Jeff, I think this video offered real insight to several important considerations people might make in evaluating their roofing options. In regard to steep roofs, I recently re-roofed my shed and it is amazing how much steeper it is today compared to when a younger me built it 17 years ago ;-)
How about hail damage
Good points regarding the metal roofs. I've been considering doing a metal roof on my attached garage and asphalt on the main house. Could be bad news for my car parked in the driveway.
Did you consider cutting in soffit ventilation? I am looking at an old farmhouse 12x12 pitch and plan on adding ventilation. Will rip open interior sloped ceiling to add in ventilation baffles and insulation then re-drywall...
Love your show! I brought a side by side duplex 9 yrs ago. Today I had the roof looked at to get info of what kind of shape its in. Two different companies said its in good shape. But I can get Armorflex Roof Resin applied to protect the roof and get a 15 to 20 yrs warranty with it. My property is 2400 sqft and the cost of the resin to be applied is around 5k. A new roof will be 10 to 15k. What are your thoughts on resin applied to a roof to protect it? Is it worth the money? My roof has a lower pitch than your house.
You make the best videos in DIY and renovations. Hands down.
Thank you, thank you & thank you. I was hoping you would do a roof video and here it is. I have to replace shingles this coming spring and all the information I can get, the better. I learned a lot from the video and will re-watch and take notes so I will have them at hand when I interview & get quotes when the time comes. I really appreciate all the videos you do, you explain things so it makes sense and we can save money & time. Thank you again.
i live in belgium, so we have baked clay tiles as roofing, and our roof has been on our house for 60 years now. still works great, and no leaks either.
Clay tile roofs last a long, long time in a mild climate like yours but they cost a fortune to install. In Canada with our severe climate, the best option for a long lasting roof is a steel roof.
@@rightlanehog3151 yes i could see that, in your location that would be favorable to install. and for our roof we paid around 25 thousand euro`s for a new roof.
@@justinvanmierlo302 I would have thought it might cost more than that. In any case, you are set for the next 100 years.
@@rightlanehog3151 They're popular up in the Nordic countries too, where we have a similar weather to most of Canada. The problem with a steel roof is that they're reaaaaally noisy when it rains. Ceramic tiles are heavy, so they're very quiet even during heavy rain.
@@VortechBand I only spent a week in my visit to the 'Nordic' countries and what I remember most is that Norwegian wooden houses were actually made of wood not plastic . If your steel roof is too noisy your roof sheathing is too thin. I sleep like a contented log under mine but I do have 1 inch of plywood beneath the shingles. In a really bad storm I just snore louder to cover the sound of the raindrops.
If they are doing GAF warranty you have to remove the old underlayment too lol.
Good Advice , TY and give a big shout out to the guy that took the time to explain .

Thanks so much, would love to hear your opinion if you were to live in the house. Longevity/ the right way is always the best althought more costly
Wow Jeff, looking at your old roof, you really needed a new one!! The new roof turned out great!! This video is informative. Thank you!!
Cool video! BUT they didnt remove the felt paper! This is an old home, so it might even have 2 to 3 layers of paper. The Ice and Water needs to stick to the plywood and not the felt paper! Minute 3:46.
i have an 8/12 roof and that is too steep for me to diy. i think that i could have handled a 4/12 pitch, but 8/12 was too much. i would be spending so much time worrying about my steadiness on the roof and trying to deal with occasional disorientation due to the roof pitch, that it would be a major distraction from the task at hand. as this video says, sometimes it is best to know your limits.
Also if gettin roof done do it ASAP. Price has gone up 4 times since January. And is expected to go up to be 50 percent more then last year same time
At 4:33, you say that the last layer, the finish layer, is the shingles, step 4. Then at 4:57, you say that step 5 for any roof is the synthetic membrane. So I'm confused already. :(
After a disasterous experience with letting some rookie replace my roof....will never make that mistakes again! Always hire a professional! Ended up having to have the entire roof removed and redone! Let the pro's handle it. Now, Jeff...what is the color paint you used in your house where you are standing? I love it and have been looking for that perfect bluish color!
Excellent information. There's a lot of variables to take into account when buying a roof. I never knew.
I was supposed to close on my house on Tuesday, but the FHA said there were nail pops all over the roof. So the seller is replacing the whole damn thing. So now I close on the 6th, with a brand new roof😁😁😁😁😁😁😆. Can't freaking wait
congratulations. Cheers!
Thank you so much!!! This is the one part of the home I was always up on but knew the least about.
Did my own tile roof 20ys ago, but paid for tile loading and a crew 1k to do continuous hotmop on a 43lb paper with 105 lb premium then tile, shd last 60+ yrs. Today they put garbage 1 layer 50lb junk under tile. This 25k roof cost me 4k in materials in 2000. Doing it yourself or a portion can really save and you can put much better materials, example a peel and stick self sealing under this shingle with a genie lift might be doable and still cheaper in the end?
those prices he just said are "outrageous" !!! are they taking advantage of people or what??? 😮😮😮😱😱😱
Right there with you on not doing roofing anymore.
I've done my share of roofs over the years, including my own. But those days are long gone.
It's hot, it's hard, and it's dangerous.
I have no interest in lugging shingles up a ladder, or climbing around on a roof ever again.
Did mine last year and forgot how back breaking it was. My buddy and I could hardly get in the truck each day. Oh and it turned into a blizzard lol.
I did roofing one hot summer day. I never went back.
5'4, 130 pounds, did it for 8 years-- It's not for the weak.
Didn't see it asked, but if they were stripping of the old roof, why didn't they do it all? I noticed at the 3:10 spot as they started installing he membrane, that they were installing it over old shingles. I've always been told you can cover an initial layer, but they took the time to strip off the top layer, why not give you that extra protection by getting "all" of the old stuff off.
Just looks that way. Its a very old house with board planks instead of plywood. Youre seeing the gaps between the boards. They're stained black from 100 years of various tar paper.
Great video! It will be really helpful when getting bids. My issue is that I know we will need to replace our soffits, fascia, and roof. And I don’t know where to start. Roofing contractor? Do they do that? I guess I just have to start there.
Again great informative video!!!
Wished I would have had this information 2 months ago. Probably would have saved me some money. Went with standing seam on same pitch roof on forever house.
Thanks for all your help! So much knowledge on so many topics, peek up the great work! Cheers from NB!
What about the peal celifane over the tar drops does the celifane need to be removed first before layering continue up the roof...
I love how the salesperson told you they needed to inspect the wood but in the video, they just left the previous felt on and put synthetic over it..... a good way to suffocate the wood.
Jeff. 1955 house with false soffets (no airflow) so adding vents does nothing at this point. The roof is a hip type with a gable inside the garage (where they adjusted the attic access after adding furnace venting). Would you recommend adding a couple of power roof vents to maintain some sort of air flow, regular roof vents or something else? I just thought about it with this video so would need to see exactly what venting I currently have.
Just adding vents at the ridges won’t promote good attic ventilation. If you add vents close to the eaves as intake AND at the ridges as exhaust then you will be in good shape
$12,000-$20,000 are these people out of their mind😮😮😮😱😱😱
It’s also overbidding because they don’t want to do it. I’m a landscaper and will throw out a high number when I really don’t want to take the job on.
Some drunk will probably be willing to do it for less than that in squirrelville, Kentucky where you’re from. And then you can call the real pros with the big boy price a year later when the whole thing is leaking
@@michaelyoder7329 Michael "Yodler"🙄🙄🙄
any tips for replacing the flashing on a roof?
Your Roofers are hacks. They should use Scaffolding, Do do more damage Wearing ropes walking on the shingles. All the twisting and turning. With scaffolding they could throw the shingles directly in the trailer.
Professional roofers use their own trailers not dumpster. Look at how much extra work that is because of where the dumpsters at.
It would take me hours To tell you all the mistakes. You’re just excited you’re hired cheapest roofers. Like the guy said it’s imperative to strip your whole roof inspector the deck? However they just installed the icewater Shield Over top of the tar paper.
You should always install synthetic overtop the ice water shield. Is the ice water shield melts to the Shingles.
The roofers did not inspect the wood deck like their boss was just preaching. That's what worries me about hiring out work, the sales guy /manager can promise everything, but at the end of the day the lower level guys determine the quality you'll actually get.
Now I know why my plywood all around the edges of my roof had rot when I re-shingled. No ice and water shield was installed there.
You really dont need ice and water on your edges but most definitely want drip edge on your rakes..f5 on edges and f8 on bottom
Thanks for sharing, your videos are very helpful! I'm wondering how did you ventilate your mansard roof? I live in Northern qc, my house looks a lot like yours. I need to address my ice dams issues, I'm thinking about doing it from the inside. But I recently saw that I could insulate over the existing roof sheating..what method would you prefer?
Any advice on gutters? Thanks!
Always great videos, tips and things to consider to projects.
WOW Jeff, I usually enjoy your videos on home reno projects, but I have to say this one was way, too inaccurate!! After 35 years in the roof industry, as an inspector, specification writer, and director of sales and marketing for a Toronto area roof contractor, I have to say this video was bery misleading. You start out saying it is a GAF system, then use the name CertainTeed, while all the while, one could see the contractor was installing BPCO products.
There was no sign of eave or gable/rake drip edge, the foundation of a roof system. Then, they were placing Ice & Watershield, without peeling the backing off, on top of old underlay (tarpaper). You talked to the contractor about getting down to the wood deck to inspect it, but there was no wood exposed. The synthetic underlay was also applied on top of the old tarpaper. What gives??
I know that if a GAF or CertainTeed system is installed by one of their certified contractors, then the warranty is registered by them, AND the warranty is non pro-rated for 50 years, and can be transferred to one new homeowner in the first 20 years. Yes, just as good as a metal roof!! (Both materials have their place in the industry. I have installed both.)
I usually like your enthusiasm, but this time, you spoke over and interrupted the guy from Roofmaster, over and over. This video needs to be removed - or done over properly - before people get the wrong impression.
C'mon Man, YOU CAN DO BETTER than this JEFF.
Very frustrated and disappointed,
Dave
I agree.. Worst video he has done. Very misleading. Very bad information and people that don't know will think it's great.. And this crew should be fired for installing almost everything wrong.
I gotta say yeah, I caught almost all of those things too. I thought they were installing the Ice and water over something pretty ugly.But, It could've been some old ice and water, which I'm okay with.
Kind of hard to see in the video, but it looks like the starter was installed backwards as well. You want that sealant strip close to the edge
I have a 12/12 pitch. Had to pull off 4 layers of shingles and remove the old slats and install sheathing. I HATE 12/12 pitch
the only good thing about that pitch is the living space on the top floor is great!
"Sometimes DIY is knowing when to make a phone call" lol - yep
I can’t wait Jeff, it’s like you know what jobs I’m up to and then you film a video. Thank you in advance from Australia 🇦🇺
So much great advice!
Good info and I know the guys too ! They are always around the area👍
Buying a house and the skylights need to be replaced. Gonna do the roof as well👌
Hi why are you talking About GAF system if you are installing BP shingles?
I went with BP and metal valleys
Hi Jeff, do you have recommendation on remove moss from roof and moss prevention after cleaning? I live in the soggy PNW :-( Do you recommend kill moss with bleach, or Zinc powder? Is this a job that I should hire people to do or utilize my teenager boys. We have a single level house so the roof is not high or steep. Thanks
Hi Jeff. I have a question about mold in my attic. About a quarter of the attic has black spots. My question if I can eradicate the mold myself with cleaning solutions, painting with mold killing primer etc. or is this one of those things that I should leave to the professionals? Any thoughts would be very helpful because we are getting quoted at 2k to clean the mold
Absolutely first thing to do is find the CAUSE of the mold, or you will have a never-ending battle with it. Also, remember some of it will be hidden in areas you can''t see or easily find, causing continuing damage. BTW, I've always use ozone treatment as part my mold remediation strategy, but if you do be careful of the health affects.
mold is usually caused by condensation and lack of ventilation. especially in high humidity environments. The solution is to reduce condensation and increase ventilation. Temporary band aides won't work. don't waste your time.
Make sure that none of your bathroom/kitchen vents exhaust into the attic. They MUST vent to the outside.
It is good information. Do you know is it good to have more static vents or using a turbine vent for the roof? Is there any building code for that?
Jeff you'd be so jealous too see how long those types of roofs last in the California Valley. A "25 year roof" will last 30+.
Maybe. But a "25 year roof" in Texas will last 12-15 years. The first big hail storm will cause too much damage, at least here in central Texas.
Question....if I'm putting up a 3 inch crown molding up on my just newly sheetrocked wall. Do I need to technically mud the joint were the wall meets the ceiling????? I only ask because I'm a firm candidate in doing things the right way. I'm also putting up a two inch wide chair railing. I purposely put all my "butt joints centered in the wall were we are installing the chair railing. I also need to know if considering my chair railing is going to be completely covering the butt joint is there any need in mudding the butt joint? I already pre filled the joint so it will be sealed. Is there a down side to not finish mudding the butt joint considering the chair rail will cover it as well???? Thanks ! I also want to give you a huge thank you for all your videos as we have learned so much and our Diy remodeling has gone better than we ever thought it would!!
Update: lol! I watched your master class drywall video "again" and it answered my questions! Sorry, I should have been more diligence. Lol! I drywalled a house i owned about 15 years ago and I was not happy at all at the results then. But this time I doing as close to how you teach as possible and I am just amazed at how good its coming along! I had a buddy come over and when he saw the results he accused me of hiring a pro to make myself look better! Lol! I can't thank you enough for your videos. Your an excellent teacher! P. S. My wife says when we are done dumping obscene amounts of money into our remodeling, she wants to send you a gift 🎁 😉 for all your help. You have literally saved us thousands of dollars 💵 !
What about information do you have about clay roofing and its life expectancy vs the others you mentioned in your video?
Great video Jeff!
I am confused with the sequence in video. You first show ice and water shield and then shingles. Then it suddenly goes to the synthetic underlayment making it look like you are putting that on top of Shingles !! So now I am not sure if the sequence is ice and water shield underlayment 3 feet from eaves and then synthetic underlayment over entire roof and then shingles ?
Great video!
Here in uk we have tiles on roof, do they use any roof tiles in Ottawa
They are extremely expensive here in Canada and very rare. We also have a much more severe climate than the UK so I am unsure whether clay tiles would hold up in the freeze thaw cycle over the years.
@Mr. Canadian dumbass Slate is a rock mined from the ground, clay tiles are baked like bricks. I see a lot of Canadian bricks failing after 30 years so I am unsure we would be up to the task of making durable roof tiles.
@Mr. Canadian dumbass No worries.
Hi Jeff. I don't know how to contact you otherwise so I'm just commenting here. I own a Condo in Toronto, one of those old pour concrete big apartment-style condos. All the walls are 2 inches poured concrete. Can you do a video on dealing with concrete walls and what I should do to properly renovate when I don't have studs. Thank you.
6:20 There's not a company on planet earth that will do as good or a better 'system' for $12,000 than the company who charges $20,000 for the same 'system.' So that's just not true. You must live in a really cheap roofing area if the range for a good, complete job, including new wood, is $7,000 to $12,000 depending on the pitch of the roof.
3 days on that one house man what 😮
In extreme heat and slopes it moves much slower than a regular pitched house. for sure.
Exactly what I said😂
Great info here. I wish I knew exactly how old our roof was, neighbors say it was probably replaced when they all got new roofs after some hail, which was 2013 or so. When selling, it just said less than 9 years old. I have architectural shingles as well. However, our attic up until last month had poor insulation and air circulation so I finally had that fixed up for ice dams. I'm guessing the multiple years of damming have dropped some of that life expectancy (thanks previous owners 🙄). I also am not sure whether they got it done right, judging from everything else I wouldn't be surprised if they got the cheapest bid so I have no idea how they built it and whether there's proper components for water diversion.
So far visually inspecting the roof, it looks like it's doing okay, I've been up there a few times. Discovered some nutty things though like a vent going up and it wasn't aligned with the cap so there was gaps where rain could easily just go straight down into the attic 🤬 Replaced the cap on it to mitigate that but jeez.
Sounds like you are keeping yourself very busy. I’m in the market for my first home purchase and my favorite house looks like it needs a new roof. Good luck to you!
good job
I really appreciate all the instructional videos you are doing but I strongly suggest you make a supplemental video to this one as critical factors such as drip and rake edges were neither installed nor discussed and no comments either about step or kick out flashing. You are so good in discussing code changes and innovations but a few key points were missed here. Without proper flashing the roofers are going to use a lot of caulking to try to seal roof/wall joints which will never last as you know. These items have to be discussed upfront and can explain pricing differences between some quotes as well.
I like roofing!
Good commercial. Can you recycle aspalt roofs?
i think you meant " don't be afraid to go with an architectural shingle roof" instead of 3 tab. 3 tab is the lowest quality shingle..
LOL, YUP! did you see his face!
I'm pretty sure they were stapling the shingles down. I know for sure they stapled the starter shingles on.
Multiple issues already. Not peeing the ice shield. Not re-felting. I would be weary of this install Jeff
Peeing on the ice shield? Never heard that term before...Meaning?
You can’t peel ice shield back lol unless you take the decking with it haha
Plus i didnt see drip edge
Man this job is whack, and he said 3 days for the install 😂 my crew will have this done in less than a day..
it makes me so happy to see workers on a roof wearing safety harnesses. scares the crap out of me to see people just freestanding on roofs
Roofer here - If you had worked on roofs, you might think the opposite. It’s quite safe - safer than people think.
Roofing is sketchy. It's good to see the ropes come out. I see a lot of crews skipping the ropes.
Amazing! Then there's me on my knees clawing my way up a 6/12. One of the few times I'll admit I look like a sissy.
I had a chance to make amazing money being a roof estimator and I literally couldn't even talk myself into getting up on the sketchy roofs to give a quick analyze.
Thank you for this video.
Hey Jeff what is that red sq drive bit you always use? Where can I get that thing at? Cause as much as you use it that thing looks like it never wears out haha I need one!
3 days?! If my crew took 3 days to do a house this small they would be kicking rocks. You have to take off all the felt to inspect the decking. You never want to lay ice and water over tar paper and you need to take the backing off. There needs to be more than 4 750 vents on a roof that size. You need proper ventilation.
6-12 pitch here 3500$ gaf 50years . You are right one phone call.. one day and a new roof, it was easy! Btw your roofs are expansive in Ontario 🙄
My roofer cousin and I put the 3d " architectural" shingle on my double wide 2yrs ago. I chose to put the "ice and water" over the whole roof. I figured better safe than sorry since I live in the cone of uncertainty in NWFL. It still looks great and has no leaks after Sally.
It's a lot easier when u have planks and ladders they pay for themselves in no time, still use ur harness, but it's way faster and easier
Do not buy a flat roof! I've work on several jobs involving leaks in a flat roof and they are a pain in the ass. Biggest problem is the difficulty in locating a leak, that water can travel the whole roof system (after finding a penetration point) until it finds a weak point which could be many yards/meters away and now you have an entire roof to tear out.
I don't quite understand why the old tar paper didn't get removed considering they used a better synthetic underlayment anyways but I'm not a pro roofer so must be a reason...? Regardless, I'm in the process of re-doing my 9/12 pitched roof and with 3 layers of asphalt there is absolutely zero chance I could save the old tar paper.
