I’m a commercial roofer. Have roofed some of the highest profile roofs on Earth. This guy’s a hack. So much hackery I legitimately don’t know where to begin.
I have a bakery that I have patched the roof on for 25 years. Each year I got better. NOW I can put a new roof on because of your video. I watched most all of them. (No way my wife will go up there). This is my first comment ever. I have to let you know I appreciate your work.
I don't recommend you to do what you saw in this video unless existing roofing surface as sound as it is here and it's slope is a little bit steeper. The installers did not pay good enough attention to overlap seems, besides should use a heat- gun to weld together. I recommend you to find a roofer with experience and install a torch-down modified roof on your flat roof otherwise you can end up with more problems than you bargained for.
Ya he made a lot of mistakes that may come back to haunt him. But, Im a bonified roofer. I had my license. Retired now. All you wanna be's give him a break! You know this man put a lot of confidence in people who needed an answer to their roof issue. He made it look easy and very entertaining. You guys know dam well this roof may never leak. He did some things you called out right away without remembering that the rain was coming. How would you have sealed that edge? By torching it! Wrong! He did it right cuz he had to come back to it. Good job, Ol man.
@@AlloyedFrequencies you stated that he made a lot of mistakes and you didn't mention a single one and then you say way to go, which is it? Name those mistakes Educate us.
Sorry it was not a bad try for doing yourself but it was inproper installation. As a roofer for 25 year I'll tell you what you did wrong. Before you lay out the base you have to apply primer which some roofer call glue, the second thing you did wrong was when you installed the cap sheet you have to stagger it from the base so the laps don't land on the same spot you had to cut the first roll of cap down the middle but I would have cut was the base so I could start with a full roll of the cap the way you did it if one of the laps fail the lap underneath it could fail to because of the trapped water. I don't know where you live but if you get winter weather that will be an issue.
Your installation on the pipe is wrong you are supposed to install a cone over the pipe then put a piece of base down on the cone then put you cap on and it would be in 2 piece s so it wouldn't look like garbage you lay out a piece to pass the pipe cut around it the next piece 6 inch overlap the other way on the pipe and it's good to go and looks nice too and don't forget to use asphalt primer on the cone
Allsand is meant as a last resort of large pipes that they don't make cone inserts for not a wash room pipe and your wash room vent pipe you should have risen it up that cap comes off and you should have built it up with 2 layer of 2by4 and flash it in with your base and cap sheet it you live in an area where it snows you are going to have problems
Finally, a YT video with American contractors demonstrating the process, using materials available in the US market! I’m not necessarily “Made in America” for domestic products sake- just for some reason all the YT videos I get are from UK! I am gearing up to tackle my first EPDM garage very low slope roof. Joists, sheathing and roofing all gone south.
This looks like a potentially AWESOME product. Clearly it has ease of APPLICATION. Next test is PERFORMANCE (i.e., no leaks) and then LONGEVITY. (Those are the three test and the final TEST or issue is PRICE.) $2 psf is very tolerable if the performance is good and the longevity is long.
Materials and Labor ! for roofs with complete tear outs and new roof can be 3x materials $5K will get you $15K final ! Always always get many bidders and learn from the bids !
Nice job! This is one of the best videos on the application of APP membranes. The video gives complete details right from the cleaning of site, application of Primer, Fixing of APP sheets with hot torch method & finishing with siliver paint.
when you do a new installation of peel and stick its a 3 layer process versus 2 and it's just as effective as torch if done properly. If you a layover is just a bandaid youll be really surpised how many homes make it 15-20 more years with a band aid.
I think that's kind of the idea given the title of the video. It's the old saying in business... "you can have it fast, right or cheap... and u can only pick 2." This was fast and cheap, not necessarily "right" according to pro-roofers. BUT, for a homeowner w a bad leak who is desperate for a fast & inexpensive solution (that doesn't necessarily need to last 10 years) this video is semi-helpful. I don't even have $2 to spend per square foot so I'm totally screwed. Was considering using 4x8 coroplast boards ( only cuz i have like 100 sheets just sitting in my garage) to go over the current roof (glued down). Then i want to tape the seams with EPDM tape and coat the entire surface with expoxy resin. Then put on new perimeter flashing. I realize I'm going to create more issues but I'm stuck and SOMETHING must be done ASAP. Unless some roofers want to donate their labor AND materials, I'm on my own. Water is a sinister foe!
Great video.... I see 2 problems 1: you always have to cut your first run of S A base in half alway. To prevent a lap on lap Meaning when you run your cap sheet you're gonna have a lap on top of the other lap thats not good . Cutting your first run in half prevent this . 2 : You need to use an 80 pound roller . The roller is used to remove any air pockets that may be trapped in between the materials. In the summer when its hot the gasses starts to build up in the pockets causing the material bubble up or causing the material to separate in time .
Stepping on it and not pass the roll on it is the same thing and he also didn't use primer on the roof before he installed the base sheet some roofer call it glue
That underlay is awesome not seen that in UK. The only worry i have is if the old roof was leaking anywhere there could be rotten boards under your new cap felt? I would always recommend a re board and felt where possible, What do i know you are the flat roof god haha love your videos thanks for the refresh i have one on next week unfortunately with a leak which most likely will need new boards fitting.
Nice to see a new video. And how about you pros, working a five gallon tar bucket with clean hands! I have a flat roof with a slight pitch, so I’ll stay tuned. Y’all make it look easy. Thanks from Michigan.
I agree with Steven Gee. Also, you should NEVER run ur base seams within a minimum of 8 inches from ur cap seams. He is pretty much right on top of the base seams. That ruins the whole point/value of having a 2 plied roof. Now it’s basically just really thick single plied roof. JOKE!
Great video, i have a 3-12 pitch roof with shingles is this too steep; will the shingles and under lament need to be removed before applying this peal and stick base and top?
I enjoyed your video. Thank you for posting it. That said I have a couple of questions. I am about to venture into doing a roof in a commercial property of mine after I got quoted a ridiculous amount of money to either repair or install a new roof on a 4500 square feet roof top. On your video looks like to just put the new roof membranes atop the old roof. I was under the impression that the old membranes or old roof had to be removed? Please advice. Thank you very much . Sami
Great video Roof Doctor. you have inspired me to fix my mobile home roof. I was wondering if I could buy a few minutes of your time for a video call or phone call to let you see my situation and recommend what approach to take, be it peel and stick, torch down or some other kind of approach.
Not everyone has a wife like yours and mine. Mine has always worked with me since we been married, we were were self employed all our life, married 50 years this year
Most counties of the USA allow a max of 2 layers to a flat roof (check with YOUR a county building Dept). After that you have to remove the old down to the plywood strata. Also, roofers comments indicate and 80 lb roller is needed to rollover the material.
I am in South Florida and this roof has to pass an inspection by a licensed roofing contractor to get insurance. While it looks simple, we do not know if this DIY approach will survive heavy winds, high heat, and torrential rains…sometimes all at the same time. I really wish it were this simple and affordable and appreciate the information, but the comments by roofers point out many potential problems with the installation.
In south Florida you're not allowed to put roll roofing over an existing roof layer. "TopShield Pro underlayment roofing systems membranes shall not be applied over an existing roof membrane."
@@jamescole3152 I don't need to show anything. I have been roofing all through the US. As a speacilst in government roofing. I don't need to prove a dam thing to you.
I have been roofing for 25 years. That type of roof is not made to be installed over an existing roof without an ISO panel or clean sub. It also needs to be rolled down with an 80 lb roller to bond materials. It specifically tells you not to use torch or flame. You are supposed to use a hot air gun. Its not a torch down system. It will def be a problem
Ok truther that's your third worning I'm not going to write you up this time though looks like we're going to need you tomorrow but mostly it's forcuz I am no longer read and rite be cause this video break me mind not work
Do u have a list of everything u used and where u possibly bought everything u used. I live in Pennsylvania and am not sure where to buy everything we need and need to know how to extend our roof out to add gutters to our lower deck
As a 35 year roofer I have never seen such a thing in my life. But I am not a fan of recovering any roof. Any one who has tore off two or more layer's of roofing know's what is going on with the roof under the top one. Old roof continues to decompose, witch takes away from the life of the new installed roof. Even if a recover board it put down. And at min and install some one way vaper vents, so hot condensated air can escape.
a lot of effort to go get a tool and do a little cut. The hole is never in the right spot so you still have to cut slits to move the membrane around to position it
You give a warranty on that work? Been roofing all my life, that is a easy roof to install,that's facts,,it's just not the best flat roof system to install on that building,it's one of the worst in my opinion..tpo,,epmd,even hot tar is better than that peel in stick...with that roof having walls going down both sides like that & all the penitrations coming through the roof,I would of went with epdm or tpo just my opinion,,using a sealant for flashing is only temporary...
What is cashier over the rubber? Water shield ? I'm in WI shop Nenards. Trying do mobile home addition with flat roof. How do I get rubber roll up on roof by myself?
I like to do the same to my low slope roof, but there is a L section need the edge that as a slight U indented area that collect water and it moves to the drain pipe. How do I shape that to the old roofing? Can I use a hand torch to finish the edge?
What causes the granules to come off a torch down roof like that? Have a 5 yrs old roof, has lost considerable granules, they clog the scupper box which requires us to clean it out 2x a year. We are going to have to silver coat soon otherwise the roof will be too exposed to UV. It's nuts for a roof to start failing that quickly but from talking to supply house, granules coming off is becoming more and more common
Hi, my name is Vick, I leave in North East Maryland, I have a flat roof with TPO material, it's old and starting to lick every time when is raining, what you suggested to do ? Can I use the same materials you were using on this video ? What should I do with the existing TPO ? Can I install on top of that or I have to pull all off ? Please let me know. Thank you so much.
According to what little you have stated it sounds likely that the roof in question should be torn off and stripped down to the deck of all old materials and any rotten plywood decking removed and replaced with new before a new roof is installed. If you have had substantial leaks then there will be moisture trapped between the old roof and the new roof (wet insulation board & rotting plywood) creating water vapor which must escape and will only cause further damage to the ceiling underneath ( stains, paint blistering, bubbling, peeling, mold) and bubbling, blistering and eventually compromising the roof above for more leaks. You could potentially use a peel & stick base sheet over a mechanically fastened 1/2"×4'x8' insulated sheet of blackboard on the deck followed by a granulated peel & stick cap sheet but the devil is in the details (i.e. penetrations (pipes, skylights, drains, tie-ins to other roof systems & perimeter terminations (i.e. shingles, metal, wall flashing & metal drip edge, etc.) and this video is not a good representation of the proper application process. My advice is to research the proven work history of licensed & bonded roofing professionals in your area and get several quotes on a peel & stick replacement roof and go from there.
I have a torch down roof with leaks. The rolled roofing has white gravel on top. Can I patch over this white gravel roofing? Seems that the patched of new roofing won’t adhere to the old roofing with the white gravel
Yes it will if you have the right materials. Some are used for adhering the cap sheet and some are used to flash. Make sure if there is metal to get some primer first. Get the quick prime and you can flash right away and also get the white granules to cover your patch and if you got the right stuff your repair should look like it was still brand new haha
*QUESTION: Wouldn't it be easier & cheaper to use liquid rubber, and the sprinkle it with fine gravel for the UV protection?* There would be no seams, and would save a ton of time/labor.
@@thomasg4324 It depends a lot on thr country. In the UK there are a few other methods that are being used. One of them is EPDM, which is a rubber membrane that comes in one sheet (up to a certain size) and you glue it to your substrate(mainly timber frame). There are also liquid rubber methods that are being used but there's just something about them that makes it a bit more not trustworthy especially when compared to a one sheet option such as EPDM. Also, in terms of longevity, EPDM can easily last 50+ years.
I have a question about roofing, I have gotten several contractors over to give me estimate for replacement of the roof every last one wants to install edpm roof material over the current roof, ( old roof hot tar, last roof torch down bitumen) they all want to do only third roof of edpm . Why? Why won’t anyone remove the old roof fix the old Douglas Fir t&g decking and torch down two layers over fire resistant paper? Your demonstration of this project video is showing proof of why they don’t want to do any roof removal and repair. They can complete the entire job in one day. No old material to dispose of. No complicated process. Minor torch around the edges. Maximum return on their time. My flat roof is pitched both sides to the middle and a scupper with a drain pipe in the center. Where can I obtain the materials from your video? I’m not about to do the work myself but it’s possible with some help to complete the project in a day and complete the flashing process without worrying about complicated step flashing or anything else. Thank you.
EPDM is the worst type of roofing material do have on a roof. You are correct in all the other points. You can hire a few handy guys and have then do your roof with little cost. No need to strip the old roof.
Sometimes Home Depot will carry the Liberty Brand od Peel and Stick. But any roofing supply place carry this material. Beacon Building Supply, ABC Roofing Supply or any other local roofing supply place. The Brand does not really matter.
Reject those bids and keep requiring your specifications only ! Many regions of the country have bad contractors ! Break down the roof work scope into, tear down demo, roof repairs if any then actual new roof area if any ! Doc is right you can re-layer if needed ! Keep calling for free and sane estimates only ! Good handymen with insurance bond can do small if needed !
Just curious, why not the first Base sheet layer? In your other videos I see that you put a Base down and then the sticky second base layer before the cap sheet. I am going to do a mod bit roof just like this video with the self adhesive. Thanks so much for your info guys...you are going to save us lots of dough!
I really love how simple this roof material goes down

I think the part where you torched and glued will leak overtime. The proper way is to install the ridge and overlap the tarp.
good video but that is 1 part was a very bad instruction...

I have Henry 887tropi cool silicone put on flack roof but have some bubbles how do I fix still use silicone or use different material
As a 35 year roofer I have never seen such a thing in my life. But I am not a fan of recovering any roof. Any one who has tore off two or more layer's of roofing know's what is going on with the roof under the top one. Old roof continues to decompose, witch takes away from the life of the new installed roof. Even if a recover board it put down. And at min and install some one way vaper vents, so hot condensated air can escape.
You could get coring drill bits for cutting out the hole for the vents or maybe it won't work? What do you think?
a lot of effort to go get a tool and do a little cut. The hole is never in the right spot so you still have to cut slits to move the membrane around to position it
@@FlatRoofDoctor I see. Thanks.
You give a warranty on that work? Been roofing all my life, that is a easy roof to install,that's facts,,it's just not the best flat roof system to install on that building,it's one of the worst in my opinion..tpo,,epmd,even hot tar is better than that peel in stick...with that roof having walls going down both sides like that & all the penitrations coming through the roof,I would of went with epdm or tpo just my opinion,,using a sealant for flashing is only temporary...
What is cashier over the rubber? Water shield ? I'm in WI shop Nenards. Trying do mobile home addition with flat roof. How do I get rubber roll up on roof by myself?
I like to do the same to my low slope roof, but there is a L section need the edge that as a slight U indented area that collect water and it moves to the drain pipe. How do I shape that to the old roofing? Can I use a hand torch to finish the edge?
You don't, you foolish Americans, this roof is like a mahgwi don't ever get it wet and never ever step foot on it after midnight
What causes the granules to come off a torch down roof like that? Have a 5 yrs old roof, has lost considerable granules, they clog the scupper box which requires us to clean it out 2x a year. We are going to have to silver coat soon otherwise the roof will be too exposed to UV. It's nuts for a roof to start failing that quickly but from talking to supply house, granules coming off is becoming more and more common
What products do you use? What about the sides?
She's a beauty. You're a lucky man.
Can cap sheet handle foot traffic?
Could you please post the list of all materials needed to purchase from this video.
Where can buy this black paper they dont have in home depot or lowes
Did he remove the old roof membranes before placing the red backing pieces?
Can I roll it over a flat roof that already has elastamoric coating?
Good overall but no flashing? And I say invest in a 80 lb roller and dog ear the corners on the over lap you got this doc
I just took a selfy of my flashing on the roof hang on I'm still posting the pics
Very informative!
Hi, my name is Vick, I leave in North East Maryland, I have a flat roof with TPO material, it's old and starting to lick every time when is raining, what you suggested to do ? Can I use the same materials you were using on this video ? What should I do with the existing TPO ? Can I install on top of that or I have to pull all off ? Please let me know. Thank you so much.
According to what little you have stated it sounds likely that the roof in question should be torn off and stripped down to the deck of all old materials and any rotten plywood decking removed and replaced with new before a new roof is installed.
If you have had substantial leaks then there will be moisture trapped between the old roof and the new roof (wet insulation board & rotting plywood) creating water vapor which must escape and will only cause further damage to the ceiling underneath ( stains, paint blistering, bubbling, peeling, mold) and bubbling, blistering and eventually compromising the roof above for more leaks.
You could potentially use a peel & stick base sheet over a mechanically fastened 1/2"×4'x8' insulated sheet of blackboard on the deck followed by a granulated peel & stick cap sheet but the devil is in the details (i.e. penetrations (pipes, skylights, drains, tie-ins to other roof systems & perimeter terminations (i.e. shingles, metal, wall flashing & metal drip edge, etc.) and this video is not a good representation of the proper application process.
My advice is to research the proven work history of licensed & bonded roofing professionals in your area and get several quotes on a peel & stick replacement roof and go from there.
I don't even think im lying down for bed anymore
I don't think I am going to work tomorrow all off a sudden something just seems suspicious
Wow , nice family, but you’re roofing technics are wrong wrong wrong ,, maybe ok for a shed at camp , but nota house or commercial building ,,
ok
Where can I buy material. Have 35x40 flat roof. Please help, Thanx
Would really like to know what the material you used?
Put the adhesive on a rag inhale and you will figure it right out
I have a torch down roof with leaks. The rolled roofing has white gravel on top. Can I patch over this white gravel roofing? Seems that the patched of new roofing won’t adhere to the old roofing with the white gravel
Yes it will if you have the right materials. Some are used for adhering the cap sheet and some are used to flash. Make sure if there is metal to get some primer first. Get the quick prime and you can flash right away and also get the white granules to cover your patch and if you got the right stuff your repair should look like it was still brand new haha
@@garrett3113 thanks
Great video I enjoy Watching your wife; son and you working together Congratulations
*QUESTION: Wouldn't it be easier & cheaper to use liquid rubber, and the sprinkle it with fine gravel for the UV protection?* There would be no seams, and would save a ton of time/labor.
Degrades too quickly, cracks, splits, etc.
@@thatguy4234
Not tar...liquid rubber.
@@thomasg4324 It depends a lot on thr country. In the UK there are a few other methods that are being used. One of them is EPDM, which is a rubber membrane that comes in one sheet (up to a certain size) and you glue it to your substrate(mainly timber frame). There are also liquid rubber methods that are being used but there's just something about them that makes it a bit more not trustworthy especially when compared to a one sheet option such as EPDM. Also, in terms of longevity, EPDM can easily last 50+ years.
It would be much faster and cheaper to use spray on emulsion with pea gravel.
@@shawncummings4653
How much cheaper? Are you suggesting liquid rubber, or tar?
I have a question about roofing, I have gotten several contractors over to give me estimate for replacement of the roof every last one wants to install edpm roof material over the current roof, ( old roof hot tar, last roof torch down bitumen) they all want to do only third roof of edpm .
Why?
Why won’t anyone remove the old roof fix the old Douglas Fir t&g decking and torch down two layers over fire resistant paper?
Your demonstration of this project video is showing proof of why they don’t want to do any roof removal and repair.
They can complete the entire job in one day.
No old material to dispose of.
No complicated process.
Minor torch around the edges.
Maximum return on their time.
My flat roof is pitched both sides to the middle and a scupper with a drain pipe in the center.
Where can I obtain the materials from your video?
I’m not about to do the work myself but it’s possible with some help to complete the project in a day and complete the flashing process without worrying about complicated step flashing or anything else.
Thank you.
EPDM is the worst type of roofing material do have on a roof. You are correct in all the other points.
You can hire a few handy guys and have then do your roof with little cost. No need to strip the old roof.
Sometimes Home Depot will carry the Liberty Brand od Peel and Stick. But any roofing supply place carry this material. Beacon Building Supply, ABC Roofing Supply or any other local roofing supply place. The Brand does not really matter.
Reject those bids and keep requiring your specifications only ! Many regions of the country have bad contractors ! Break down the roof work scope into, tear down demo, roof repairs if any then actual new roof area if any ! Doc is right you can re-layer if needed ! Keep calling for free and sane estimates only ! Good handymen with insurance bond can do small if needed !
Awesome !
Just curious, why not the first Base sheet layer? In your other videos I see that you put a Base down and then the sticky second base layer before the cap sheet. I am going to do a mod bit roof just like this video with the self adhesive. Thanks so much for your info guys...you are going to save us lots of dough!
You missed it. That is when I go over gravel and tar roof
His base layer is SA. He already has a torch down roof.
Where do you purchase the materials
