Uh oh god forbids someone gets the job done for cheaper, as long my roof dont leak I'm good with it. This guy just embarrassed a whole industry really. He just laid down a great roof with just him and his wife and it didn't cost him 10 billion dollars....what lol
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!

Turbo poly seal is $200 per gallon you have a 5-gallon bucket there that means you paid $1,000 for a bucket My customers won't pay me spend money like that
Was this the video which began with $6000+ bill for materials? So if labor costs are charged according to book estimating manuel, how much labor wage does roof owner pay?

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!

As they say, a little knowledge is dangerous. There are so many fatal errors in this roof installation, I lost count in the first five minutes. For starters, this is not a "rubber" roof, as he states. It as an asphalt-based "modified bitumen membrane. Second, it can sometimes be installed over existing roof systems, but cannot be installed over "anything", as he states. Beyond that, nearly every application instruction is incorrect. If this roof is watertight at all, it is sure to fail within a few years, max. Please do not take this person's roofing advice. People should stick to things they know!
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.

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

@@stevengee4562 I've done 1000s of meters with hot pot green mineral finish pasting over the laps so you can cut off the access bitumen which leaves a clean edge. Obviously you know what I'm talking about if you're old school 👍
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 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
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.
Everyone is looking for a fast inexpensive fix. This isn’t it. The system will work if properly applied. This is not. 39 years roofing from Built up to APP to KEE TPO PVC EPDM Way to many things wrong with this application. I bet the owner has already had to replace the roof properly
Please do not put a self adhered modified roof on like this guy. Anyone who has ever put stickers on anything knows it needs to be clean and smooth. Even roofover he could of screwed down a insulation board. The roof runs up the wall a few inches, base and cap. Then you hang a wall flashing. Why am i telling you folks what the instructions and pictures on the package say. Just read them. I am 3rd generation 38 year commercial flatroofer. If you got any questions just ask. This is not the way.
I friend of mine and I did a roll roofing job for my dad on and old rental dwelling in the rear of his former residence property here in SE Louisiana. It was very affordable and served the purpose for at least 15 years. It did have that mild slope you speak of. My dad made his Beer, Bread and Egg money from that little "Shack" in his retirement years.
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 !
Absolutely one of the worst roof installations I have seen in my 52 years of built up roofing. The entire roof should have been primed before installing the base. This roof will now blister, and start leaking 15 years before the end of its serviceable life. The flashings will ALL leak in the next 5 years. Watch some Manufacturer's videos to learn the proper methods.(GAF, Polyglas)
"We didn't use base because we were in a hurry" are you kidding me? These guys are showing 4 different applications without doing any of them properly. Absolutely do not follow any of this guys money saving tips because when it leaks your not only going to rip off twice as much crap but your insulation ceiling drywall and flooring will be in need of repair also. Go watch 50 other videos but don't watch or follow anything from this hack job. "Cheapest roof" is going to be the one that doesn't leak for 50 years!
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.
Hey, my question is what self adhering material would you use over torch down gutters on a home? I have one corner that leaks, but almost 30 years old & going strong.
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.
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.
Can you please send me the name of your products to see what I can get her in Mexico for a house my mother has that they keep redoing every 3 years. Please
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?
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
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.
Yes but there is a speciality trowel and a 7 gallon bucket of Elmer's glue sold by a second company but you have to be a preferred contractor licensed and insured

@@stevengee4562 I've done 1000s of meters with hot pot green mineral finish pasting over the laps so you can cut off the access bitumen which leaves a clean edge. Obviously you know what I'm talking about if you're old school 👍
My man is killing all the capitalist roofing cos. Good Job Flat Roof Doctor👍👍👍👍👍👍👍👍👍👍👍
Guess what else roofers lay down in straight lines with extra help from trusted colleagues. Hint,starts with a C and ends with ocaine
Don’t listen to this guy. He’s a hack job. Torch down modify would’ve been half the price and more reliable
What a hack job...trust me this is not how to do it
Yeah tell me about it not one beer can and where is Ricky and the new guy
Anyone with enough common sense knows that cheap actually means very expensive to repair, buyer, beware!
True in most cases. In this case, it is cheap because you can do it yourself saving a lot on labor. The material is not cheap
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 admire your wife. To me, this what all women should aspire to be; less Kim Kardasian and MORE hard work!
can this be installed over a metal roof?
As a 35 year roofing expert, I would not recommend it.
Yes, if you like throwing money away.
@@shawncummings4653 thank 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
He's going to roll his imported wife over it
I think it's time the old Doc retires !
Well the roof doctor has been doing this for much longer than you. His way must work.
Ok Karen!! Lol
So the pipes can I just place boots to them for extra protection? Also where did you buy the torch?
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.
Just wait for terrible weather and then do a.i. 45 minutes video on just how good it not being
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."
Truthfully as a 35 year roofer I would not put this on a dog house. Just my opinion.
@@shawncummings4653 Show us your video then. This guy has been doing this for many years with no problems.
@@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.
Everyone is looking for a fast inexpensive fix. This isn’t it. The system will work if properly applied. This is not. 39 years roofing from Built up to APP to KEE TPO PVC EPDM Way to many things wrong with this application. I bet the owner has already had to replace the roof properly
Please do not put a self adhered modified roof on like this guy.
Anyone who has ever put stickers on anything knows it needs to be clean and smooth.
Even roofover he could of screwed down a insulation board.
The roof runs up the wall a few inches, base and cap. Then you hang a wall flashing.
Why am i telling you folks what the instructions and pictures on the package say. Just read them.
I am 3rd generation 38 year commercial flatroofer. If you got any questions just ask. This is not the way.
I thought you were South Africans when you started speaking and then your son sounded American 😂.
I friend of mine and I did a roll roofing job for my dad on and old rental dwelling in the rear of his former residence property here in SE Louisiana. It was very affordable and served the purpose for at least 15 years. It did have that mild slope you speak of. My dad made his Beer, Bread and Egg money from that little "Shack" in his retirement years.
I like the whole process. I am in kenya how can I get this materials?. Do you have an agent
thank you I'm going to do my roof just like this , I got a estimate for 10,000 that's a eye 👀 opener
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 !
always lay a upside down nailed sheet around edges
Our crew always leaves extra nails for the next couple
Also way too many wrinkles
I have something with to many wrinkles that I need to rub out
Absolutely one of the worst roof installations I have seen in my 52 years of built up roofing. The entire roof should have been primed before installing the base. This roof will now blister, and start leaking 15 years before the end of its serviceable life. The flashings will ALL leak in the next 5 years. Watch some Manufacturer's videos to learn the proper methods.(GAF, Polyglas)
"We didn't use base because we were in a hurry" are you kidding me? These guys are showing 4 different applications without doing any of them properly. Absolutely do not follow any of this guys money saving tips because when it leaks your not only going to rip off twice as much crap but your insulation ceiling drywall and flooring will be in need of repair also. Go watch 50 other videos but don't watch or follow anything from this hack job. "Cheapest roof" is going to be the one that doesn't leak for 50 years!
Je suis etancheurs professionnel et j'aimerais intégrer votre équipe
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.
Hey, my question is what self adhering material would you use over torch down gutters on a home? I have one corner that leaks, but almost 30 years old & going strong.
Lots of roofers with 50 years of experience, but they dont like his methods. No explanations nor reasons, just complaining.
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.
did it pass inspection? it all looks like a big half *ss temporary repair, very sloppy wow.
Good video . How do ya know if you are allowed to add another layer ? What if a couple already ? Are there rules ? Thanks
You really have a great wife there two people makes it so much easier working together in life
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.
Can you please send me the name of your products to see what I can get her in Mexico for a house my mother has that they keep redoing every 3 years.
Please
How much does a roll weigh? Would that work for a Florida room?
So gauze & chocolate pudding is called flashing nowadays huh? I thought flashing was shiny😭
Great stuffs! Thanks Doc. Immensely enjoyed it (what about the silverly UV protectant at the end?)
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
His wife is so beautiful!
Why did they sell the roll of roofing paper if not to fix the roof? It can’t be a hack job.
What is the underlayment/membrane you're using under that liberty roof roll?
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?
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 .
He mentions the roller at 21:10 but they step on it instead.
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
@@migueldefreitas1367 yeah I s
I was thinking to myself as she's takes off the plas
😊
Thank You for this information. I will watch 20 more TH-cam instructional videos and compare techniques.
Be careful up there.
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.
Just keep in mind there is no warranty here. None of this roof membrane was installed to manufacture specs.
what about a flat roof? mine has no slope at all.
fantastic video! you guys are class acts!!!
Thanks for the video my friend❤
Hi, can you use this type of roofing on shed roof or do I have to use asphalt 3 shingles? Thanks
Was that TOILET PAPER you used for the flashing ?
Polyester Fleece
Yes but there is a speciality trowel and a 7 gallon bucket of Elmer's glue sold by a second company but you have to be a preferred contractor licensed and insured
The Catalina wine mixer
Wait. They are trying to hide some &$"$$$#
Thank you for so much for sharing, my question is that you don't need to take out of the old membrane ?
Ok Alexa turn off but first say th least intelligent video you sell me more about college
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
I am so sorry
