I love seeing a family working together and you have some amazing sons with you sir! And thank you for the video, I’m currently dipping my toes in repairing a roof here at my job in seward Alaska with a bad water leak from a neighboring roof coming into our communal kitchen we have here.

[@travissmith3720]

Wow , kind of different than the way I torch. I will need to get my video going on my next torch down job. For when I want to seal the torch down to edge metal I would instal about a 6 inch strip of torch down first , then metal , then the top layer. So I'm sandwiching the metal to the touchdown.

[@bobbarker9986]

I used to do that too with 9" strips but it doesn't really work as great as it sounds because to get the strip hot enough to melt the torch to the back of the metal you end up putting too much heat on the metal and it warps. I guess even if you don't melt the first layer to the metal but the 2 layers melt together if water gets under the top layer it will be forced to go out to the edge of the roof under the metal instead of leaking and if you fold the base sheet over the edge it will be forced off the roof I think. At least that was my thinking.

[@kevinwaller6353]

@@bobbarker9986, put a strip granule side down and nail it on and then sandwich your metal. It won't require as much heat.

[@bobbarker9986]

@@kevinwaller6353 yes that's what I'm saying. but even better than that is to use smooth so there are no granules at all. Melt the smooth to the base sheet prior to installing the metal. Then melt the two sheets together, but to get the bottom piece to melt to the bottom of the metal it still takes enough heat to warp the metal but it usually straightens out once it cools.

Whats to stop roof from blowing off cause u did not put enough plates. Another thing i have never seen no company put this system over rocks. We usually either rip it or suck rocks off and use rubber with polyiso.

[@FlatRoofDoctor]

You are just someone taking orders. Monkey do what monkey see or told. This is a self-adhering base. No need for your "plates and screws". Also even if it was the system you think it should be, base paper with plate and screws, then the only reason why a roof would ever get blown of by wind is if it could get under the membrane. So if the edges were totally loose, and a little wind could sneak in under, it would start lifting and become a huge sail. Yes, you are right, you don't know much. I thought I was one of the first to go over the stone. I came across a few roofs that were done like that 30 years before I did it. The method you describe is 3 x more costly, and there is no reason if the substrate is still in good shape. In fact, it is far better than what you are used to. The stone act as insulation. The air trapped between the stone is a natural I isolation and also allowing moisture to move out to the sides. This type of system is a huge benefit. I guess you also don't use the ceramic granular surface, just the smooth. My suggestion is to become the best in what you do, instead of becoming a critique. You will never amount to anything critiquing others and yet you are not the best. All I do is Torch Down for the last 35 years. I don't do shingles, EPDM, TPO or metal. "I am the Flat Roof Doctor, I know a thing or two because I have seen a thing or two, bla bla bla".

Thanks Mr Russian - I am surprised to hear that they have the same materials over there. I have been installing Modified Bitumen Torch Down for 30 years. It appears that fewer and fewer Roofing Contractors are willing to install this type of material. I could be because the learning curve is higher than other materials and it is slightly more expensive. You are correct. This material will outlast any other roofing material.

[@bobbarker9986]

Finally someone who knows what he's doing! Just the right amount of heat in the right place. I like how you always keep the flame aimed towards the side seam to add extra heat, even when you are heating the other side. Like you said your son was moving too fast and not melting all the seam area, heating too short of an area and rolling to far each time. I'm sure he does it great now because you know the difference. I've got 44 years on the roof, sold my hot tar kettle in the 90s and do exclusively torch down now. Great job!

[@tooeazeful]

Hello. Water is coming in through my seams on my modified bitumen flat roof. How can I stop this?

Pop the seams loose where possible. Pry them loose from each other and re-torch. If that is not possible, then use Turbo Poly Seal with the fleece over the seams

[@nateeaston2043]

i have never went over gravel with a base layer. i have with recovery board.

[@FlatRoofDoctor]

Sure, that is what everyone does. But, the recovery board becomes a problem when it gets wet for one reason or another, either rotting, getting soggy, letting the fasteners holding the recovery board poking up through the membrane. With this method, there is air trapped among the stone allowing to air out whatever moist is trapped. And should there ever be a leak for one reason or another, the membrane will not be compromised and any leak could be taken care off.

[@kevinwaller6353]

@@FlatRoofDoctor, you can't convince me that the rocks will not penetrate that roof by walking on it. If you're concerned about recovery board getting wet at some point then use fan fold polystyrene insulation that is not affected by moisture and on top of it all it is not secured to the building. It appears to be a floating roof. I'm in Florida and there's no way you can get away with that here.

[@FlatRoofDoctor]

If you have an existing Torch Down, then you should only put another Torch Down layer over that one fusing them 2 together. That becomes the ultimate roofing system that will last over 100 years. The 2 layers become a 2 Ply system.

@@FlatRoofDoctor thanks so much for the fast reply, love all the videos . thought i knew a lot it was originally a gravel roof . it was a lot of work.

[@dogtaxi812]

Interesting video. When you install edge metal, you are using gravel stop on here, there should be a 10 in. strip of smooth torched to perimeter first, then flashing nailed. Next the flashing should be primed with asphalt roof primer. The quick dry spray is best. Then you torch your finish ply on to that so that your metal ia always sandwiched between 2 layers. All cant and protrusion areas should also be double with the finish ply. I believe the Karnak you use on flashing is for SBS cold application, not APP torch application.

[@FlatRoofDoctor]

Ok, that is all your opinion and what you have been taught. I agree to "sandwich the metal edging" The Karnak is not for SBS only. If you read on the label it is called "Modified Bitumen Adhesive". The Karnak is better than any sprayed on Asphalt roof primer. The Asphalt roof primer is just a very thin layer of the Karnak. It is not even close as good. To apply heat to the metal edging is wrong. That is why I don't torch or use a flame to attach the membrane to the metal. I apply a thick coat of Karnak Adhesive to the metal that will prevent the flame from getting to it and then melt the membrane slightly to burn the plastic protection so as to stick it to the adhesive. This is a trick I started 30 years ago and has not failed me yet.

[@davidlysohirka798]

First....rip off old roof....lay your base to all perimeters and crease over fascia 2". Install min. ga perimeter drip edge with a flange min 6" onto roof and 2.5 over fascia.....nail the shit out of drip but keep nails out of last 3 " on fascia side of drip.....prime flange...install 10" cover strip onto drip 3". When torching your cap sheet , cut 1" past drip and trim after it cools..... That's how It done! 😎

[@leog6742]

Is there a trick on how to keep the roll straight When is a long distance?

[@FlatRoofDoctor]

When you apply heat to the roll, one tends to put more heat on the side where the overlapping seam is. because of that, the material expands more on one side than the other. Overheating the seam could cause the membrane to go on a turn

I have used 3 ply modified bitumen that has gravel on top and I guess the material you used is the same minus the gravel. Why is it necessary to put down fiberglass sheet over the old gravel and over that base sheet and modified bitumen; why not skip the fiberglass sheet? Or can you skip the first two coverings and just applied the modified bitumen roll over the old gravel?

[@FlatRoofDoctor]

Ok, I am a little confused at what you are saying and asking: 1. "I have used 3 ply modified bitumen that has gravel on top" Does "gravel" mean "ceramic granules"? 3 Ply - what is each layer consist of? 2. The reason I install a "fiber base" not "fiberglass"(it is a specially designed fiber asphalt saturated paper for torch down) is because: a) it provide a smooth surface over the gravel roof b) it prevents sharp edges from piercing to the cap sheet c) it is a stiffener for the system - meaning it helps keep the cap sheet from making creases. 3. You can never install a Modified Bitumen Torch Down membrane by itself. It will start getting wrinkles over time. You need a backing like a fiber base paper 4. "I guess the material you used is the same minus the gravel" I don't understand this part of your statement either. I am confused at what you call "gravel."

[@Henry-gb8cl]

@@FlatRoofDoctor Sorry about the confusion, let me clear it up. I meant ceramic granules and not gravel. I was covering over an old modified bitumen covering that had faded white ceramic granules on top. First, I laid down a flame resistant fiberglass base sheet and fastened it to the old covering with nails with square plates on top and torched down a new modified bitumen membrane with white ceramic granules for top cover. I was referring to the new membrane as a 3 ply, only because the label on the product said, "Tri-Ply APP membrane-maybe I am wrong. I spent 2K just on materials and the roof is still leaking, a lot less, but leaking and I noticed creases, or wrinkles developing on the new covering. Did I do it wrong?

I’ve done torch down for over 25 years now and I’m a member of Roofer Union in Chicago out of Local# 11 , Roofers and Waterproofers ! I enjoy watching your videos, keep up the great work ! GOD Bless 🙏🏻🙏🏻

[@FlatRoofDoctor]

Hey Deno - You are correct, asphalt primer is the way to go. What you don't have right is you call it "roofing cement". That is the junk most roofers use. I have never and will never ever use roofing cement on any roof. Karnak 81 is not roofing cement. Karnal 81 Trowel Grade has the same components as Karnaks asphalt primer. I have been using it for 30 years and never had a problem. I have never used roofing cement in my life. Thank you anyway for bringing that out. It is a good observation and a good tip from you. Use Asphalt primer if you plan to torch and melt straight to metal. (very difficult to do, need to nail the drip edge every 3") In my case, we don't torch to the metal but instead, we use Modified Bitumen Adhesives from Karnak. Thanks again for your input - it is much appreciated

Flat Roof Doctor Always learning , we’ve never used that before or heard of it here , I’ll have to look it up ! Just curious, is that a Hot Shot torch ? They’re getting hard to get in The US , glad I stocked up ! Also, Have you ever used a Dragon Wagon to torch out the flats ? Thank you for your reply and great video 😎👍🏻

I hope your in my area if you’ve been doing this horrible quality for 30 years means I’ll be in business for years too come your doing 90% of everything wrong I am 23 and have been doing this for 8 years and I did better quality my first time on torch your using Karnak on metal that’s complete wrong in so many ways they make this called primer for metal and your standing on the roll putting boot marks all over the roof it’s crazy you even have work after your first job if you compared 1 of my jobs to yours you would be blown away at the quality and skill that you clearly lacking I feel bad for your kids getting taught how to be hacks at flaying roofing when it’s an art to be flat roofer honestly disappointed in people like you that think you can do this to homeowners that roof likes like shit and is pieced in like shit you have so much to learn so little time Also I never comment on anything but this is so bad I couldn’t help my self my jaw has been dropped the whole video

Come'on roof doctor! I don't see a fire extinguisher anywhere on this job. Gotta teach them safety unless you want the whole building to burn down. Code requirement within 10' of torch operator everyone. It doesn't take much effort to have one with you.

Thanks. I was going to ask, "what are the fire safety recommendations you would make to a do-it-yourselfer homeowner who is going to try the torch down technique?" Your answer sounds reasonable to me.

You can buy this from a Roofing Supply place like ABC Building Supply or Allied Roofing or Beacon Roofing. Those are the biggest in the country

Its Glass Fiber. Not fiberglass . Miss leading when you say Fiberglass . There's a difference . Your torching is horrible and will lead to many deficiencies through thermal cycling .

[@dustinlogan7956]

Would never pass an inspection.

[@dustinlogan7956]

I would normally use a cane to pull my roll instead of walking on it. If you tried that on a hot summer day your cap will end up with footprints (if torched properly). Pulling instead of kicking the roll allows you to control the flame and hit all areas of the roll and the base layer underneath evenly. This roof will be covered in Blisters (air pockets under the cap due to lack of heat and adhesion. The biggest mistake in this video is torching to plastic cement(mastic,bitumin,sopramastic)

[@FlatRoofDoctor]

You need the cane instead. You are correct, if you use GAF or Carlisle products, they are way to soft to walk on while torching. If you have enough experience you know which products are good to use. Experience is what you need. To much talk doesn't get you much. In this video we are torching to a MB base that is meant for torching. John Mansfield Dynagrip. Too little knowledge too much bark makes for a Puffed up head

[@bongcrusha420]

going overtop of gravel like that is going to cause blisters from any moisture geting caught in the system. you wont get 30-40 years like that lol

[@pangallie]

[@FlatRoofDoctor]

lol

[@JoeDeeper]

How much would you charge in labor on something like this?

[@FlatRoofDoctor]

Depending on a lot of factors. If it is a plain roof with no preparation and you could start torching almost right away, then around $5 p sq ft. That includes the material - Self adhering base, Cap sheet with granules and commercial drip edge. That is the basis, but then other factors must be taken into account. The bigger the the roof. the less per square feet. More obstacles, the more per sq ft. Then also, the area where you are. If you are in a city, like New York, or in Connecticut, then the price almost doubles. If you work in small towns across America, then the price goes down. I hope you get the idea.

[@johnlieb1]

u really should remove the rock so u can repair any defects in the field of the old roof.

[@FlatRoofDoctor]

There were no defects. You can tell from looking inside the building up. Your thoughts are most common to many as you. As long as there is a nice solid flat surface, I don't see why you can't install a roof over it. Your thought is to remove a solid flat surface to another solid surface (the substrate) to install a new roof. That is the most common thinking. But always more costly too. If the cost was not the issue, we might as well remove the entire structure and start over again. What about specs where they require 4 -5 layers of Torch Down? Your thought would be it can't be done? BTW, I appreciate your comment. I am just trying to let you see it is not always necessary to remove a layer of roofing.
