Torch on roof membrane on deck

dougger222 · 02-28-2011, 08:15 PM

Ya, the guy I know who told me this is now a high end builder (homes over a million bucks) prior to that he was a gm at the states larget Duralast roofing firm. His company put more Duralast roofs than anybody else out there. They installed roofs on the largest roofs in the state year after year.

He said he couldn't believe all the cig holes on the commercial building.

Now keep in mind this was a few years ago when the cigs were allowed to burn free. Now at least in MN they burn out right away.

85, you should quit...

Oh,

You have to think a head when your doing a flat roof for a 18 year old who brings in $80,000 a month not required to work. Every base must be covered to insure a "leak proof" roof is installed.

One cig burn causing a leak resulting in an entire deck being removed? No thanks.

We do rubber roofs too, just when the roof is too flat for torch down or if the customer requests the cheaper route. Roofers that know what they are doing can do a very good roof system with torch down. My dads got torch down roofs still holding back water some 25 years later.

Well no burn in 45 mil EPDM after around 5 mins of it sitting there. I know I need to stop, now more then ever. Cig burns are not a material or workmanship problem. They get to pay for that, decking removal and all. I agree with you statement though. Duralast =

. I really do not like them. Most of the DL roofs I have seen are 40mils. They just do not seem to be the cats meow. Torchdown roofs are good, not many people have the skills to run the torch, most so direct over a plywood deck. Plus the owner doesnt like to do them any more, so the dragon wagon just sits on the shelf.

Insurance is also very high when you put an open flat to a roof! Could have sworn the last rubber we put down was 60 mil.

You must not have the cigs in your state that burn out right away...

60 mil is more common, I just used a chunk of 45 because it has been sitting out side in the sun for a few years. I figured it would be more "real world" test. Yes they burn out faster then they use to I had to keep it going every once and awhile. Still though we have used EPDM as a tie off on reroof we were replacing a ballasted EPDM with a BUR and would mop the extra EPDM for a tie off each night, I know you let the asphalt cool and all before sticking it but it still is got to be close to 300 deg. Im not saying this is GOOD for EPDM but never have burned all the way. I think TPO and PVC would be a little more heat sensitive. Guess I could test that too some time. Could use a heat welder and set it at 400 or so deg and see how long TPO takes to burn and EPDM takes.

Never worked with Duralast but suspect it to be thinner and burn through faster than EDPM or other single ply flat roof systems.

One thing I know about it is it's not cheap!

Duralast is cheap, to install that is alot of the times they just lay over the existing roof, sometimes very poorly. I have no idea what it would cost to buy their prefab roof. Im sure more then if you bought roll goods. not very good IMO
