EPDM or Torch Down??

Cold roofs here (on pitched roofs)are meant for cold climates to slow the snow melt process and minimize ice damming on overhangs. Global warming would lead to less of them.>>>

you need to read the name if the person replying b4 u spout off.

But, like anything else, assuming it is done correctly, EPDM is of better value and will last longer.

>>>

a hot roof has to do with the presence of heat the uderside can be exposed to. I.e a heated home has a hot roof, the soffit is considered a cold portion of that roof.

Conversely an unheated shed is a cold roof, no heat on the underside.>>>

Macroof Said: Field material degredation does not START until approx yr 45 for epdm. The life still continues many yrs post.

45 years before surface degredation begins? Bullchit! It starts as soon as the sun hits it.>>>

Macroof Said: Vaa, Hot roof and cold roof do not refer to where the insulation lies, btw. Maybe it is just another example of NZ specific terminology.

Buildings here have insulation in the ceilings as well, not just a NZ speciality.

I believe a statement in your first response to this post is still your most pertinent, and your number one reason for favoring Torch down, You are set up for it. I just hope you are doing what is in your clients best interest, not what is in yours.

Mac

VAA is using the correct terminology both in NZ nad here in the good old USA. What is the issue?

A warm roof assembly has the insulation on top of the deck, in contact with the waterproofing, while a cold roof assembly has the insulation below the deck, not as a part of the roof assembly itself.

As a super duper roofing pro, you should know this.

Is this the same MacRoofs as before?>>>

As far as production rates.... i know that one man vs. one man.... I can lay a lot more torch down than one man cold glue down rubber effectively.

I know that if we had three men working it, we could keep up on cut up stuff, while falling behind in wide open field.

I like the torch work. More like a craft than Elmer's glue-all.

And whomever said that EPDM will naturally last longer.... please show me an emperical study done on the subject so that I may be better educated if I am wrong.>>>

I`ve done plenty,where 1st thing was to tear off the bad roofs poorly torched,I would use the torchdown,Tell them the last one failed for improper installation-I also use waterproof base for torchdown,when you use that base there`s not a lot of difference between 2 ply torch or 2 ply flintlastic SA (USE PLYBASE),The last roofer had to be really horrible to screw up torchdown on a 2 on 12 pitch-GEEZ !>>>

Is this the same MacRoofs as before?

Yeah it's the same macroof, same troll, same idiot, stirring up trouble as usual. Apparently the NRCA isn't to selective about the people it elects to it's board................or the knowledge they have. ............and by the nature of his speech impediment, it appears rosyroofer is his kin.>>>

Unless ur using a paint brush to glue rubber roofing down there is no way in the world you could keep up applying torchdown. Any one in there right mind knows torchdown installs is alot more dangerous than rubber installs. The first hint is maybe the torch. Sounds as if you guys are salesmen for torchdown.>>>

Aaron, Vaa, No insult inplied here, but I assume you guys are 1 -2 man operations? If so, that wd explain your desire to utilize the systems you do. Torch down is a lot easier with one or two pple. If It was only myself and one other person, big rubber jobs wd be an impossiblility. We have the man power, equipment, and skillset to utilize epdm to it's fullest capabilitys.

Vaa, we have over a million sq's down epdm roofing, mostly with glued laps, and they are still functioning properly. The Impeteus for the tape was not so much an inherent defect in the black glue, but rather some of the "gluers". The tape is a step up.

Jed, glad you still have nothing intelligent to say, at least vaa, Aarron, et.all are able to debate, and put forth reasoning behind their thoughts and beliefs. >>>

As always! Thanks for the good time guys!

I don't always have the heat on in the shop so would my roof run Hot and Cold?

Does this hot and cold roof thing only apply to flat roofs?>>>

The cold roofs I have dealt with have been in Park City, Ut, Winter Park Colo, and Banff Alberta. All were a second layer of plywood over framing to elevate it over the first layer. The tile industry is trying to promote that, if you have a thick enough vertical stripping under the battens, you have created a cold roof.>>>

Two Nail Tony sez a cold roof is ventilated and a hot one isn't.>>>

:dry: :dry:>>>
