EPDM or Torch Down??

Randy,

In an attempt to avoid the amazing interactions here, I'll just say this:

1. I have no idea how many squares of APP modifieds or epdm we've installed. It's been a bunch of both. Not a million squares, but at least a couple hundred thousand of each.

2. In my opinion, a 2 ply modified with full 4mm (160 mil) sheets, is one of the best roofs you get. A 2 ply Derbigum is the best, imho. Other app's pale in comparison.

3. A single ply of polyester reinforced, commodity grade APP which I would consider Firestone app 160, Manville Apex 4, Polyglass, flintlastic, et al......... is a decent low cost roof, but not nearly as good as a 60 mil, non-reinforced epdm.

4. Reinforced EPDM, particularly 45 mil, is showing a lot of problems from surface deterioration that leaves the threads exposed to weather.

5. Surface deterioration of EPDM starts the minute that UV rays make contact.

6. Surface deterioration of APP modified bitumen starts the minute that UV rays make contact.

7. 45 mil EPDM will often start to pinhole around 20 years of age. Haven't seen pinholing in 60 mil yet.

8. The vast, VAST majority of EPDM installed in the US is installed in the NE quadrant, taking in all of the great lakes and coastal region. UV is not a huge problem here for EPDM. If you live in the south, or high elevation, EPDM will deteriorate much quicker.>>>

Well, thank goodness I am not trying to impress you Jed. Or i wd be in despair.

Oh. I wouldn't go that far, embarking on an excersise in futility, yes......but then I'm sure you are used to that.>>>

Well, thank goodness I am not trying to impress you Jed. Or i wd be in despair. >>>

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.

I have plenty to say, but I don't suffer fools gladly nor mock the afflicted. You have already been kicked out of here twice that I know of for acting the idiot. If you were even slighty capable in conversing on a semi intelligent scale without the typos, shorthand text, and with a hint of roofing knowledge I have yet to see it.>>>

and yes Vaa, we have, I do not know where u got 1963 from, the parent company was actually incorporated in 1950. And that company has been installing epdm for approx 30 yrs, and yes it has been over a million, and I wd say that is conservative. That wd equate into approx 33,000 sqs per year, on avg. And no, the call backs that we have gone back to were very seldom, if ever due to apllicator error.

I understand VAa that it is hard for you to fathom a company being able to avg 250-300 sqs FA installed. But that is what the company does.

We are not a 1-3 man operation.

Hi Builder, it is a typo, the company who built the site, is not quick on fixing errors, there were a lot at one time. It was 56 sqs.

Thanks for checking it out >>>

Mac....I couldn't find an email address to contact you when I was looking at your website. I noticed a small typo that could be misleading, the one paragraph about the yellow clapboard house in Marshfield....50,000 sq ft. I can't see that that is a 500 sq job. Nice website BTW>>>

:dry: :dry:>>>

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

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.>>>

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?>>>

As always! Thanks for the good time guys!

>>>

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. >>>

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.>>>

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.>>>
