with the contractor...his quote faxed over was(as all three were) EDPM...no mention of reinforced.

pbs0630 · 05-05-2009, 01:59 PM

I'm not quite sure what you mean by that. I have only represented myself as a board member at a small private school in need of a roof??? There is R-30 in the ceiling space between the ceiling and roof...the sheeting is 1/2" fiberboard. I will get pictures later today. the warranty is through RPI...40 years on the membrane and 15 on labor and materials.

The first guys don't know how to spell. I think you posted the same spec twice. Looks like you corrected some typos the 2nd time and added a few words.

Me thinks something smells fishy and you aren't who you claim to be.

What are your insulation requirements in terms of R value? 1" poly iso has an R value of 6, not 8. What kind of roof and insulation is up there now? What kind of roof deck does it have.

he doesn't say he's goign to use edge sealant on the seams witht he seam tape which is a requirement by all the manufacturers I am familiar with.

Who is covering the labor guarantee? The roofer or manufacturer. I'd want that spelled out.

Is the EPDM reinforced or non reinforced?

Grumpy · 05-06-2009, 03:04 PM

All three contractors have the same proposal word for word you are telling me? Same insulation, same membrane, same warranty? There are NO differences in the way things were worded?

There are always differences which may appear subtle to the untrained eye but may be major to the quality and price. It's NEVER the same. Ever. Somethign is always different. All 3 are bidding the same manufacturer of materials? That's odd right there.

40 year warranty? wow

I am assuming the decking is wood sheathing...fiberboard is rttpically the name for atype of insulation around here.

For a wood deck I would make sure that you add a gyp layer of some kind for fire rating...

Fully adhering EPDM to a 1" board is a lil iffy too....make sure they fasten the hell outta that iso or it is going to curl....

If a roofer advertises he is going to give you 1" iso with an R of 8 beware.

I would think to give a 40 yr the membrane would have to be at least .080 with 3" tape in the seams with a 7" coverstrip OVER teh finished seam... the perimeter metal would also be a pre-fab....not .032.

You should really get a few more prices....

Grumpy · 05-13-2009, 01:55 PM

.032 is prefab. No?

Single ply, you know warranty's are a game. I think you are thinking NDL but I bet it's a 40 year membrane warranty, like a shingle warranty, which is primarily useless. "Our material will be free from defects for 40 years."

No EPDM comes with year warranty. is not necessarily pre-fab. Easily shop fabbed and delivered to site. The scope is fine. People who call themselves roofers get agitated when people arent sure of what they speak when discussing roofing. Every roofer thinks he knows everything there is to know. I personally would never recommend epdm for any project. TPO is white and much more durable to foot traffic and weathering than epdm. tpo is molecularly welded using hot air. therefore the seams are about% stronger than epdm. tpo is reinforced with polyester scrim as well. EPDM is a horrible product. Knowing today what we know, why would anyone put a black roof on anyways. Having said that though, epdm comes in white. More expensive though. Also, single ply guy was right about the fire barrier. You may want the roofer to provide the UL assembly he plans on referencing. Typically cafeteria's would need to be Class A roof assemblies. Let me know if you need any help with this.

And your qualifications are.....?

It's just too bad that some people think that they know everything there is to know. (Hmmmm?.....Where have I heard that before?)

Have you looked in a mirror lately, barging in here with a grand total of one post and expect to be declared the resident expert, whos opinion we dare not find objection with?

Now, show off some knowledge that you purport to have, instead of just being an arrogant "RooferPhobic" Megalomaniac as you sound from your Grand Self Inspired Introduction.

By the way, from viewing your profile information, I have a question for you.....

LI class=profilefield_category

About rwolfe

What is your Roofing related field/trade:

Cheif Estimator

What is a "Cheif" Estimator?

Forget it. I looked it up and NOW I UNDERSTAND.....

From the Urban Dictionary:

1. cheif
to smoke or inhale a drug more than likly marajuana
i be chiefin that good ish

2. cheif
a mug or fool, a weak person. used primarily in west and northwest london
shut up you cheif

3. cheif
Misspelling of the word Chief - mistake typically made by idiots who read at the 3rd grade level
retard on IM - "Hey cheif"
retard's friend - "Hey guy, did you mean chief? idiot"

I am glad to have had the opportunity to understand you better. I leave "Special" People alone.

Well, that was a complete waste of my time, but it sure felt good.

How about tomorrow, we wipe the slate clean and start all over again?

SinglePlyGuy · 05-19-2009, 11:03 PM

You are right Grumpy..i was thinking NDL.

3. cheif
Misspelling of the word Chief - mistake typically made by idiots who read at the 3rd grade level
retard on IM - "Hey cheif"
retard's friend - "Hey guy, did you mean chief? idiot"

That made me almost piss myself.
