Flat Roof-Modified Bitumen vs. IB PVC

I was told torch and nail is no good. I had someone come out and recommended a cold peel and stick roof but he did not email me the estimate and did not respond to my follow up email. That made me nervous. I'm not sure what the granule roof is but the bitumen membrane is supposed to be coated with little granules?
I had a new roof leak... then replaced 8 years later with careful screening after calling the local roofing union for some names...and it leaked within months. The same person I referred to my friend before I suffered a leak... had her roof leak within weeks. I agree that I need to find a good company with good workers. Sometimes it's just bad luck too. My rental property has leaked and destroyed the ceilings 3 times since installation. That is why I am so nervous about picking the right one for my home.
THANK YOU!

On the PVC roof was their insulation added? I wouldn't compare a two ply mod bit with a IB roof. I would do atleast 3 plys. How is the slope of the roof? Honestly a little over $1,000 a sq is not out of line at all. Of course with out knowing all of the details it could be way off. Depending on roof type and details ours come in anywhere from $500 a sq to upwards of 3k a sq. Each roof has its unique properties.

Another option for you would be to look in to EPDM, or TPO. Both of these would be cheaper then PVC but probably more expensive then mod bit.


Yeah a granule roof is coated with granules. You might check out some web sites to get your self more familiar with the products. An asphalt roof has to have some kind of protection from the son. Whether that is rock, granules or a coating.

If you have any photo's I might be able to better recommend a product.

Flat Roof-Modified Bitumen vs. IB PVC


My roof is 800 sqft. I live in Washington DC. I was given an estimate for a new PVC IB Roof system or a modified bitumen. From your chat room, I'm inclined in choosing the PVC but the price $15,880 appears to be steep. My questions: is this a fair price? Is there anything I need to know about PVC (health hazard, fire retardant, etc.)? Any insight will be at most appreciated

Dandi,

It is near impossible to tell what is fair and what is not without knowing more about the application, what is required, included, etc.

There must be extenuating circumstances for that high a price for the sf you said. Every roof is different and we don't know exactly what they are doing to yours.

As far as safety, go in and ask your local fire station what they think of PVC roofs and please post their response back here if you could.

IB roofs have a very good reputation for longevity and is a quality product from a quality company. As with all roofs your main concern should be a quality installation by a quality contractor.

Hope to hear back from you.

Thank you for all your inputs.
I did call my fire station, and they said they had no opinion concerning PVC.

Those Ib prices are stupid expensive. I can tell you for sure the material cost for a 60 mil tpo would be no more than $200 a square.
Of course labor ect is extra. But almost $2000 a square damn thats a heluva profit. Or Ib has a golden scrim.
Go 60 mil Tpo its cheap and just as good or better than any pvc.

Might want to read the sticky at the top of the forum "This is a how-to site, not a...."

Then you should really do your homework on different roofing systems and how good they are before posting on six threads nothing but basically "Put tpo on it because hey, it's real cheap"

Then try googling things like lifecycle costing and value engineering. Who knows, you might learn something

I know what the site is.
And its a how to not waste you $$ on a roof thats no better than another post.
Not just cheap but just as good if not better and definitly a greener product.
And Other than home owners Ib has almost no market share.
They cater to the uninformed.

What, Roof hater? 75% of roofs will leak within the first 5 years?! What? I can tell you less than 5% of our roofs will leak. I started this company in 2003, so have 9 years data. If 75% of our roofs leaked I would have shot myself in the head many years ago from the bothersome phone calls of customers complaining. Fixing leaks doesn't generate profit. Doing it right the first time ensures I remain profitable.



Is tpo just as good as PVC? Maybe, they have the same warranty, but I know lots of guys who will disagree. Is TPO better than PVC, I hardly doubt that. PVC costs more than TPO, hands down. IB costs more than most other PVC membranes but I think it is better than most other PVC membranes.



Dandi, In regards to pricing, $2,000 a square may not be unusual. I've done several $2,000 per squares roofs and now with code changing here in Illinois to require extra R value of insulation, I suspect I will be doing alot more $2,000 per square roofs. The aforementioned roof is 800 sq ft. Sounds like a typical Chicago 2flat. We do lots of these. They are usually about 1,000 sq ft plus walls and waste. I normally order about 15 squares of material. However what is involved is what matters. Generally speaking, I will be tearing off 4-5 layers of roofing material. The tear off takes much much longer than the install. The tear off doubles the cost of the job. Insulation is important, and can be pricey. What about the gutter, if it's being replaced that's several hundred bucks at least. What about the walls, how are they being treated? Removal and re-installation of clay coping is another couple thousand bucks. Basically what I am saying is a Chicago 2 flat when done complete and proper will easily cost in the range of $15,000. What matters more is not what you are paying, but what youa re getting. Scope of work and quality of material will dictate price.
