I have a small low sloping roof that needs to be re-roofed. Three contractors looked at my 2 on 12 roof and gave me proposals for three different GAF products. Which one should I go with and why?
SBS Modified Bithumen Granular Peel and Seal
.60 mil single ply EPDM
Depends on what youre really looking for. T.P.O will probably be out of your price range as well as rubber. Most customers I deal with want the Liberty Base Cap and Sheet from GAF. That is what I use. Best protection for the price and it can also match the color of your roof. I assume the guy with the S.B.S would be using the product I just mentioned.
The difference in the cost of the TPO over the rubber is about $400.
I wanted to know what the difference in performance was.
Should one of the three outlast the others by a long time?
Is one a better product to protect against leaks?
The weather in CT is just starting to get cold is there an advantage of one over the others in cold weather application?
