Polyester fabric Roof?
I came across this roof.. if you can call it a roof system. This roof system consists of polyester fabric embed in elastomeric coating directly over the top of plywood, The overall thickness is around 20 mils thick. The coating should have been at least 30 mils thick and the membrane should have been 60 mils. This is a prime example of buyer beware. The home owner paid $2300 for this. I replaced this roof with a 1 inch foam roof with 3 coats of elastomeric coating @ 1.25 gallons per 100 sqft. for the same price. I’ve talked about polyester fabric before and it’s use for repairing foam splits and for the use on top of stucco parapet walls to stop cracks. But this is NOT a roofing system and anytime someones says their going to put polyester fabric on your roof ask these questions.
1. are you putting over the exsisting roof system? (this is ok for a band-aid)
2. are you going to tear off the exsisting roof and put this in place of it? (this is not ok)
I’ve seen this used as a roof system before (and I’m not to fond of it) But it’s applied totally different then this roof. When this is used as a roof system the polyester fabric is layered in asphalt emulssion and the final coat is a 4 gallon per 100 sqft elastomeric coating achieving an overall mil. thickness of around 140 mils thick.
