Only 2 screw hole for leaks! If it stays put good idea.
(Just my opinion)I have a TPO roof. I would sure re-think TPO if it were me. Everytime you do something on the roof you have to make sure the right stuff is used. I use the 2 part especially made for TPO from Dicor. Dicor also came out (with in last year) with something on the front of tube that says "safe for TPO*" then look on the back the asterisk really means, which is "safe for MOST TPO roofs" How do you know your roof is one of ones that "most" it will work? I guess wait till you get a leak? Maybe too late by then. Again just my opinion, trying to save you a hassle I go thru.
Well it was 4 screws but I see your point. I was attracted to TPO because of no black streaks and I am planning on using a Firestone TPO and their adhesive. The adhesive is like an epoxy whereas every edpm roof I've installed uses a waterbase glue. I know TPO does wick water if it's not sealed properly so I'll seal top and bottom of all screw rails.
Do they allow 303 to be used on TPO according to your instructions? I am hoping that the way I install the roof membrane will be better than the factory install. I have seen some poor work in the last 30 years especially in areas like the roof and underneath.
Does DICOR allow Murphy's Oil Soap? I have used a bunch of products on rubber roofs and they never do what they promise. Thank you for your comeback.
