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.
