Black TPO. I still don't know why it fails on the *inside* of a field lap. [IMG]http://i80.photobucket.com/albums/j175/Roberts406/Roofing/blacklapsplitinsideedge.jpg[/IMG]

White TPO making me money. Looks like the installers got a wrinkle in the membrane laying it out and kinked it. Top layer of membrane already split. Safe bet it'll either de-laminate or split all the way through soon.

Cyberian,

Like you, I've seen little in the way of good from TPO. All but one have failed inside of 9 years, and that 1 got milked along for years before being approved for replacement in the budget at 15 years old.

It was doing what TPO does. It shrunk to the point that it "blew up" and had even torn the polyester scrim at the field lap. The whole roof (~60>>>

Heh, no I wouldn't coat it, but I had fun peeling it off.

Never did find out exactly what the coating was, but it obviously didn't work. It never did stick to the TPO and made me miserable trying to find the membrane splits under it.
