The first drawing is showing the TPO stuck to the top of the roof, and to the vertical edge of the roof.
If I apply pressure at a lower part of the TPO handing down, (red arrow), what tends to happen is shown on the right.
There winds up being an air gap towards the bottom edge, which can't be removed. Fortunately, I don't have any of them.
In this drawing, what is shown, is to apply pressure towards the top of the loose TPO, so that the very edge gets folded first, and the edge adheres before the rest of the TPO is mated underneath.
That is shown on the right side of this pic.
If this was a thin TPO, it would be much easier to bend around the corner, but since it is .060, and fiberglass reinforced, it doesn't bend very easily.
I did do this when the sun was out, and had warmed up the TPO, and that helped a lot. I don't think I could have done it if it was cold.
I suppose I should have some type of U shaped device, to force the TPO up against the bottom, from the outside in.
I am not sure yet, I guess I'll have to play around with a couple of test pieces before doing the other side.
I must say, I didn't see this one coming.
