Help!!! LOL,
Hey Guys, I am a roofing contractor in Tampa,
I have a guy doing some foam work for me on several large flats.
The flat ares are a granulated membrane,
My questions are
the roofs have large blisters do you recommend having the blisters repaired before spray of foam??
The company I have spraying, tell me just to cut and spray over with no repair!!
also should he be using a primer before spraying.
thanks for any info.

You can "X" the blisters and nail or screw down the flaps. Or cut them out. Foam makes a great repair tool.

No primer is needed due to the tenacious adhesion of SPF (unless the substrate is unusually dirty or dusty or chalky).

have fun,
