Can not determine from a single photo.

Appearance is indicative of several types of Roofing materials.

Hi Joe, I agree with you, the photo did not come out very well when compressed for this site, the open blister is a good clue however, but only for those familiar with these systems.

I’ll explain more tomorrow when the poll closes.

sorry to all about the image quality

Hi to all,

again sorry about the photo quality, it came out darker when I posted it.

The correct answer is SPF (sprayed polyurethane foam) the blistering is a common problem on these roofs when not properly applied, the blister is in the elastomeric covering that acts as the topcoat on these roofs.

Regards

Gerry
