The image shows what I believe is a pvc single ply membrane on a newly built kitchen extension. It's on a property my friend is proposing to buy. Their survey report makes no comment on the evident blisters.
Are the blisters serious enough to ask the seller to get the roofing contractor back to relay this section of roof?
