Are there any roofing contractors or (or someone knowledgeable about membrane roofs) on the board? My father-in-law had a rubber membrane roof put on his house in Colorado less than 2 years ago. The contractor screwed up the installation so that the membrane has become detached from the roof deck. It doesn't leak (yet) but it has bubbles in it. Questions: 1) Is there some way to re-attach it to the deck without having to replace the whole thing? I know it wouldn't be recommended, but could the membrane be lag screwed to the roof at say, 2 ft intervals with a large washer and an epoxy seal under each screw? 2) Would it be possible to cut the membrane a foot or so below where it ties under the shingles of the pitched part of the roof? The idea would be to use the remaining strip of membrane as flashing and then install a conventional tar and gravel roof on the flat part where the membrane roof currently is installed. The reason for doing this is that he's gotten a very expensive bid to replace the membrane part of the roof because it ties under the shingles of the sloping roof above. 3) Can bricks or something similar be place on top of the roof to hold it down to get it through the winter? High winds create a vacuum and have created bubbles in the membrane. He's probably going to have to sue the contractor, but winter is just around the corner in the mountains, and he needs answers fast. Thanks.
