[sourdough]

I've recently had what appear to be roof screws pushing up on the edges of my roof, not in the area you have. I cut 4x4 sections of Eternabond tape and centered them over the areas that were pushed up. Further action may be required but I don't think so. I also had the silicone issues you mention. I used alcohol (70%?) with a rag and rubbed them down. Worked well. Mine was still in excellent shape once rubbed down. They looked like the edges were just fly away but the actual seal was good. I'm not sure that Dicor is going to stick to silicone if left in place, and as we know, silicone removal is a real pain.
