It probably is a heat expansion and sudden slip phenomenon - the plastic shingles on my roof make persistent crackling sounds, like falling rain, when the sun hits the roof. We don't mind, and just accept it as background noise. If it's really annoying to the owners, I suggest someone spend some time in the attic, listening and trying to spot the boards that "snap". Once they're identified, some glue or nails could be added to lock the noisy pieces into place. I think the attic fan would be a waste of effort, as the roof is the wrong side of the insulation, and will heat up almost as much after the fan is in. The attic fan will save air conditioning costs, however. Jim Warne ...
