Came home early and saw that heavy winds head on to the edge of the roof
shingles were lifting them a few inches along one tier.

In a few other areas, the shingles were starting to lift a 1/2 inch or so.

I went up and used shingle glue and some weight plates to secure down the
worst tier. (The ladder blew down, buts that another story and I don't want
to get you laffing).

Anyway, when the winds calm, whats the best maintenance steps? Nailing
through the top shingle layer is a no-no, correct? BTW, we commonly get
substantial winds around here.

Thanks, KG
