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.

If you are in a hurricane-prone area or are exposed to winds in excess
of 60 mph, you need to plan for a roof replacement with a material that
will withstand those winds. Shingles are not one of the options.
Consider either metal roofing or adhesive-attached tile.
