Why Did My Roof Shingles Blow Off ?!?

After hearing from several home owners, and in the news, of roof shingles being blown off, I decided to do a google search.  Other than severly deteriorated shingles, the main reason for them being blown of the roof is due to improper nailing - either too far from the shingle edge or at too high a pressure, causing the nail to "punch" through the shingle.
