A properly constructedroof in areas subject to high winds has trusses attached to walls with hurricane tiedowns, properly nailed sheathing, and heavy-duty shingles. These are usually accomplished during a complete re- roofing. (Consult your local code officials for details.)

Hire Smart

According to government investigators, most roofing failures during hurricanes have been due to poorly installed shingles. Shingles that had been stapled instead of nailed, nailed in the wrong spots, attached with only two nails, or applied by a shortcut method called racking (where shingles are applied in a straight line up the roof instead of horizontally or diagonally) were more likely to fail. Roofs with shingles that had been correctly installed held up substantially better.
