What this means for your roof
Owens Corning explains how overdriven nails can damage shingles and underdriven nails can interfere with flatness and sealing. Air supply, hose configuration and temperature affect fastening. The goal is a correctly placed, flush nail, not simply a fixed compressor setting throughout the job.
A useful question for your contractor
Ask how the crew checks nail depth and corrects fasteners that are driven improperly.
Ask for the answer to be tied to the actual roof condition and the exact product being installed. Keep the agreed repair or installation detail with your estimate and project photos.
