Asphalt shingles are blowing off in high winds shortly after installation. The MOST likely installation error is:
a.Too many nails per shingle
b.Nails driven too deep is impossible
c.Using the correct nail placement
d.Nails placed too high above the nailing strip or overdriven/underdriven, so they miss the shingle above
Giải thích
Fasteners placed above the designated nailing zone, or overdriven/underdriven, fail to secure both the shingle and the tab of the course above, causing wind blow-off. Using the correct placement would not cause failure, and too many nails is not the typical cause of blow-off.
