When installing composition shingle roofing in California seismic zones, what additional fastening requirement applies compared to standard installation?
Correct Answer
A) Use 6 nails per shingle instead of 4 in high seismic areas
California Building Code Section 1507.2.8.1 requires 6 fasteners per shingle in areas subject to high winds or seismic activity, compared to the standard 4 fasteners. This enhanced fastening pattern provides additional resistance to uplift forces during seismic events common in California.
