Wind damage can reach beyond a missing shingle
Wind can lift a shingle edge before it tears away. The material still on the roof may have creases, damaged fastening points or a broken seal. Looking only at the missing pieces can understate the work needed to make the area sound again.
Edges, ridges and transitions deserve inspection along with the field of the roof. A displaced metal detail can admit water even when nearby shingles remain in place. The inspection should follow the affected area far enough to find a suitable tie-in, not assume that every slope needs the same treatment.
