01
Map where breaks occur
Record whether damage clusters near an access route, a roof junction, an edge, or a recently serviced feature. Note when it was first observed and whether there was nearby work. Photographs should show adjacent courses as well as the damaged piece. Similar-looking breaks can have different causes, so avoid diagnosing the roof from appearance alone.
02
Ask for a cause-based repair
Have the contractor examine the relationship between the affected pieces, surrounding details, and possible contact or installation issues. Ask whether replacement alone addresses the problem or whether the contributing condition also needs attention. Preserve the original photographs so later inspections can identify a recurring pattern. The value of the record is in comparing locations and events, not assigning blame without evidence.
