01
Ask for all sides to be assessed
A photograph of the front apron cannot establish the condition behind the chimney. Request observations of the uphill junction, side intersections, and the relationship between flashing and masonry. Access limitations should be recorded. A leak near the chimney may also require assessment of masonry or other building components.
02
Use a complete scope
If only one side needs work, the proposal should explain how it connects to retained flashing. If a wider renewal is recommended, ask for the evidence and sequence. Coordinating roof and masonry work helps avoid closing an area before a necessary connection is resolved. Keep labeled photographs of each side with the repair record.
