Questions about leak inspection.
Why is the roof leak not directly above the ceiling stain?+
Water can travel along decking, framing, insulation, pipes, or other surfaces before becoming visible indoors.
Can a roof leak inspection find plumbing leaks?+
It may identify signs suggesting a non-roof source, but plumbing diagnosis may require another qualified trade.
Can leaks be inspected when it is not raining?+
Yes. Staining, moisture paths, damaged materials, flashing failures, and prior repairs may still provide useful clues.
Should interior repairs happen before the roof repair?+
Usually the water source should be corrected first so repaired interior finishes are not damaged again.
