Valley and Step Flashing Leak Detection, explained.
A roof valley carries the runoff of two slopes. That concentrated flow, plus leaves and debris, makes valleys one of the hardest-working parts of a roof. When valley metal rusts, shingles wear or flashing steps loosen where a roof meets a wall or dormer, water gets under the roofing.
We examine valleys for debris, wear, exposed metal and shingle cuts, then follow walls, dormers, and roof-to-wall transitions looking at step flashing, kick-out flashing and sealant. We also look at gutters at valley ends where overflow can cause trouble. The report maps each suspect detail with photographs.

Why do valleys leak?
They carry more water than any other part of the roof and trap debris.
What is kick-out flashing?
A small flashing that directs water from a roof edge into the gutter instead of behind the siding.
Can leaves cause leaks?
Yes. Debris dams water and holds moisture against the roofing.
