Signs Your Valleys Are Failing
Interior stains where two roof planes meet above, granule piles at the bottom of a valley, visible rust or holes in open valley metal, and shingles lifting along the valley line all point to valley failure.
From inside the attic, look for water staining on the underside of the decking along the valley line — that's the smoking gun. Moss growth is aggressive here — it lifts shingles and holds moisture against the roof surface.

Open vs. Closed Valleys: What We Recommend
Open valleys — with exposed metal — shed debris better and make future inspection easy; they're our default recommendation in debris-prone areas. Closed valleys look cleaner but hide problems until the leak appears inside.
For Hazel Valley homes with surrounding trees, open metal valleys are almost always the better long-term choice. Its low-slope ranch rooflines have long valleys that collect fir needles year-round. We discuss both options and price both.

Roof Valley Leak Repair in Hazel Valley FAQs
How long will the repaired valley last?
A properly rebuilt valley with new metal and membrane lasts as long as the surrounding roof — 20+ years — and is water-tested and warranted.
Can you repair just one valley?
Yes — valleys are repaired individually. If other valleys show early wear, we'll point it out and price them, but there's no obligation to do them all at once.
Do clogged valleys cause leaks even if the metal is fine?
Absolutely — debris dams force water sideways under perfectly good shingles. Hazel Valley is a quiet residential neighborhood of mid-century ranches in central Burien. Regular clearing prevents most of these leaks.
