Roof Flashing Repair in Hazel Valley, Burien, WA

Flashing is the thin metal that keeps water out at every roof joint — and it's the #1 source of leaks we repair. Roof Leak Repair Specialists is the local licensed expert for roof flashing repair in Hazel Valley, Burien, WA. Its low-slope ranch rooflines have long valleys that collect fir needles year-round.

Roof flashing repair restores the metal transitions where your roof meets walls, chimneys, vents, and valleys. We remove the failed flashing, inspect the underlayment beneath, install new corrosion-resistant flashing, and seal it to manufacturer spec — then water-test the detail. Moss growth is aggressive here — it lifts shingles and holds moisture against the roof surface.

Our Flashing Repair Process

We never caulk over failed flashing and call it repaired. The old flashing comes out, the underlayment and decking beneath get inspected and repaired if rotted, and new flashing goes in with proper overlaps and fastening.

We use corrosion-resistant metals matched to your roof and climate — aluminum or galvanized steel for most homes, copper where longevity justifies it. Its low-slope ranch rooflines have long valleys that collect fir needles year-round. Every repair is water-tested before we leave.

• Corrosion-resistant replacement metals
• Sealed and fastened to manufacturer spec
• Water testing before sign-off
• Failed flashing fully removed, not patched over

Signs Your Flashing Is Failing

Rust streaks running down from a chimney or wall, water stains on interior walls near roof intersections, and visible gaps where metal meets masonry are the classic tells. From the ground with binoculars you can often spot lifted or missing sections.
