Roof Flashing Repair in Southern Heights, 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 Southern Heights, Burien, WA. Its postwar housing stock has original flashing and first-replacement roofs both aging out.
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. Proximity to the Normandy Park slopes means some streets catch extra runoff in heavy rain.
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 postwar housing stock has original flashing and first-replacement roofs both aging out. Every repair is water-tested before we leave.
- Sealed and fastened to manufacturer spec
- Water testing before sign-off
- Failed flashing fully removed, not patched over
- Decking and underlayment inspected beneath
Why Southern Heights Roofs Punish Weak Flashing

We also see plenty of original builder-grade flashing on Southern Heights homes — thin galvanized metal installed to a price point, now at the end of its service life. Its postwar housing stock has original flashing and first-replacement roofs both aging out.
- Dissimilar-metal corrosion at mixed details
- Accelerated corrosion from local exposure
- Builder-grade flashing at end of life
- Sealant joints worked loose by thermal cycling
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.

Roof Flashing Repair in Southern Heights FAQs
Is flashing repair covered by insurance?
Wear-and-tear flashing failure usually isn't, but storm-damaged flashing often is. Our photo documentation helps your adjuster see the difference.
Do you match the existing flashing material?
We match or upgrade the metal to suit your roof and local exposure — and we never mix dissimilar metals in contact, which causes galvanic corrosion.
My roof is only a few years old — why is the flashing already failing?
The most common cause is reused old flashing during a re-roof, or builder-grade thin metal. Its postwar housing stock has original flashing and first-replacement roofs both aging out. We see this often in Southern Heights and replace it with proper new material.
