Roof Flashing Repair in Los Gatos, Campbell, CA
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 Masters is the local licensed expert for roof flashing repair in Los Gatos, Campbell, CA. Los Gatos is the affluent adjacent town with a historic downtown and 1920s–50s homes plus hillside estates.
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. Older homes here often feature clay tile or wood shake with aging underlayment.
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. Older homes here often feature clay tile or wood shake with aging underlayment. Every repair is water-tested before we leave.
- Water testing before sign-off
- Failed flashing fully removed, not patched over
- Decking and underlayment inspected beneath
- Corrosion-resistant replacement metals
Why Los Gatos Roofs Punish Weak Flashing
Los Gatos is the affluent adjacent town with a historic downtown and 1920s–50s homes plus hillside estates. That exposure accelerates corrosion and works sealant joints loose faster than inland roofs see. Homes here need flashing details built for the local weather, not the minimum code detail.
We also see plenty of original builder-grade flashing on Los Gatos homes — thin galvanized metal installed to a price point, now at the end of its service life. Older homes here often feature clay tile or wood shake with aging underlayment.
- Accelerated corrosion from local exposure
- Builder-grade flashing at end of life
- Sealant joints worked loose by thermal cycling
- Wind-driven rain exploiting small gaps
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.
Inside, flashing leaks show as stains at the top of walls or around chimney breasts — not in the middle of ceilings. Los Gatos is the affluent adjacent town with a historic downtown and 1920s–50s homes plus hillside estates. If that matches what you're seeing, flashing is the prime suspect.
- Stains at tops of interior walls
- Visible gaps at metal-to-masonry joints
- Loose or missing flashing sections
- Stains around the chimney breast

Yes. Tile, metal, and shingle roofs all rely on flashing at transitions — the details differ, but the principle and our process are the same.
How long does new flashing last?
