Chimney Flashing Repair
Re-flashing and sealing where the chimney meets the roof — the most common source of chimney leaks.
Flashing is the metal that seals the joint where your chimney passes through the roof. When it lifts, corrodes or was installed poorly, water runs straight into the attic and down the walls. Most 'chimney leaks' are actually flashing leaks — and we fix them the right way, not with a bead of caulk.
Signs you need chimney flashing repair
- Water stains on the ceiling or wall around the chimney
- Dripping or dampness in the attic near the chimney
- Flashing is lifted, rusted or pulling away
- Previous caulk-only repairs keep failing
- Shingles near the chimney are curling or stained
The benefits
- Stops leaks at the true source
- Protects framing, insulation and drywall
- Proper metal-and-membrane seal, not a caulk band-aid
- Prevents mold and rot from spreading
- Blends cleanly with your roofline

Our process
Find the entry point
We trace the leak to confirm it's flashing and not crown or masonry.
Remove failed flashing
Old, lifted or corroded flashing and sealant are stripped out.
Re-flash properly
New step and counter-flashing are woven into the roof and locked into the masonry.
Seal & test
Joints are sealed and the area is water-tested to confirm the fix.

We handle chimney flashing repair for both homeowners and commercial properties — single-family homes, apartments, HOAs and businesses across the Front Range. Whatever the setting, you get the same careful, code-compliant work and honest pricing.
