Chimney Flashing Repair
The seam where the chimney meets the roof is a top source of leaks. Proper flashing keeps that joint watertight.
Flashing is the metal that seals the joint where your chimney passes through the roof. It's one of the most common sources of chimney leaks, because that seam is constantly exposed to runoff and any failure — corroded metal, failed sealant, or a poor original installation — sends water straight into the roof and ceiling below.
Frank & Sons repairs and replaces chimney flashing throughout the Pittsburgh area. Because a leak at the flashing often gets blamed on the chimney itself (or vice versa), diagnosing correctly matters — and flashing is one of the first places we look when a chimney leaks.
Signs of flashing failure
- Water stains on the ceiling near the chimney.
- Rusted, lifted, or visibly damaged metal at the roofline.
- Cracked or peeling tar/sealant around the chimney base.
- Leaks that appear during or right after rain.
- Daylight or gaps visible where chimney meets roof.
How we repair flashing
We assess whether the existing flashing can be resealed and repaired or whether it needs full replacement. Old tar patches and failed sealant are common quick-fixes that don't last; proper flashing uses layered metal (base and counter flashing) integrated into both the roof and the masonry to shed water reliably.
Where flashing has failed at the masonry joint, we cut it properly into the mortar and seal it so water can't get behind it. The result is a roof-to-chimney seam that stays watertight through storms and winters alike.
Why it matters in Greater Pittsburgh
Wind-driven rain and heavy snow loads test flashing hard in Western Pennsylvania. Snow that piles against a chimney and melts slowly finds any weakness in the flashing — which is why flashing failures are a leading cause of the winter chimney leaks we're called to fix.

Frequently Asked Questions
It sits at the intersection of both, which is why it's often misdiagnosed. As chimney specialists we address the flashing-to-masonry seal correctly, integrating it into the mortar rather than relying on surface tar.
Tar and caulk are temporary surface fixes that crack and peel with sun and temperature swings. Properly integrated metal flashing is the lasting solution.
Very possibly — flashing is one of the four main leak sources we check. Our leak diagnosis identifies exactly where water is entering.
