Chimney Flashing Repair in Batavia, NY
Chimneys interrupt the roof’s drainage plane and require carefully integrated flashing. Leaks can develop at step flashing, counterflashing, the upslope cricket or saddle, corners, sealant joints, surrounding shingles, or damaged decking. The repair should address the water path—not simply cover the area with roof cement.

How Chimney Flashing Works
Step flashing directs water from the roof-to-chimney sidewall. Counterflashing protects the upper edge. Apron flashing handles the downslope side, while a cricket or saddle may help divide water on the upslope side of a wider chimney.
Signs of a Flashing Problem
Interior stains near the chimney, damp framing, loose or rusted metal, cracked sealant, lifted shingles, debris buildup, and repeated patching can indicate a problem. Masonry caps and joints may also contribute and should not be confused with roof flashing.
A Durable Repair Scope
A proper scope may require removing surrounding shingles, evaluating decking, installing compatible underlayment and metal flashing, integrating counterflashing, and replacing shingles. Conditions and access determine the work.
Frequently Asked Questions
Is sealant alone a permanent chimney repair?
Usually not when the flashing assembly has failed. Sealant can be a maintenance component, but it should not replace correctly integrated flashing.
Can chimney masonry cause roof leaks?
Yes. Caps, crowns, mortar joints, and porous masonry can contribute, so the water source must be evaluated carefully.
Can flashing be repaired without replacing the whole roof?
Often, when the surrounding roofing remains serviceable and compatible materials are available.
