Chimney Flashing Repair in the Pittsburgh Area

What chimney flashing repair involves

Flashing is the metal that seals the joint where the chimney passes through the roof. Flashing repair reseals and secures that metal — and the caulk and sealant around it — so water runs off the roof instead of down alongside the chimney.

Why homeowners need it

The chimney-to-roof joint is one of the most common places for a house to leak, because it's where two different surfaces meet and move. When the flashing lifts, corrodes or its sealant fails, water follows the chimney down into the roof structure. Repairing it is often the fix for a leak people assumed was the chimney itself.

Common problems it addresses

• Lifted or loose flashing
• Failed caulk and sealant at the flashing
• Corroded or damaged flashing metal
• Water entering at the roof-to-chimney joint

Warning signs to watch for

• Water stains on the ceiling near the chimney
• Visible gaps or lifted metal at the roofline
• Dried, cracked caulk around the flashing
• Leaks that appear during or after rain

How we approach the work

What this means for Pittsburgh-area homes

Flashing leaks are extremely common in the Pittsburgh area, and freeze-thaw is again the reason — repeated freezing lifts and works the metal and cracks old sealant. It's one of the first things we check when a homeowner reports a stain near the chimney.
