Chimney & Flashing Repair in Rohnert Park, California

The chimney is the most common roof leak in the North Bay. The flashing seals the gap between the chimney and the roof, and the winter rain finds every gap. Chimney and flashing repair in Rohnert Park fixes the leaks and protects the chimney.

Signs Your Rohnert Park Chimney Flashing Needs Repair

• The water stains on the ceiling near the chimney — the flashing is leaking and the water is running down the chimney
• The mortar is crumbling on the chimney — the water is getting behind the flashing and the freeze-thaw cycle is damaging the mortar
• The rust or the corrosion on the flashing — the old galvanized metal is failing in the damp
• The sealant is cracked or missing — the tar or the caulk at the flashing joint is failing
• The chimney is leaning or the brick is spalling — the water damage is structural

Why Rohnert Park Chimneys Need Flashing Repairs

The chimney is the roof penetration that takes the most weather. The damp air corrodes the flashing and the winter rain tests the joints. The moss grows on the flashing and traps the moisture.

The step flashing is the key. Each piece of flashing steps up the side of the chimney and the counter flashing covers the top edge. If the step flashing is corroded or the counter flashing is loose, the water runs behind the flashing and into the house.

Preventing Roof Problems in Rohnert Park

• Check the chimney flashing each spring — the winter rain reveals the leaks

• Check the moss on the chimney — the moss traps the moisture against the flashing
• Check the cricket — the cricket diverts the water around the chimney

Expert tip: in Rohnert Park, the chimney flashing is the most common roof leak. The step flashing needs to be woven into the shingles, not just caulked on the surface. The caulk fails and the water runs behind the flashing.
