Chimney & Flashing Repair in San Clemente, California

The chimney is the most common roof leak on the coast. The flashing seals the gap between the chimney and the roof, and the winter rain finds every gap. Chimney and flashing repair in San Clemente fixes the leaks and protects the chimney.

Signs Your San Clemente 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 salt air is corroding the metal
• 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 San Clemente Chimneys Need Flashing Repairs

The chimney is the roof penetration that takes the most weather. The salt air corrodes the flashing and the winter rain tests the joints. The coastal damp keeps the metal moist and accelerates the corrosion.

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 San Clemente

• Check the chimney flashing each spring — the winter rain reveals the leaks
• Check the mortar each year — the crumbling mortar means the water is getting in
• Check the flashing for the corrosion — the salt air eats the metal
• Check the cricket — the cricket diverts the water around the chimney

Expert tip: in San Clemente, 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.
