Roof Leak Repair in San Carlos, California

The winter rain in San Carlos finds every gap the fog left behind. The flashing corrodes, the valleys wear, and the salt air eats the metal. Roof leak repair in San Carlos traces the water to its source and stops the leak for good.

Signs Your San Carlos Roof Has a Leak

• Water stains on the ceiling — the water has found a path through the roof
• Water stains on the walls — the water is running down the interior framing
• Damp or musty smells in the attic — the moisture is trapped in the insulation
• The paint is bubbling or peeling — the moisture is getting behind the interior finish
• Rust stains on the ceiling — the water is running over the corroded metal

Why San Carlos Roofs Leak

The winter rain is the main cause. The rain comes steady from November through April, and the water finds the gaps. The flashing at the chimney, the valleys, and the pipe boots is the common leak point.

The salt air and the fog create the gaps. The salt corrodes the flashing and the fog keeps the metal damp. The winter rain finds the corroded flashing and the worn seams.
