Roof Leak Repair in San Marcos, California

The winter rain in San Marcos finds every gap the summer left behind. The flashing pulls away, the valleys wear, and the Santa Ana wind lifts the shingles. Roof leak repair in San Marcos traces the water to its source and stops the leak for good.

Signs Your San Marcos 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
• The shingles are stained or curling near the flashing — the flashing is failing

Why San Marcos Roofs Leak

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

The heat and the wind create the gaps. The summer sun dries out the sealant and the flashing, and the Santa Ana wind lifts the shingles. The winter rain finds the damage.
