Roof Leak Repair in Covina, California

The winter rain comes hard in the San Gabriel Valley, and the aging roofs of Covina are the most at risk. Roof leak repair in Covina means finding the entry point and stopping the leak before the rot spreads.

Signs Your Covina Roof Has a Leak

• Water stains on the ceiling — the leak found its way through
• Dripping water in the rain — the active leak is showing
• A musty smell in the attic — the moisture is trapped in the insulation
• Mold or mildew on the attic deck — the moisture has been there for a while
• The paint is peeling on the ceiling — the water is trapped behind the surface

Why Covina Roofs Leak

The age of the roofs is the main cause. The 1950s-80s roofs have failed flashings and dried-out sealants, and the gaps are waiting for the water. The winter rain finds them.

The flashing is the second cause. The metal around the chimney and the vents works loose over time, and the gaps appear. The first hard rain then finds the gaps.
