Roof Leak Repair in Montclair, California
The ceiling stain is the first sign, and it usually means water has been working through the roof for a while. Roof leak repair in Montclair means finding the source, not just patching the stain. In the Inland Empire, the leak often starts at a shingle the summer heat cracked months before the rain.
Common Leak Sources in Montclair
- Cracked and brittle shingles
- Lifted flashing at the valleys and the penetrations
- Failed seals around the vents and the pipes
- Damaged or clogged gutters
- Santa Ana wind damage to the flashing
Why Montclair Roofs Leak
The summer heat dries out the shingles and the sealant. The asphalt shrinks and cracks, and the sealant around the vents pulls away from the metal. The winter rain then finds the cracks. The Santa Ana wind pushes the rain into the flashing.
