Roof leak repair in San Rafael starts inside the house. Water often enters at one spot, runs along the roof deck or a rafter, and drips somewhere else. The roofer checks the attic first, then the roof above it, to find the real entry point before patching anything.
On pitched roofs, the usual leak points are flashing at chimneys and walls, rubber boots around vent pipes, skylight frames and roof valleys. Valleys under oaks and bay laurels in Sun Valley, Terra Linda and Lucas Valley fill with leaves, and water backs up under the shingles in a heavy storm.
On flat Eichler roofs, leaks start at clogged drains, open seams, blistered membrane and old patches. Water can pond for days after a storm, so a small gap leaks far more than it would on a sloped roof.
A single leak on a sound roof is a repair. Leaks in several places, or a roof that has been patched many times, point to replacement. Larger repairs inside city limits may need a permit from the City of San Rafael Building Division.
Technician insight
A leak that shows up only in strong wind-driven rain usually comes from flashing or lifted shingle edges. A leak that shows up in any rain is more often a hole, a cracked boot or a failed seam.
