Roofing Contractor in Sebastopol, CA

Rea Roofing Inc. works throughout Sebastopol and out through the surrounding country — the older homes in town, the ranch and orchard properties on the roads out toward Occidental and Graton, and the barns and outbuildings that come with them.

Moss is the defining Sebastopol roofing problem. Shaded, damp roof surfaces grow it readily, and moss is not merely cosmetic — it lifts the edges of composition shingles, holds water against the surface long after the rain stops, and works its way under tile and shake. On a north-facing slope under a redwood, moss will shorten a roof's life by years if it is left to establish.

Debris is the companion problem. Needles and leaves pack valleys and gutters through the fall, and a packed valley does not shed water — it backs it up under the covering and pushes it sideways into the structure. A great many west county leaks come down to drainage that was blocked rather than roofing that failed, which is a much cheaper thing to discover.

The practical consequence is that material choice and maintenance matter more here than almost anywhere else in the North Bay. Metal sheds debris far better than a textured composition surface and gives moss much less to hold onto, which is a real argument for it on a heavily shaded west county property — and gutters sized for genuine west county rainfall are not optional.
