Roof Repair in Walnut Creek, CA

Most roofs here fail at the details, not the field of shingles. Sun bakes the asphalt until granules loosen, then wind gets under a lifted shingle and water wicks into the underlayment. We find the source with a full roof inspection before we quote.

Repairs on mid-century modern homes from the 1950s and 1960s often mean matching a three-tab shingle nobody stocks anymore. Contemporary homes built in the 1990s and 2000s usually take an architectural shingle or a metal panel.

Spanish and Mediterranean revival style homes need the tile and clay tile lifted, the underlayment renewed, and each piece reset on new battens and counterbattens. Wood shake and cedar shake get individual replacement instead, and slate or concrete tile follows the same reset routine.

Flat and low-slope sections take a different fix. We patch a TPO or PVC membrane with reinforcing fabric and a repair coat, and reseam EPDM before it dries out.

A modified bitumen or built-up roof gets a recoat while the tar and bitumen still have life. Metal panel and corrugated panel sections get checked at the purlins, since exposed fasteners loosen first.

A dormer, parapet, or mansard roofline gives water more places to sit. On a steep hip or gable we check the verge and overhang, and a gambrel or canopy awning over an entry gets the same look.

Scuppers and coping on flat sections clog with debris and hold water against the membrane. That ponding works under the seams, so we clear them and check the seams while we're up there.

Under the roof we check the truss and rafter bays, the ridge beam, and the joists for sag or rot. Missing insulation and a dead attic fan let heat build until the roof deck cooks from below.
