Roofing Before & After in San Francisco, CA

Photos don’t need a sales pitch. They show the sagging deck, the patched valley, the moss line at the eave, and then they show the same roofline after our crew packs up and leaves. The difference is why people call Birchbark Roofing San Francisco. Here are a few recent transformations from neighborhoods across the city, from the Sunset to Portola.

Recent Transformations

Complete Tear-Off and Replacement on a 1920s Inner Richmond Home

BeforeAfter

The house had its original skip sheathing plus two layers of shingles added in the 70s and 90s. When the fog rolled in, the deck stayed damp. We tore everything to the rafters, replaced rotted sheathing boards, and laid fresh underlayment before installing a full CertainTeed Landmark system. The homeowner told us the upstairs bedroom finally holds heat in July.

Leaking Valley Repair Near Mount Davidson

BeforeAfter

A valley collects more water than any other part of a roof, and this one had been collecting it into the attic. The old metal was rusted through in three spots, and the shingle cuts were too tight to shed debris. We pulled the valley, laid ice-and-water shield wall to wall, and rebuilt it with a proper open metal channel. Dry attic, first rain after the job.

Flat Roof Re-Cover in the Sunset District

BeforeAfter

Flat roofs in the Sunset take wind-driven rain straight off the ocean. This one had cracked at every seam and puddled in the center, which is exactly what we found on the interior ceiling below. We stripped the old cap sheet, addressed the low spot with a tapered system, and welded a new GAF TPO membrane. The puddles drain now instead of sitting for days.

Chimney Flashing Replacement in Bernal Heights

Bernal Heights homes sit on a hill that catches every weather system moving through the city. The chimney here leaked at the uphill corner, where step flashing had pulled away from the brick. We cut the old counter-flashing out of the mortar joints, installed new step flashing course by course, and sealed the crown. No more brown stain on the living room ceiling.

Moss and Debris Remediation on a Stanyan Street Garage Roof

Moss grows fast in the permanent damp of the Panhandle side streets. On this garage roof, it had wedged under the shingle tabs and lifted them enough to catch wind. We removed the growth carefully so we didn’t tear the granule surface, replaced the damaged tabs, and re-secured the edge metal. It’s maintenance, not replacement, and done right it buys years.
