Your Roof Doesn't Wait for a Convenient Time

A leaking roof doesn't send a calendar invite. It shows up as a dark stain on your ceiling at 11pm during a rainstorm. Or as mold in your attic that you didn't know about for two years. By the time you see the damage inside your home, the problem above it has been growing for months.

San Francisco's roofing challenges are unique. The fog belt delivers constant moisture. Victorian and Edwardian homes have steep pitches and complex rooflines that require skill and precision to work on safely. Tight lot lines mean limited staging and access. And California's Title 24 cool roof requirements mean not just any material will pass inspection.

Gadget Construction has been installing and repairing roofs across San Francisco for over a decade. We've worked on flat commercial roofs in SOMA and steep-pitch Victorians in Pacific Heights. We know which materials perform best in SF's microclimates, and we install them with the precision that steep, complex rooflines demand.

Frequently Asked Questions

A full re-roof for a typical San Francisco single-family home (1,200–1,800 sq ft of roof area) generally costs $15,000–$35,000 depending on material choice, roof complexity, number of layers to remove, and access conditions. Steep-pitch Victorian homes with complex rooflines cost more than simple ranch-style roofs. We provide itemized estimates after a free roof inspection.

Asphalt composition shingles: 20–30 years. Architectural shingles: 30–40 years. Metal roofing: 40–70 years. Tile: 50–100 years. SF's fog and moisture can shorten lifespan compared to drier climates, which is why material selection and proper ventilation matter here more than most places. We recommend materials suited specifically to your neighborhood's microclimate.

Signs you need a full replacement: your roof is 20+ years old, you see widespread curling or missing shingles, there are multiple active leaks, or daylight is visible from the attic. If the damage is isolated to a small area and the rest of the roof is in good shape, a targeted repair may be all you need. We'll give you an honest assessment — we don't upsell replacements when a repair will do.

California's Title 24 building energy code requires certain roof materials to meet solar reflectance and thermal emittance standards — essentially, the roof needs to reflect heat rather than absorb it. This applies to most re-roofing projects in SF. Non-compliant materials won't pass city inspection. We only install Title 24 compliant materials, so you won't have inspection issues.

Yes. A full re-roof in San Francisco requires a building permit from DBI. Repairs that don't exceed a certain scope may be exempt, but it's always safer to check. We handle all permit applications and inspection scheduling as part of every project.
