How old are homes in Pacific Heights, and how often are roofs replaced?
Census figures by ZIP code give a picture of the housing (ZIP 94115: median home built 1949, 26% of occupied homes owner-occupied, 7% detached houses; ACS 2024 5-year). City permit data adds the roofing side: 931 building permits issued from 2016 through 2025 in the Pacific Heights and Presidio Heights planning areas mention reroofing in their descriptions (DataSF), 12th among the city's 40 planning areas.
What surprises turn up on older Pacific Heights roofs?
Slate and tile can't be overlaid under California's code, and both are often repaired or reset rather than replaced. Ask for a roofer who will tell you honestly whether a slate roof needs replacement or just repair.
What is Pacific Heights's climate like for a roof?
Title 24 assigns Pacific Heights to climate zone 3, the cool coastal zone (CEC climate zones by ZIP). NOAA's 1991-2020 normals for the downtown San Francisco station show about 22.9 inches of precipitation a year, 59% of it in December, January and February. It rarely gets hot: about 3 days a year reach 90 degrees, so moisture, not heat, is what ages roofs. (NOAA normals)
What kinds of roofs are common in Pacific Heights?
Pacific Heights has some of the city's largest Victorian, Edwardian and early-20th-century houses, with steep rooflines, towers, dormers and, on some, slate or tile. Many sit on steep blocks, so staging and protecting ornate exteriors are a big part of the job.
Do historic rules affect a Pacific Heights reroof?
The Webster Street historic district lies within the neighborhood, and other Article 10 landmark districts and individual landmarks are scattered nearby (SF Planning). DBI routes reroofs on historic buildings to a review with a two-business-day goal (SF.gov), and visible material changes can need Planning approval.

Can I replace a slate roof in Pacific Heights with something lighter?
Sometimes, but check historic status first. On a landmark or in a landmark district, a visible material change can need Planning approval.
Who issues reroof permits in Pacific Heights?
San Francisco's Department of Building Inspection. Licensed C-39 contractors can apply online for a reroofing permit when no structural work is needed.
Can I get a firm price for a Pacific Heights roof without an inspection?
No. A roofer needs to measure the roof, count layers, check the pitch and look at the deck from the attic before a price is firm.
