What do housing and permit records say about the Mission?
The Mission reroofs are steady business: DataSF lists 1,145 permits mentioning reroofing in the Mission planning area between 2016 and 2025 (DataSF), fourth among the city's 40 planning areas. By ZIP code, ZIP 94110: median home built 1939 or earlier, 42% of occupied homes owner-occupied, 19% detached houses (ACS 2024 5-year via Census Reporter).
What kinds of roofs are common in the Mission?
The Mission is mostly Victorian and Edwardian flats and row houses, many with a flat roof behind a front parapet or false front and a shared wall on each side. Most homes are rented, so many reroofs are building-owner or association decisions.
How does the Mission's weather wear on a roof?
The California Energy Commission puts the Mission in climate zone 3, the cool coastal zone (CEC climate zones). The nearest long-record NOAA station, downtown San Francisco, averages 22.9 inches a year on the 1991-2020 normals, with 59% arriving in December through February. It rarely gets hot: about 3 days a year reach 90 degrees, so moisture, not heat, is what ages roofs. (NOAA normals)
Do historic rules affect a Mission reroof?
Liberty Hill, between 20th, 22nd, Mission and Dolores streets, is a San Francisco Article 10 landmark district (SF Planning). Exterior changes there can need a Certificate of Appropriateness, and DBI routes historic reroofs to a review with a two-business-day goal (SF.gov). A flat roof hidden behind a parapet is usually simpler than a visible one, but ask first.
Do I need a permit to replace a roof in the Mission?
Every San Francisco reroof goes through the Department of Building Inspection. A licensed C-39 contractor can get a reroofing permit online on PermitSF for a non-historic home when no structural work is needed, and the street-space fee for a dumpster is included (SF.gov: reroofing permit). Rotten decking found mid-job means an over-the-counter building permit.

Do I need historic review to reroof in Liberty Hill?
Possibly. Liberty Hill is an Article 10 landmark district, and DBI sends historic reroofs to a short review. Visible changes in material or profile are the ones most likely to need Planning's approval.
Who issues reroof permits in the Mission?
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 Mission 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.
