How old are homes in the Sunset and Parkside, and how often are roofs replaced?
Census figures by ZIP code give a picture of the housing (ZIP 94122: median home built 1942, 48% of occupied homes owner-occupied, 25% detached houses; ZIP 94116: median home built 1945, 73% of occupied homes owner-occupied, 37% detached houses; ACS 2024 5-year). City permit data adds the roofing side: 2,982 building permits issued from 2016 through 2025 in the Sunset/Parkside and Inner Sunset planning areas mention reroofing in their descriptions (DataSF), more than any other neighborhood in the city.
What kinds of roofs are common in the Sunset and Parkside?
Most Sunset and Parkside houses are 1920s to 1950s stucco row homes built tract by tract, many by developers such as Henry Doelger. The front is often a decorative parapet hiding a flat or low-slope roof behind it, with a light well or two. Those roofs need a membrane system, careful parapet flashing and working scuppers or drains, not shingles.
Does salt air affect Sunset roofs?
West of 19th Avenue, salt air and wind off Ocean Beach work on every piece of metal: drains, vent caps, nails and flashing. A Sunset bid should name corrosion-resistant fasteners and say how the roofer will re-flash the parapet, where most leaks start.
What is the Sunset and Parkside's climate like for a roof?
Title 24 assigns the Sunset and Parkside to climate zone 3, the cool coastal zone (CEC climate zones by ZIP). At the San Francisco Oceanside station, NOAA's 1991-2020 normals come to about 20.6 inches of rain a year; 59% of it falls in the three winter months. It rarely gets hot: about 1 days a year reach 90 degrees, so moisture, not heat, is what ages roofs. (NOAA normals)
Do I need a permit to replace a roof in the Sunset and Parkside?
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.
