What kinds of roofs are common in Noe Valley?
Noe Valley is Victorian and Edwardian San Francisco: houses and flats built mostly before 1940, many with a steep front gable or false front, a flat or low-slope section behind, bay windows and decorative cornices. A reroof often means two systems on one house, shingles in front and a membrane behind, with tricky flashing where they meet.
How does Noe Valley's weather wear on a roof?
Noe Valley sits east of Twin Peaks, which blocks much of the fog that covers the west side, so roofs here dry out faster than in the Sunset. Sun-facing slopes see more UV wear, and the hill streets on the slopes toward Diamond Heights add staging work.
How does Noe Valley's weather wear on a roof?
The California Energy Commission puts Noe Valley in climate zone 3, the cool coastal zone (CEC climate zones). At the downtown San Francisco station, NOAA's 1991-2020 normals come to about 22.9 inches of rain a year; 59% of it falls in the three winter months. It rarely gets hot: about 3 days a year reach 90 degrees, so moisture, not heat, is what ages roofs. (NOAA normals)

Why does a Noe Valley roof often need two kinds of roofing?
Many Victorians and Edwardians have a steep front section and a flat section behind it. The steep part takes shingles; the flat part needs a membrane.
Who issues reroof permits in Noe Valley?
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 Noe Valley 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.
