Every project in San Francisco follows our proprietary 3-checkpoint quality system: checkpoint one after tear-off and deck inspection, checkpoint two during material installation at the midpoint, and checkpoint three at final completion with photo documentation. This process catches potential issues at every stage and ensures your finished roof meets our exacting standards. We provide a detailed completion report with before, during, and after photos for every project.
San Francisco roofs are unlike roofs anywhere else in California: steep Victorian and Edwardian pitches stacked wall-to-wall, flat tar-and-gravel rowhouse roofs in the avenues, and everything coated daily in ocean fog. Our headquarters is at 58 West Portal Avenue, so our crews live with the same salt air and microclimates your roof does.
In the Sunset and Richmond, most homes are 1930s-50s Doelger-era rowhouses with low-slope roofs originally built as tar and gravel. We replace these daily with modified bitumen torch-down or TPO, adding tapered insulation where decades of ponding have flattened the drainage. In Noe Valley, the Mission, Bernal Heights, and the Haight, we work on true Victorians and Edwardians — steep pitches, box gutters, decorative ridge details, and 100-year-old plank decking that usually needs partial replacement once the old layers come off.
Fog and salt air are the city's real roof killers: they corrode exposed fasteners and flashing years before the shingles themselves fail, and north-facing slopes grow moss that holds moisture against the roof. That is why our San Francisco installs use corrosion-resistant flashing details, algae-resistant shingle lines, and upgraded edge metal on homes west of Twin Peaks.

San Francisco's famous fog, wind, and cool maritime climate create unique roofing challenges. The city's predominance of flat-roofed row houses requires specialized flat roofing expertise, while Victorian and Edwardian homes demand preservation-sensitive materials and installation techniques. The average annual rainfall in San Francisco is 20–25 inches, with temperatures typically ranging from 45°F–68°F. Heavy fog exposure is a major factor affecting roof materials here. Wind exposure is high, and salt air from the bay or ocean accelerates corrosion on metal components.
Based on San Francisco's specific climate conditions at 52 ft elevation, these materials perform best:
Roof replacement costs in San Francisco typically range from $8,000 to $25,000 for residential properties, depending on roof size (measured in roofing squares — each square equals 100 square feet), material choice, roof pitch and complexity, number of layers to remove, and the condition of the underlying deck sheathing. Asphalt shingle replacement averages $350-$550 per square installed. Concrete tile runs $600-$900 per square. Standing seam metal is $800-$1,400 per square. Flat roof systems (TPO, modified bitumen) average $400-$700 per square. These prices include materials, labor, permits, debris removal, and manufacturer warranty registration. ROOF EXPRESS provides free, detailed written estimates with transparent line-item pricing — no hidden fees or surprise charges. Financing available up to $25,000 through Wisetack with $0 down.
Roof repair costs in San Francisco vary based on the scope of work. Simple repairs like replacing a few missing shingles or re-sealing a pipe boot typically cost $250-$750. Moderate repairs involving flashing replacement, valley repair, or localized leak fixes range from $750-$2,500. Major repairs including large sections of shingle replacement, deck repairs, or chimney flashing rebuilds can range from $2,500-$5,000. Emergency tarping for active leaks is available 24/7. We provide honest assessments of whether repair or replacement is the most cost-effective option for your situation.
San Francisco reroofing permits go through the Department of Building Inspection (DBI). Like-for-like reroofs are typically issued over the counter, but homes in historic districts or with visible street-facing slopes can require additional review, and low-slope roofs must meet California Title 24 cool-roof reflectance values. We prepare DBI paperwork, schedule inspections, and handle the final sign-off for every San Francisco project.
Proper roof maintenance extends your roof's lifespan by years and prevents costly emergency repairs. For San Francisco homeowners, we recommend these seasonal practices: In fall, clean all gutters and downspouts before the rainy season, trim tree branches hanging within 6 feet of your roof, and inspect for damaged or missing shingles. In winter, check for leaks after every major storm and ensure downspouts are directing water away from your foundation. In spring, schedule a professional inspection to assess winter damage and address any issues before summer heat. In summer, check attic ventilation to prevent heat buildup that degrades shingles from below, and look for signs of moss or algae growth in shaded areas. ROOF EXPRESS offers professional roof inspections with detailed photo reports.
Knowing when to replace your roof saves you from escalating repair costs and potential interior damage. Key indicators that San Francisco homeowners should watch for include: shingles that are curling, cracking, or losing granules (the sandpaper-like coating that protects the asphalt); daylight visible through the roof deck in your attic; sagging areas on the roof surface indicating structural deck damage; persistent leaks even after repairs; a roof age exceeding 20-25 years for asphalt shingles; dark streaks or moss growth covering large areas; and neighbors with similar-age homes already replacing their roofs. If you notice any of these signs, contact ROOF EXPRESS at (650) 666-5554 for a free inspection. We will give you an honest assessment of your roof's condition and remaining useful life.
