Roofing Services in Mission District, San Francisco
Honest, no-oversell roofing in Mission District from a family-owned San Francisco contractor since 1996.
The Mission is a dense mix of Victorian and Edwardian flats, mid-block stucco apartment buildings, and flat-roof commercial storefronts along Mission, Valencia, and 24th. Most residential properties here run wood-frame with low-slope or true flat roofs hidden behind a parapet, often with original cap-sheet or modified bitumen long past its service life.
The Mission sits in one of the warmest, sunniest microclimates in San Francisco — far less fog than the western neighborhoods, but more thermal cycling on dark flat-roof membranes. That heat-then-cool stress is what shortens torch-down lifespans east of Twin Peaks.
"We see a lot of Mission flat roofs where a $400 drainage and seam repair will buy another decade — and we'll tell you that before we ever quote a full tear-off."

Recent local project
We recently replaced a full modified-bitumen roof on a mixed-use building near 24th and Folsom, keeping the ground-floor taqueria open the entire two-week job.
Local roof planning in Mission District
On a narrow Mission block, a roof may serve several apartments and a street-level business at once. Before opening the surface, identify which drains serve each section and whether a rear addition has a separate outlet. Water that backs up above one unit can travel into another through shared framing. A repair plan should show the path from the highest roof section to the final downspout, rather than treating the stain below as the whole problem.
Sunny Valencia-facing roofs and shaded rear light wells can age differently even on the same building. Inspect exposed membrane laps for movement, but also examine damp corners where debris settles behind parapets. When comparing replacement proposals, ask how rooftop vents, kitchen exhausts, neighboring walls and access through occupied flats will be protected. Those details distinguish a practical Mission project from a generic material quote.
Why choose Ace for your Mission District roof?
Our family-owned company has served San Francisco and the Bay Area since 1996. We are licensed, bonded and insured, and begin with the condition of your existing roof rather than assuming replacement is necessary. Explain when a leak appears, share earlier repair records and tell us about access restrictions. That information helps distinguish a localized flashing or drainage problem from wider material deterioration. A useful recommendation identifies the defect, the work needed to correct it and any limitations of repairing the surrounding older roof.
For a replacement, compare written scopes rather than headline prices. Ask what happens to old roofing layers, how exposed decking is checked, which materials and flashings are included, and how permit requirements will be confirmed. Discuss daily weather protection, cleanup, warranty terms and approval of hidden damage before work begins. Once the project is complete, keep your photographs and paperwork together and agree on sensible drain and flashing checks. Continued maintenance is part of protecting the investment, whether the work was a small repair or a complete new roof.

Mission District Roofing FAQs
How much does a flat roof repair cost in the Mission District?
Targeted flat-roof repairs in the Mission typically run $400–$1,800 depending on access, the size of the failed area, and whether drainage work is also needed. We give a written quote after a free on-roof inspection — no pressure to take it.
Do you re-roof Victorian flats in the Mission?
Yes. We re-roof Mission Victorians and Edwardians regularly, usually a combination of new modified bitumen or TPO on the flat sections and composition shingles on any visible front-facing slopes.

We do. We work on storefront and small commercial flat roofs across the Mission corridor — including coordinating around tenants and after-hours work when needed.
