Roofing Services in Excelsior, San Francisco
Honest, no-oversell roofing in Excelsior from a family-owned San Francisco contractor since 1996.
The Excelsior is mid-century single-family San Francisco — small attached stucco homes from the 1930s–50s, mostly low-slope cap-sheet or modified bitumen roofs behind shallow parapets, with some pitched composition shingle on corner properties.
Excelsior sits in a sunnier southeast pocket — less fog than the Sunset, decent sun exposure, and meaningful wind out of the Daly City gap. Wind-driven rain is the most common leak trigger out here.
"Excelsior homes don't need premium materials to last — they need careful flashing and good drainage. We focus on those and don't upsell."

Recent local project
We re-roofed a full row of four attached homes on Naples Street last year, doing all four back-to-back to save each owner on setup and materials.
Local roof planning in Excelsior
An Excelsior rowhouse may have a main low-slope roof and a smaller roof above a garage or rear addition. Inspect each outlet separately: clearing the main drain will not solve ponding on an isolated lower section. Wind-driven rain can enter through a parapet cap or wall joint while the membrane below remains intact. Record whether stains appear after every rain or only storms from a particular direction.
Post-war roof layouts are often straightforward, but later skylights and utility penetrations add vulnerable details. Ask whether a repair will rebuild the flashing around those additions or simply cover an old sealant patch. On attached Naples and surrounding blocks, debris containment and safe ladder positioning should be agreed in advance. A modest roof does not need an elaborate sales pitch; it needs a clearly identified defect and a complete repair scope.
Why choose Ace for your Excelsior 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.
