Roofing Services in Potrero Hill, San Francisco
Honest, no-oversell roofing in Potrero Hill from a family-owned San Francisco contractor since 1996.
Potrero is a mix of original Victorian and Edwardian homes on the north slope, mid-century single-family on the south, and an increasing number of modern condo and live/work conversions with flat single-ply roofs and roof decks.
Potrero gets some of the best sun and least fog in the city. That's great for living but tough on dark torch-down membranes that bake all summer. Reflective TPO or a white coating dramatically extends roof life on south- and west-facing Potrero flats.
"If your Potrero flat roof is dark and over 12 years old, a reflective coating may add 8–10 years for a fraction of a re-roof. We'll tell you when that's the right call."

Local roof planning in Potrero Hill
A sunny Potrero flat roof needs attention around rooftop equipment as well as across the open membrane. Air-conditioning service, solar maintenance and roof-deck use can leave punctures or displaced protection pads. Look for a defined access route to equipment and inspect every curb where the membrane turns upward. Reflective coatings are an option only when the existing roof is dry, stable and compatible with the proposed coating system.
Converted industrial buildings near the foot of the hill and older houses higher on the slope have different drainage layouts. A large commercial field may require several outlets, while a small rear addition may depend on a single scupper. Ask the contractor to explain where overflow would go if the main drain became blocked. Roof-deck finishes should not hide inspection points or prevent maintenance of the waterproofing underneath.
Why choose Ace for your Potrero Hill 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.

Potrero Hill Roofing FAQs
Are reflective roof coatings worth it in Potrero Hill?
On dark torch-down or aged metal roofs with high sun exposure, yes — a properly applied coating system can extend roof life 8–10 years and reduce summer attic temperatures noticeably.
Can you install or repair a roof deck on Potrero?
Yes. Roof decks over occupied space need very careful waterproofing and drainage detailing — we do this work regularly on Potrero and SoMa conversions.
Do you offer warranties on Potrero re-roofs?
Every re-roof we do carries a written workmanship warranty in addition to the manufacturer's material warranty.
