Roofing Services in SoMa, San Francisco

Honest, no-oversell roofing in SoMa from a family-owned San Francisco contractor since 1996.

SoMa is San Francisco's commercial flat-roof core — converted warehouses, mid-rise office buildings, live/work lofts, and an expanding inventory of modern condos. Almost everything here is flat or low-slope single-ply membrane, much of it concealing roof decks, HVAC equipment, or solar arrays.

SoMa is one of the warmest and sunniest parts of San Francisco. Combined with the heat-island effect from concrete and asphalt, dark flat roofs here run extremely hot in summer — a real factor in membrane lifespan and cooling costs.

"Half the SoMa flat-roof leak calls we get are HVAC contractor penetrations that were never flashed properly. We document what we find before we touch it."

We maintain several roof-deck buildings between 3rd and 5th Streets — solar arrays, HVAC, and deck traffic all sharing the same membrane.

Local roof planning in SoMa

SoMa roofs often function as service platforms for an entire building. Before maintenance, identify who has accessed the roof since the last inspection and whether equipment or cable supports were added. New penetrations, loose conduit and displaced walk pads can explain a sudden leak on an otherwise sound membrane. Keep a photographic roof log so a manager can distinguish an old condition from damage after a service visit.

For warehouse conversions and mixed-use properties, a roof proposal should explain tenant protection and equipment coordination. Drains cannot be treated as an afterthought on a broad low-slope field, especially where deck finishes obscure the surface. Ask how drain strainers, overflow points and membrane terminations remain accessible. A planned inspection route helps prevent routine HVAC work from becoming an unintentional roofing repair project.

Why choose Ace for your SoMa 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.

SoMa Roofing FAQs

What's the right flat roof for a SoMa commercial building?

We usually recommend white TPO single-ply for new SoMa commercial installs — high reflectivity, long warranty options, and clean detailing around HVAC and solar equipment.

Can you coordinate with our HVAC or solar contractor?

Yes — we work alongside HVAC and solar crews regularly on SoMa roofs and re-flash penetrations correctly after their work.

Do you handle commercial roof maintenance contracts?

We offer scheduled biannual maintenance for SoMa commercial buildings — drain clearing, seam inspection, and resealing — which materially extends single-ply membrane life.
