Composition shingle, concrete tile, standing-seam metal, and low-slope flat assemblies — installed to the manufacturer's spec, not improvised on the roof.
Every roofing system has a right way to go on a South San Francisco roof and a dozen wrong ones. Composition shingle, concrete and clay tile, standing-seam metal, and TPO/EPDM flat assemblies each need a specific substrate, fastener pattern, and ventilation profile to actually earn the manufacturer warranty. We install the system you choose the way the spec — not the shortcut — requires, which is the difference between a roof that hits its rated life and one that fails early.
On South San Francisco roofs the conditions that matter most — Strong bay winds are a constant factor in South SF. Industrial pollution from the past has left residues on older roofing materials. Fog density near the bay is high. — are what we plan the work around, not an afterthought.
Every roof in South San Francisco answers to the same forces: a Coastal/industrial, windier than SF, heavy fog, 20" annual rainfall, and an aging housing stock dominated by Post-war industrial-adjacent housing, mixed residential/commercial. The specific local stressors that decide how long a roof actually lasts here: Strong bay winds are a constant factor in South SF. Industrial pollution from the past has left residues on older roofing materials. Fog density near the bay is high. We've spent enough time on South San Francisco roofs to know which failure modes show up first, and we plan shingle, tile, metal & flat roof systems around them rather than discovering them halfway through the job.
All the major ones — composition/asphalt shingle, concrete and clay tile, standing-seam metal, and flat-roof membranes (TPO, EPDM). The right pick for your South San Francisco home depends on pitch, exposure, structure, and how long you plan to keep the house.
Asphalt is lighter, cheaper, and fine for most South San Francisco homes at 25–30 years on an architectural shingle. Tile lasts 40–50 but needs the structure to carry the weight. We'll tell you honestly which your home is built for.
Yes. If your South San Francisco property sits in a Wildland-Urban Interface zone, the assembly has to be Class A fire-rated — that narrows the material choices, and we build to that standard where code requires it.
