Here is how our flat roofing process works near Foster City:
ROOF EXPRESS specializes in flat and low-slope roofing systems for residential and commercial properties throughout Foster City. Flat roofs are common on Bay Area buildings — from San Francisco row houses and garage tops to large commercial warehouses and retail centers. Our crews are factory-trained on every major flat roof membrane and coating system, ensuring watertight installations that stand up to the Bay Area's wet winters and foggy summers.
TPO (Thermoplastic Polyolefin) is one of the most popular flat roofing membranes in Foster City for both commercial and residential applications. TPO reflects UV radiation, keeping buildings cooler and reducing energy costs. Our crews hot-air weld every seam for a monolithic, leak-proof bond that outperforms adhesive-based systems. TPO meets California Title 24 cool roof requirements out of the box, which can qualify your Foster City property for utility rebates. We install 60-mil and 80-mil TPO in white, tan, and gray to suit your building's aesthetics. Learn more in our guide: Flat Roof: TPO vs Modified Bitumen.
Modified bitumen is a proven flat roofing system that has protected Bay Area buildings for decades. Our torch-down application creates a heat-fused bond between layers, producing a strong, flexible membrane that handles thermal movement and ponding water. Modified bitumen works well on residential flat sections, detached garages, carports, and additions in Foster City. We install two-ply and three-ply systems with granulated cap sheets for added UV protection and durability. This system is ideal for complex roof shapes with multiple penetrations.
Silicone roof coatings can restore and extend the life of your existing flat roof in Foster City by 10 to 15 years — without a full tear-off. We apply high-solids silicone coatings over properly prepared existing surfaces to create a seamless, waterproof barrier. Silicone coatings resist ponding water, UV degradation, and mold growth. They are an excellent option for Foster City property owners who want to extend their roof's service life at a fraction of the cost of a full replacement.

EPDM (Ethylene Propylene Diene Monomer) rubber roofing offers long-term durability and flexibility for flat roofs in Foster City. EPDM is available in 45-mil and 60-mil thicknesses and can be fully adhered, mechanically fastened, or ballasted depending on your building's requirements. It handles temperature swings well and has a proven track record spanning 40+ years in commercial applications.
Ponding water is one of the biggest threats to flat roofs in Foster City. Water that sits for more than 48 hours after a rainstorm accelerates membrane degradation, promotes algae growth, and can cause structural damage. We solve ponding water problems with tapered insulation systems that create positive drainage slopes, interior drain installations, scupper and overflow drain additions, and cricket or saddle framing behind parapet walls. Proper drainage design is critical for every flat roof project in Foster City.
California Title 24 energy code requires cool roofing on most flat roof installations and replacements. All of our flat roofing systems in Foster City meet or exceed Title 24 requirements for solar reflectance and thermal emittance. TPO and silicone coatings qualify as cool roofs without additional treatments. We handle all Title 24 documentation and energy compliance paperwork as part of your project.
We also offer roof repair, roof replacement, residential roofing, commercial roofing, gutters, skylight installation, and asphalt shingle roofing in Foster City.
Foster City was built on reclaimed bay land at just 6 feet above sea level, creating persistent moisture conditions. The lagoon system throughout the city adds to the humid environment, accelerating corrosion on metal roofing components. Foster City gets regular fog. This means moisture control is important for every flat roofing job. Salt air can corrode metal parts. We use stainless steel flashing and fasteners to prevent rust.
