Flat Roofing Near Me — Systems We Install in San Mateo

ROOF EXPRESS specializes in flat and low-slope roofing systems for residential and commercial properties throughout San Mateo. 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 Single-Ply Membrane

TPO (Thermoplastic Polyolefin) is one of the most popular flat roofing membranes in San Mateo 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 San Mateo 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 Torch-Down

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 San Mateo. 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

Silicone roof coatings can restore and extend the life of your existing flat roof in San Mateo 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 San Mateo property owners who want to extend their roof's service life at a fraction of the cost of a full replacement. Read our comparison: Flat Roof Coatings: Silicone vs Acrylic.

EPDM Rubber Membrane

EPDM (Ethylene Propylene Diene Monomer) rubber roofing offers long-term durability and flexibility for flat roofs in San Mateo. 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 and Drainage Solutions

Ponding water is one of the biggest threats to flat roofs in San Mateo. 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 San Mateo.

Title 24 Compliance

California Title 24 energy code requires cool roofing on most flat roof installations and replacements. All of our flat roofing systems in San Mateo 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.

Flat Roof Resources

We also offer roof repair, roof replacement, residential roofing, commercial roofing, gutters, skylight installation, and asphalt shingle roofing in San Mateo.

San Mateo Weather and Your Roof

San Mateo's central Peninsula location and varied terrain from bayshore flats to hillside homes creates diverse roofing requirements. The moderate climate is forgiving on materials, making this an ideal market for premium roofing products that maximize curb appeal and longevity. San Mateo gets regular fog. This means moisture control is important for every flat roofing job.

Flat Roofing Costs Near San Mateo

Flat roofing costs in San Mateo depend on the membrane system and roof size:

TPO membrane — $400 to $650 per square (100 sq ft). Energy-efficient, Title 24 compliant.

EPDM rubber — $350 to $600 per square. Long-term durability.
Silicone coating — $200 to $400 per square. Extends existing roof life 10 to 15 years without tear-off.
