Flat & Low-Slope Roofing Systems for Bay Area Homes
Flat roofs demand specialized engineering that most roofers cannot deliver. From classic Eichler homes to modern builds and rooftop decks, we install high-performance membranes that eliminate ponding, resist UV degradation, and last 30+ years.
TPO & PVC Single-Ply Membranes
Single-ply membranes are the gold standard for flat and low-slope applications. TPO (Thermoplastic Polyolefin) and PVC membranes are heat-welded at the seams, creating a monolithic, fully waterproof surface with zero fastener penetrations exposed to the elements.
Our team is factory-trained in hot-air welding techniques that produce seams stronger than the membrane itself. We install these systems with proper insulation boards, tapered systems to eliminate ponding, and reinforced membrane at all penetrations and transitions.
- Heat-welded seams — stronger than the membrane itself
- Energy Star-rated white reflective surfaces
- Chemical & grease resistant (ideal near kitchens/vents)
- 25–30 year manufacturer warranties available
Modern Eichler Home Flat Roof Upgrades
The Bay Area is home to thousands of iconic Eichler and mid-century modern homes — most built with flat or very low-slope roofs using outdated materials like tar and gravel that have long since exceeded their useful life. We specialize in upgrading these roofs to modern, high-performance systems without altering the home's architectural character.
Our Eichler roof upgrades include removing the old built-up system, adding rigid foam insulation to meet current energy codes (Title 24), and installing a new TPO or modified bitumen system with a reflective white surface that dramatically reduces cooling costs during Bay Area summers.
Absolute Waterproofing & Ponding Protection
Standing water is the number one enemy of flat roofs. Even a well-installed membrane will degrade years faster if water ponds in the same spot repeatedly. Our systems eliminate ponding entirely through precision engineering.
Tapered Insulation Systems
Custom-cut rigid foam boards that create positive drainage slopes across the entire roof surface, directing water toward internal drains or scuppers.
Reinforced Membrane Details
Every pipe penetration, curb, corner, and transition gets reinforced membrane layers with factory-molded flashings — the areas most vulnerable to leaks.
Internal Drain & Scupper Design
We design and install strategically placed drainage points with proper overflow protection, preventing catastrophic water accumulation during heavy Bay Area storms.
