Common Flat Roof Types

Every building is different, and the best type of roof depends on your structure, usage, and design goals. The most popular flat roof options include:

TPO Roofing (Thermoplastic Polyolefin)

TPO roofing is one of the fastest-growing flat roofing systems thanks to its energy efficiency and reflective properties.

Perfect for commercial buildings in the San Francisco Bay Area, TPO roofing combines durability and eco-friendly performance in one cost-effective roofing solution.

PVC Roofing

PVC roofing systems provide excellent waterproofing, fire resistance, and energy savings. These single-ply membranes are ideal for large, low-slope roofs.

If you want a long-term roofing material that performs under pressure, PVC is an excellent choice.

Modified Bitumen Roofing

One of the most trusted flat roofing materials, modified bitumen combines asphalt and reinforced fiberglass for strength and flexibility.

Our modified bitumen roof installations ensure long-lasting performance and superior waterproofing.

Roofing Materials and Construction

Our flat roofing systems use industry-leading materials from trusted manufacturers. Each system is engineered for strength, flexibility, and water resistance — ideal for California’s mix of fog, sun, and rain.
