What Is Torch Down Roofing?

Torch down roofing — also called modified bitumen or torch-applied membrane — uses layers of asphalt and polymer-modified bitumen that are literally torched (heat-welded) to the roof deck, creating a seamless, highly waterproof membrane. It's one of the most common flat roof systems in Los Angeles.

Golden State Roofers Sun Valley has years of experience installing and repairing torch down roofing throughout Sun Valley and Los Angeles County. We apply both single-ply and multi-ply systems with granulated mineral cap sheets for UV protection.

Why Torch Down?

Benefits of Modified Bitumen Roofing

💧 Superior Waterproofing

Heat-welded seams create a continuous, seamless membrane — virtually eliminating the seam failures that plague other flat roof systems.

🕑 15–20 Year Lifespan

A properly installed multi-ply torch down system will last 15–20 years, and many last longer with routine maintenance.

☀ UV Resistant

Granulated mineral cap sheets reflect UV rays and protect the membrane, reducing surface temperatures and extending roof life.

🔥 Torch Down is Proven

Modified bitumen has been the go-to flat roof system in Southern California for decades — a time-tested solution for LA's climate.
