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.

Los Angeles Roofing & Commercial Roof Repair has years of experience installing and repairing torch down roofing throughout Los Angeles 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.
