What Is Torch Down Roofing?

Torch-down systems fuse modified bitumen sheets with controlled heat to create a continuous, durable membrane. The multi-layer approach provides redundancy and strong resistance to water intrusion on commercial flat and low-slope roofs.

Ideal Commercial Applications

Torch-on roofing is widely used on warehouses, retail plazas, multi-unit buildings, and other commercial properties where a tough, proven flat roofing system is required.
