Torch-On Roofing
Flat Roof Waterproofing Built To Last Decades.
Heat-welded modified bitumen membranes — seamless, weatherproof, and engineered for residential, commercial, and industrial buildings.
Definition
What you're really buying
Torch-on roofing is a flat roof waterproofing system where polymer-modified bitumen membranes are heat-welded directly to the roof deck. The result is a fully adhered, seamless, watertight membrane that handles rain, snow, ice, UV, and ponding water — for 20–30 years.
Why it's a smart investment
- Properly installed systems last 20–30 years
- Seamless application eliminates leak-prone seams
- Withstands UV, extreme temperatures, and ponding water
- Ideal for flat and low-slope roofs (1:12 or less)
- Often installable over existing roofing — saves tear-off cost
- Walkable for rooftop decks and green roof systems
