High-Performance Torch-On Roofing Felt Rolls & Bitumen Membranes
Achieve a durable, completely waterproof flat roof installation with our premium selection of torch-on roofing felt at The Roof Shop. Engineered for exceptional longevity and strength, torch-on bitumen membranes are the industry-standard choice for professional roofing contractors sealing domestic extensions, garage roofs, commercial units, and heavy-duty structural decks. Using a traditional gas torch, these multi-layer felt sheets are hot-applied to melt the modified bitumen backing, creating an indestructible, seamless fusion bond that successfully resists extreme weather elements.
Our trade-grade built-up felt systems are manufactured with advanced SBS or APP modified bitumen formulations, ensuring the material retains superior low-temperature flexibility and high-tensile resistance against structural cracking or tearing over its lifespan.
Our Multi-Layer Torch-On Roofing Felt System Components:
- Mineral Cap Sheets: The critical outermost protective barrier for your flat roof system. We stock heavy-duty torch-on mineral cap sheets surfaced with natural slate granules in popular colors like Charcoal Grey and Green. These minerals shield the underlying bitumen layers from damaging UV radiation, thermal shock, and routine maintenance foot traffic.
- Torch-On Underlays & Sanded Felts: Designed to form the high-performance intermediate waterproofing core of a standard 3-layer torch-on system. Our polyester-reinforced underlays offer outstanding dimensional stability and tensile strength, smoothing over timber or concrete substrates before the final cap sheet is applied.
