Torch-on

Torch-On Roofing Systems (SBS) is a durable, multi-layer waterproofing system made from modified bitumen membranes that are heated with a propane torch and fused to a properly prepared roof deck, creating a seamless, monolithic barrier against rain, snow, wind, and UV exposure. During installation, the heat softens the bitumen so it flows into the substrate and around overlaps, forming strong, watertight seams that resist capillary action and thermal movement on flat or low-slope roofs. A typical build includes a reinforced base sheet and a mineral-surfaced or reflective cap sheet for added UV protection, traction, and long-term weatherability. Success starts with meticulous prep: the deck is cleaned, dried, and primed; drainage is verified; and penetrations, parapets, and edges are detailed with reinforced strips to maintain continuity at every transition. Crews align rolls, heat consistently, and roll forward to ensure uniform adhesion without fishmouths or trapped air; laps are welded to specified widths for predictable performance. The result is a robust membrane that handles foot traffic, wind uplift, and intermittent ponding better than many lightweight alternatives, making it ideal for residential additions, townhomes, commercial plazas, warehouses, and institutional buildings. Maintenance is straightforward—semiannual inspections, clear drains and scuppers, and timely touch-ups at high-wear areas—supporting a service life commonly in the 20–30 year range when installed by trained professionals. Safety is built into modern practice through hot-work permits, flame shields, fire watches, and clear setbacks from combustibles, so reputable contractors pair materials with certified installation and documented protocols. Owners can tailor performance and budget by choosing SBS membranes, tapered insulation for improved drainage, and cool-roof cap sheets that reflect sunlight and ease HVAC loads. Taken together, the system’s seamless bonds, reinforced strength, and proven durability make torch-on roofing a smart, long-lasting choice wherever reliable waterproofing is mission-critical.
