Firestone Torch-Down Roofing System Explained

Torch-down roofing is a multi-layer SBS-modified asphalt membrane heat-welded directly to the roof deck using a propane torch. The torch melts the asphalt-saturated underside of each roll as it’s unrolled, creating a permanent waterproof bond that fuses overlapping seams into a single continuous membrane. It’s the gold-standard flat roofing system for Hudson County’s freeze-thaw climate — and it’s what we install on the majority of our Hoboken brownstones, Union City row homes, and commercial buildings. Nothing else matches it for longevity in our climate. The heat-fused seams turn the entire roof into one continuous waterproof sheet — no glue lines to peel, no fasteners to back out, no welds to crack as the building shifts. Done right, a Firestone torch-down system routinely outlasts every other flat-roof method on the market and shrugs off the punishing freeze-thaw cycles that wreck lesser systems inside a decade.
