Propane Torch Kits for Modified Bitumen

Modified bitumen roofing relies on heat to fuse layers into one watertight membrane. Our propane torch kits deliver controlled, even heat so the asphalt in the cap sheet melts and bonds fully to the layer below, rather than being tacked on with cold adhesive alone. This is the traditional application method for mod-bit systems, and it remains a solid choice on flat and low-slope sections where a fully adhered assembly is the right fit for the deck and the building.

Where Torch-Applied Systems Fit

  • Fully adhered cap sheets — the torch fuses the membrane directly to the substrate, with no gaps between layers for water to travel through.
  • Multi-layer flat roofs — often paired with built-up roofing assemblies where a heat-welded top layer finishes the system.

Checked Before and After

  • Core sampling tools — confirm what layers already exist on a flat roof before we decide torch application is the right approach.
  • Seam rollers & probes — every torch-welded seam is rolled and probed by hand along its full length before the job is called finished.
