Modified Bitumen

Modified Bitumen or “torch-down” roofing got its name from the installation process which done by torching the sheets in the overlap area. Is like a large rubber sheet that’s actually vulcanized onto a fiberglass base sheet. Highly recommended for most flat roofs, torch-down roofing is similar to the tar and gravel roof. This roof adds layers of polyester or fiberglass with bitumen to the standard tar and gravel layering system. These additional layers add strength and resistance to this type of roof..

There are two type of modified-bitumen roofs - the plastic-based ones (APP) and the rubber-based ones (SEBS and SBS). The plastic-based membranes are usually installed using torches while the rubber-based membranes are installed using cold adhesives or hot asphalt. Most modified-bitumen roofs already have granulated surfaces so they are lighter than built-up roofs that have gravel surfaces. Modified-bitumen roofs may also be added as cap sheets on top of existing built-up roofs. This adds redundancy to the roofing as well as some flexibility.
