Bitumen Modified Torch Down Roofing
The modified bitumen torch down roof consists of layers of fiberglass and polyester with bitumen that are added to the tar to produce excellent waterproofing capabilities. Sheets are torched down during the installation process, using flame torches that melt the asphalt and join the layers together, which is the origin of “torch down roofing”. The final result of the process is vulcanization of a large rubber sheet onto a fiberglass base. Also called modified bitumen, due to the mixing of asphalt with rubber compounds, torch down roofing provides additional strength and resistance to a flat or low sloped roof. A torch down roof is also significantly more attractive than a standard tar and gravel roof.
