Coal tar pitch roofing materials.

A roofing demolition blade built to cut gummy materials including tar and gravel modified roofing coal tar pitch and more. Coal tar pitch is melted on site in an industrial kettle and applied to the roof as a hot liquid. Durapax specializes in coal tar roofing systems built up with multiple layers of coal tar coated glass felts or coal tar organic felts and hot mopped coal tar roofing pitch finished with a coal tar flood coat and gravel. Built up roofing in which coal tar pitch forms the waterproofing component of the roof membrane.

Coal tar pitch is a thick black liquid that remains after the distillation of coal tar. Historically coal tar pitch was used as a component on the first sealed roads has served as a heating element and was used to manufacture paints synthetic dyes and photographic materials.
