Built Up Roofs

Built Up Roofs (BUR), often referred to as tar and gravel roofs, are one of the most common low slope and flat roofs. Multiple layers of roofing materials are sandwiched between layers of bonding materials, the most common being bitumen. Gravel is applied to hold down the roofing material and to offer UV protection.

Thermoplastic Polyvinyl Chloride (PVC) Roofing sheets are produced by rolling, spread coating or extruding and are often reinforced. Desired properties and flexibilities are achieved through additives. The seams are sealed by chemical or heat welding and are available in many colours with grey and white being the most common.

Adjoining sheets are overlapped, fastened and hot-air welded which makes it highly resistant to wind and weather factors.
