Built Up Roofs
(BUR)
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
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.
Modified
Bitumen
Modified Bitumen is an asphalt-based roofing system designed for flat and low-slope roofs. Synthetic polymers are added to create elasticity especially in cold temperatures. It has numerous surface options and colours. It can be installed by torching or by rolling on self-adhering sheets. It has a proven record of performance and waterproofing.

Thermoplastic Polyolefin Roofing (TPO)
Thermoplastic Polyolefin Roofing (TPO) membrane has become a very popular roofing material consisting of single ply reinforced fabric and rubber. It is considered an environmentally safe, "green" product which is installed using fasteners and plates along the edges. TPO can be fully adhered to a base. Adjoining sheets are overlapped, fastened and hot-air welded which makes it highly resistant to wind and weather factors.
EPDM
EPDM (Ethylene Propylene Diene Terpolymer) is a synthetic rubber membrane which is extremely durable. Available in either black or white, it is available is various thicknesses and widths. It can be installed mechanically adhered, fully adhered or ballasted. The seams can be sealed with liquid adhesives or specially formulated tapes. It can be used for waterproofing and some specific kinds of EPDM for ponds. It has become the standard for roof-top gardens.
