Built-up Roofs (BUR)
Built-up Roofs (BUR), often called tar and gravel roofs, are among the most common flat roofs. Multiple layers of roofing materials, the most common being bitumen, are sandwiched between layers of bonding materials. Gravel is applied to hold down the roofing material and offer UV protection. BUR can be applied hot, cold, or ballasted.
Thermoplastic Polyvinyl Chloride (PVC) Roofing
Thermoplastic Polyvinyl Chloride (PVC) roofing sheets are produced by rolling, spread coating or extruding. PVC sheets are often reinforced. Desired properties and flexibility 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. PVC can be applied mechanically fastened or fully adhered.

PVC offers a seamless installation.

Modified Bitumen (MOD BIT)
SBS Modified Bitumen (MODBIT) is an asphalt-based roofing system for flat roofs. SBS stands for styrene-butadiene-styrene. Synthetic polymers are added to create elasticity, especially in cold temperatures. MODBIT has numerous surface options and colours. It has a proven record for performance and waterproofing. MODBIT can be applied hot with a torched cap or as a self-adhering peel-and-stick (flameless) application.
Thermoplastic Polyolefin (TPO) Roofing
Thermoplastic Polyolefin Roofing (TPO) membrane has become a popular roofing material consisting of single- ply reinforced fabric and rubber. It is considered an environmentally safe, "green" product installed using fasteners and plates along the edges. TPO can also be fully adhered to a base. Adjoining sheets are overlapped, fastened, and hot air welded, making them highly resistant to wind and weather factors. TPO can, alternately, be mechanically fastened or fully adhered.

TPO is resistant to UV Rays.

EPDM is recognized for its weather resistance.
Ethylene Propylene Diene Terpolymer (EPDM)
Ethylene Propylene Diene Terpolymer (EPDM) is a highly durable synthetic rubber membrane. It is available in black or white and in various thicknesses and widths. It can be installed mechanically, fully, or ballasted. The seams can be sealed with liquid adhesives or specially formulated tapes. EPDM can be used for waterproofing, and specific kinds of EPDM are used for ponds. It has become the standard for rooftop gardens. EPDM can be applied mechanically fastened, fully adhered, or ballasted.
