| Built-up Roofs (BUR)

Built-up Roofs (BUR), often referred to as tar and gravel roofs, are among 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. BUR can be applied hot, cold or ballasted.

| Thermoplastic Polyvinyl

  Chloride (PVC) Roofing

Thermoplastic Roofing (PVC)

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. PVC can be applied mechanically fastened or fully adhered.

 | Modified Bitumen (MOD BIT)

Modified Bitumen (MOD BIT) 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. MOD BIT can be applied hot, with a torched cap application or as a self-adhering peel and stick (flameless) application.

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 that 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 making them highly resistant to wind and weather factors. TPO can be mechanically fastened or fully adhered.

Ethylene Propylene Diene Terpolymer (EPDM) is a synthetic rubber membrane that is extremely durable. Available in either black or white, it is available in 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. EPDM can be applied mechanically fastened, fully adhered or ballasted.

The safety of our employees and customers matters to us, so all our roofers are certified to perform services in compliance with the local, provincial and federal legislation. We take great pride in our work and continue to maintain the quality of customer service as your go-to roofing company.
