Flat roofing systems are traditionally found on commercial and industrial buildings but can also be installed on low sloped residential homes as well. The Roofers are well versed in a variety of different roofing systems that can be applicable for your next roofing project.
Modified bitumen systems were developed in Europe during the 1960’s and were brought to the North American marketplace in the early to mid-1970’s.
The essence of the membranes is in the controlled manufacture of a heavy roofing sheet (usually 120 to 180 mils thick) employing multiple layers of asphalt and reinforced around a core of plastic (APP) or rubber (SBS) modifiers.
These systems are then installed by heat welding, using special torching apparatus or hot mopped into place using new or conventional methods of asphalt application.
The special characteristics of mod-bit systems are in their toughness, light weight loading, and resistance to wind and fire. They also provide an easily inspected surface and long-term service expectancy.
Built-up roofing (“B.U.R.”) has long been considered the traditional roofing material in the Canada, and predominately found on commercial and industrial buildings. It enjoys a long and illustrious track record of success. The multi-ply configuration provides additional layers of protection against moisture penetration along with somewhat of a self-sealing property during warm weather.
In a B.U.R., the felts act as reinforcement for the thin layers of waterproofing bitumen (asphalt or coal tar pitch).
The system is typically surfaced with aggregate (typically pea-gravel) set in a flood coat of bitumen for purposes of reflecting ultra-violet rays, severe weather, and impact protection.
B.U.R. systems are durable, long lasting, and relatively resistant to construction and post construction traffic. They are appropriate for both new and replacement roofing.
Thermoplastic polyolefin (TPO) roofing membranes are a type of commercial roofing product that offers benefits both in terms of installation – relatively simple compared to other roofing products — and performance – resistant to ultraviolet (UV) rays. The term polyolefin comes from two words – namely polymer and filler.
Blending polymer and filler, such as fiberglass, carbon fiber and rubbers, creates a TPO single-ply membrane that is resistant not only to UV rays, but also to ozone and chemical exposure. The Roofers staff professional and seasoned installers for installing TPO roofing systems
