Determining which roof system to install depends on a variety of conditions, but few are more important than your local climate. While all of our roof options perform admirable in virtually all weather conditions, certain systems are better equipped than others for specific climates. Offering the widest variety of roof systems, Rauth Roofing Limited can provide a roofing solution that will meet your needs as the best system for your building.
EPDM Roofing Systems
EPDM has established 50 years of excellence within the roofing industry. Its reputation of low maintenance and top-notch weathering characteristics makes it the ideal roofing option for many climates. In northern climates especially, the original black colour of EPDM membrane attracts the sun's solar energy, leading to significant reductions in heating costs during the winter months. The EPDM membrane may also help melt snow that can pool up on your roof and lead to potential structural damage if not removed in a timely manner.
TPO Roofing Systems
Thermoplastic polyolefin, or TPO, is the fastest-growing segment of the commercial roofing industry. Fueling this growth is the increased use of TPO in southern climates where cooling cost significantly outweigh heating cost. Sure-Weld TPO membrane is ENERGY STAR- qualified and CRRC (Cool Roof Rating Council) certified and has been directly attributed to a reduction in a building's energy consumption by greatly diminishing the cost of air conditioning.
PVC Roofing Systems
Polyvinyl Chloride (PVC) is a trusted membrane that has been performing admirably for decades in the European and North American markets. Another option for reflective roofing, Sure-Flex PVC membranes are ENERGY STAR qualified and CRCC certified and offer building owners a potential for decreased cooling costs. Sure-Flex PVC also offers excellent resistance to rooftop chemical attacks including acids, oils and grease.
Fleeceback Roofing Systems
FleeceBACK membranes are the ideal choice for buildings that require superior roof top protection and long-term durability. FleeceBACK membranes feature 45-, 60- or 90- mil EPDM or 45-, 60- or 80- mil TPO membranes joined with a strong 55- mil fleece. The combination of fleece and proven membranes create a rooftop system that can withstand extreme weather conditions. Often used with the FleeceBACK systems, FAST Adhesive is a two-component, low-rise insulating adhesive that offers superior strength and wind uplift resistance for up to 120 mph. Calrisle's new Flexible FAST Adhesive offers elongations of 150% and added puncture resistance. FleeceBACK and Flexible FAST are recommended for Roof Garden terrace or solar PV installations due to the added strength and durability.
The importance of a properly insulated building cannot be overstated. In fact, a building that incorporates insulation into its overall design can substantially lower energy cost throughout the life of the roof. Because of its superior R-value and excellent energy-efficient properties, Polyisocyanurate foam (polyiso) has become the industry's premier roofing insulation. Polyiso can be attached to appropriate decking materials with a variety of plates and fasteners or adhesives.
Warranted Peace of Mind
Total system warranties cover the repair of leaks from a variety of causes (including hail up to 2 inches and wind of up to 120 mph) and offering terms of up to 30 years, you can feel confident that your building is protected long term against an unlikely failure. You may even choose warranty options that protect against accidental puncture. The warranty process begins with a comprehensive inspection by the manufacture's field service representative, providing the building owner with even greater confidence that the roof was installed flawlessly.
Because of the fast and easy installation, ballasted roof systems are an extremely economical choice for large, wide-open rooftops. A popular choice for large-scale retail stores and warehouses, ballasted systems feature a loose-laid membrane that is covered and held in place by stone or pavers. The ballast helps to shield the membrane from inclement weather and extend the life of the roof. Recent research also indicates that ballasted roof systems may offer energy efficiency similar to light-coloured membranes, therefore helping building owners reduce their cooling cost.
ASHRAE, the California Energy Commission (CEC) and the City of Chicago have all updated their 'cool roofing' standards to accept certain ballasted assemblies as alternatives to reflective roofing systems. Drainage components can be incorporated to facilitate storm water retention and contribute toward LEED credits.
Providing a lightweight, easy-to-maintain option, mechanically fastened roof systems are seen within the roofing industry as an upgrade from ballasted systems. Mechanically fastened systems are help in place by the pates and fasteners that are secured through the membrane and into the deck. The most widely installed roofs in the commercial roofing industry, mechanically fastened systems are an ideal choice for areas that experience moderate winds.
Fully adhered system offer the highest degree of stability and uplift protection and are essential for high elevations or hurricane-prone areas where wind is a constant concern.
