TPO & PVC
EPDM (Ethyline Propolyne Diene Terpolymer) is a single-ply rubber roofing membrane that is resistant to a high degree of ozone, ultraviolet, weathering, and abrasion damage. Because of its tolerance to a wide array of weather conditions including wind and hail, and superb second generation application, EPDM is one of the most sustainable and environmental materials currently used in the industry.
Commercial Flat Roofs:
Thermoplastic roof systems are lightweight systems that include TPO (thermoplastic polyolefin) and PVC (poly vinyl chloride). Both are highly reflective roof membranes that provide excellent weathering and are highly resistant to ultraviolet light, tears, punctures, and most chemicals. Thermoplastic roofs have outstanding seam strength and are well suited for second generation applications.
Modified bitumen is an asphalt-based roofing system reinforced with either polyester or fiberglass. With excellent resistance to foot traffic, punctures, and tears, modified bitumen systems are a blend of traditional and modern roofing technologies. Two different polymers APP (Atactic Polypropylene polymer) and SBS (Styrene Butadiene Styrene) are used to modify the elasticity and temperature flexibility of the membrane.
Flat roofs are one of the most common types of roof for commercial buildings.
Commercial flat roofs are significantly more cost effective to build because they require less material due to the fewer square feet to be covered.
They are easier and quicker to install, which can translate to a significant savings for the building owner.
Owners have many types of flat roofing materials and membranes to choose from – rubber rolled roofing, EPDM, PVC, TPO, bitumen, modified bitumen , built-up roofing, metal and foam.
While there are many different color choices to choose from with roofing membranes, however many building owners choose to stick with white.
This can help reduce energy waste from cooling costs due to it’s reflective properties.
Air conditioners can be moved from the ground to the roof. Solar panels and satellite dishes are easier to install on flat roofs than on pitched ones. These items are then less obvious from the curb or parking lot.
Maintenance and drain cleaning is easier on flat roofs since workmen can walk easily and safely, regardless of weather conditions.
Spray Polyurethane Foam, commonly referred to as SPF, is an insulating plastic that is sprayed on as a liquid that quickly expands to several times its original thickness creating a water tight roofing material. It has been used as a roofing system since the 1960's, and is endeared by large businesses for its ability to save more than 30% annually on heating and cooling costs and effectively pay for itself in a few years! Because it is a continuous solid surface after application, it offers exceptional strength against high winds.
Built-up roof (BUR) systems consist of multiple plies of felts, fabrics, or mats that are laminated together with bitumen, either asphalt or coal tar pitch. The application incorporates alternating layers of plies and bitumen and is finished with a gravel application, a mineral cap sheet, or a weather resistant coating. BUR is designed to meet a broad range of waterproofing applications and is highly resistant to punctures and weathering.
SPRAY POLYURETHANE FOAM
Metal roofs are systems in which standing seams, R-panels, or corrugated metal panels are mechanically fastened to existing structure points. Metal roof provide architects, building designers, and owners with a variety of choices ranging from the type of metal to dozens of color options. Because of its excellent strength, durability, and fire resistance, metal roofs are the rising star of the energy-efficient and sustainable building movement.
