Commercial Flat Roofing

Where the slope rises less than four inches in a run of 12 inches — require special system installation to prevent leaks. Whether the roof protects an industrial building or your home, you want to choose the best system for your structure. Most low-slope roofs are now built or re-covered with one of four main material types, TPO, PVC, EPDM or Modified Bitumen.

TPO is a single-ply membrane with many excellent qualities. As a plastic, the seams can be heat welded for extreme durability. When considering high temperatures and direct sunshine on your roof, you can choose TPO in white for its reflectivity and ability to keep the interior of the building cooler than black or other dark hues. It holds up well in weather and offers flexibility to withstand building settlement and thermal expansion/contraction. With a tough hide, TPO resists punctures and, while not impervious, stands up well to moderate hail. Xtreme Roofing has certifications with all major manufactures to offer extended warranties on our TPO installation.

Before there was TPO, Polyvinyl Chloride was the predominant single-ply roofing material on the market. With similar qualities as TPO, architects and building professionals found PVC a good alternative to tar and gravel systems (otherwise known as built-up roofing, or BUR). Also, bendable and capable of heat welding, plus cool roof qualified, its main advantage over TPO comes from its ability to withstand a larger range of chemicals. PVC makes a great membrane roof covering for restaurants that vent the kitchen to the roof.

A modified rubber material, (EPDM) brings several great qualities to any flat roofing system. Supremely flexible, EPDM can withstand decades of hot/cold cycles and differential settling of the building without difficulty if fully adhered. EPDM can withstand nearly any chemical. Although the most-used color is black, EPDM comes in white, as well. Of all the single-ply membranes, EPDM can handle hail the best. Also, as a rubber product, EPDM easily resists punctures under ordinary conditions; however, gravel embedded in boot soles can cut the membrane, so it may not work well where there will be heavy foot traffic.
