Flat Roofing with Roof Pro Plus
At Roof Pro Plus, we only use the most effective and durable materials and methods for flat roofing. The four most common types of flat roofing include Thermoplastic Polyolefin (TPO), Ethylene Propylene Diene Terpolymer (EPDM), Torch Down, and Built-Up Roof (BUR).CALL NOW
Learn more about the different types of flat roofing materials that we use, and the materials that we stay away from!
Thermoplastic Polyolefin (TPO)
Thermoplastic Polyolefin is a flexible and hot air welded roofing membrane. While the width of the TPO membrane depends on the manufacturer, the length is typically 100ft.
Suitable for a variety of low slope applications, UltraPly TPO features a white, tan, or grey reflective surface that can help reduce a building’s cooling requirements. TPO is highly resistant to tears, impacts, and punctures – providing flexibility that allows for building movement.
Ethylene Propylene Diene Terpolymer (EPDM)
The Ethylene Propylene Diene Terpolymer rubber roofing membrane has been one of the best choices for those in the low-slope roofing industry for years – due to its extremely durable synthetic rubber.
EPDM’s primary ingredients, ethylene and propylene, are derived from oil and natural gas, and the material is available in both black and white. Sold in a broad variety of widths, ranging from 7.5 feet to fifty feet, and in two thicknesses, 45 and 60 mils, EPDM can be installed fully adhered, mechanically attached, or ballasted. With EPDM, seams of the roofing system are sealed with liquid adhesives or specially formulated tape.
Torch Down systems involve the heating of adhesive, as the material is unrolled. Similar to tar and gravel roofing, the Torch Down roof consists of layers of fiberglass and polyester with bitumen – that are added to the regular tar and gravel layering system.
These extra sheets are torched down in the overlap areas during the installation process, using large flame throwing torches that melt the asphalt at the seams, joining them together. The final result is the vulcanization of a large rubber sheet onto a fiberglass base.
Also called Modified Bitumen, due to the mixing of asphalt with rubber compounds, Torch Down roofing provides additional strength and resistance to a flat or low-sloped roof, and it is more attractive than standard tar or gravel roofs. Torch Down is not, however, suited to areas prone to high rainfall or snowfall.
Flat Roofing Products Not Used By Roof Pro Plus
Due to its smell, mess, and weight, Roof Pro Plus does not work with traditional hot-tar-and-gravel Built-Up Roof (BUR) flat roofing materials. While BUR material is the most commonly used roofing material for low slopes (due to its affordability), BUR is not recommended for occupied homes, and the material is therefore not offered nor installed by Roof Pro Plus.
