We offer several different types of commercial roofing products for installation throughout the Denver, Colorado area. New commercial roofs and roofing techniques offer increased energy efficiency. Two of the most popular commercial roofing systems in North America are EPDM and TPO commercial roofing systems designed for low slope roofs.
EPDM Commercial Roofing Systems
EPDM is an extremely durable synthetic rubber roofing membrane (ethylene propylene diene terpolymer) widely used in low-slope buildings in the United States and worldwide. Its two primary ingredients, ethylene and propylene, are derived from oil and natural gas.
EPDM membrane will not leech or emit hazardous chemicals. Unlike non-vulcanized elastomers that may begin curing in the field once exposed to moisture and heat, EPDM membrane has no shelf life. Its physical properties remain stable, which makes repairs much easier in the unlikely event of cuts or tears.
EPDM is available in both black and white, and is sold a broad variety of widths, ranging from 7.5 feet to fifty feet, and in two thicknesses, 45 and 60 mils.
EPDM membrane is manufactured in various thicknesses (.045" to .090" thick) and is available as a non-reinforced or reinforced sheet (depending upon application). Other thicknesses are also available for use in non-roofing applications as a special order.
Reinforced membranes contain an internal fabric that is completely encapsulated within the EPDM membrane sheet and is available in various thicknesses (.045" to .075"). A fleece layer can be added to the underside of the sheet that serves as a built-in underlayment for direct re-roof applications over certain types of existing roofing material.
Thermoplastic Polyolefin (TPO) Roofing Systems
Thermoplastic Polyolefin (TPO) is a single-ply reflective roofing membrane made from polypropylene and ethylene-propylene rubber polymerized together. It is typically installed in a fully adhered or mechanically attached system, allowing the white membrane to remain exposed throughout the life of the roof.
One of the factors that makes TPO roofing attractive is its reasonable cost. TPO resists mold growth, dirt accumulation, tears impact and punctures. It is made to be flexible and can allow for a building’s movement or settling.
TPO Roofing – Smooth: Smooth TPO Roofing is perfect for new construction or re-roofing where great performance is required at an affordable price. It features the same great performance that all TPO products offer — exceptional seam strength, puncture resistance, and outstanding long-term weathering.
Extreme TPO Roofing: Extreme TPO offers excellent performance over “standard” TPO membranes and the industry's best guarantee: up to 35 years! Specifically, this technology delivers next-generation performance against heat aging and UV degradation. A highly reflective and emissive white roof can help reduce energy costs and urban heat island effect.
