1 Time Tested

EPDM is time-tested in Colorado conditions. White EPDM roofing systems have been used for more than 32 years in Denver, Colorado Springs and all across Colorado.

2 Superior Weathering Resistance

EPDM has advanced resistance to UV exposure, heat, and mold.  Colorado experiences ultra high UV exposure due to the elevations, white EPDM is proven to prevent UV degradation at these elevations.

» ASTM G155 for Xenon Arc = 25,200 kJ/mÇ for white EPDM
» ASTM D573 for heat aging = 68 weeks at 240°F
» ASTM G21 for fungi = zero (no growth)

3 Thickness

EPDM’s nominal 60 or 90 mils of weathering protection is significantly greater than the 20-25 mils over scrim of most plastic-based sheets. A-Denver Roofing’s white EPDM is also available in 115-or 145-mil FleeceBACK for added toughness to withstand Colorado’s harshest mountain environments.

4 Superior Hail Resistance

Numerous studies and real-world experience in Denver and Colorado Springs confirm that EPDM’s 465% elongation (ASTM D412) and weathering resistance result in superior hail damage resistance and UL2218 Class 4 rating. White EPDM remains flexible throughout its life cycle. This is one of the main reasons why A-Denver Roofing chooses white EPDM for use in hail-prone Colorado’s Front Range.

5 Energy Efficient

In southern Colorado, the solar reflective benefits of white EPDM helps to reduce cooling costs during the summer months. The cross-linked molecular nature of EPDM can handle the heat of southern Colorado climates.

6 Rooftop Safety

EPDM’s rubber surface provides more grip than white plastic-based membrane, which is important to maintenance personnel. This prevents risk and costly lawsuits to commercial building owners in Denver, Colorado Springs, and all across Colorado.

7 Stability

EPDM is the most dimensionally stable membrane, remaining flexible even in extremely cold conditions. Per ASTM D5279-08, EPDM is more flexible at 0°F than TPO at 100°F. This characteristic is important for Colorado roofs because the weather has dramatic and fast freeze thaw cycles that can damage less flexible membranes.

8 Repairability

EPDM rubber doesn’t need internal scrim like plastic backed sheets and remains repairable with peel & stick flashings even at the end of its service life. This characteristic lowers the total lifecycle cost for building owners who need to extend the life of their roofs due to budget constraints.

9 Quality Seams

Carlisle’s labor-saving Factory-Applied Tape and pressure sensitive flashings improve the quality and consistency of seams. Electrical seaming equipment consumes natural resources and is dependent on the applicator using correct speed, temperature, and pressure to avoid false or cold welds. These seams are proven to withstand Colorado’s harsh weather events.

10 Fewer Seams

White EPDM is available in large 16′-wide to 20′-wide sheets for adhered applications, resulting in up to 50% fewer seams compared to 10’ wide plastic based membranes. This results in less opportunities for failed seams, and less opportunities for leaks.
