Durable EPDM synthetic rubber roofing for commercial and industrial buildings. Proven 50-year track record and extreme weather resistance.
EPDM (Ethylene Propylene Diene Monomer) is a high-performance synthetic rubber membrane that has been the backbone of the commercial roofing industry for over 50 years. Its exceptional durability and resistance to thermal shock make it an ideal choice for large-scale industrial and commercial flat roofs.
EPDM is a single-ply synthetic rubber membrane made of ethylene and propylene, with a small amount of diene. It is available in both reinforced and non-reinforced versions.
The only single-ply membrane with a 50-year track record of successful performance in diverse climates.
Remains flexible at temperatures as low as -40°F and can elongate over 300% to accommodate building movement.
Inherently impact-resistant, often achieving UL 2218 Class 4 rating for hail resistance.
Exceptional resistance to UV radiation and ozone, preventing common types of membrane cracking and degradation.

When it comes to longevity in the single-ply market, EPDM stands alone. With installations from the 1970s still performing today, EPDM (Ethylene Propylene Diene Monomer) offers a level of historical proof that newer thermoplastic systems simply cannot match. Capital City Roofing recommends EPDM for large industrial facilities and warehouses where the building may undergo significant thermal expansion and contraction. EPDM's rubber-like properties allow it to stretch and move with the building without stressing the seams or the substrate. While TPO is often favored for its reflectivity in warm climates, EPDM remains a powerhouse for large square-footage roofs due to its rapid installation with wide rolls (up to 50 feet wide), significantly reducing the total number of seams on the project. For clients concerned about energy efficiency, we offer high-performance white EPDM options that combine the durability of rubber with the reflectivity of a white 'cool roof'.
