What is a common material used for flat roofing systems?

EPDM rubber is commonly used for flat roofing systems due to its durability, flexibility, and ease of installation. Ethylene Propylene Diene Monomer (EPDM) is a synthetic rubber material that is particularly effective in environments with varying temperatures, as it can expand and contract without cracking. Its resistance to UV radiation and ozone makes it suitable for long-lasting performance in flat roofing applications, where water pooling can be a concern. This material also has excellent waterproofing properties, ensuring that the roofing system remains leak-free.

In contrast, materials such as asphalt shingles, concrete tiles, and wood shakes are more suited for sloped roofs. Asphalt shingles are designed to shed water and work best on pitched surfaces, while concrete tiles and wood shakes provide aesthetic value and durability but are not ideal for the flat layout because they can trap water and lead to leaks or damage over time. Therefore, EPDM rubber stands out as the most appropriate choice for flat roofing systems, offering specific benefits that address the unique challenges associated with flat roofs.
