The Best Materials for Flat Roofs in Asheville’s Weather Conditions

Asheville’s diverse climate, featuring cold winters, humid summers, and substantial rainfall, poses unique challenges for roofing. Flat roofs, popular on commercial and residential buildings, require materials that can handle this variability without compromising performance. Here, we discuss the best flat roofing materials tailored to Asheville’s weather conditions.

EPDM (Ethylene Propylene Diene Monomer). EPDM is a synthetic rubber roofing membrane known for its durability and versatility. Resistant to UV radiation, ozone, and extreme temperatures, EPDM performs exceptionally well in Asheville’s fluctuating climates. It’s also highly waterproof, making it ideal for the area’s heavy rainfalls. An EPDM roof can last up to 25 years if properly installed and maintained.

TPO (Thermoplastic Polyolefin). TPO roofing is another excellent option for Asheville properties. It combines durability with high resistance to UV rays and chemical exposure. TPO is also known for its energy efficiency, as its white reflective surface helps lower cooling costs during hot summers. The material is lightweight, reduces strain on building structures, and can last between 20 and 30 years with good care.

PVC (Polyvinyl Chloride). PVC roofing membranes are suitable for Asheville’s climate due to their strength and water resistance. This material is particularly adept at handling heavy rain, as its hot-air welded seams create a watertight bond that prevents leaks. PVC is also resistant to fire and chemicals and can contribute to a building’s energy efficiency due to its reflective properties. A well-installed PVC roof can last up to 30 years.

Built-Up Roofing (BUR).  BUR, or tar-and-gravel roofing, consists of multiple layers of bitumen and reinforcing fabrics. This type of roofing is valued for its durability and redundancy, as various layers provide enhanced protection against water. The gravel surface of a BUR system is excellent for UV protection and can endure the seasonal temperature swings prevalent in Asheville.

Each of these materials offers specific advantages that make them suitable for the demanding weather conditions in Asheville. When selecting a roofing material, consider longevity, maintenance requirements, and thermal performance.
