Single-Ply Roofing in Fresno, CA

Commercial membrane roofs

Single-ply roofing membranes for commercial use have grown in popularity over the past 30 years, and due to their flexibility, relative ease of installation, and competitive price, it is no wonder that building owners and facilities professionals in Fresno County are interested. One of the benefits of installing single-ply commercial membranes is they are manufactured in a factory to strict quality control requirements that minimize the risk inherent in built-up systems. This consistency in the quality of the products is undeniably one of its selling points.

The SPRI (Single Ply Roofing Industry) identifies three major categories of single ply membranes: thermosets, thermoplastics, and modified bitumens.

Thermoset membranes

Thermoset membranes are compounded from rubber polymers. The most commonly used polymer is EPDM. Another thermoset material is neoprene, although this particular formulation is no longer widely used for roofing. Commercial thermoset membranes are successful for use as roofing materials because of their proven ability to withstand the potentially damaging effects of sunlight and most common chemicals generally found on roofs.

Thermoplastic membranes

Thermoplastic membranes are based on plastic polymers. The most common thermoplastic is PVC which has been made flexible through the inclusion of certain ingredients called plasticizers. Most commercial thermoplastic membranes are manufactured to include a reinforcement layer, usually polyester or fiberglass, which provides increased strength and dimensional stability.

Modified bitumen membranes

Modified bitumen membranes are interesting hybrids that incorporate the high tech formulation and prefabrication advantages of single-ply with some of the traditional installation techniques used in built-up roofing. These materials are factory-fabricated layers of asphalt, "modified" using a rubber or plastic ingredient for increased flexibility, and combined with a reinforcement for added strength and stability.
