Unlike Built-Up Roofing Systems (BUR), which are constructed on-site, Single Ply Membranes consist of flexible sheets of compounded synthetic materials manufactured to strict quality control specifications and thicknesses.
These prefabricated sheets are known for their flexibility, and can be applied to virtually any roof surface. These types of roofing systems are popular due to their long-term weather ability as well as their resistance to temperature extremes, ultra-violet light, ozone, and moisture.
Single-Ply roofing products consist of many different types and grades of thickness. They are categorized into three main groups by the Single-Ply Roofing Institute (SPRI):
Modified Bitumen (MB) – An asphalt-based system, similar of the Built-up-Roof (BUR) and designed for buildings with low-slope or “flat” roof structures. Modified Bitumen systems offer a broader array of options than BUR, and are typically furnished with white granules, but also offer color choices to match asphalt shingles or to complement the building’s design.
Thermoplastic (PVC, TPO) – Durable yet lightweight and energy efficient, Thermoplastic Roofing Systems provide the proven flexibility and weather resistance of EPDM Roofing Systems as well as high solar reflectivity. Thermoplastic Roofing Systems are environmentally friendly, as well as quick, clean and easy to install.
Thermoset (EPDM) – Offering excellent resistance to sunlight, moisture, ease, speed, and cleanliness of installation, EPDM materials have been used since the early 1970’s, and are highly adaptable. (For more information, please see our EPDM page here).
