Built-Up Roofing Membrane

Built-Up Roofing Membrane, commonly known as BUR, is composed of alternating layers of bitumen and reinforcing fabrics that create a finished membrane. This material is basically a tar-and-gravel roof that has been used in the U.S. for over 100 years. The number of layers that it’s built with can be adjusted to control costs and meet durability requirements. Additionally, a BUR system inherently incorporates insulation properties in the design because of the multiple layers, which can boost the energy efficiency of the overall roofing system. BUR is one of the most cost-effective and rugged roofing types available for low-slope roofs.
Modified Bitumen Roofing
Modified bitumen roofing is one of the most popular commercial roofing systems on the market. This asphalt product is a great choice due to its tear-resistance, energy efficiency, flexibility, and low maintenance characteristics. These systems are usually fastened to commercial rooftops as two-ply systems and adhered to the roofing deck for the best stability and protection. Modified bitumen roofs are stronger than other flat roof types, so if you expect a lot of foot traffic on your roof, modified bitumen may be the best choice for you.
Thermoset Roof Membrane (EPDM)
Thermoset roof membrane, known as EPDM, offers long-lasting durability and versatility. It is more simple to install and easier to maintain and repair than many other commercial roof types. Constructed from a single-ply rubber material, EPDM has a strong resistance to ultraviolet light and ozone. Other benefits include greater flexibility in colder temperatures, resistance to certain kinds of solvents and its reflective properties help keep cooling costs down.
Thermoplastic Polyolefin (TPO) and Poly Vinyl Chloride (PVC)
Thermoplastic Polyolefin (TPO) and Poly Vinyl Chloride (PVC) roofing systems are lightweight, highly reflective and provide excellent weathering and resistance to UV light, punctures and tears and chemicals and bacterial growth. These characteristics make thermoplastic roof membrane systems a popular choice for restaurants and other businesses that emit oils or fats from their ventilation systems. Other benefits range from a high-temperature tolerance to high resistance to fire and high winds.
