Thermoplastic Polyolefin (TPO) is a single-ply reflective roofing membrane made from polyprophylene and ethylene-propylene rubber polymerized together. It is typically installed in a fully adhered or mechanically attached system, allowing the white membrane to remain exposed throughout the life of the roof.
PVC roofing membrane is made from two layers of PVC roof material with polyester added in between the layers to act as a reinforcement. The layers in a PVC roof include additives to make the material flexible, UV stable, and to prevent curing. By adding a layer of acrylic coating to roof membrane, a PVC roof is made reflective and repellent to dust and dirt.
EPDM is an extremely durable synthetic rubber roofing membrane (ethylene propylene diene terpolymer) widely used in low-slope buildings in the United States and worldwide. Its two primary ingredients, ethylene and propylene, are derived from oil and natural gas.
Modified bitumen is a modern take on built-up roofing, a traditional roofing material also known as “tar-and-gravel” roofs. Modified bitumen roofs afford the same levels of protection as built-up roofs.
The SPF roof system is composed of two liquid chemical compounds called isocyanate and polyol that form the base of an adhered roof system. A protective surface is then applied to the foam to provide an added barrier against the elements.
Along with preserving and extending the life of your roof, coatings can provide a highly reflective surface that may help reduce energy costs by lowering the surface temperature of the roof. Additionally, coatings provide a seamless application that conforms to irregular roof surfaces, as well as seals cracks and splits in the roof surface. Coatings can be applied to address a variety of roofing concerns.
The majority of modern metal roofs are made from corrugated galvanized steel; a steel sheet coated with zinc. Copper, aluminum, stainless steel, and tin are also used in commercial metal roof applications. Coatings can be applied to provide additional waterproofing, anti-rust, and UV protection.
An asphalt shingle is a type of wall or roof shingle that uses asphalt for waterproofing. It is one of the most widely used roofing covers in North America because it has a relatively inexpensive up-front cost and is fairly simple to install.
Roof tiles are designed mainly to keep out rain, and are traditionally made from locally available materials such as terracotta or slate. Modern materials such as concrete and plastic are also used and some clay tiles have a waterproof glaze.
