On the market, there are three common types of flat roofing systems that can be used on either residential and commercial applications. Usually, a flat roof comes with a 10- to 20-year warranty but can last up for 25 years if properly installed and well-maintained throughout its lifespan. Our residential roofers at Atrium Roofing take a closer look at these roofing systems below.
Built-up roofing, also called BUR, is the most common roofing membrane used on low-slope roofs. It is built with three or more alternating layers of reinforcing fabric and bitumen and capped off with a layer of aggregate such as stone or gravel, an excellent fire retardant. This membrane, however, tends to be extremely heavy and is quite messy to install, which is why it is not recommended for occupied buildings.
Modified Bitumen Roofing
Another membrane designed for buildings with low-slope or flat roof structures is the modified bitumen, a single-ply, asphalt-based roof replacement similar to an ice-and-water shield. It involves a peel-and-stick material that can be easily installed and has a light-colored surface that reflects heat. One downside to modified bitumen roofing is that its torch-down application can be a fire hazard if handled by inexperienced roofers.
EPDM or ethylene propylene diene monomer is an extremely durable single-ply membrane material. It is a type of synthetic rubber that is used in many applications. It offers better resistance to heat, light, and ozone than other unsaturated rubbers such as SBR or polychloroprene. However, this membrane is more vulnerable to punctures, and light-colored coatings recommended for warmer climates add at least 30% to the cost.
