Benefits of Membrane Flat Roofing Systems
A membrane roofing system is an option for buildings with flat or low slope roofs. While they are most commonly used for commercial properties, their residential use is growing. Membrane roofs serve the same general function of preventing leaks and helping to move water off the roof to reduce ponding, but they have advantages over traditional, asphalt-based roofing systems (also known as built-up roofing – BUR) for flat roofs.
There are many benefits to flat roof membrane systems:
- Flat roofing membrane sheets are made from a variety of compound materials, but most likely either synthetic rubber (EPDM), thermoplastic (PVC or TPO), or modified bitumen. When installed, sheets of material are laid across the roof with edges bonded together either with hot-air welding or a specialized liquid adhesive, depending upon the material. When installed properly, membrane roofs have extremely strong seams that are completely waterproof. They’re typically attached to the underlying roof deck with fasteners.
- Flat roof materials are lighter than traditional BUR roofing materials and can often be installed over an existing roof without an expensive tear-off that can disrupt building operations. Mechanically attached membrane roof systems require no loud machines, hot tar or other hazardous materials, and generate no noxious fumes.
- Although available in other colors, thermoplastic roof membranes are typically manufactured in white and are highly reflective. This means that sunlight is reflected away from the building, not transferred inside in the form of heat. This saves energy and reduces utility costs. Reflective roof membranes also help preserve the effectiveness of roof insulation beneath the membrane.
- Built-up roofing systems are often covered with stone ballast, making it difficult to locate and repair leaks. Membrane roofs are usually not ballasted, which makes locating the source of leaks much easier. Also, in the event of a leak, compatible membrane patches can be easily applied by a professional roofing contractor.
- At the end of their useful lives on the rooftop, some membrane roof systems can be recycled rather than discarded into landfills. Some roof system manufacturers have recycling programs in place that turn old roof membranes into new products.
