In warm climates, flat roofing is ideal. Since heavy snow build up is not an issue in the deep south, the region's structures do not require steep slopes. Flat roofs are easy to walk on when in need of repair, and they hold up well during severe weather. They are also less expensive to install than many other roof types and often last for 25 years or more. If the pitch is 3:12 or lower, the roof is classified as low slope or flat and can be constructed with one of five general membrane systems. They are BUR, metal panel, polymer modified bitumen sheet, single ply and spray polyurethane foam based systems. The professional staff members at Quality Exterior Services can answer questions about these durable membranes and provide matchless service to home and business owners.

Most flat roofs are constructed in three vital parts, including the very important weatherproof layer, the reinforcement component and the surfacing. The three sections work together to prevent water leaks, punctures and damage from exposure to hail, wind, sunlight and extreme temperatures. Although flat roofs are often installed on commercial buildings, they can be practical for some residential structures as well. Tar and gravel (BUR) is a good choice for houses because the layers of bitumen and felt create a strong sealant. A hybrid roofing system exists that places a polymer modified bitumen cap sheet together with a BUR two or three ply membrane. A typical modified bitumen sheet membrane is a two ply system that takes fewer hours to install than a BUR.

Due to the risk of water leaks, metal is normally reserved for steep slopes. The metal panel roofing system, however, is appropriate for flat roofs and serves as a firm water barrier since sealant can be applied to the seams. Steps need to be taken to safeguard against condensation build up on the underside of the panels. When single ply sheet membranes are made in a factory, they are either thermoset or thermoplastic and are constructed through one of three processes. Reinforcement layers may be added during spread coating, extruding or calendering. Most single ply roofing systems do not require a surfacing material.

A foam insulation is the first layer applied during the installation of a spray polyurethane foam based system. The elastomeric coating is then either sprayed or rolled on the top, although a membrane is sometimes used instead. The surface materials, which can be mixed with sand or mineral granules, may be silicone, acrylic, hypalon, butyl rubber or a type of polyurethane elastomer. Regardless of the flat roofing style, Quality Exterior Services services cover every aspect of the property owner's needs.
