Whether you have been in your home or business for several years or recently acquired it, it is helpful to know key indicators of potential roof damage and problems. Signs of roof damage include attic leaks after a storm, shingle damage or color changes, and interior leaks. Fortunately, a good Roofing Contractor in Birmingham Al can help. Not all roofs are created equal. There are several differences between residential and commercial roofing. Damage to either can be expensive and requires professional installation with quality materials. Some of the primary differences are:
• Roofing Materials -: The following are usually limited to commercial roofing applications. Built-Up Roof or BUR, consists of many layers of roofing felt laminated with bitumen. Ethylene Propylene Diene Monomer (EPDM) is a rubber based material commonly used for low-sloping commercial roofs. Compared to BUR it is less expensive, easier to apply and lasts about 25 years. Membrane roofs or modified bitumen are frequently used for flat or nearly flat roofs sloping less than 1/4-inch per horizontal foot, to prevent leaks and move water off the roof. It is essentially asphalt combined with solvents and rubber modifiers. Commercial roofs often use single-ply roofing which are pliable sheets of synthetic material made in a factory setting according to strict standards. They provide a higher degree of versatility in how they can be attached. Materials used in both residential and commercial roofing applications include metal, asphalt, tile and ceramic. Wood or cedar shakes are sometimes used commercially but to a lesser extent.
• Roofing Design -: Commercial roofs are typically flat or very nearly flat (low-sloping) and generally cover a large surface area. They require special design considerations to address issues of equipment on the roof, snow bearing load and flat roofs frequently are not repairable requiring significant portions to be replaced. Commercial roofers must be skilled in dealing with obstructions such as ventilation pipes, air flow systems, and smoke stacks for example. Residential roofs usually do not have such obstructions other than a chimney and fireplace.
• Codes -: Commercial roofs have certain codes in place to address issues of wind resistance, fastening requirements, fire ratings and test standards.
