Roofing is the covering of a structure, with all structures and materials required to support it upon the exterior wall of that structure or upon uprights, giving protection from the elements (especially rain and sun) and against breakage. A roof protects the structural member of a building from external sources of damage such as rain, wind, snow, and sunlight. A well-planned and properly installed roof can save a business or home thousands per year in maintenance costs and replacement costs. The average lifespan of a roof, according to the American Society for Testing and Materials (ASTM), is from ten to twenty years; however, in the event of an unexpected and major leak or other damage, it may last anywhere from twenty to fifty years.

A roof consists of many layers, with each layer playing a vital role in providing protection and carrying the structure’s load. The first layer is called the underlying membrane, which provides a barrier to moisture and noise, while also helping to carry away rainwater runoff. The second layer is made of insulation or attic insulation (the applied insulation which goes between the membranes and roofing materials such as tiles, shingles, or sheathing) which not only insulates the roof but also provides protection from ultraviolet light damage (a common problem with flat roofs). And finally, the third layer, which is made of durable materials such as asphalt, is placed over and between the first two layers to provide a smooth, flat surface for the roof to rest upon.
Roofing is usually the most economical type of home improvement project, especially when compared to replacements of windows and other interior surfaces. Flat roofs are often the most expensive and easiest to install, although pre-cut and pre-seasoned membranes are available for some specialty applications. Furthermore, the most popular roofing material (no matter what the application) is usually asphalt. Asphalt is the most flexible and durable of all roofing materials, making it an excellent choice for both new and existing buildings. Its ease of installation and maintenance make asphalt the ideal roofing material whether you’re building a new house, a remodel, or a roof repair job.
