Roofing is the covering of a structure, which includes all parts and materials required to support it over its roof, on top of rafters, providing maximum protection from the elements, especially rain, wind, sunlight, and extreme temperatures. A roof is often a structural part of a building envelope. It is typically the largest component in the total building, with the exception of any wall enclosures.
In residential construction, it is commonly built either as a single or sloped roof. Single roofing is a single flat roof, while a sloped roof is a roof whose pitch is parallel to the axis of the house. Roofing are available in different materials like asphalt shingles, clay tiles, slate, cedar shakes, and metal sheathing. They are also available in different colors, such as white, black, copper, green, brick, limestone, slate, terracotta, and silver. There are even hybrid varieties of roofing, such as gable and hipped roofs.
Roofing sheets are made of different composition of materials such as corrugated fiberglass, aluminum oxide, cellulose fiberglass, paperboard, paper, polystyrene, wood, rubber, wool, and polypropylene. Most popular roofing sheets are corrugated type, which are made of corrugated fiberglass. These sheets are very light weight, can easily be installed on corrugated bases, and provide insulation against ultraviolet light. Fiberglass is good for thermal regulation, which makes it perfect for hot climates. Corrugated sheets are also easy to install, but their installation requires a good adherence to building codes.
Snow sheets, which are often used for roofing covering, are manufactured using polystyrene, calcium carbonate, and zinc. These provide thermal resistance, are waterproof, and are water resistant when they come in contact with moisture. It is a better choice than asphalt, because it does not mildew and mold. However, these snow covers are dependent upon the climatic conditions, and you should make sure that you have these materials in your area to avoid premature wearing.
Roofing flashing is a specialized roofing material that is widely available in the market. Its basic function is to act as a water seal between the interior layer of the roof and the exterior. Flashing slope is dependent upon the type of flashing or corrugated roofing materials. It provides protection against water leaks, which means that it is necessary in every case.
Flashing slopes can either be vertical or horizontal. They can also be perforated, seamless, or coated with metal or mesh for durability and aesthetic appearance. For more information on finding the ideal slope, you can contact a roofing specialist. They will determine the most appropriate slope for your location, depending upon factors such as snowfall, wind, snow runoff, as well as the structure of your roof.
