The Commercial Roofing protects the building structure from the harsh climatic conditions and thus helps in the economic efficiency of the business. The commercial roofing not only protects the building structure from severe climatic conditions but also saves energy by minimizing the usage of electricity, thus saving on the overall power consumption. The main materials used in commercial roofing are steel that is pre-finished. It is an excellent weather tight roofing and also has a long warranty period of up to 30 years, aluminium and copper. They are cost effective as well.
These commercial roofing systems use two main varieties of membranes such as asphalt shingles and metal roofing membranes. The asphalt shingles are manufactured by applying liquid asphalt onto the steel sheets and heating it until the solid asphalt liquidizes. Then these sheets are swept off and joined together. The metal roofing membranes are manufactured by electroforming steel into sheets and applying them to the roofs. The rubber roofing membrane is made of thick round rubber that is rolled into sheets and is more economical than the other two click to read more.
In the manufacture of the commercial roofing, the two main varieties are flat sloped and polygonal flat-sloped. The flat sloped commercial roofing uses three or more layers of materials depending on the size and structure of the building. In the polygonal commercial roofing, there are two or more flat slope layers. The flat sloped commercial roofing reduces energy expenditures as it provides thermal resistance against the natural weather conditions and is less susceptible to external influences like winds, rain and snow. The roofing materials used are mainly steel, fibreglass and aluminum.
The flat-sloped roofing has fewer install challenges than the traditional residential roofing. However, it requires more maintenance and can be damaged easily. Therefore, this type of commercial roofing is not appropriate for those buildings that face frequent environmental threats. This type of commercial roofing is made up of single ply roofing materials which are usually made of wood with joint or tongue-and-groove backing.
Single Ply roofing is preferred for low-sloped roofs. It can also be installed easily and offers good insulation properties. Since there are no rafters in the case of single ply roofing, it does not have the problems of external expansion and contraction due to temperature change and external pressure. The cost of installing the commercial roof systems is lower than that of the residential roofing.
However, the cost of building a flat roof depends on various factors. These include the materials chosen, the size and structure of the commercial building, and even the amount of labor and other overhead expenses incurred. For instance, flat roofing materials cost more than flat roofs constructed from other materials such as clay tile, slate, and glass tile. In addition to that, the installation process of commercial roofing materials can be quite lengthy since there are numerous installation options and pre-installed features to consider.
