Commercial roofing is done over buildings that are used for commercial purposes to protect the roofs against all kinds of leakages and water shedding. It is extremely important for the materials used for the roofing must be long lasting and strong enough to withstand the severity of the environmental conditions. The materials should also be maintenance free to save you the expenses of remodeling the roofing frequently.
Metal : Metal or sheets of steel are one of the most significant and common type of material used for commercial roofing. These sheets of steel can prevent the harmful effects of moisture efficiently due to the fact that they are usually coated with zinc or other moisture preventing elements. Moreover, the fact that they are extremely environmentally friendly and recyclable also contributes to their popularity as an excellent roofing material. With reflective coating, metal roofs can significantly help in preventing the interiors of the commercial building from heating up, thereby lowering energy costs.
Polyvinyl Chloride : Polyvinyl chloride or PVC is one of the best options for roofing in commercial buildings, in which the interiors get heated up quickly. This is because PVC roofs are mostly light or white colored that prevails the absorption of heat by reflecting sunlight. This also results in reduced energy costs. Along with polyvinyl chloride, these roofers are also made up of layers of rubber spread all over the roofing surface, enhancing their longevity and making them highly resistant to any kind of environmental extremities. However, despite being extremely durable and long-lasting, polyvinyl chloride is not the greenest material for commercial roofing available in the market.
EPDM : EPDM is a synthetic material that is artificially made by combining polymers, ethylene and other chemicals. According to various researchers, this is the most durable material used for commercial roofing. One of the most significant factors that make EPDM a great roofing material is that it can provide excellent protection of the buildings against severe ultraviolet rays and ozone. Moreover, EPDM can efficiently withstand sudden temperature changes and can remain unaffected by chemicals. This material is available in rolls that can either be spread loosely over the roofing surface, or fixed to it.
PIC : A better and more developed form of EPDM, PIC or polyisocyanurate offers more advanced features and advantages than EPDM. Apart from providing protection against ultraviolet rays and ozone, the PIC can also efficiently protect against moisture and fire, thereby being an excellent roofing material for buildings used for the business of flammable chemicals or buildings that are located in areas prone to forest fires.
Bitumen : Despite the fact that bitumen or asphalt is more ideal for the constructions of roads that roofs, builders make them suitable as an excellent roofing material by adding special polymers to them. When reformed, bitumen becomes highly durable, strong and waterproof, and hence a great roofing material. Like EPDM, bitumen also comes in large rolls that have to be spread to cover the entire roof surface.
The choice of materials must be done on the basis of your specific requirements, preferences and budget, only after evaluating the pros and cons of each material.
