Commercial roofing – types

What you need to know about commercial roofing?

Simply saying commercial roofing is a group of materials used to cover and protect business, industrial and of course commercial buildings. Unlike residential building which have a more slopped roofs, commercial buildings need a different type of roofing style since they are mainly flat. So for commercial buildings contractors are using materials that are more durable, water resistant but also easy to repair and maintain.

Most commercial roofs are constructed using a technique that implies placing large sheets of material on rooftops and sealing them with strong adhesive to prevent leakage and to remove any unnecessary water from the roof. Therefore, roofing materials used for commercial roofing can be grouped in a couple of categories.


Thermoplastic roofing materials imply using plastic materials and PVC to produce plate that are then installed on buildings and afterwards fused together to create a single, smooth and even surface. They are quite resistant to any kind of weather conditions, chemical reactions and sun exposure. By using hot air welding, seams are created which provides even more strength and durability, eliminating all water coming through the roof.

Synthetic rubber roofing materials use a material called EPDM, like material mentioned earlier EPDM roofing is also made into sheets and placed on flat roofs and bounded to the roof with adhesive and tape. Contractors love EPDM since it can be easily installed and maintained with no problem. It possess high fire and cold resistance and provides protection from UV rays.

Unlike synthetic and thermoplastic roofing which are single ply roofing materials, bitumen based roofing materials are multi ply. So basically several layers are placed on your roof and then bounded with bitumen. Afterwards the surface is covered in granules material such as gravel to provide maximum energy efficiency. Types of bituminous roofing generally include modified bitumen and BUR (or built-up roof). Both are great at protecting the rooftop from collisions, ensuring no damage is done to it, which is extremely important in the case of commercial and industrial buildings.


And unlike cold and artificial roofing materials there is one more for the end – green roofs. They are becoming more and more popular choice for commercial roofing.  Basically, green roofs are first covered with a layer of waterproofing material. Then soil and plants are added, which provide extra insulation and, consequently, reduce energy costs. Green roofs are also an excellent alternative for those who wish to contribute to stopping climate changes – absorbing heat from the air, they reduce the so-called ‘heat island effect’ in urban areas.
