This roofing system is typically made of single-ply (TPO, PVC, EPDM), concrete, built-up roofing system, tar and gravel, modified bitumen, etc.
In fact now when new commercial roofing products have been introduced into the roofing system, they offer high resistance to temperature extremes as well as increase the environmental efficiency. Furthermore, the residential roofs are typically made of asphalt shingles or concrete tiles.

Built-Up Roofing or BUR Membrane
Built-up roofing is the combination of a good quality tar and gravel roof system. It is also known as the BUR roof. By composing various layers, the durability of the system increases. BUR has a low slope and cost-effective roof system.
Modified Bitumen Roofing
Popularly known as mod-bit roofing, this modified bitumen roofing system comprises unique chemical polymer and asphalt in layers offering flexibility and resistance to temperature. This commercial roof system can be secured as a two-ply system enabling protection and stability.
Commercial roofs can be created using hot asphalt sheets or adhesives and can be applied in different ways with hot or cold methods such as hot-mopped asphalt, self-adhesive sheets, torch-applied or cold-applied adhesives. The major benefit of using this commercial roofing system is, it can be installed all year long. Also, these roofs stay strong during storms.
Green Roofing System
Green roofing systems wins the race, when considering sustainable construction substance and designs. Comprising multiple layers and substances such as vapour controls, waterproof membranes, embellishing, allowing growth of vegetation.
After ensuring multi-layer green roofs, rain-water usage can be maximized, moreover reducing the options of inculcating in expensive drainage systems.
Thermoplastic or PVC & TPO Roof Membrane
TPO or Thermoplastic Polyolefin is a single-ply membrane which is polymerized together with polypropylene and ethylene propylene rubber. The membrane can be ballasted, adhered or mechanically attached when installing. It is commonly used in low-slope roofs.
Polyvinyl Chloride (PVC) comprises a double layer where the top layer has additives which makes the membrane UV resistant whereas the lower layer has plasticizers for flexibility.
These kinds of roofs are highly reflective, lightweight and resistant to UV rays. Popularly used in restaurants, hotels or buildings where oil is released from the ventilation systems.
EPDM Roofing
EPDM stands for “ethylene propylene diene monomer”. EPDM Roof or Thermoset roof is an easy to maintain, durable and multifaceted commercial roof. Currently, it is one of the most popular commercial roofing materials as well as installing the same is simple too.
Created using single-ply rubber material, natural gas and oil, the roof is low in cost with resilient strength. The roof strongly protects from ozone and ultraviolet light. Installing an EPDM roof has other benefits too such as reflective properties which in turn reduces cooling expenses, flexibility during colder temperatures and is resistant to acids and alcohols.
Liquid Applied Roofing
Liquid applied roofing membrane or fluid applied membrane has good waterproofing ability as it has the capability to reinforce in transitional areas on a roof. This roofing is also known as fluid-applied membranes and is sprayed or rolled generally in two separate coats.
Once the coating hardens, an elastomeric, flawless waterproofing membrane forms. The liquid applied membranes can be applied over surfaces such as brick, wood, concrete, TPO, PVC and many other surfaces. Whichever way this roofing is done, it does not emit harmful or strong odours.
Roof Coating Systems
This coherent covering comprises fluid applied membrane which is sprayed across the roof, hatches, around the pipes and everywhere around the rooftop. This coating system can stretch and can get back to its original shape. Acrylic and silicone are the commonly used roof coatings. Coating melts together when sprayed, leaving behind no seams.
Perfectly suitable for metal roofs as the coating system reduces energy consumption, keeps the buildings cool and protects from leaks further extending the life of the commercial roof.
