The membrane roof is the latest flat roofing technology. And this is the best choice for commercial constructions. This kind of roof is depending on the materials in a few different varieties, and that’s are:

  • PVC (polyvinyl chloride)
  • Neoprene (polychloroprene)

These roof materials are installed as thin or thick sheets as per the requirements and applied to the roof in a single layer. These kinds of roofs made of synthetic rubber which’s why they are more flexible and elastic. 

They can handle temperature changes very well and any other impact better than built-up roofs. EPDM and Neoprene roof can fix by adhesive and PVC roof can place by heat or solvent welded. 

Modified Bitumen Roofing

This kind of flat roofing was developed in 1960. And can say that this is a replacement technology for BUR or built-up roofing. Modified bitumen roofing wear layers or cap sheets. 

Bitumen roofing can be installed by using any number of techniques. According to the project’s requirements and material specified. The methods include for installation of the roof are; 

  • Cold applied

  • Torch applied
  • Self-adhered

The polymer used in the cap sheet provides elasticity and flexibility to keep the temperature down. SBS cap sheets can be installed by using cold adhesives or hot asphalt tar. And on the other hand, thermoplastic APP sheets can be installed by the torch applied method.


Built-up roofing

This is the oldest traditional roofing material option for making flat roofs. This is still a popular choice for solving low-pitch roofing problems. This roofing material can handle roof challenges much better than asphalt shingles. 

The installation process of built-up roofs needs a special kind of roofing layer. This layer applied by the roofing experts with a hot mop. Layering made by the coal-tar and hot-applied asphalt and then they blend with bitumen root felt. 

This fine mixture creates a strong and shiny roof. The layering has been repeated until all materials make 2-5 piles of thickness. The built-up roofing is work as a protective shield against the harsh weather and also protect from the UV lights. 

TPO roofing

TPO roofing is considered budget-friendly because it doesn’t require much money. TPO roof coating consists of white coating that allows to reflect heat and keep the surface temperature lower than dark coating roofs. 

TPO coating roof can keep your electricity bill down too. Along with that its surface is laminated, hence no tension of any kind of fungus and algae to grip on it. 

This is a single-ply and lightweight material that performs well on low-slope roofs. And best for flat roofing surfaces. But keep one thing in mind about the TPO roofing that it can become slippery in the rain, snow, or frosty conditions. 

Rubber roofing
