Torch-on felt is very fast and can be used on low-slope roofs. The material has a mineral finish that protects it from UV rays, rain, and other weather elements. In addition, it has excellent resistance to tearing.
Ethylene Propylene Diene Monomer
A synthetic rubber frequently used as a roofing material is ethylene propylene diene monomer. It has many advantages, making it a popular choice for many building owners and contractors.

EPDM has been a staple of low-slope commercial buildings for over 40 years. EPDM has significantly upgraded its performance in the past decade thanks to technological advancements. This has included introducing a reinforced sheet that has increased puncture resistance by 50%. Other enhancements include improved angle change securement and flashing details.
PVC
Many residential and commercial properties choose to have PVC flat roofs as their flat roof material of choice. These roofs have a lot of advantages. Durability, affordability, and energy efficiency are a few of them.

The insulation layer sits on top of the deck and is placed in a lower void section. This should be able to handle the imposed weight loads. A double-entry drain is also installed to facilitate water drainage at the deck level.
