EPDM Rubber (Ethylene Propylene Diene Monomer)

EPDM rubber is a synthetic material that has become increasingly popular for flat roofing applications. It is highly durable and flexible, making it ideal for quickly covering large areas. Additionally, EPDM rubber is resistant to UV radiation, which helps prolong the material’s lifespan.


  • Long-lasting, with a lifespan of 20-30 years
  • Weather-resistant, handling extreme temperatures and weather conditions well
  • Low maintenance, only requiring periodic cleaning
  • Environmentally friendly, as it is recyclable


  • It can be punctured, although repairs are usually simple and inexpensive
  • Not the most aesthetically pleasing option

TPO (Thermoplastic Olefin)

TPO is another popular choice for flat roofs, particularly in commercial applications. It is a single-ply roofing membrane made from plastic and rubber materials. TPO is known for its energy efficiency. It reflects sunlight and reduces heat absorption, which can lower cooling costs for your building.


  • Energy-efficient, lowering energy consumption and costs
  • Resistant to mold, mildew, and algae growth
  • Durable, with a lifespan of 15-20 years
  • It comes in various colors, offering more aesthetic options

Modified Bitumen

Modified bitumen is an asphalt roofing material reinforced with either polyester or fiberglass. It is applied in layers, making it a strong and durable choice for flat roofs. Modified bitumen is also known for its excellent waterproofing capabilities, essential for preventing leaks and water damage.


  • Excellent waterproofing capabilities
  • High tensile strength, making it resistant to tears and punctures
  • It can be installed using various methods, such as torch-down, cold-applied, or self-adhering
  • It has a lifespan of 10-20 years, depending on the number of layers applied


  • It can be more expensive than other options, especially considering the professional installation.
  • It may require more frequent maintenance, such as resealing and recoating.

PVC (Polyvinyl Chloride)

PVC is a single-ply roofing membrane made from vinyl material. It has been used in roofing applications for decades. It is known for its durability and resistance to various chemicals, making it suitable for commercial applications where chemical exposure may be a concern.


  • Chemical and fire-resistant
  • Durable, with a lifespan of 20-30 years
  • Reflects sunlight, helping to reduce energy costs
  • Resistant to punctures and tears, making it a low-maintenance option
