PART 1 Comparing Rubber Flat Roofs: EPDM, TPO, and Modified Bitumen - Pros, Cons and Warranty   you may be wondering which flat roof is better for your commercial or industrial building. At AZ Roofing, we specialize in installing and maintaining TPO and EPDM rubber roofs, and we have found that these two types of roofing offer the best combination of durability, flexibility, and energy efficiency. EPDM, or ethylene propylene diene monomer, is a synthetic rubber roofing membrane that is known for its durability and flexibility. It can withstand harsh weather conditions and is resistant to UV rays, ozone, and extreme temperatures. One of the biggest advantages of using EPDM on flat roofs is its ability to expand and contract with temperature changes, which helps to prevent cracking and splitting. Additionally, EPDM roofs come with a warranty of 20-30 years, providing long-term protection for your building. TPO, or thermoplastic olefin, is a thermoplastic roofing membrane that is known for its energy efficiency and reflectivity. It can reflect up to 85% of the sun's rays, which helps to reduce the amount of heat absorbed by the roof and lower cooling costs. TPO roofs also come with a warranty of 20-30 years. While Modified Bitumen is also a durable and water-resistant option but it is not as flexible as EPDM or TPO and may be prone to cracking and splitting over time, especially in areas with severe temperature changes. It also comes with a warranty of 10-15 years.
