If you’re in the market for a new roof, you may find yourself wondering, “Which is better: EPDM or TPO roofing?” Both options have their merits and it can be a tough decision to make. In this article, we will explore the advantages and disadvantages of each type of roofing, providing you with the information you need to make an informed choice. Whether you’re a homeowner or a business owner, this article will help you weigh the pros and cons of EPDM and TPO roofing, ensuring you select the best option for your needs.
Durability
EPDM Roofing Durability
EPDM (Ethylene Propylene Diene Monomer) roofing is known for its exceptional durability. It is highly resistant to sunlight, ozone, and extreme weather conditions such as hail, wind, and rain. EPDM roofs can withstand temperature fluctuations without cracking or shrinking, making them a great choice for areas with harsh climates. The rubber membrane used in EPDM roofing is also resistant to water, making it an excellent choice for areas with heavy rainfall or snowfall. With proper installation and maintenance, EPDM roofs can last for up to 30 years or more.
TPO Roofing Durability
TPO (Thermoplastic Olefin) roofing is also known for its durability. It is highly resistant to UV radiation, thermal expansion and contraction, as well as chemical and microbial attacks. TPO roofs have excellent puncture resistance and can withstand hail and other impact-related damages. The heat-welded seams in TPO roofing provide an added level of strength and durability. With proper installation and maintenance, TPO roofs can last for up to 20-30 years.
Comparison
When comparing EPDM and TPO roofing in terms of durability, both options offer excellent longevity. EPDM roofing has a slightly longer lifespan than TPO, with the potential to last up to 30 years or more. However, TPO roofing still offers a respectable lifespan of 20-30 years. Ultimately, the choice between EPDM and TPO should be based on other factors such as cost, environmental impact, and energy efficiency.
Installation
EPDM Roofing Installation
EPDM roofing installation is relatively straightforward and can be done by both professionals and skilled DIY enthusiasts. The EPDM membrane is available in large rolls, which are cut to fit the dimensions of the roof. The membrane is then adhered to the roof using adhesives or mechanically attached with screws and plates. Seams are typically overlapped and sealed using specialized tapes or adhesives. Proper installation techniques are crucial to ensure the longevity and effectiveness of the roof.
TPO Roofing Installation
TPO roofing installation is similar to EPDM roofing installation and can also be performed by professionals or experienced individuals. The TPO membrane is available in rolls, which are cut and fitted to the roof’s dimensions. The membrane is then heat-welded together to create a seamless and watertight bond. Additionally, the membrane can be mechanically fastened to the roof using screws and plates, similar to EPDM roofing. It is important to follow manufacturer guidelines and industry best practices during TPO roofing installation to ensure optimal performance.
Comparison
Both EPDM and TPO roofing systems are relatively easy to install, and the installation processes share many similarities. However, TPO roofing requires heat-welding to create a seamless bond, which can be more challenging and time-consuming compared to EPDM roofing. The ease of installation may depend on the individual’s skill level or the availability of professional installation services in your area.
Cost
EPDM Roofing Cost
EPDM roofing is known for its affordability compared to other roofing options. The cost of EPDM roofing can vary depending on factors such as the size of the roof, location, and complexity of the installation.
