EPDM roofing may be the right choice for your warehouse, factory or other commercial building. Here’s what you need to know about this versatile material.
What Is EPDM Roofing?
EPDM roofing is widely used on low-slope and no-slope roofs all over the United States. Available in black or white, EPDM roofing is available in two thicknesses – 45 and 60 mils – and it can be mechanically attached, ballasted or adhered to your roof.
EPDM stands for ethylene propylene diene terpolymer, and it’s a strong, reliable synthetic rubber roofing membrane. It’s ideal for low-slope roofs, including those on commercial facilities. (It’s also commonly used on car ports and patio roofs, as well.) While most EPDM roofs are black, they are available in white, as well, which can increase their heat reflection capabilities and help reduce energy costs.
Benefits of EPDM Roofing
EPDM roofing offers a wide variety of benefits for your commercial roof. Here are just a few:
- Long lifespan
- Low need for seams
- High water resistance
- Fire resistance
- Ability to “settle” with a building
- Weather, UV Ray, Wind and Hail Resistance
- Ecological friendliness and energy efficiency
Benefits of EPDM Roofing Continued
With proper care, an EPDM roof can last longer than 50 years. Many come with 30-year warranties. Maintenance is typically very easy, as well – these roofs can be cleaned with dishwashing detergent, water and a medium-bristle brush.
High Water Resistance
This synthetic rubber roofing material is very water-resistant. The fact that it requires fewer seams than most types of commercial roofing materials makes it even more appealing when moisture, rain and snow are environmental factors.
Ability to “Settle” With a Building
Because the materials used to make EPDM are very flexible, these types of roofs can settle with a building.
Low Need for Seams
EPDM roofs are typically laid in one sheet whenever possible. The sheets are large, which minimizes the need for seams and cuts down on installation times.
The synthetic materials in an EPDM roof are extremely hard to ignite. In fact, they can slow a fire down considerably.
Weather, UV Ray, Wind and Hail Resistance
EPDM is extremely durable against wind and hail. Most is highly impact-resistant, which makes it a superior choice for commercial buildings in our area, where storm and hail damage is possible. These roofs are also highly resistant to the sun’s harmful UV rays. They can stand up to extreme temperatures without cracking, fading or deteriorating.
Ecological Friendliness and Energy Efficiency
EPDM roofing materials last a long time, and they’re recyclable. The materials themselves require very little energy to construct, and the rubber membrane doesn’t pollute rainwater, either. EPDM roofs can be extremely energy efficient, as well; they have what’s known as high emissivity, which means the material reflects heat energy from the sun back into the atmosphere. There are even ENERGY STAR®-approved coatings you can add to improve your EPDM roof’s performance.
How Much Does EPDM Roofing Cost?
There are several factors to consider when estimating the cost of your EPDM roof including:
- How big your roof is
- The current condition of your roof
- Which insulation you choose
- Your membrane choice
- Elements on your roof that roofer will have to work around
