WHAT IS EPDM ROOFING?

EPDM is a type of single-ply roofing membrane made from a combination of ethylene, propylene, and diene monomer. It’s a flexible, durable material that’s commonly used for flat roofs on both residential and commercial buildings. EPDM roofing is available in two main forms: black and white, with the black version being the more traditional choice, offering excellent UV resistance and heat retention. EPDM has gained popularity due to its longevity and high-performance qualities. Whether you’re installing it on a new construction project or replacing an existing roof, EPDM is known for being low-maintenance, affordable, and versatile.

BENEFITS OF EPDM ROOFING

Before installing EPDM roofing, it’s important to understand its key benefits. Here are a few reasons why this material is so widely used:

Durability EPDM is highly resistant to extreme weather conditions, including rain, snow, and UV radiation. It also performs well in both hot and cold climates, making it ideal for year-round protection. When properly installed, EPDM roofs can last 20-30 years, depending on the quality of installation and maintenance. Cost-Effectiveness Compared to other roofing materials such as metal or modified bitumen, EPDM roofing is relatively affordable. The material itself is less expensive, and installation is quicker, which can reduce overall costs. Additionally, EPDM is energy-efficient, which could help lower your utility bills by reducing the need for excessive heating or cooling. Low Maintenance Once installed, EPDM requires minimal maintenance. While regular inspections are recommended, you’ll find that this material is less prone to damage from wind or debris than other roofing systems. EPDM’s durability means it is less likely to develop leaks or wear down over time. Eco-Friendly Options White EPDM roofing reflects sunlight and can help keep your building cooler during hot weather, reducing cooling costs and contributing to a greener environment. Some manufacturers also offer recycled EPDM options, further reducing the environmental impact.

Easy Installation EPDM roofing is relatively easy to install, particularly when compared to other roofing materials. Whether it’s installed as a fully adhered membrane, mechanically attached, or ballasted, it offers flexibility during installation. It’s also compatible with a variety of substrates, making it a versatile choice for flat roofs.

THINGS TO CONSIDER BEFORE INSTALLING 
EPDM ROOFING While EPDM roofing has numerous advantages, there are some important factors to keep in mind before installation: 
 
Roof Slope EPDM is best suited for flat roofs or low-slope roofs (with a slope of less than 2:12). If your roof has a steeper pitch, other roofing materials like asphalt shingles or metal might be a better option. If your roof does have a slight slope, ensure that the roof drainage system is well-designed to prevent water pooling. Professional Installation is Crucial The success of your EPDM roofing system depends on proper installation. EPDM requires a precise installation process to avoid leaks and ensure maximum durability. Working with a professional roofing contractor who has experience with EPDM will ensure that the roof is properly installed and performs at its best for years. Temperature Considerations EPDM roofing is best installed in moderate temperatures, ideally between 45°F and 85°F (7°C to 29°C). If you’re planning to install EPDM during the colder months, you’ll need to take special care to ensure the material adheres properly to the surface. During installation, it’s important to avoid temperatures that could affect the adhesive used for bonding the roofing material. Potential for Punctures While EPDM is durable, it can be susceptible to punctures from sharp objects, such as fallen branches or heavy debris. Be sure to regularly inspect your roof for potential damage, and take preventive measures to clear debris away from the roof. Some EPDM roofing systems have additional protective layers to reduce puncture risk, so discuss options with your contractor. Color Choice EPDM roofing comes in both black and white options. Black EPDM is better at absorbing heat, which can be an advantage in colder climates or buildings where additional warmth is needed. White EPDM, on the other hand, reflects sunlight, which can reduce the heat absorbed by the building and contribute to cooling savings in warmer climates. Choose the color based on your climate and energy needs. Roof Ventilation Proper roof ventilation is important to prevent moisture buildup in your roof system, which can lead to mold, mildew, and premature roof deterioration. EPDM roofing is relatively breathable, but it’s still crucial to ensure your roof has sufficient ventilation, especially in climates with high humidity. 

HOW TO MAINTAIN YOUR EPDM ROOF

One of the most appealing aspects of EPDM roofing is that it requires minimal maintenance. However, periodic inspections can help to extend its lifespan and ensure it continues to perform at its best. Check for Tears or Punctures: Look for signs of physical damage such as tears, punctures, or blisters, especially after storms or heavy winds. Clean the Roof Surface: Remove debris such as leaves, branches, and dirt from the roof surface to prevent buildup and blockage of the drainage system. Inspect Seams: Ensure that the seams are properly sealed, as these areas are vulnerable to leaks. Check for Ponding Water: Make sure that water drains efficiently off the roof to prevent damage from standing water.
