Rain or shine, EPDM roofs have to be on their best – especially once the summer heat and rains come pouring down. A roofing material that’s quite a popular choice for commercial and residential buildings due to its durability, flexibility, and relatively low cost, they’re susceptible to the harsh conditions of summer.
So, to prepare for high temperatures, UV radiation, and thermal expansion, you’ll want to take proactive steps in maintenance and care. Here are several steps to improve the durability of your EPDM roof during the hot summer months.
Regular Inspections
One of the most effective ways to maintain an EPDM roof is through regular inspections. Schedule at least two inspections annually—one in the spring and another in the fall. During summer, it’s crucial to perform additional inspections after severe weather events such as storms or prolonged heat waves. Look for signs of damage such as cracks, blisters, or punctures.
Clean the Roof Surface
Debris such as leaves, branches, and dirt can accumulate on the roof surface and trap moisture that promotes mold growth. Regularly cleaning your EPDM roof helps prevent these issues (along with timely inspections, as mentioned).
Address Ponding Water
Ponding water can degrade the roofing material over time and lead to leaks. Ensure your roof has adequate drainage by regularly checking and cleaning gutters, downspouts, and drains. If persistent ponding occurs, consult a roofing professional to adjust the slope or install additional drainage solutions.
Apply a UV Protectant
Prolonged exposure to sunlight can cause the material to become brittle and crack. To mitigate this, apply a UV protectant or reflective coating to the roof surface. These products are designed to reflect a significant portion of the sun’s rays and reduce heat absorption. Additionally, white or light-colored coatings can help lower the overall temperature of the building.
Ensure Proper Ventilation
Proper roof ventilation is critical in maintaining the durability of any roofing system, including EPDM. Adequate ventilation helps regulate the temperature within the roof structure, preventing excessive heat buildup that can stress the EPDM material. Ensure that your attic or roof space is well-ventilated. This can be achieved through the installation of vents, fans, or other ventilation systems designed to promote air circulation.
Trim Overhanging Branches
Trees surrounding your building can pose a threat to your EPDM roof, especially during summer storms. Overhanging branches can scrape the roof surface and cause abrasions or punctures. Fallen branches and leaves can also contribute to debris buildup.
Install Walkway Pads
If your EPDM roof is frequently accessed for maintenance of HVAC systems or other rooftop equipment, consider installing walkway pads. These pads provide a designated pathway, distributing weight more evenly and reducing the risk of damage to the EPDM membrane from foot traffic.
Monitor Temperature Fluctuations
EPDM roofs are designed to withstand a wide range of temperatures, but extreme fluctuations can cause thermal expansion and contraction, leading to stress on the material. Monitor temperature changes and consider installing a white or reflective coating to reduce heat absorption. This can help minimize thermal movement and extend the roof’s lifespan.
