How to Care for EPDM Rubber Roofing to Prevent Leaks and Damage

Do you have EPDM rubber roofing on your home or business? If so, then congratulations on choosing a material that offers outstanding longevity, durability, resilience to the heating/cooling cycle, and many other benefits. However, if you want to enjoy those benefits for as long as possible, and maximize the return on your roofing investment, you’ll need to make sure that you provide your roof with the right care and maintenance over its lifespan. Not sure what you need to do to care for something like a rubberized roof? It’s not all that complicated, and we’ll walk you through it below.

Understanding the Potential Problems

Does cleaning and maintaining EPDM rubber roofing focus strictly on the aesthetics of the roof? Actually, this is more about preventing potential damage to your roof while also ensuring that it looks good for as long as possible. For instance, in some climates, mold can gain a foothold and then grow on your rubber roof. Another problem is that contact with anything sharp can cause splitting, and in some cases, exposure to prolonged periods of heat with low humidity can also cause cracking. The right care and maintenance steps will help eliminate those issues.


We recommend that you clean your roof at least once per year, although twice per year is better. Spring and fall are the two best times as this allows you to address issues before extreme heat or cold become a problem.

Begin with a soft-bristled broom and sweep the roof. Start at the peak of the roof and work down, making sure to remove all dirt, dust, and debris. Of course, this material will fall to the ground, so you’ll need to clean it up from there, as well. If any of the debris gets into your gutters, make sure to clean it out immediately.

Next, you will need to wash your roof. You’ll need a bucket of warm water and some gentle dish soap. Use a soft-bristled brush here, as well. Do not use anything with stiff bristles to avoid scuffing your roof. Gently wash your roof and then rinse it clean with a garden hose.

Regular cleaning removes debris that can build up and cause threats, but also washes away mold and mildew. The water used in the washing and rinsing process will also help prevent problems that can stem from very low humidity levels that might lead to splitting in high-heat environments, as well.

Be Alert for Dangerous Situations

While regular cleaning is important, you also need to be aware of potentially dangerous situations that could lead to damage to your roof. For instance, tree removal on your property could cause branches to fall on the roof, potentially puncturing or tearing the EPDM rubber roofing. Storms are also serious considerations. While your roofing will stand up to threats like high winds, driving rain, and even hail better than other types of roofing, there is always the chance that storm winds will blow branches onto the roof, potentially causing damage. We recommend that you inspect EPDM rubber roofing after any storm to make sure that there is no danger. A quick visual inspection is usually all that is needed, coupled with possibly sweeping twigs and leaves off the roof.


While EPDM rubber roofing is strong and durable, it can be subject to damage from a number of sources. The right maintenance and cleaning strategy can help reduce your risk while maximizing the lifespan of your roof. Be proactive with your maintenance and you’ll encounter fewer problems.
