How Long Does an EPDM Roofing Last?
This roof will keep you covered for a while
EPDM roofing is rubber roofing designed to be extremely durable, but just how durable is it? If you’re new to it, you can read more about what EPDM roofing is. But in this article, we’ll break down the nitty-gritty details of how long EPDM roofing lasts.
How Long Does EPDM Roofing Last?
EPDM roofing lasts around 30 to 40 years on average. The exact life span of EPDM roofing will depend on the climate/weather it endures, its level of maintenance, and restoration.
When comparing EPDM versus TPO roofing or PVC roofing, they all have pros and cons, but EPDM roofing often lasts longer than these alternatives.
Factors Influencing How Long EPDM Roofing Lasts
The exact longevity of EPDM roofing depends on a few key factors, which are important to consider when you compare the pros and cons of EPDM roofing.
Maintenance
Many roofing issues happen because of poor maintenance or no maintenance at all. Like anything in your home, maintaining EPDM roofing with proper cleaning and repairs is important to keep its quality up to par.
Installation Quality
The quality of installation is sure to impact how long an EPDM roof lasts. While it is possible to install it yourself, it’s best left to the pros. Research available roofers near you to find the best fit that will get the job done right.
Membrane Thickness
EPDM roofing can be made to different thickness levels—typically 0.40 to 0.90 mils. The different levels of thickness allow for different levels of durability and resistance to punctures. The thicker the membrane, the longer the roofing should last.
Roof Design
EPDM roofing is often used on flat roofs that cover non-living spaces. That being said, the flatness creates easy access for water to pool. A roof with EPDM designed with appropriate draining and sloping will last longer and mitigate water damage.
Chemical Exposure
EPDM roofing is resistant to most chemicals, but if the roof is near an industrial area or chemical plant, the effect of chemical oils and solvents can impact the roofing over time, causing it to break down more quickly. Fortunately, there are some protective seals you can install on EPDM roofing if needed to resist the effects of chemical exposure.
Signs It’s Time To Replace EPDM Roofing
Here are some of the signs that indicate it’s time to replace your EPDM roofing. Roof replacement cost will depend on the roof’s surface size and geographic location.
Maintenance Tips for EPDM Roofing
Here are some easy ways to keep up with the maintenance of EPDM roofing and help it last as long as possible.
Conduct regular roof inspections. You can hire a professional roofing contractor to conduct inspections and ensure the roof is in good condition.
Restore issues as needed. If issues with EPDM roofing do arise, be sure to take care of them promptly by hiring a roofing professional.
Clean your roof. An accumulation of debris or overall lack of cleanliness can have a serious impact on EPDM roofing’s longevity. Clean it regularly so this does not become an issue.
Warranties for EPDM Roofing
Depending on your provider, warranties for EPDM roofing can range from five to 30 years and cover the cost—or part of the cost—for replacing or repairing the roof. Some of the circumstances that these warranties cover are erosion, punctures, and tears—things often caused by weather damage.
To get a warranty for your EPDM roofing, you can ask your roof’s manufacturer or contractor or contact a third party organization that provides warranties in your area.
Repairing vs. Replacing EPDM Roofing
Choosing whether to repair or replace EPDM roofing depends on the extent of the damage and/or wear and tear incurred by the EPDM roofing. If the damage is severe, it may be worth it to replace the roofing completely. When choosing a roofer, compare what they would charge for replacement versus repairs to help inform your decision.
Frequently Asked Questions
Yes, you can install new EPDM roofing on top of old roofing, but there must be a barrier placed between the new and old. These barriers are often made of plywood or fiberglass.
Any EPDM roofing should be equipped with a proper drainage system to reduce the risk of water damage. Water can sit on EPDM roofing for roughly 48 hours before it becomes a significant problem that must be dealt with immediately.
