How Long Does EPDM Roof Last

Are you tired of constantly worrying about the condition of your flat or low-slope roof? Do you want to invest in a roofing solution that will last for years to come? Look no further than EPDM roofing! This popular roofing material is known for its durability, flexibility, and waterproof properties. 

But how long can you expect an EPDM roof to last? In this blog post, we will uncover the truth regarding the average standard lifespan of EPDM roofs, and why it may be the perfect solution for your roofing needs. So, if you’re ready to say goodbye to the constant stress related to your flat roof, keep reading!

Characteristics Of EPDM Roofs

EPDM roofing, composed of Ethylene Propylene Diene Monomer, is widely utilized as a roofing solution for flat or low-slope roofs due to its properties of being durable, flexible, and waterproof. Since it can also withstand harsh weather conditions and UV light with ease, this synthetic rubber roofing can stretch or bend without cracking or breaking. 

In terms of maintenance, EPDM roofing is a breeze to take care of and has a long lifespan of around 50 years. Additionally, environmentally conscious individuals will be glad to know that EPDM roofs are made from recycled materials and are also recyclable. Finally, its budget-friendly cost compared to other roofing options makes it an economical choice for homeowners.

Average Lifespan Of EPDM Roofs

EPDM roofing boasts a reputation for longevity, which includes offering roof protection for numerous years. With an average standard lifespan of around 50 years or more, this durable roofing solution is ideal for flat or low-slope roofs. Also known for its resistance to harsh weather and UV light, EPDM roofing is a popular choice among homeowners and commercial building owners. 

When properly installed and maintained, an EPDM roof can provide long-lasting protection, which makes it a wise investment.

Factors Influencing Its Lifespan

Several factors can influence the lifespan of an EPDM roof, including the following:

Installation Quality 

Proper installation, including the proper flashing and sealant, is critical to the longevity of an EPDM roof. Improper installation can lead to leaks, damage, and a reduced lifespan.


Regular maintenance and cleaning can help extend the life of an EPDM roof. Part of the maintenance effort should involve regularly inspecting your commercial roof in order to keep the roof free of debris and address any minor damage promptly in order to prevent larger issues from arising. 


The weather in which an EPDM roof is installed can affect its lifespan. Extreme temperatures, heavy rainfall, and strong winds can also put additional stress on the roof, reducing its lifespan.

UV Exposure 

EPDM roofing is designed to resist UV light, but excessive exposure to the sun can still cause damage over time. Installing a reflective coating on the roof can help reduce UV exposure and extend its lifespan.


Like all roofing materials, an EPDM roof will face general wear and tear and wear out over the course of its lifespan. Even if your EPDM roof has met its 50-year mark and is still holding strong, you may want to consider replacing it sooner, rather than waiting for severe damage to occur. Even if the EPDM itself looks fine, other components may be damaged and hidden underneath that will affect your roofing system.

EPDM roofs are considered flat roofs due to their low slope and pitch. Read our blog post on how long a flat roof lasts to learn more.

Advantages And Disadvantages

Like all roofing materials, EPDM roofs also have advantages and disadvantages.

Durable: EPDM roofs are known for their durability and resistance to harsh weather conditions, and their ability to stand up against UV light.

Flexible: The flexibility of the material allows it to stretch or bend without cracking or breaking, making it ideal for flat or low-slope roofs.

Waterproof: The excellent waterproof properties of EPDM roofs protect a building and its contents from water damage.

Low Maintenance: EPDM roofs are low maintenance and easy to clean, which makes them a cost-effective option for homeowners and property owners.

Disadvantages of EPDM roofing

EPDM roofs are also prone to damage and deterioration over the years. Some of its disadvantages include: 

Limited Color Options: One of the disadvantages of EPDM roofs is that they are only available in black, which is a disadvantage to property owners who want to pair the color on a roof with the rest of a building’s exterior.

Susceptible To Ponding Water: EPDM roofs are susceptible to ponding water, which can cause damage if there is no adequate drainage system in place on your flat roof.

UV Degradation: Though EPDM is durable against UV rays, these rays are also one of the factors that decrease its lifespan due to excessive exposure.

Signs Of EPDM Roof Failure

In many cases, homeowners remain unaware of why their roof has started leaking, or why certain damage occurred to the roof. Many times this happens due to irregular maintenance and piled-up debris and dust on the roof. By maintaining your roof in a timely manner, you can identify the sources of leaks, or damage that may contribute to problems before it’s too late.

Cracking Or Splitting

One of the most common signs of EPDM roof failure is the cracking or splitting of the material. This occurs due to weather exposure, improper installation, or aging of the roofing material. If the cracks are not addressed promptly, they can allow water to penetrate the roof, causing further damage and reducing the lifespan of the roof.

Leaks Or Ponding Water

Leaks or ponding water can indicate that the EPDM roof is failing. Water can penetrate the roof through cracks or seams, causing damage to the building and its contents. Ponding water can also cause the roof to deteriorate more quickly, reducing its lifespan. 

Discolored Roofing Material

Faded or discolored material is another sign that an EPDM roof is failing. This can occur due to exposure to UV light, which causes the roofing material to degrade over time. If the roof is faded or discolored, it is a sign that it’s no longer providing adequate protection for the building, and it may be time to consider a roof replacement.

Maintenance And Repair For EPDM Roofs

Follow the procedures given below to maintain your roof.

Regular Inspection And Cleaning

Regular inspection and cleaning are important for maintaining the longevity and effectiveness of EPDM roofing. Inspection can help identify small damage before it becomes a bigger problem, and cleaning can prevent the buildup of debris and other materials that can cause damage to the roof.

Repair For Small Damages 

For small damages, such as cracks or tears, patching, and repair may be the best solution. This can be done by applying a patching material to the damaged area, which will help extend the lifespan of the roof.

Professional Replacement For Severe Damage

For severe damage, such as large cracks or widespread leaks, professional replacement may be necessary. This can help ensure that the roof is repaired properly and that it continues to provide adequate protection to the building. A professional roofing contractor can assess the damage and determine the best course of action, whether that be patching and repair, or full replacement.
