Property owners willing to install an EPDM roof often wonder how long it will last. The lifespan of an EPDM roofing system isn’t a one-size-fits-all answer, it largely depends on many factors, which we will take a closer look at in this blog post.
In order to understand the lifespan of an EPDM roof, you need to first understand its properties and material composition, which ultimately make up its durability and longevity.
A Comment On The Longevity Of An EPDM Roof
An EPDM roof can last between 30 and 50 years, all thanks to its material composition and great properties. However, the lifespan of EPDM roofs largely depends on many factors, including installation and maintenance. If your EPDM roof isn’t installed correctly, or you forget to keep up with its maintenance, the EPDM roof will deteriorate quicker than expected. Therefore, it is important to consider all the factors that affect its lifespan and durability prior to installation.
Understanding EPDM
There is no doubt that the innovation of EPDM back in the 1950s led to the development of an all-new roofing system. With the creation of EPDM, there was a new, durable, sustainable, and weather-resistant roofing material that could last longer than other materials at the time.
EPDM is short for Ethylene Propylene Diene Monomer and falls into the class of synthetic rubber, which differs greatly from natural rubbers in terms of heat and weather resistance. It can handle temperature extremes ranging from -49°F to 300°F without being affected. This means that the material has a high resistance to thermal movement, which can prevent various forms of damage compared to other alternatives.
EPDM is also incredibly durable and stays firm and intact in high winds and storms. Hail has a minimal effect on its surface and the material is also resistant to UV rays. All these properties combine to make EPDM a studier, thicker, more durable, longer-lasting, and weather-resistant commercial roofing material.
The Lifespan Of An EPDM Roof Compared To Other Roofing Membranes
Here’s a breakdown of the different lifespans for different flat roofing materials so you can see how EPDM compares to its alternatives.
- EPDM generally lasts 30 to 40 years, with some well-maintained installations lasting up to 50 years.
- TPO has a lifespan of about 15 to 20 years, with advancements pushing this closer to 25 years.
- PVC can last between 20 to 30 years, with some high-quality installations reaching up to 35 years.
- Modified Bitumen generally lasts between 10 to 20 years, with high-quality systems potentially lasting up to 25 years.

Factors That Affect The Lifespan Of An EPDM Roof
While EPDM rubber roofs are naturally durable and last for many years, certain factors can affect their durability, leading to a shorter, or longer, lifespan. So, it is important to consider all these factors in order to maximize the lifespan of your EPDM roofing system.
1. Quality of Installation
If you want to install an EPDM roof on your commercial property, the most important thing to keep in mind is that regardless of the membranes’ thickness and durability, installation is everything.
There are generally three methods of installing an EPDM roof: fully adhered, ballasted, and mechanical fastening, all requiring attention to detail and careful techniques. Failure to adhere to specific installation guidelines for EPDM results in premature damage and a reduced lifespan.

2. Regular Maintenance Practices
After the quality of the installation, most roofing problems occur due to infrequent, or no maintenance at all. Without actively assessing your roof regularly and repairing minor forms of damage when found, your roof will not last as long as your home, requiring replacement sooner rather than later.
3. Membrane Thickness
The thickness of the EPDM roofing membrane is another important factor in how long your roof will last. Thicker membranes are highly regarded as more resistant to the weather, making them the most sought-after choice on the market. In general, EPDM membranes come in different thicknesses, such as 45, 60, or 90 mils, each offering different levels of durability and resistance to punctures and tears. Always choose the appropriate thickness based on the specific requirements of the building and the local climate in order to enhance the roof’s performance and longevity.
4. Roof Design And Structure
EPDM is typically installed on flat roofs, which due to their design, typically experience ponding water and require additional drainage systems and gutters in order to protect the roofing material. A well-designed slope ensures that water flows off the roof efficiently, reducing the risk of water damage. Moreover, features such as vents and skylights create potential weak points in the roofing membrane. Therefore, it is super important to address these areas when installing an EPDM roof.
5. Foot Traffic And Usage
The amount of foot traffic and how the roof is used can impact its longevity. High amounts of foot traffic can cause physical damage to the membrane, such as punctures and abrasions, which can lead to leaks and a reduced lifespan. Installing protective walkways minimizes damage from foot traffic, especially in areas where maintenance workers frequently access the roof.
6. Chemical Exposure
While EPDM is naturally resistant to the effects of chemicals, excessive exposure to certain chemicals, such as oils or solvents, can cause damage. Preventing this type of exposure is key to maintaining the roof’s integrity. For instance, roofs near industrial areas or chemical plants might be more prone to chemical exposure, calling for additional protective measures.
