There are several different types of materials used to build roofs. From shingles to flashing, roofing professionals must be familiar with common roofing materials.
In this blog post, we’ll cover EPDM rubber, which is a common choice for roof membranes. Here’s everything roofers should know about EPDM roofing material. Let’s jump in.
What Does EPDM Stand for?
While EPDM may sound like a cool new type of electronic dance music (EDM), it actually is a useful material commonly used in construction.
EPDM stands for ethylene propylene diene terpolymer. It’s a bit of a mouthful, so most folks call it EPDM instead. EPDM is a durable type of synthetic rubber that can be used for roof membranes. It’s designed to last for the long haul.
Unlike natural rubber, EPDM rubber can handle exposure to extreme conditions like sunlight and ozone. Natural rubber tends to break down over time and become fragile.
In addition to roofing membranes, EPDM is also commonly used in the automotive and HVAC industries, as well as in many home appliances.
EPDM Roofing Installation
EPDM’s flexible properties make it fairly easy to install on roofs. It’s typically quick and efficient to install, which can help cut down on labor costs. Since EPDM can be installed over existing roofing materials, it’s a top choice for reroofing projects.
That said, installation difficulty will differ depending on your skill and experience level. EPDM roof installation is typically considered easy for skilled contractors but is not recommended for homeowners to DIY themselves.
EPDM is a material better suited for flat roofs than pitched roofs. Since water won’t run off low-pitched or flat roofs, it’s important to use waterproof materials on these types of roofs.
EPDM Roofing Vs. TPO
TPO, thermoplastic polyolefin, is another material used for flat roof membranes. It’s known for its cost-effectiveness and flexibility.
When comparing EPDM and TPO, there are a few key points to consider.
Aesthetic
While this is subjective and unique to everyone, the different materials provide a different look for roofs.
Reflectiveness
TPO is usually white and, therefore, is highly reflective. It’s usually the better option for those prioritizing energy efficiency in extremely hot areas. EPDM, which is typically black, absorbs more heat.
However, in cooler climates, EPDM’s heat absorbency can decrease heating costs. Both materials are available in multiple colors. White EPDM can increase its reflectivity and help lower cooling costs in hotter climates.
Here’s an example of available TPO color choices and EPDM color options.
Durability
While both materials are widely considered to be very durable, TPO roofs generally don’t last as long as EPDM roofs. This difference is due to EPDM’s high resistance to UV and extreme temperatures.
However, TPO roofs tend to have higher resistance to punctures.
Cost
Both TPO and EPDM are known for being cost-effective roof choices. The exact cost will vary depending on several factors. However, EPDM tends to be a little more affordable than TPO.
According to Rainville-Carlson, EPDM typically is in the range of $4 to $8 per square foot. On average, TPO roofs cost between $5.50 and $9.50 per square foot.
Invest in the Right Materials and Tools for Your Business
While EPDM roofs have some drawbacks, they also have numerous benefits. Their durability, easy installation, and cost-effectiveness make EPDM a smart choice for certain roof jobs.
