What is EPDM roofing? It’s a rubber roofing polymer shown to be durable, protect your home from the heat, and even reduce your energy bills.
According to RubyHome, about 29% of homeowners replaced their roofs due to a leak. However, another 25% anticipated their current roof to fail soon.
Knowing the right material to use helps prevent this from happening. Understanding the unique benefits of EPDM can help you decide if it’s the best option for you.
What Is EPDM Roofing?
What is EPDM roofing? EPDM stands for ethylene propylene diene monomer. It’s also called rubber roofing.
The material comes out in a single sheet. There are also several components underneath. These include the:
- Roof decking base
- Vapor barrier
- Insulation
- Cover board
Not all EPDM roofing is equally thick. There are several thickness options for different jobs and roofs. The most common ones include:
- 45-mil
- 60-mil
- 90-mil
EPDM flooring can be non-reinforced or scrim-reinforced. Certain types also have a fleece backing.
EPDM roofing is popular for both commercial and residential buildings. There are certain projects it’s particularly suited to, such as:
- Flat or low-slope roofs
- Re-roofing
- House extensions
- Sheds
- Green roofs
EDM Installation Process Options
There is no single EPDM installation process. There are actually three potential installation methods. Choosing the right one and hiring the right contractor to do it is the most important part of ensuring longevity.
Fully Adhered
The fully adhered method for EDPM roofing involves gluing the materials directly to the roof or insulation with adhesive.
It provides the strongest wind resistance and the best penetration prevention of all three installation methods. It also offers the best long-term performance and appearance.
The issue is that quality takes time and money. Fully adhered installations are more time-intensive and cost more.
Mechanically Fastened
Mechanically fastened EDPM installation involves fastening the sheets to the roof. It involves a combination of latches, fasteners, or screws.
This is one of the most common methods, especially for lighter buildings. It’s faster than the others because you don’t have to wait for the adhesive to cure.
Mechanically fastened EPDM roofing provides a healthy balance between cost and performance.
Ballasted
Ballasted installation of EDPM roofing involves laying the sheets out. Then, they’re kept in place or ballasted by gravel, stone, or sand. There are no anchors or adhesives needed.
This is the cheapest upfront installation option. However, it may require engineering approval. This adds extra time and money to the project.
Ballasting isn’t the best choice for homes in high-wind areas. It also makes it more difficult to inspect or repair the roof because the ballast must be moved.
Is EDPM Roofing Good?
One of the major EPDM roofing benefits is its durability. It prevents foot damage to commercial roofs and resists punctures and leaks.
It even stands up well to fire. This is essential for states like South Carolina, which Wildfire Risks to Communities says has around a 60% higher fire risk than other states.
EDPM roofing can protect you for years. It can even protect the planet after you’re done using it.
EPDM roofing is an environmentally friendly option for those concerned with sustainability. It’s easy to turn into a green roof. You can also recycle it when it’s no longer usable.
Another one of the major advantages of EPDM roofing is its cost-saving capabilities. According to SaveOnEnergy, South Carolina has one of the highest energy bills in the US. They average around $179.13 per month.
EPDM roofing can reduce your bills by regulating your heat. It’ll block UV radiation and put that heat back out, so your heating and cooling systems don’t have to work as hard. That added efficiency shows up in a lower bill.
EPDM roofing is one of the most cost-effective options available. The initial EPDM roofing cost may be high in terms of installation, but you’ll save money over time. You’ll rarely need expensive repairs, and maintenance needs are minimal.
Which Is Better, TPO or EDPM?
TPO is one of the newest competitors to EDPM, so comparing EPDM vs TPO roofing is important to get the best option for you.
EPDM roofing has been around for decades. TPO is a newer formulation without a proven track record.
It does have certain advantages, though. It resists punctures and foot traffic well. The heat-welded seams it uses can hold up better than EPDM’s tape and liquid adhesives.
The choice often comes down to the climate you live in.
TPO roofing works better in hotter climates because its white surface reflects more sunlight, providing additional energy savings. EPDM is better suited to colder climates. It’s flexible and can withstand temperature fluctuations without cracking.
Frequently Asked Questions
Is EDPM 100% Waterproof?
Yes, the EDPM membrane itself is completely resistant to water and UV radiation.
However, that doesn’t mean the roofing is invulnerable. Certain parts of the roof can be damaged over time.
The adhesive on the seams and joints can degrade. Puncturing the membrane to install mechanical fasteners can create leak points if they aren’t sealed. Prolonged pooling water can also cause weakness.
This is why you should regularly inspect it for signs of damage, especially after heavy storms. You should also get professional inspections to prevent minor damage from becoming severe.
How Long Will an EDPM Roof Last?
A survey by the EDPM Roofing Association brought roofing professionals together to address the longevity of EDPM roofs. They found that approximately 14% of EPDM roofs lasted up to 45 years, and around 26% lasted 35-45 years.
How long they last before needing to be replaced all depends on factors such as:
- Membrane thickness
- Installation quality
- Routine maintenance
