The Basics of EPDM Roof Repair

EPDM stands for ethylene propylene diene monomer. That’s a really long way of saying it’s a synthetic rubber. It became extremely popular due to its application in repairing roofs. EPDM roof repair provides many advantages over conventional methods. Keep reading to learn the basics of EPDM roof repair.

How Does It Work?

EPDM roof repair works by applying the rubber to any problem areas, providing a nearly impenetrable seal. Oftentimes, however, it’s simply used as a precaution—covering roofs before any damage can be done.

Once applied, EPDM forms an extremely durable layer of protection that is waterproof, amongst other things.

Applying EPDM to a Flat Roof

If you’re using an EPDM roof repair application for a flat-topped roof, you’ll first want to begin by cleaning the surface off. Many people use EPDM for the entire roof to work as a kind of sealant. In this scenario, the entire thing will need to be cleaned first.

While the climate is probably temperate if you’re working on a roof, it’s worth pointing out that it should be between 40 F and 70 F outside, otherwise you’ll have issues with applying the synthetic rubber.

Once the roof is cleaned, apply a primer. A paint brush is best for this job, but if you’re doing the entire roof, you’ll want to use a roller and an extension to make things easier.

With the primer applied, start in an area that won’t present any odd angles. You’ll want to handle all these areas first, as it’s simply easier to do. Odd corners can be addressed when you finish by cutting the sheets and applying them where need be.

Applying EPDM to a Conventional Home Roof

You can also utilize EPDM roof repair on a residential home, as well. However, you wouldn’t want to cover the whole thing as in the above example. You’d have to remove all the shingles first, if you truly wanted to. EPDM is just a good way to take care of a stubborn leak, especially if you’re worried it will begin to cause sloping issues for your roof.

Start off by finding exactly where the leak is coming from. Just as in the above example, you’ll want to clean off the area affected. Do this by removing all the shingles on and around the affected area. Depending on the size of the sheet you’re using, this may mean more shingles than are actually compromised.

Instead of using a primer, like above, you’ll apply a fiberglass enforced felt skin that works well with the adhesive qualities of EPDM. Then, use one fastener per 2 square feet on the installation. When using EPDM on a residential job, seams aren’t an issue, so you need not bother.

One of the best parts about fixing a roof with EPDM is how fast it sets. If you finish your job by the afternoon, it will be ready for a storm later that night. Due to its durability, you also shouldn’t have to address the problem again for about 20 years.
