Tips to Getting the Most Out of EPDM Rubber

Whether you’re reroofing your business or your home, or you’re trying to find a way to create a unique fish pond without using a plastic liner, EPDM rubber should be your material of choice. It’s easy to apply, is watertight when fully cured, and offers a wide range of benefits. Unlike other types of rubber, it’s even safe for fish. However, there are things you’ll need to know in order to get the most out of this material. We’ll cover some important tips below.

EPDM Rubber Installation Tips

We’ll start with installation tips to help ensure that you get a good, even coating of EPDM rubber and that it goes on smooth and easy.

Use the Right Tools: You can use a wide range of tools to apply EPDM rubber, but two of the most commonly used and most helpful are paint rollers and sprayers. Rollers allow you to apply an even coating across a roof (or other surface) with ease. We recommend longer handles for easier application, too. Sprayers are also very convenient, particularly for very large roofs and hard to reach areas where a roller or brush might not fit very easily.

One Coat Is Enough: If you’ve spent much time painting, then you’re probably thinking that EPDM rubber will need more than one coat in order to withstand weathering and to look good. That’s usually not the case. In most situations, a single coat will be more than enough. Too many coats will add excess weight to your roof and will also adversely affect curing time.

Waterproof: While many products require curing time before they are waterproof, that is not the case with EPDM rubber. It’s actually waterproof after just a few minutes. However, don’t equate waterproof with fully cured. It will take roughly a week for the coating to completely cure in optimal temperatures and humidity ranges.

Extend the Lifespan

Once applied, you need to ensure that your EPDM rubber coating will stand the test of time. A few basic tips will help you extend its lifespan.

Maintain It: There’s very little that you need to do in the way of maintenance for EPDM rubber, but there are a few things that will help ensure you get the best longevity possible. Twice per year, you should inspect the area. Look for signs of damage or possible leaks. In most cases, minor repairs can be made by simply applying another coat of rubber over the damage. In addition to your visual inspection, you’ll need to remove debris from the area, as well. These can form dams that cause water to back up, and can even help foster mold and mildew growth.

Flashing and Edging: During your inspections, pay close attention to any flashing or edging. If these come loose or are damaged, it could lead to damage of the rubber coating. If you’re required to replace edging or flashing, make sure that the membrane is turned down over the fascia with the metal cover installed over the top.

In Conclusion

EPDM rubber is highly durable and can be used in a very wide range of situations, from commercial roofs to waterproofing in basements. It’s economical, incredibly durable, and readily available. However, like any other product, there are things you need to know to get the most out of it. The information above will help you maximize the lifespan of your rubber application, enjoy ease of installation, and prevent leaks that might damage the substrate under the rubber coating.

EPDM vs PVC: What’s Right for Your Roofing Needs?

If you are the owner of a flat-roofed or low-slope roof structure, you already know that your roofing needs are far different from those with buildings featuring traditional, more steeply sloped rooftops. Your roofing has to be resistant to everything from extremes of temperatures and the risks of pooling water, snow and ice to structural movement. This is why the issue of EPDM vs PVC so frequently emerges.

Why the EPDM vs. PVC Issue?

You will see a lot of EPDM vs PVC comparisons when you start to search for roofing because these are the two most commonly chosen materials for flat roofs. EPDM is a rubber material made mostly with oil based ingredients. PVC is a vinyl-like material made of chlorine and ethylene.

Are there pros and cons to each? Absolutely, and it is imperative to run that EPDM vs PVC comparison as you narrow down your choices for your new or replacement roof on a flat-top or low slope building. Let’s start with the EPDM and its many pros and cons.

EPDM vs. PVC: The Pros and Cons of EPDM

Ethylene propylene diene monomer or EPDM is a synthetic rubber and is treated with a range of chemicals to help stabilize the material and make it long-lasting, flexible and durable. Typically, EPDM is UV stable, meaning that it can be exposed for many years to the intense powers of sunlight without degrading or breaking down. It is also able to withstand extremes in weather such as incredibly hot summers and intensely cold winters without turning brittle or breaking down.

EPDM is able to flex enough to support structural movement, too. And perhaps one of the most important “pros” for the EPDM roofing is the fact that there is no special equipment or skill needed to install it. It does ask for a great deal of prep in terms of cleaning and/or installing a new roof decking on which the material is applied. However, with good brushes, rollers and patience even a novice can do a good job.

Lastly, it is the most affordable type of single-ply membrane-style roofing and has been in use for decades.

EPDM vs. PVC: The Pros and Cons of PVC

A more recent innovation in single-ply, membrane-style roofing is PVC roofing. However, one of the major “pros” of the PVC roofing is that it is actually made of three layers of material that feature PVC material reinforced with polyester “scrim” between. It is, however, described as a single-ply membrane. This means it is considered a bit more flexible and stable with high break and tear resistance. It is identical to EPDM in that it has UV resistance and can remain stable under extremes of heat or cold. PVC is also quite resistant to fire and chemicals, and typically inhibits the growth of any fungi or plant materials.

And also just like EPDM, the PVC materials are designed to be watertight and leak free for many decades after installation. This material also requires attention to prep when it is installed, and it requires “hot air welded seams” rather than an adhesive to bond together properly. This is why the PVC roofing is also a job for professionals who know how to handle the machines and materials properly.

This tends to boost the price of a installation, making EPDM the lower priced option with the added benefit of a DIY installation if desired.

In the debate of EPDM vs. PVC we now know that PVC is just as durable but requires experts to install the material properly. If you are looking for a long-lasting, easy to install and affordable roofing material for a flat roof, the EPDM materials may be the ideal choice.

What Are the EPDM Roof Advantages?

As a property owner, it is natural for you to weigh the various pros and cons for any materials or systems you use on that property. Whether it is a commercial building or a residential property, you want to be sure your investments give you the returns you desire. Those returns can usually be summed up (no matter what sort of project) as long-lasting, good looking, high performing, low maintenance and affordable. All of these terms apply to the list of EPDM roof advantages, as well.

What is EPDM Roofing?

EPDM is ethylene propylene diene terpolymer, an oil-based rubber roofing option that is a long-lasting and popular choice. This is because it does exactly what a property owner hopes a roofing material will do – remain watertight and effective for many years. Naturally, there are more EPDM roof advantages than the simple fact that it is an effective option for a rooftop.

For one thing, one of the most significant EPDM roof advantages is that the material can work well on perfectly flat or low-sloped roofs. Whether it is a commercial building with a lot of venting and other issues on the flat roof or a residential structure with a very low slope or pitch to the roof, EPDM is a good option.

Flat or low-slope roofing always has more trouble because it can so easily succumb to issues like intense weather (heat or cold), pooling, structural changes, and roof traffic. Thus, the EPDM roof advantages are very significant when deciding on what materials to use for your low-slope or flat roof.

A Basic List of EPDM Roof Advantages

So, just what are the EPDM roof advantages apart from its watertight properties and durability? The advantages include:

DIY – If you would prefer to tackle the project yourself, EPDM can be installed by a novice who is willing to purchase the simple tools needed for installation AND take the time to do the prep work essential to a good outcome. This may mean installing new plywood or panels for the material to bond to, performing an intense cleaning of the entire surface, and so on.

Affordability – Of the many materials available for flat and low-slope rooftops, EPDM is the most affordable among them. Not only can it be done by you or with a group of friends, but the materials themselves are affordably priced and considered the lowest priced among all other similar options.

Longevity – An EPDM installation will have a lifespan of 50 years or more (if cared for properly and installed correctly). It will ask for little to no maintenance and even with any issues, repairs are easy, inexpensive and fast to perform. The material resists UV damage, flexes with the building’s movement over time, and all without weakening or degrading.

Safe – EPDM materials are fire resistant, which is important as they are often exposed to intense amounts of heat and light, and if a nearby building or fire puts your property at risk, it is often noted that EPDM may slow or impede the movement of a fire.

Greener – One of the best advantages to using EPDM is that it is easily one of the “greenest” materials. It requires very little energy to produce and when you need to replace it (50 years later) the materials are 100% recyclable! You won’t even need to use heating machines to install them, meaning they ask for no energy to install.

So, if you are eager to find a roofing material with a great many advantages and few “cons” to its use, EPDM is a good choice.
