A Basic EPDM Roofing Guide

If you are considering a new or replacement roof for a low-slope or flat rooftop, you already know that EPDM is the most commonly used material. Affordable, long-lasting and amazingly easy to install, it can be a DIY project or something done by those without any prior roofing experience. In this EPDM roofing guide, however, we are going to look at the different steps required and any “must know” information that can help make your EPDM installation a success.

The Steps to Installation

The first thing we must address in this EPDM roofing guide is the simple fact that any EPDM installation has to start with prep work. Without adequate preparations, your end result may be unsuccessful or less efficient – i.e. your rooftop might eventually leak or it is covered with ripples and bulges, etc.

So, step one in any EPDM roofing guide is to do proper roof deck preparation. That begins with cleaning the roof surface and making sure it is totally free of debris, dirt and dust, and oil or grease. You also must inspect it for any loose materials or spots where moisture lingers. Trapped moisture will ruin the installation, so be sure everything is clean and dry. Also be sure it is a material appropriate for the use of EPDM.

In fact, it is common for a EPDM roofing guide to skip a discussion of this key point. However, you must know what the materials can and cannot bond with effectively, and the most commonly suggested material is a timber deck that is OSB3 or exterior grade plywood.

Structural Issues to Know About

Though any EPDM roofing guide will tell you that installation of EPDM is easy, you still need to be aware of a few terms that might be unfamiliar to a novice. These include:

  • Drip batten – At the edge of a flat roof, and overhanging the gutter slightly, this is a durable board that you may have to install if not already present. It ensures that any water runoff reaches the gutters and does not drip behind the gutter
  • Back drip trim – This is a piece of molding that goes over the drip batten and is impervious to water and weather. It makes proper drainage a certainty
  • Chasing out – If you have an area of rooftop in which the roof adjoins to another material, such as brick and mortar, you need to use a chisel or grinder to “chase out” the joint and ensure that the flashing can adhere fully and properly
  • Mastic – This is the material applied to any wall trim areas like those discussed in “chasing out”. You will use this to bond and seal the edges and then also use simple tools to chase out the mastic or binding agent into the groove
  • Pig’s ear – This is a way of forming and folding the area of overhang at the edge of the roof. You will definitely want to practice this in advance of your first installation as it ensures that the membrane (EPDM material) makes an impervious and long lasting cover for the edges of the roof
  • Sweeping – When you have placed the adhesive and the EPDM rolls, you must then sweep the membrane and ensure any and all trapped air is swept out and from beneath as this insures bonding and prevents damage

This is just the basics and if you opt for EPDM roofing, you’ll want to invest in an actual step-by-step EPDM roofing guide that walks you through all of the preparatory steps, the different processes needed for installation, and all of the unique methods you will have to know to finish the roof and get a good seal for years to come.

Top EPDM Roof Advantages

EPDM is one of the most popular types of roofing systems in use today. It can work well for businesses that have flat or low-sloped roofs, but it can also work for residences and outbuildings with these types of roofs. What is it about this type of system that makes it so popular? You will find that there are many EPDM roof advantages that can provide your roof with the protection it needs.

Fewer Seams Provide Better Coverage

The membrane sheets tend to come in large, wide rolls. This means that they will have fewer seams than other types of roofing materials. Fewer seams mean there will be less risk of an issue with those seams, such as leaks.

Quick to Install

While you will likely want to have a professional take care of the installation, one of the other EPDM roof advantages is the ease of installation. The contractors should be able to get your roof completed in far less time than it would take to install other types of roofing systems. This means less hassle for you.


The membranes are also lightweight compared with other roofing options, such as asphalt. This means there will be less weight on the roof, and it means that getting the materials up onto the roof for installation will be easier. It will also mean that your roof is under less stress than it would be with other types of roofing materials.

Potential Energy Savings

One of the EPDM roof advantages that many people never consider is the energy savings that can be had. This type of material comes in black or white. Since the roof is exposed to the sunlight throughout the day, this can affect how warm the building below gets.

Those who live in environments where it is often hot will want to use white EPDM, as this can reflect some of the light, keeping it cooler. It could mean that you use your AC less. If you are in an environment where you have cold winters, having black EPDM roofing can help to absorb the light from the sun and keep the building warmer, potentially reducing heating costs.

Highly Durable and Long Lasting

Of course, another one of the main reasons to consider using EPDM roofing is because of the durability. It can stand up to the weather and changes in the temperature very well. It won’t start to melt in high temperatures, as you might find with asphalt. It also has the potential to last for decades without needing replacement. If there are any minor issues that occur with the roofing, it tends to be very easy to repair without needing to replace the entire roof.

The Cost

One of the biggest advantages to this type of roofing is the cost. It happens to be the least expensive roofing system that you can install per square foot. The national average for the square foot price, before labor is added, is between $0.80 and $1.60. When compared with other options, you will save more when you use EPDM.

It Has Maintained a Good Reputation for Decades

This type of material has been on the market for a long time, and it has been able to retain its good reputation. It is a time-tested material that you can rely on to help keep your roof as safe as possible.

Of course, these are just some of the biggest EPDM roof advantages. If you would like to have this type of roofing installed, you can see why it can be a great option.

What You Need to Know About EPDM Roofing

EPDM, or Ethylene Propylene Diene Monomer, is very popular today when it comes to roofing, and it could be a good solution for your needs. It can work well with many different types of roofs, and you will find several EPDM options available to provide your roof with the added protection it needs. The material has been around since the 1960s, and it has proven to be very effective in a variety of capacities, not just for roofing.

Options With EPDM

The rubber is available in sheets in a range of thicknesses, vulcanized and nonvulcanized membranes, and as a liquid coating that can be applied similar to paint. The roofing material has become very popular with commercial roofs, as many businesses tend to have flat or low-sloped roofs. With so many options available, different types of buildings and buildings of different sizes can make use of the material.

It’s Environmentally Friendly

Those who live in environments where it gets cold in the winter months and who have relatively short or mild summers may want to choose the black coating. This can help to absorb sunlight and will keep the heating bills down in the winter. In addition, those who live in hot environments, such as the southern part of the United States, will find that the white coatings can help to reflect the heat. This keeps the cooling bills down.

Other Benefits of Choosing EPDM

As you start to learn more about EPDM roofing, you will find there are quite a few other benefits it offers. The material has the capacity to resist massive temperature fluctuations. It can expand and contract with the changing temperatures without any breaks or cracks in the material. It can last for up to 50 years when it is installed properly, and it is fire resistant. It is recyclable, and as you will see below, it tends to be easy to install.

One of the other benefits of the material is the fact that it is inexpensive. When you consider some of the other roofing systems out there that do not boast all of the benefits that EPDM offers, it’s amazing to see just how affordable the product can be. Even those who have large roofs can save a substantial amount of money when they choose the material.

Self-Installation or Professional Installation?

When you decide to go forward and get an EPDM roof, you will want to consider whether you will take care of the application on your own or hire a professional. For those who are choosing the large EPDM sheets that need to be applied, it tends to be much easier to have the professionals take care of the entire process. For those who are using a liquid EPDM instead, it might be possible to take care of the application on your own. This will depend on the size of the roof, along with your comfort in a DIY project like this.

Regardless of who installs the roofing system, you will find that it tends to be a relatively fast process. In very little time, you can have the peace of mind you need for your roof, and you will know that it can last for decades to come.

How to Maintain the EPDM Roof on your RV

If you maintain it well, an RV EPDM roof might last for more than 20 years… just about the working life of your vehicle. Even better, EPDM roofing materials require minimal care and maintenance to keep them in top condition. You only need a little bit of maintenance to keep them in great condition.

Regularly cleaning your EPDM Coatings Liquid Roof is the first step. You should clean it four times a year, using a cleaner specially designed for EPDM roofs that contains no petroleum distillates.

Why no petroleum-based cleaners? Whether the product is meant for protecting or for cleaning, any petroleum distillates in your cleaner will cause swelling and loosening of the rubber. Unfortunately, there are many products out there that will cause problems with your roof. The best idea is to find one that says on its label that it’s petroleum distillate-free and EPDM safe.

Once you start cleaning, you’ll find it’s pretty easy. Just stay safe as you do it, and keep on your hands and knees while you’re up on the roof in order to make sure you don’t fall.

Start by rinsing off your EPDM roof using plain water under pressure. If you can, remove any branches or other sharp objects by hand. EPDM is resistant to tears, but a sharp object may create scratches if it’s dragged along the roof surface. These scratches can turn into tears over time.

Having rinsed away all the debris, you can get up on the roof with a medium bristle brush and a bucket of EPDM-safe cleaner diluted with water. You only have to scrub the areas where you see dirt or stains. Bring your hose up too, so that you can rinse off the roof while you clean.

A tip: by starting in the corner furthest away from where you’re going to exit the roof, you’ll spend less time on the wet surface. You’ll also be able to scrub away any footprints you might leave, helping ensure your EPDM roof is absolutely spotless when you’re done.

Once you’re done cleaning, an EPDM protectant (not just any protectant, it must be designed for EPDM roofs) can help extend your roof’s useful life, minimizing the chances you’ll have to repair or restore it. Even if it is helpful, a protectant is not necessary.

Finally, properly caring for your RV’s EPDM roof means parking your RV in a place where the roof is as protected as it can be. Like with everything, the more your RV is exposed to the elements, the more problems that can occur.

Avoid parking around fruit trees, because they drip citric acid that can slowly deteriorate the EPDM material. The citric acid from fruit and fruit trees drips onto the roof and remains there until your next cleaning session. Over time, it penetrates into the rubber and reduces EPDM’s ability to resist the elements. If you do have to park where overhanging fruit is unavoidable, just wash your RV roof as soon as possible afterwards. A short term exposure is not likely to do much damage to your roof.

Why Choose EPDM Roof

EPDM has been the market leader for both low-slope and flat roof applications for more than 50 years. It is manufactured from oils, carbon black, zinc oxide, curing agents and polymers to enhance the membrane strength, durability and elasticity. The main polymers are ethylene, propylene and a small amount of diene. The common EPDM roofing materials provide a black finish, though some include dyes or pigments to provide a smooth white finish. The white finish helps the roofs to reflect back the sun rays and keeps the interior of the building cooler.

Continued QC (Quality Control) testing results prove that EPDM has the capacity to withstand the various climatic effects well beyond 30-years. Freeze/Thaw-Cycling (large and rapid fluctuations in temperature) is one of the most damaging environmental conditions roofing materials will face. EPDM is one of the very few materials proven to hold-up under such damaging conditions. In Northern America, EPDM accounts for over 52% roofing installations.

EPDM Roof Installation

EPDM roof installers may use one of the three installation methods – Ballasted, Mechanically fastened and Fully adhered. Because of its excellent flexibility, EPDM can be installed in any surface regardless of its shape, size and design. It can also be patched quite easily when damaged by tears or punctures. Also, it does not rely on plasticizers for its flexibility, so there is no danger of becoming brittle because of plasticizer loss in the long run. During installation, rubber is bonded at the seams to create continuous barrier. This allows EPDM-roofing to keep water from seeping into the roof structure and walls. Moreover, EPDM allows for ‘year-round’ installation because of its stability over a wide range of temperatures.

Benefits of EPDM

Even with the arrival of more technologically advanced roofing materials such as TPO and PVC membrane, EPDM has managed to maintain its advantages over other materials. Here is a list of the few key benefits of installing EPDM roof material.

• Easy to install
• Greater resistance to wind, water, and cyclic membrane fatigue
• High resistance to abrasion, weathering and ozone.
• Flexibility in even very low temperatures
• Resistance to extreme heat
• Thermal shock durability
• Restoration friendly
• Long life expectancies
• Ultraviolet radiation resistance
• Easier to install penetrations when needed
• Low maintenance required

There’s no question that EPDM holds its own advantage in service life, environmental sustainability and overall performance. EPDM has gained the popularity in the roofing industry since early1970s and will continue to be an affordable, dependable as well as efficient roofing solution for several years to come.
