The Essentials of Properly Applying An EPDM Rubber Roof Coating

A lot of work goes into maintaining a building. Most new commercial building owners are unaware about just how many different systems they will have to keep up with when attempting to keep their investment in good shape. Taking the time to get to know the vital systems in a commercial building can help to save an owner a lot of time and trouble. The roofing system on a commercial building can come in many forms. If the roof is flat, then chances are that the roofing will be made of EPDM rubber. The best way to offer this rubberized material the protection that it needs is by applying a specialized EPDM rubber roof coating. There are a number of different types of coatings out there and finding the right one can be made a lot easier by speaking with a professional in the EPDM industry. Applying the roof coating is not easy and will require a number of considerations to be made.

Cleaning the Roof is Essential

The first thing that has to happen when trying to get the EPDM rubber roof coating applied the right way is the cleaning of the roof surface. Over time, the rubber membrane on a flat roof will acquire a lot of dirt and grime. The roofing professionals that are hired to perform this type of work will use a specialized cleaning solution to mop up the dirt and grime off of the surface. By working on one section of the roof at a time, the professionals will be able to get the surface clean and puddle free in no time at all.

Repairing All Damage Present on the Roof

Before the EPDM rubber roof coating can be applied to a roof, the professionals will have to do a thorough inspection to determine if there is any damage. If there is damage found, the professionals will have to get it fixed. Neglecting to fix holes or tears in the rubber membrane will usually lead to issues down the line when the coating begins to wear off. The time and money that the business owner invests into getting these repairs is worth it. The professionals will also be able to address any ponding issues that may be present on the issues by applying a liberal amount of sealant to fill in the dip that this type of condition causes.

Rolling the Sealant On

Once all of the prep work has been done, the professionals will be able to start rolling on the EPDM rubber roof coating. In order for this sealant to do its job, the professionals will have to work a section at a time getting a thick coating applied. The last thing that a commercial building owner needs to do is to try and apply this coating on their own. Attempting to do a DIY EPDM rubber roof coating job will usually end in mistakes that can cause long-term problems for a commercial building owner.

Getting the right professionals hired for this type of work is an essential part of getting the job done right. Be sure to call around to a few different roofing professionals in an area to get an idea of what each of them can offer.

How to Decide What Type of EPDM Rubber Roof Coating is The Best Fit

A commercial building is a very big investment and will require a bit commitment from the owner. When owning this type of building, a person will be responsible for all of the maintenance and repair issues that arise. One of the best ways to maintain an EPDM roof is by choosing a quality coating for it. The coatings on the market will actually act as the top layer of the roofing, which can help to prevent damage to the actual rubber membrane. Most commercial building owners fail to realize that there are a variety of different EPDM rubber roof coating materials out there. Choosing the right one will require the commercial building owner to get familiar with the options that they have and decide which is the best fit for their needs.

An Acrylic Based Coating

Among the most common types of EPDM Rubber roof coating used by professionals is an acrylic based variety. These types of covering are water-based, which is great for the environment and very cost effective. In most cases, this type of coating will be used in hotter areas due to the cool down effect that it has. This reflective material will help to reduce the amount of heat the roof absorbs, as well as limit the damage that can be caused by UV rays.

Polyurethane Roof Coatings

The next type of EPDM rubber roof coating available to a commercial building owner is made of a polyurethane base. This type of coating is generally used by commercial building owners that are in areas prone to damaging winds. The polyurethane is used to create a more durable surface that is able to withstand higher winds. In most cases, this type of coating is used near the flashings of the roof. By placing this coating on the flashing, a commercial building owner will be able to protect against damages that may cause leaks.

Silicone Roof Coating

Adding a silicone EPDM rubber roof coating can help a commercial building owner avoid damages caused by extreme temperature. This type of coating provides a very slick surface and can be applied in multiple layers. The more layers of silicone based coating a commercial building owner has on their roof, the more durable it will ultimately make it. By talking things over with a roofing professional, the building owner will be able to figure out how many coats of this silicone based covering they need to adequately protect their roofing. The professionals will be able to weigh a variety of different factors regarding the roofing on a building in order to make the right recommendations. Failing to apply enough of this silicone based coating will leave an EPDM roof exposed to the elements.

The time and energy that goes into choosing the right EPDM rubber roof coating will pay off. The right coating will allow a commercial building owner to avoid serious repair issues that are caused by lack of protection on the rubber membrane of their roofing.

The Advantages of EPDM Roof Coatings

There’s no getting around the importance a roof plays in any structure. Whether it be a home, a warehouse, office building, etc. you need a strong roof that can provide shelter from the elements. Leaks do happen, however, at which point, you want to act fast to solve the problem. Despite all the options available, you can’t do much better than having EPDM roof coatings above your head. Keep reading to learn why applying EPDM to your roof is one of the best decisions you can make for the structure.

Immune to Most Climates:

EPDM roof coatings can handle just about any climate condition short of a tornado. They can withstand low temperatures all the way down to -40 F without cracking or becoming brittle.

If you live in the Southern Hemisphere, you’ll be glad to know that a roof covered in EPDM doesn’t mind the warmth, either. While temperatures will never get up to 300 F, EPDM has shown it wouldn’t be a problem if it did.

The really great thing about EPDM roof coatings, when it comes to climate, is how much it can save you in energy costs. EPDM gets a lot of credit for keeping the elements out, but the truth is that it does just as good a job keeping your cold air or heat in, where it belongs.

Repair and Maintenance:

As the above attests, a roof covered in EPDM will have an easy time withstanding the elements. Yet EPDM needs very little, if any, maintenance. While you’ll want to clean your roof periodically, simply to keep things like fungi or algae from growing, the synthetic rubber itself won’t need any help.

This also provides greater savings. The longer you can go without having to fix your roof again, the more of a return you’re getting on your investment. But this can also provide great savings for use on an office building. As that type of building constantly undergoes inspections for worker safety, you won’t have to worry about spending more to keep it up to code.


It’s hard to think of another option that can provide the kind of longevity you’ll get from installing EPDM Roof coatings. The ERA (EPDM Roofing Association) recently conducted a study. In it, they examined a number of EPDM roof coatings that were 30 years old. Their finding was that, even after 3 decades, the EPDM maintained a high degree of tensile strength, almost as if it were new.

Why EPDM For Your Roof?

EPDM (ethylene propylene diene monomer) is one of the ways through which you can ensure that you have safe and proper roofing. This roofing solution has been in use for over 50 years, and therefore boasts proven performance record. EPDM has proven itself to be a long term roofing solution with studies indicating that it can provide protection for more than 40 years.

The two main elements of EPDM, ethylene and propylene are derived from gas and oil. They are used for a variety of purposes, ranging from radiators and tubing to vibrators and solar panels. Although it is generally used in vehicles, it has proven to be a highly effective and practical roofing solution. It is a reliable resilient synthetic rubber roofing membrane and mainly used on low-sloped buildings and flat roofs all across the world. This is primarily due to its extremely high resistance towards weather, ozone and heat. It also has excellent electrical insulation properties and offers protection from steam and polar objects. They tend to come in both black and white colors and can be of various lengths ranging from seven to fifty feet, while its thickness is either 45mm or 60mm.

Generally, installing EPDM roofing is a safe and simple process as it does not require the use of any heavy machinery. It comes as a single, lightweight ply membrane. It is cut and tailored according to the requirements. Since it is made from high quality polymer, it costs less as opposed to other roofing solutions. Due to the fact that it is a lightweight material, the labor cost is also significantly reduced.

EPDM roof once installed requires little or no maintenance. It is very easy to repair these roofs and even costs less to do the annual maintenance. It is an extremely sturdy material, and yet it boasts an unusually superior flexibility in comparison with other similar materials. Due to the fact that the material is rubbery, it is highly durable and greatly resistant against abrasion and tear.

With many similar rubbery roofing solutions, you might have to seam together multiple pieces of “sheets” which can expose the risks of water accumulation, damp and all types of related issues. This is a problem which is eliminated by the fact that it comes in a block which is generally sufficient to cover almost any roof. Most suppliers provide roughly twenty years of guarantee with a life expectancy over 50 years – it is clear that EPDM is more than up to the task of protecting almost all roofs for a significant length of time. Furthermore, you must also know that EPDM helps with lower insurance premiums. Not only that, it is also a friend to the environment, as it has limited environmental impacts in comparison with some of its rivals.

Liquid EPDM Coatings are aftermarket roof sealants

A number of aftermarket roof sealants are available, including urethanes, acrylics and liquid rubber. Liquid EPDM rubber is by far the most durable of the sealants available and has the widest range of applications.

It is more water resistant than other rubbers, including neoprene. It is more resistant to swelling and has a wider range of acceptable temperatures. It can be applied directly to practically any roofing material other than asphalt and can even be used on wood that has been primed.

Liquids have an obvious advantage over sheets. Sheets have seams. Seam sealers eventually deteriorate and water gets through the seams and under the sheeting.

Liquid EPDM can be used on top of neoprene, although some pre-treatment of the surface is required. Just knowing that the liquid rubber is recommended for use on top of the other type of rubber should be an indication that the material is more durable.

Liquid EPDM can also be used on top of polyurethane after a light sanding. It is somewhat surprising that urethanes are still used as aftermarket roof sealants. It is known that the structure is damaged by UV light and that discoloration occurs relatively quickly. Anyone who has made the mistake of using urethane as a roof sealant should consider applying liquid EPDM to truly protect the roof.

The liquids can also be used to seal existing leaks. They are self-adhering and fill up tiny fractures that let water through. It is a good idea to use a thick coat and cover the entire surface instead of attempting to only cover the leaky area.

When covering the entire roof, the liquid rubber reduces heat buildup. Not only does the roof stay cooler, but the interior of the building or the vehicle will also stay cooler. This benefit may reduce heating costs and keep the occupants more comfortable.

Liquid EPDM has become the most popular choice for RV roofs, because of all the above-mentioned advantages. It extends the lifespan of the roof and requires less maintenance. It lasts up to three times longer than any other aftermarket RV camper rubber roof sealant and also reduces noise from rain.

As far as price goes, most sealants are similar in price. Depending on where you buy, EPDM may be a little more expensive, but because primers and additional coats are not usually necessary, and because it lasts so much longer, owners who choose this aftermarket roof sealant save money in the long run.
