Elastomeric Roof Coating Explained

With all the advantages out there when it comes to roof coating, it’s understandable that you may want more information before making a decision. Your roof is important, after all, so anything but the best is taking a pretty big gamble. Keep reading to learn more about one option, an elastomeric roof coating.

What is an Elastomeric Roof Coating?

An elastomeric roof coating is one that greatly resembles rubber once it’s applied. One of the main advantages of this particular form of coating is that it can be applied to so many different kinds of roofs.

What are Its Advantages?

There are many benefits to choosing an elastomeric roof coating. As mentioned above, it can be used on just about any surface type. This includes roofs made out of metal, single-ply applications, built-up applications, modified bitumen, and much more. It can even be applied to freshly sprayed polyurethane foam.

The actual angle of the roof doesn’t matter, either. Unlike some other coatings that can only be used on buildings with a flat top, elastomeric coatings can handle those and ones with just about any type of slant to them.

Once applied, an elastomeric roof coating will provide superior resistance against just about any weather condition. As it acts much like rubber, it can stretch when the temperature goes up and then retreat to its original shape when it gets colder out. By doing this, it resists cracking.

Because of the strong seal this coating produces, it’s great for energy efficiency. Cold air and heat stay in, while the outside world is kept at bay.

There are four main types of elastomeric coating. They are as follows:

Acrylic Elastomeric Coating

This is the most widely used elastomeric roof coating. It’s great for roofs with a positive slope, for one thing. It also displays superior longevity and is easy to clean. Furthermore, many people appreciate that it is considered an environmentally friendly option.

Butyl Elastomeric

For flat roofs or those with a low slope, butyl elastomeric is a great choice. It works especially well on roofs that are made from modified bitumen, asphalt built-up, or singleplied roofing. One advantage for flat roofs is that this variety can resist the pressure of pooling water.

Polyurethane Elastomeric

While EPDM roof coatings are considered high quality, adding a polyurethane elastomeric coating will further help ensure the roof’s overall protection. This variety is also especially good for roofs made from modified bitumen or a single-ply application of PVC or TPO.

Silicone Elastomeric Coatings

This is a great option for a roof that was recently treated with polyurethane foam. The main reason is that a silicone elastomeric coating displays excellent weathering. Whether the foam was just recently sprayed or needs a new layer for protection, this is a great choice.

When you’re looking to coat your roof for added protection, it’s hard to think of a better option than the rubber-like elastomeric coating. It can be applied to just about any surface, and it will display excellent durability while adapting to weather conditions. With several different options to choose from, you can find the coating that will work best for your roof.

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.

Keep in mind that the above advantages are contingent on quality installation. While many people may be successful in installing EPDM on their own, they take the results into their own hands. Many of the benefits listed above will not be a factor if installation is mishandled.

When it comes to putting a roof over your head, you’d be hard pressed to find a better option than EPDM rubber. For added savings, incredible durability, and little-to-no maintenance issues, EPDM roof coatings will deliver. Best of all, you won’t have to think about it again for decades to come.

Why You Should Opt for Liquid Rubber?

You should opt for liquid rubber as it is a very useful, efficient and unique matter which has been used as a roofing solution with tremendous success. It was originally created by Kuraray Co. Ltd. in 1972 as a thick, viscous liquid which is derived from butadiene, isoprene and/or styrene. It is transparent and odorless. One of the primary uses is that it is used at a “Reactive Plasticizer”. It comes in liquid form and when used, it cures to form a hard and sturdy surface holding almost any required shape. It is successfully used for a variety of purposes, ranging from toys which are molded to useful roofing solutions.

Liquid Rubber Application

Liquid Rubber Application

Liquid rubber has been specially used all over the North America for over 20 years, in places and areas where extreme temperature spikes and fluctuations is a norm. It is very easy to use and an extremely productive seamless waterproof membrane. Due to its special characteristics, it can easily meet most of the health, safety and environmental requirements, and therefore provides great industrial and commercial benefits.

Applying liquid rubber is a simple, hassle-free and safe process. You can apply it on the required surface area using a brush and roller which is more appropriate for small scale residential projects. The large scale projects, for which you can use it, include factory or warehouse roofing which uses a spray system. It can be sprayed on the required surface area and this method can be used to cover up to a thousand square meters in a single day. This method is generally referred to as “Instant Set”, and it does exactly what the name suggests – the liquid rubber takes the required shape naturally and instantly, giving you instant waterproofing. Since the rubber that is sprayed is cold, it also eliminates any potential fire hazards, and it forms itself quickly as singular and seamless membrane. Since this method does not require the usage of any fleeces or primers, this method of roofing has proved to be up to five times faster than many other comparable roofing solutions.

Its unique composition gives its users an astonishing elasticity of up to 1100% along with a startling memory of 95%. It is almost unparalleled when used as a roofing solution on roofs which are expected to face excessive movements.

Application of EPDM Roofing Materials

This roofing solution provides similar advantages to that of EPDM roofing solution – it offers protection against ozone and heat, as well as provides good resistance against polar substances and steam. Additionally, liquid rubber roof is also resistant to water, salt and alkalis. It also gives a smooth, crease-free surface, and is easy to apply. The only issue with this type of roofing is that you cannot directly apply it to asphalt roofs or asphalt shingles. You need to first apply a coat of acrylic solution on which the liquid rubber can then set itself.

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.

Easy Ways to Avoid Costly Forms of RV Roof Repair

No one wants to spend the time and energy on getting their RV’s roof repaired. But you’d never know it, judging by how some people treat their vehicles. If you don’t take the necessary steps along the way, RV roof repair will become inevitable. Continue reading to learn some simple things you can do to make sure that your RV doesn’t end up needing constant repairs to its roof.

Safety First
Before you ever do anything involving your RV’s roof, be sure you check the owner’s manual. You’ll want to be well informed about how much weight it can carry. Even if you’re well below the maximum amount that it mentions in the manual, it’s best not to spend any more time on top of your RV than you absolutely need to. The fact that you can see damage has been done means that there could be more elsewhere. Take the wrong step, and all of a sudden you could need professional help for your RV roof repair.

Inspect It Regularly
If you aren’t constantly looking, it can be easy to forget how much abuse your RV’s roof takes. From tree sap to rain to debris and much more, your RV is constantly being exposed to issues that could easily result in its roof needing repairs.

So the first step in avoiding RV roof repair costs is inspecting the roof every 3 to 4 months. If it stays parked under trees for prolonged periods of time, you’ll want to do this more often. Otherwise, you risk issues like algae and mold building up. Be sure that the seams get a close inspection every 6 months, as well.

This means checking the inside, too. Just because you don’t notice any issues from the outside, that doesn’t mean your RV isn’t in trouble. Water stains on the ceiling or towards the top of the walls are reliable signs that something has gone wrong.

Clean Regularly
Inspecting your RV’s roof is important, but so is keeping it nice and clean on a regular basis. Oftentimes, you can’t see the beginning of a problem forming, but cleaning your RV’s roof is a big step in stopping that issue in its tracks. Always be sure that you’re using products that have been specifically made for RVs.

Handle the Issue on Your Own
Sometimes, no matter what you do, problems arise. Fortunately, if it’s a leak, many will fall under the kinds of RV roof repairs that an amateur can handle on their own. You can save a lot of money this way, too. So, if you notice a leak, be sure to address it as soon as possible. Just like with cleaning supplies, though, you’ll want to make sure that you only use products that were made for an RV. For example, if you have a leak, you’ll want to use a sealant. Plenty are made for actual shingle-and-tar roofs, but that will only make matters worse in this scenario.

Fortunately, if your RV springs a leak, there’s plenty you can do to handle the matter on your own. Most people would like to avoid any RV roof repair with Liquid Roof as much as possible. As such, follow the above advice, and your roof will be less likely to need your help.
