Liquid EPDM Rubber 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 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.

1)       Catalyst must be added prior to use.  Scrape sides of container with a Liquid rubber spatula to ensure catalyst distribution.
2)       Xylene or Mineral Spirits Solvents may be added to adjust viscosity or for clean-up. 
3)       Easiest way to spread the rubber on a flat surface is to broadcast material with a rubber squeegee then roll using a short nap roller.  Product is self leveling.  A flat spatula can be used for small areas. 
4)       Product has a long pot life after catalyst has been added; 4-6 hrs. depending on temperature. 
5)       Only temperature affects the rate of cure.  Relative humidity has no influence. 
6)       Product is hydrophobic (sheds water) so substrate to be coated must be dry initially.  The uncured rubber can get wet or even have ponding water, with only a cosmetic effect after application, and will still cure.
7)       The rubber will penetrate into porous substrates such as wood and poured concrete.  A primer/sealer should precede application of rubber. 
8)       The chemical reaction of the catalyzed rubber can be arrested by freezing the material.  This can keep material usable for weeks or months.  To use again simply allow it to reach room temperature and apply.

Liquid EPDM vs. Other Roofing Materials

When compared to other roofing materials and sealants, Liquid EPDM may seem more expensive. As it turns out, the other materials will cost you more in the long run. Here’s why.

Liquid EPDM is identical to the older sheet EPDM rubber that was often used in roofing to waterproof and protect the underlying timber or other materials. The primary disadvantage of the sheet type is that there are seams. Even when seam-sealers are used, rain and temperature eventually cracks the seams. If the damage is not caught early enough, leaks are the outcome.

Liquid EPDM rubber is seamless. It is self-adhering. So, there is no need to use adhesives or fasteners, which are a source of corrosion and leakage. The liquid can also be used on any shape or angle.

Other liquids and sheets are now available, but none last as long as EPDM. It is resistant to tearing, ozone, abrasion and temperature changes.

The other liquid sealants require the use of primers, multiple coats and top coatings. EPDM is a one-coat system that does not require primers. That’s the first way that your overall cost is reduced. You don’t have to buy the primers and you don’t have to use multiple coats.

Another way that you save money has to do with repair and replacement. The initial EPDM coating can be applied three times as thick as neoprene and other elastomers. In side by side comparisons, the EPDM last three times as long as those other materials. It is also superior to acrylics and urethanes.

When compared to neoprene, which is an older elastomer that is less expensive, EPDM has a wider temperature range. It can withstand temperatures as low as 40 degrees and as high as 300 degrees without cracking, swelling or bubbling. Neoprene’s temperature range is from 60 degrees to 250.

The biggest “temperature” disadvantage of neoprene is that it cracks during cold winters, especially if ice builds up on the roof. This is not usually a problem with EPDM, because the temperature inside of the building will usually keep the roof temperature at or above freezing. It’s still a good idea to remove ice build-up, just to be on the safe side.

Neoprene is also less resistant to water damage and swelling. When you have to replace or repair something frequently, you can see how the costs add up. You’ll find that liquid EPDM really pays for itself as the years go by. With a 25 year history of success, you simply can’t go wrong with liquid EPDM.

Proper care of an RV EPDM roof and maintenance of RV roof

How to Maintain Your RV EPDM Roof

With proper care and maintenance, your RV EPDM roof can last for 20 years or more. That’s pretty much equivalent to the life of the vehicle itself. One of the benefits of EPDM roofing materials is that the care and maintenance required is minimal. Regular cleaning is the first step.

 Most manufacturers recommend cleaning the roof at least four times per year. The cleaner used should be one that is specifically designed for EPDM roofing and is free of petroleum distillates.

 Products containing petroleum distillates, whether they are designed for cleaning or protecting, will cause the rubber to swell and loosen. There are many chemicals that fall under the category. The easiest way to tell for sure that the cleaner you are using does not contain any of the chemicals is to look for one that states on the label “free of petroleum distillates, safe for use on EPDM materials.”

Cleaning is a relatively simple matter, but you should keep your safety in mind. If you are going to be getting up on the roof, you should be on your hands and knees to reduce your risk of falling.

 The first step is to rinse the roof thoroughly with plain water at a relatively high pressure. Any branches or sharp objects should be removed by hand, if possible. While EPDM is tear resistant, sharp objects can cause scratches when they are pushed along the surface. Eventually the scratches can become tears. Once all debris has been rinsed away, you will need to take a medium bristle brush, a bucket of safe cleanser diluted with water and get up on the roof. You need only scrub in areas where you see stains or dirt. Keep your hose with you so that you can rinse while you are cleaning. Start in the corner farthest away from your exit point and work backwards to minimize the amount of time you spend on the wet surface.

After the roof is cleaned, you can use an EPDM protectant if you like. The protectant should be specifically designed for EPDM roofing, not for other types of materials. Some EPDM manufacturers also sell special protectants. While using the protectant is not essential, it may extend the life of the roof and reduce your need to restore or repair the roofing material. Finally, proper care of your EPDM roof includes parking it in an area where the roof is protected as much as possible. Don’t park around fruit trees. The citric acid can deteriorate the material in between cleanings.

Roof is the most important element of the home construction

When we get tired of the whole day’s activities our most imperative want becomes to go home and get relax. As the thought of going home comes to our mind a smile comes to our faces unconsciously because of a peaceful place for tranquil. Home is the place which gives soothing and comfortable thought to everyone. It serves as a shelter from all the outside and environmental harms. Roof is the most important element of the home construction and its most intricate thing to repair and re-roof. Before deciding on roof repair or repair decision, all of us must be aware of the expected roof lives.

All roofs are made from different materials and each type of roof has a different lifespan. The best way to determine how long you can expect your roof to last is to check with the manufacturer’s warranty. However, you should also realize that with a preventive roof maintenance plan that utilizes seasonal inspections, you could greatly enhance the lifespan of your roof. When considering roofing materials, always talk with your roofer about the steps that you should take to maintain its condition as well as anything that you should do to ensure that you don’t void the warranty. By taking the time to choose the best roofing materials for your house’s design, structure and geographical location, you will have a better chance of enjoying new roof for many years.

Why Choose the Liquids?

Ease of application is one reason. The foil is more difficult to apply correctly. You could easily end up with bumps, overlaps and uneven spots that contribute to water pooling. Water can seep under the rubber sheets and cause the roofs to leak. So, while the rolls were the best choice for waterproofing at one time, there are better choices today.

 The liquids have more uses. They can be used on RV roof repair and other vehicles. They can be applied to a wide range of roofing materials including metal, fiberglass and wood. Through the use of an undercoating, the liquids can be applied to built-up and asphalt-based coatings.

Keep your roof from leaking with Liquid EPDM

Roof leak repair doesn’t have to be scary. There are tough roofs to work on no doubt. Attempting roof repairing on a steep slate roof repair should be left to the professionals. The same is true for metal roof repair or even tile roof repair. These are tricky materials to work with. But you should be able to successfully do home roof repair if you have a low-slope roof, a cool day and the right attitude.

The most important factor in any roof repair job is which contractor you choose. A good roofing contractor will check the area surrounding the leak in your roof for any sort of water damage. They should be able to let you know whether or not there is rot or water damage present, and whether or not it's bad enough to need repair immediately. In today's economy, cost is another important factor for roof repairs. There are many types of roofs here in Miami, and each type is going to have a different price range for repairs depending upon supply cost and availability of experienced contractors.

The cost of roof coatings is typically about 50% of that of re-roofing and the benefits are very tangible;

·         substantial reduced cost over re-roof
·         reduction in cooling costs with 80% reflectivity
·         years of longevity given to the existing roof
·         minimal disruption to the work environment during its application
·         minimal waste going to landfill
·         annual reduction in cooling costs as high as 22%
·         no toxic odours or vapours
·         ease of future repairs
·         no increase in roof weight load
·         reduced long term maintenance and roof repair costs

Roofs may need replacing for several reasons. It may be leaking and be more economical to replace rather than repair it. The roof may not be working correctly or does not look good. Another reason for replacing the roof may be because you are extending your home and want the roof to look fully uniform.

Several factors come into play and impact consultants’ decisions regarding the end of a roof system’s useful life. Thermal bridging, proper drainage, R-value, surface color, wind uplift, and hail resistance are all important factors to consider. When every¬ thing is taken into account, consultants are faced with two primary choices when addressing an aged Liquid EPDM roof besides a complete tear off and replacement: restora¬tion and re-cover.
