If you are considering a new roofing material for your home, you may be wondering how to apply an elastomeric roof coating. Here are some tips to make the process as simple as possible:


One of the benefits of an elastomeric roof coating is its ease of repair. Instead of tearing down the entire roof and scraping off the old coating, a small team can quickly repair a damaged elastomeric roof. Because elastomerics are monolithic and weather-resistant, repairs take much less time than with conventional roofing systems. To maximize the benefits of elastomeric roofing, you must ensure that the material is flexible enough to adjust to extreme weather.

Applying an elastomeric roof coating should be done on a day when the temperature is mild, since residual moisture may affect the coating’s adhesion and integrity. It is best to apply the coating when the weather forecast calls for no precipitation for several days or a minimum of 24 hours. While cold temperatures can cause the coating to fail, bright, sunny conditions will help it dry quicker.


The cost of applying an elastomeric roof coating varies based on the type of coating used. You can expect to pay approximately $14 to $20 per square foot, plus the cost of building permits and tools. Urethane coatings can be anywhere from $40 to $65 per square foot. The application process will require tools such as all-purpose brushes, push brooms, and solid plastic core roller covers. A power drill with a mixing device and sprayer equipment are also required.

The lifespan of elastomeric roof coatings can be anywhere from 10 to 20 years, depending on its thickness. Some sources quote longer lifetimes. The cost of applying an elastomeric roof coating will pay for itself within the first year or so, as long as the coating is properly installed and maintained. Often, the coating will even save you money in the long run. Additionally, it is not disruptive to the day-to-day operations of your business.


The durability of an elastomeric roof coating is determined by the amount of time it remains unaltered by sunlight and weathering. These conditions are artificially accelerated using ASTM methods. As a result, the reported value is often a maximum number of hours before cracking occurs. Fortunately, this number doesn’t really represent how long the coating will remain intact, but it is a good indication of its durability.

In general, an elastomeric roof coating will last anywhere from 10 to 20 years, but some sources quote even longer. The exact lifespan will depend on the thickness of the coating, how much maintenance it receives, and how well it is installed. However, it is important to consider the overall lifespan of the roof coating to get the most benefit. The thicker the coating, the longer it will last. For a 10-year warranty, you should seek out an experienced roofing contractor.


The application of elastomeric roof coatings is a simple process, but good results require a high level of care and attention to detail. Using an airless sprayer with a minimum working pressure of 3,000 PSI is essential. It is also important to prepare the roof prior to application. The roof must be clean, dry, and structurally sound. To avoid problems, the roof should be well ventilated and dry before coating.

Elastomeric roof coatings are flexible and can be applied to almost any type of roofing system. They can help reduce wear caused by the weather elements, protect from ultraviolet rays, and can increase the lifespan of the roof by up to 20 years. The best part about elastomeric roof coatings is that they are very easy to maintain. Fortunately, they are easy to re-seal after a couple of years and can be reused for as long as the roof is still in good condition.
