An Overview of the Four Major Types of Roof Coating

Homeowners nowadays can choose from a wide variety of roof coatings and paints for their homes. Selecting a coating depends on a variety of factors including the material used, style and pitch of the roof.

Which one should you choose if you have an option? The information we provided below should help in your selection.

Acrylic Coatings

These are made of different kinds of acrylic polymer and manufactured to increase the durability of the coating and therefore extend its life. While different colors are available, they come mostly in white because of its reflective quality. Most people prefer acrylic coatings because of their durability and low price.

Proper application of acrylic coatings require at least two coats and may be rolled or sprayed. For best results, the second coating is applied perpendicular to the first. A recoating is also recommended within 2 to 3 years from application.

Asphalt Coatings

Another name for this type of coating is cutback coating. The asphalt component, which is solid at room temperature, is liquefied or “cut back” with the use of a solvent. The process makes it easier to apply the coating on the roof’s surface. Asphalt coatings are sold either in black color or reflective coating of aluminum-finish. Users are advised to observe caution because asphalt coatings usually contain asbestos.

Asphalt Emulsions

These contain different types of organic and inorganic fibers and other fillers that strengthens the coating. The primary component are asphalt particles diffused in water. Clay is used as the bonding element. Asphalt emulsions generally come in brown and black colors although reflective versions are available when titanium or aluminum are added to the mix.

People who prefer asphalt emulsions point to its easy application as a major factor. Applying the coating requires very minimal material and may be accomplished with the use of push broom.

Silicone Coatings

This type of coating is a favorite among environmentalists because it is biodegradable. Silicon coatings are created using solvents and catalyst added to a silicone base, a natural mineral. You can apply the coating using either a roller or spray gun. What make silicon coating stand out from the other types of coatings are its resistance to water ponding for long periods of time and its ability to adhere to different substrates even without the application of a primer. These two qualities of silicone coating make it the best type of coating since they produce both cost-effectiveness and quality.

Liquid RV Roof Coating Pros and Cons

Even the sturdiest RV roof will ultimately develop cracks and weaknesses due to prolonged exposure to extreme weather conditions.

To ensure that your RV’s roof remains in pristine condition, regular checkup and maintenance are necessary. In the event cracks develop on the roof, you can select from several RV rubber roof coating products available in the market. However, with so many roof repair products to choose from, people are expectedly confused on which ones deliver on their promise.

One of the well-known products in the market today is Liquid Roof RV roof coating. It is a liquid EPDM (Ethylene Propylene Diene Monomer), and therefore, possesses all the characteristics of EPDM when properly applied to the roof. When it cures, it offers the same advantages of an EPDM membrane, including flexibility and stability.

We reviewed the Liquid Roof RV roof coating and came up with its pros and cons. Here are what we found:


  1. Versatile. It can be applied to virtually any surface such as fiberglass, fabric, sheet rubber, plywood and metal with the use of a brush, roller or squeegee. Most people prefer squeegee while others opt for a combination of brush and roller.
  2. Convenient. The product becomes water proof instantly after application, although there is a required curing time. The best part is that only one application is needed for total protection. It also self-levels once applied, thus minimizing on labor hours. You have plenty of time to properly apply the product before it cures.
  3. Economical. One gallon of RV roof coating covers 40 to 46 square foot. It lowers interior temperature by reflecting sunlight with its white color, which means huge energy savings.
  4. Total Protection. The product is resistant to ozone and Ultraviolet rays from the sun. It can withstand freezing snow, alkalis, acids and salt water. It also prevents ponding of water on the roof that could lead to leaks.
  5. Durable and Flexible. Liquid Roof remains flexible and durable at temperatures between -60°F to 300°F. The coat sinks into every crack and crevice in the roof, ensuring a water-tight application.


If you buy a four-gallon container of the product, be sure to use it within a year from opening. Some people found the content separates into a rubbery top coat and white stuff underneath after some time. Others complain that applying the coat is slightly difficult because of its thickness.


The superior qualities and performance of Liquid Roof RV roof coating easily outweighs the very few apparent weaknesses of the product. In truth, these are not flaws that affect the quality of the product but merely the result of its improper use.
