Does Color Matter When it comes to Reflectivity of Roof Coatings?

Posted by Nicole Gale on Thu, Jul 02, 2015 @ 11:00 AM

031_borderThe short answer is, yes! White roof coatings provide the greatest reflectivity values available; however, that is not to say that other colors are not able to provide you with ideal reflectivity.

Highly reflective roof coatings are full of UV blocking pigments that provide your roof with protection against premature degradation caused by the sun’s heat. The greater amount of reflectivity the coating can provide, the longer your rooftop will survive. The added protection against the sun’s harsh elements can lower roof maintenance costs, lower energy consumption, extend the life of roof top mounted equipment and easily extend the roof’s lifespan. While roof coatings come in a large range of colors, choosing the whitest and brightest coating will provide you with the greatest reflectivity and protection to your roof.

Need Help? Contact a Roofing  Professional  Zero ObligationNational Coatings has four standard roof coating colors – white, sand, light gray and dark gray (we can also custom color match most any color necessary to meet your needs); however, of these four standard colors, white is our most popular as it provides our customers with the greatest reflectivity benefits. If you take a look at our roof coatings that are tested and rated by the Cool Roof Rating Council (CRRC), you will see our AcryShield A510 has an initial solar reflectance of 0.84 in white and 0.72 in sand. This is true with any of the other coatings that come in multiple colors; the white roof coating is always the most reflective.

Another factor to consider aside from color is, dirt pick-up resistance. Dirt pickup resistance is defined as having the ability to maintain it’s white color and appearance even after the roof has come in contact with dirt, dust, and other outside environmental conditions that could darken the surface. Long-term success of the coating you ultimately choose for your roof will greatly influence the cost savings and benefits you will gain. The CRRC is a great resource, as it not only provides initial testing but also 3-year, aged testing to determine the long-term reflective capabilities of the coating.  

National Coatings’ products are engineered to achieve success in regards to high reflectivity capabilities. The AcryShield roof coating line is packed with more UV blocking pigments, is richer in performance ingredients, contains excellent dirt pickup resistance and provides some of the highest reflective roof coatings available to the roofing industry. The AcryShield Ultra High Reflectance A590 coating, for instance, has an initial solar reflectance of 0.92 and 3-year, aged solar reflectance of 0.87 - the aged, 3-year result is higher than most roof coatings can provide initially.

What is Reflective Roof Paint?

Posted by Nicole Gale on Tue, Mar 10, 2015 @ 11:30 AM

reglazing-windows-10Reflective roof paint is actually not paint. The proper terminology is “reflective roof coating”. While roof coatings resemble paint, they are much more durable and the thickness and strength is unmatched to what paint is capable of.

At first look, paint can be mistaken for a roof coating because it has the same viscosity and the application is similar – both can be brushed, sprayed, or rolled on. However, reflective roof paint would not provide the following benefits a reflective roof coating delivers:

  • Resistance to Ponded Water
  • Reflectivity Properties
  • Flexible at Low Temperatures
  • Ability to Expand and Contract with the Buildings Movement
  • Resistance to Foot Traffic

Reflective roof coatings are designed to be installed on a horizontal surface, such as a low-sloped roof, tolerating many external stresses and having contact with water for extended periods of time. Reflective roof paint would not possess the ability to be a protectant to your roof or be used as a waterproofing mechanism to your building. Roof coatings protect the building from water penetration during wet weather, dew, fog, and ponded water situations. The coating is able to repel the water, absorbing none of it into the roof substrate below. These coatings are tough enough to be walked on when roof maintenance and equipment on the roof top needs to be serviced. Roof coating systems have a required mil thickness that provides strength and durability, offering adequate protection to the roof’s surface. The thickness also allows for the membrane to expand and contract sufficiently, without cracking or splitting. This flexibility allows the roof to move with the building during different temperature fluctuations.

Click me The next biggest difference between a paint and a roof coating is a roof coating has the ability and ingredients to reflect the sun’s heat away from the building, blocking UV rays from being absorbed into the structure. This allows the building and roof to remain at a cooler temperature, reducing air conditioning usage and cost and reducing roof degradation and deterioration, enabling it to last longer. 

There are many different roof coatings available, some are tougher and more durable and others are better at reflecting the harmful heat from the sun. We have a list of different organizations on our website that offer unbiased tests and ratings for you to research, to determine and guarantee you are getting the best roof coating product that meets your needs.

Depending on the type of roof your building has, we have a solution for you! The AcryShield product line can adhere to the following substrates no matter whether it is a new roof or an aged roof in need of restoration:

  • Asphalt – Including BUR, Mod Bit and
  • Single-Plies – Including EPDM, Hypalon, PVC, and TPO 
  • Spray Polyurethane Foam (SPF)
  • Metal
  • Concrete
  • Wood
