White Roof Coatings Will Lower Your Building’s Electrical Utility Bill

Posted by Nicole Gale on Thu, Mar 24, 2016 @ 08:00 AM

Asphalt.jpgElectrical utility companies use a pricing model called Critical Peak Pricing (CPP) where the cost per kilowatt-hour varies depending on the time of day. This pricing model charges a premium or higher rate during times of peak energy usage, such as during the hot afternoon in the summer.

White roof coatings provide an easy and cost effective way to reduce your building’s air conditioning usage, which will in turn, lower your electricity costs. Using a highly reflective, white roof coating redirects the sun’s heat away from the building, back into the atmosphere. This allows the building to remain cooler while absorbing only a minimal amount of heat into the structure.

There are several white roof coatings available in the roofing industry, it is important to research the reflective capabilities the coating is able to provide initially and at 3 years. The Cool Roof Rating Council (CRRC) tests and rates reflective roofing products to provide consultants and building owners with these initial and 3 year unbiased results.

National Coatings' reflective roof coatings have been tested and rated by the CRRC to prove and guarantee that our top coats provide industry leading UV protection, longevity and brightness. They are formulated for superior dirt pick-up resistance and protection against biological attack, such as algae and mold. For a list of our CRRC rated products, click here

Benefits of Installing White Roof Coatings to a Newly Constructed Roof

White roof coatings provide two excellent benefits for a newly constructed roof. The first is reduced heat load to the building if it does not already have a reflective roof and the second benefit is that white roof coatings extend the roof’s lifespan.                    

Reduced Heat Load

CLICK HERE TO FIND OUT: What's The Difference  Between "Cool Roof"  Versus A "Normal" Roof?White roof coatings are reflective; allowing the roof surface to reflect a majority of the sun’s heat caused by ultra violet (UV) radiation away from the rooftop, back into the atmosphere. The ability to reflect the bulk of the radiation allows only a minimal amount of the remaining heat to be transferred into the building below.

Most white roof coatings are able to reflect 80% or more of the sun’s heat compared to a black surfaced roof that absorbs the full amount of heat. Reflective coatings therefore provide a much cooler indoor climate without any air conditioning usage, while a black surface roof would heat the inside of the building at a faster rate, requiring the use of an air conditioning unit to provide a comfortable environment to tenants, employees and customers inside.

The reduced heat load to the inside of the building offers energy cooling savings and reduced HVAC usage. This can drastically reduce your energy utility bill, resulting in substantial savings throughout the year.

Extended Lifespan

Reflective roof coatings contain UV blocking ingredients that protect the surface of the roof from premature degradation. UV rays are the leading cause of roof damage as a result of excessive heating of the substrate caused by prolonged sun exposure, ultimately leading to a brittle and inflexible surface, eventually leading to water damage and other forms of roof degradation. White roof coatings protect the roof with its ability to reflect the damaging UV rays, allowing the lifespan of the roof to be extended beyond the roofs original life expectancy. This concept can be compared to sunblock on our skin. Sunblock protects our skin from premature aging and sun damage, while the lack of sunblock creates premature damage - wrinkles, sunburns, blisters and more. 

National Coatings strongly suggests the use of white roof coatings to protect your roof and lengthen its service life while reducing energy cooling costs.  For more information on roof coatings, download our FREE guide – Considering Coatings, a Free Guide to Roof Coatings.
