Is there a Difference between White Roof Paint and White Roof Coating?

YES! White roof paint does not have the durability, strength, protection, reflectivity, and waterproofing capabilities of a white roof coating.

Often time’s people refer to white roof coating, as white roof paint, when in fact, coating and paint are very different. White roof paint cannot withstand the typical elements a roof endures. It becomes brittle and will peal, chip and crack within a season. A white roof paint does not protect your roof from the sun’s heat by reflecting the sun’s UV rays away from the building or provide waterproofing. It was thought that they would provide energy savings being that they are white, however; because white roof paint cannot reflect the heat away, it does not add value to saving energy usage or costs.

White roof coatings contain high reflective pigments to ensure the sun’s heat is absorbed as little as possible. This allows the building to remain cooler, providing cost savings on energy consumption to cool the building.  The high reflective pigments in white roof coatings also lengthen the life span of the roof by reflecting the damaging UV rays away from the building instead of absorbing them. The sun’s UV rays are the leading cause of roof degradation because the intense heat breaks down and dries out ingredients that allow for the roof to expand and contract during weather and temperature fluctuations. Therefore, the highly reflective white roof coatings keep the roof from cracking, becoming brittle, and aging prematurely. The polymers used in a white roof coating allow for superior bondage to the existing roof membrane. This is necessary as it provides excellent waterproofing and ensures durability and protection to the roof and building below.

What is "Critical Peak Pricing?" How does it Relate to Roofing?

Posted by Nicole Gale on Thu, May 08, 2014 @ 11:00 AM
More specifically: How can electrical utility initiatives help me save money when I coat my roof white?

Critical Peak Pricing (CPP) is a pricing model used by electrical utilities where the cost per kilowatt-hour varies, depending on time of day.  Electricity peak demand times, usually in the afternoon in the summer, will be charged at a premium or higher rate than other times during a 24 hour period.  The term "net metering" is sometimes used to determine and record peak demand.   Electrical utility companies have begun installing "net meters" that calculate kilowatt usage during "peak demand" and "normal or low demand" periods.  This information is used to determine costs based on this two-tier pricing model. 

"So how does this relate to roofing?" If the user can reduce electrical usage, they will save money.  This can easily be accomplished by reducing air conditioning electricity usage.  A very easy and cost-efficient way to achieve this is to coat the building's roof with a white reflective roof coating

The roof life extension benefits of white reflective roof coatings have been well documented.  Now, the initiative described above offers even more of an incentive to coat your roofs white with National Coatings AcryShield roof coatings. Download our Roof Coating Systems brochure to find out more.

Roof Coatings - A Roofing Material that Saves You Money

Posted by Nicole Gale on Tue, May 06, 2014 @ 11:00 AM

Roofing Material Elastomeric roof coatings are excellent at sustaining and restoring existing aged or leaking roof membrane. All roofing materials require proper application and maintenance to perform to their fullest – roof coatings are no different. When applied and maintained properly, elastomeric roof coatings offer cost savings benefits by prolonging your roofs’ life and reducing energy costs and usage. 

Prolonged Roof Life

Elastomeric roof coatings are ideal for restoring and maintaining Asphalt roofing (BUR and Mod Bit), Single-Ply roofing (TPO, EPDM, PVC and Hypalon), Spray Foam roofing (SPF), Metal roofing and Concrete roofing.  The coating systems allow the roof to be renewed and restored – achieving a watertight, fully seamless, brand new roof membrane. AcryShield roof coating systems are the leading coating systems in the industry allowing you to restore your roof indefinitely. When proper roof maintenance is performed, a fully restored roof coating system can be re-coated every 10-15 years, allowing you to avoid a costly roof tear-off forever.

Reduced Energy Usage and Costs

Roof coatings with high Ultra-Violet (UV) blocking pigments are the best choice for a roofing material that needs to provide you with durability and protection from the sun’s harmful and damaging UV rays and heat.  Roof coatings containing large amounts of these UV blocking pigments allow the sun’s heat to be reflected back into the atmosphere (a process otherwise known as solar reflectance) without the building absorbing much of the heat (a process otherwise known as thermal emittance). This keeps the temperatures inside the building down. The greater ability to reflect the sun’s radiation, the cooler the building remains, and the less air conditioning is needed to create a comfortable temperature for the occupants inside. The Cool Roof Rating Council (CRRC), an organization that accurately and credibly evaluates solar reflectance and thermal emittance of roofing materials, has rated our AcryShield roofing products highly - check the ratings out! The AcryShield roof coating line has be proven to lower energy consumption and save on air conditioning costs. 

After the National Coatings' Cool Roof was installed we definitely noticed a difference in building temperature. It's not a marginal difference, either. It is between 15-20 degrees cooler inside the warehouse and store." Jerry Moore, Facilities Director at Harbor Freight Tools
