“Global Model Confirms: Cool Roofs Can Offset Carbon Dioxide Emissions and Mitigate Global Warming” was the News Release from the Berkeley Laboratories in July 19, 2010. There were more studies written up proving the same effect of cool roofs not only for the building owners and occupants but GLOBALLY.
What it was referring to is the “white” reflective roof membranes that are widely replacing the dark colored roofings of the past. What could possibly be the importance and effect of “white and reflective” coatings on roofs nowadays?
A dark colored roof absorbs so much heat that flows not only into the space below it but also back into the atmosphere thereby causing an urban warming or heat island effect. On the other hand, a white roof reflects sun’s rays and thereby absorbs much less heat, requires less energy from air conditioning thereby getting its name “COOL” roof. A cool roof is “a gift that keeps on giving for many, many years, for the life of the roof” as expressed by the researcher Hashem Akbari of The Lawrence Berkeley National Laboratory whose work was also supported by the California Energy Commission (CEC).
National Coatings Corporation’s AcryShield Roof Maintenance (ARM), AcryPly Roof Restoration and AcryShield SPF Roofing Systems are excellent reflective roofing systems in that they have superior watertight capabilities and they are renewable indefinitely. Choosing any of those systems would allow you to avoid a costly and time consuming roof tear-off forever.
Lowered Air Conditioning and Cooling Costs
AcryShield coatings can save you as much as 20% or more in cooling costs. A reflective roof membrane has the capability to reflect the sun’s UV and infrared rays away from the building, allowing the roof temperature to increase only by 12oF which is much lower than the 78oF increase from the traditional black roof. With a lower temperature increase of the cooler roof is a reduced heat transferred to the insides of the building. This relates to a significant reduction in electrical energy demand for air conditioning. It also relates to the increased comfort of anyone in the building. "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.” This is the testimonial of Jerry Moore, Facilities Director at Harbor Freight Tools. Harbor Freight Tools had an AcryPly Roof Restoration System installed on their aging and severely leaking roof at their corporate headquarters. He was very impressed and pleased with the new system.
Reduced Roof Maintenance
A high performance reflective roof membrane has high quality UV blocking ingredients in order to protect your roof from the leading causes of roof degradation - sun damage from UV and Infrared rays. Not only does the high reflectivity lower air temperature inside the building but also by reflecting a majority of the damaging UV rays away from the surface of the roof, the roof is protected from cracking, splitting, weathering and ultimately from leaking. National Coatings has several highly reflective roof coatings that can be applied over almost any roofing substrate.

Prolong the Lifespan of your Roof
AcrySheild reflective roof membranes not only lower the roof life cycle costs by making the roof last longer but also extend the tear-off date indefinitely. Our AcryPly Roof Restoration System is unlike a traditional roof in that it is a spray applied, monolithic, coating system that can be applied directly over your leaking and aging roof. This system costs up to 50-70% less money than replacing your roof. With it is an added value of being able to re-coat your roof every 10 or so years, giving you a new, watertight, reflective roof membrane with half the cost and time a tear-off would take.
