Our AcryShield® asphalt roof coating systems have been successfully used to protect and prolong Built-Up (BUR), Modified Bitumen or Mod Bit and Asphalt roofs since the early 1980's. The coatings in these systems are specially designed to resist water infiltration, bleed through effects of exposed asphalt, and UV degradation. Our systems specialize in high reflectivity and emissivity allowing them to create a cool roof surface which protects your roof from the rigors of the hot sun. These Cool Roof Systems prolong the lifespan of your roof and provide a cooler environment inside the building with less HVAC usage, ultimately lowering your energy cooling costs.
Applying an
AcryShield Roof Management (ARM) System,
AcryPly Roof Restoration System, or
AcryShield SPF Roofing System to renew or restore your aged BUR, Modified Bitumen or Asphalt roof can be done with little disruption during installation (allowing your business to remain open during application) and with almost no VOC contaminants or fumes during the process. Many of our asphalt roof coating products contain
ZERO VOC's or ultra low VOC's. The renewal and restoration process can be done several times without having to tear your roof off, allowing you to eliminate the need for a costly tear off indefinitely. These asphalt roof coating systems create a truly sustainable solution for your failing roof.
Wondering How Asphalt Roofs Wear Out?
Asphalt and modified bitumen deteriorate because of two environmental factors: ultra-violet radiation and heat from the sun. Consider a simple analogy where a piece of thin gauge sheet metal is constantly bent back and forth until it cracks. The same happens on a molecular level by the UV damaging the bonds of the asphalt molecules. The degradation process is accelerated by the heat from the sun, as heat makes chemical reactions happen faster. The heat also causes the "light fractions", liquid asphalt components that act as plasticizers, to leach out making the resulting material more brittle.
You Can Protect Your Asphalt Roof
Protecting your roof against the sun's damaging UV rays and heat can prevent asphalt deterioration. This is why one of the three Cool Roof Coating Systems mentioned above are recommended: AcryShield Roof Management (ARM) System, AcryPly Roofing System or AcryShield SPF Roofing System over the asphalt based product. Our AcryShield A503 base coat is ideal for asphalt because it is a one component, waterborne coating with unique wet adhesion properties specifically designed to asphalt, allowing for superior protection against ponded water and eliminating the need for a costly roof replacement. National Coatings has several top coats for asphalt roofing that contain unique properties to solve your buildings exact needs. These top coats offer a wide range of benefits including: bleed-blocking capabilities; coatings for areas where extra levels of low temperature flexibility are required (areas that drop below 0˚F); zero VOCs; ultra high reflectivity; excellent tensile strength, elongation and wet adhesion; and products that exceed all ASTM D6083 requirements.
Roof life can be greatly extended by protecting the asphalt, modified bitumen or BUR by using National Coatings' AcryShield products. The earlier the roof is coated in its service life, the longer the roof lifespan and the lower the life cycle costs will be.
