3 Elements Commercial Roofing Systems Need to Possess and Roof Coating Can Provide

  1. Weatherproofing
    All commercial roofing systems need to provide your building with resistance and durability to the effects of harsh weather conditions – primarily rain. After several years of exposure to the sun’s heat, the roof slowly breaks-down and loses its weatherproofing capabilities. Its flexibility begins to fail, and the roof starts to crack and split, eventually leading to leaks in your roof. To maintain proper weatherproofing for virtually any low-slope commercial roofing substrate, it is recommended that a roof coating restoration or maintenance system be installed. These commercial roofing systems are spray applied directly over your existing roof providing fully renewed, weatherproofing and waterproofing to your existing roof without adding a new roof substrate or investing in a costly and timely roof tear-off.  These systems are liquid applied, creating a monolithic, seamless membrane across your rooftop - filling any cracks, holes and voids that could cause leaks.
  1. Reinforcement
    Reinforcement is necessary for strength and durability to any commercial roofing systems. Using the AcryPly Roof Restoration system, a full layer of 100% polyester stitch-bonded fabric is embedded into the roof coating system to cover the entire roof field. This provides outstanding physical strength, unique elongation, and long-term durability to the roof structure. If your building only requires minimal reinforcement, the AcryShield Roof Management System (ARM) provides these same benefits in localized, problem areas only. Both these systems are installed without any business closures and with very minimal disruption to your building as there are no harsh odors or fumes (many of our products even contain ZERO VOC’s), and no loud noises as there is no drilling, hammering or seam-welding involved.
  1. Surface Protection
    Excellent protection to the surface of your roof is necessary for weatherproofing and reinforcement. The surface of your roof takes the brunt of all the harsh weather conditions. The sun’s UV rays/heat is the leading cause of roof degradation. It is vital to have a highly reflective roof surface to reflect the UV rays away from the building, protecting the surface of the roof from premature degradation and failures (aka leaks).  The high reflectivity protects the surface of the roof allowing the roof to remain flexible and durable to withstand the different temperature fluctuations throughout the day and different seasons.  The AcryPly and ARM commercial roofing systems provide high reflectively to your roof. You can learn how reflective a roof coating truly is by viewing test results and ratings on the Cool Roof Rating Council’s (CRRC) website. The CRRC provides accurate and unbiased initial and 3-year ratings for solar reflectance, thermal emittance, and solar reflectance index. Take a look at the AcryShield reflectivity ratings used in the AcryPly and ARM system. Reflectivity not only protects your roof surface, it lengthens the roofs’ lifespan, and it increases energy efficiency by allowing the air temperature inside the building to remain cooler. The greater ability the coating has to reflect the sun’s heat away from the building, the less heat the building is able to absorbing. This allows your building to remain cooler for longer with less air conditioning usage.

    Another important factor to surface protection is foot-traffic protection. A durable roof coating such as the AcryShield A550 is ideal for areas that experience high traffic, such as roof hatches, HVAC equipment, drains and other equipment on top of the roof. Walkway pads are also recommended for even more protection against foot traffic and physical abuse.

AcryShield A550 Durable Roof Coating - Offers Superior Roof Protection

Posted by Nicole Gale on Thu, Aug 14, 2014 @ 08:30 AM

 AcryShield A550 a Durable Roof Coating that Provides Superior Protection Against
Foot Traffic and 
Physical Abuse

A550 offers added protection for those area's where extra foot traffic and other
wear-and-tear is likely to occur - specifically near the roof hatch, HVAC systems and other equipment on the roof top

AcryShield A550 is an acrylic elastomeric top coat that can be applied as a multi-purpose base and top coat. This coating has double the toughness of any other AcryShield coating. A550 offers urethane-like qualities with two to three times the level of elongation and tensile strength of our standard roof coatings.

A550 provides superior protection against foot traffic and physical abuse. A550 can be applied over a variety of substrates as a top coating including BUR, Mod Bit, Asphalt, Hypalon, EPDM, TPO, PVC, Spray Polyurethane Foam (SPF), Metal and Concrete. A550 can also be applied as a base coat over SPF and Metal substrates.

A550 exceeds ASTM D6083 requirements for critical properties such as tensile strength, elongation, wet adhesion and weatherability
