With all the options on the market for flat roof materials, why should I choose a roof coating system for my building?
Excellent question! Roof coating systems have 4 primary benefits that other flat roof materials cannot offer:
1. Spray Applied – Custom Tailored to YOUR Roof’s EXACT Needs
A roof coating system is applied by spraying the coating directly over the existing aged or failing membrane. This allows the coating to spread to those hard to reach areas, go around and under pipes, fully covering the surrounding surface areas of skylights, gutters, HVAC systems and other equipment placed on your roof. Other flat roof materials, such as single-plies, require you to cut around and patch these areas with a roof sealer. Not only does this add additional cost in labor, but these cut out and patched areas do not provide the same waterproofing protection as a single, fully adhered, monolithic membrane. A roof coating system covers the full surface of a roof field, leaving no unprotected areas to insure full waterproofing. Roof coatings provide excellent protection and coverage no matter what particular characteristics your roof possesses.
A seamless roof membrane is an ideal membrane because there are no holes, seams or patched areas that could create a possibility of leakage to occur. AcryShield roof coatings are packed full of ingredients that allow them to expand and contract with the changes in weather temperature. The seamless membrane moves together and pulls at an even rate across the roof field when temperatures rise and fall. Single-ply membranes such as TPO, EPDM and Hypalon have seams that are welded together and puncture holes where the single-ply is rolled out onto the roof and adhered to the existing membrane. These seams and holes carry the majority of the extra stress and pressure when the weather changes and are often the first areas to being tearing, causing leaks and premature roof failure.
3. High Reflectivity – Added Protection to Prolong Roof Life
Roof coatings come in a range of colors but when looking for a highly reflective coating, you want to choose a bright white one that is full of UV blocking pigments. These pigments are necessary to provide protection for your roof from the leading cause of roof degradation – the sun. The sun’s UV rays break down the surface of a roof, resulting in a brittle roof membrane that easily cracks and tears, causing early roof failure and leaks. This is preventable with a highly reflective roof coating, such as the AcryShield A590. National Coatings has multiple coatings that are listed on the Cool Roof Rating Council for having high reflectivity and solar reflectance. While roof coatings provide excellent reflectivity, it is important to note, proper roof maintenance is key when wanting to extend your roof life indefinitely. The AcryShield Roof Maintenance (ARM) System, provides exceptional waterproofing protection and coverage to your roof. When applied every 10 years, the ARM System allows you to restore your roof to new, while never needing to do a costly tear-off.
4. Non-Disruptive Application
Lastly, a roof coating system is an excellent choice for a company that cannot be disrupted from their normal, daily work environment. When a National Coatings roof coating system is applied to your roof, there are no noises from drilling, nailing or seam welding and due to the ultra low VOC content in the coatings; there are no harmful or strong odors. This is why hospitals, hotels, malls, and many other fortune 500 customers have chosen to use National Coatings products.
