If you’re considering a cool roof to save energy, check out these new roof coating technologies that offer high solar reflectivity and resist dirt and stains

by Brianna Crandall — April 6, 2018 — For facilities managers (FMs) and owners interested in the energy and environmental benefits of cool roofs, roofing solutions provider Everest Systems recently introduced solar-reflective topcoat and primer roof coating technologies. The company also announced a top rating from the Cool Roof Rating Council (CRRC) program.

Kystar flexible PVDF topcoat

The fluoropolymer (polyvinylidene fluoride or PVDF) topcoat technology is an innovative technology being applied onto an array of roofing systems for its ability to repel dirt build-up and staining from environmental factors that can diminish reflectance over time, explains Everest Systems. Based on this new technology, the company designed and developed Kystar, a flexible PVDF topcoat, which it says tops out at 88%, the highest reflectivity available in a roof coating.

Kystar is a high-gloss, single-component, water-based coating that is built to provide unsurpassed weathering and color fastness, and resist dirt pick-up and abrasion. This UV-resistant coating is designed to have higher solids, more flexibility, and greater gloss than its competitors.

The combination of properties presents business owners and facilities managers (FM) the opportunity for higher energy savings over installing traditional roofing materials. Choosing Kystar above traditional methods also allows surface temperature reductions of up to 80 degrees F.

With the ability to be applied directly over primed and unprimed substrates, this high-performance topcoating is suitable for use in situations where long-term durability is desired, and dirt or crack resistance is a necessity.

Everprime All Ply primer

Everest Systems also introduced its Everprime All Ply primer for TPO (thermoplastic olefin) roofs. The high-performance roof coating system offers fast drying speed, the ability to be applied in both cold weather and high humidity, and the ability to be installed on brand-new TPO roofing systems.

EverprimeTPO (thermoplastic olefin) roofs are quickly growing in popularity and demand for both residential and commercial flat roof markets. While TPO membranes do offer an impressive number of performance, installation, and environmental advantages, it is vital for the building owner that the quality of coating is superior in order to receive the full benefits of a TPO roofing system, says Everest Systems.

Everprime All Ply is chosen by many to be that superior solution. Composed as a primer for various new and aged single-ply membranes for TPO, this high-quality, plasticizer-free, single-component, solvent-based primer can be applied by a spray brush or a roller.

The roof coating is designed to provide exceptional adhesion to new and aged TPO and PVC membranes, and to provide excellent surface for subsequent application of acrylic, 100% solids Silicone and fluoropolymer coatings.

Cool Roof Rating Council rankings

Everest Systems says it is seeing its hard work pay off. The Cool Roof Rating Council designs accurate and credible methods for evaluating and labeling the solar reflecting and thermal emittance of roofing products. These strict methods of calculating the performance of roofing technology have rated Everest Systems above its competitors.

Everest System’s commitment to excellence has been vindicated in this three-year review of its systems. The sought-after coating system EverCoat HT was shown to have the same initial reflectivity of 87% as a top competitor, but to also retain this same reflectivity of 83% after three years, superseding the competitor by 6%.

Everest Systems was also shown to be one of the few coating suppliers with a gray coating meeting the Title 24 minimum reflectivity requirements of 70%.

Everest Systems notes that its high-performing roof coating technologies can contribute to Energy Star certification.
