Roof coatings are designed for protecting and extending the useful service life of roof assemblies for new construction and more commonly, existing roof coverings, such as BUR, metal, modified bitumen, single ply membranes, and spray polyurethane foam.
Roof coatings are thicker than paint and have higher solids content. Roof coatings are formulated to protect roofs from the damaging effects of weather and the environment, such as UV light, and excessive water and wind. They are formulated to provide protection for many years and are also extremely elastic; they typically contain a high level of top-quality resin. The high quality resins and the volume of resins introduced during manufacturing allow the coating to maintain its elastic properties throughout its life cycle. Once cured, these resins form an elastomeric and durable film, which provides an additional measure of waterproofing and allows the roof coating to bridge small cracks and membrane seams found on roofs. Unlike paint, which is typically applied in portions of a gallon per 100 square feet, roof coatings are applied in terms of multiple gallons per 100 square feet. At PIDNA, we offer a variety of roof coatings which can benefit any type of roof.
Roof coatings are applied to low slope roofs on residential, commercial, and industrial buildings to extend the life of a roof by preventing water, chemical, or physical damage which saves money for the building owner. Certain roof coatings even provide an extra level of waterproofing protection to help shed water to keep building interiors dry. Also, roof coatings are the most effective and least costly option to help buildings save energy.
Every building owner will eventually be faced with the decision to completely tear-off an existing roof or to repair it. In fact, 2.5 billion square feet of roofs are either replaced or re‐coated each year. Given that roofing materials are the third greatest contributor to waste in landfills, roof coatings are an ideal solution to extend the life of a roof and prevent tear-off and waste.
