As a building owner of a commercial flat roof or metal roof system, one of the many concerns hanging over your head (literally) is the threat of a leak or roof damage. Roof coatings can give you the peace of mind in knowing that your roof system will be protected for years to come. Coatings often avoid the costly hassle of roof replacement by providing additional protection and a decrease in energy costs. The array of available coating options have tripled over the past 25 years. With the advancement in products, the choices have become more complicated. Here is a closer look at the four most popular coating options.
Acrylic Roof Coatings:
Acrylic coatings is a water-based material that is made of a single component that does not require any additional component mixing. Pros of water-based acrylic coatings include low flammability and potential for toxicity hazards. Unlike most other coating options, acrylic materials come in a variety of colors to match your building’s color scheme. Cons include the requirement of many applied coating layers in the right external temperature for proper curing. There are limitations to when an acrylic coating should be applied – too cold and it will freeze; too hot and it will not set properly. When ponding water is present on roof surfaces for a period of 48 hours or more, acrylic roof coatings can begin to re-emulsify to their liquid state and lose adhesion.
By choosing a trained contractor, he will take these issues out of the equation for you!
Acrylic roof coatings is a monolithic, fully adhered, liquid applied roof coating. It has some elastic properties that allow it to remain flexible with temperature changes. Typical roof coatings range from 3mils to 40 mils thick depending on specifications. The roof coating actually becomes the top layer of protection for the underlying membrane, receiving the impact of infrared and ultraviolet sunlight, rain, hail and physical damage.
Benefits of roof coatings:
Commercial Roof Coatings are seamless when they are installed correctly and can add years of life to your roof. “Cool Roofs,” using white elastomeric roof coatings to reflect heat and light away from the roof, provide huge financial benefits in reducing air conditioning costs and equipment wear. Now, the Federal government has created tax incentives for energy-saving improvements, including cool roof coatings. Many states are now offering incentives to contractors and commercial building owners who use cool roof coatings, so you’ll receive another benefit for choosing one of the most effective roof coatings available today.
