A roof coating is a massive, fully adhered, fluid applied roofing membrane. It has elastic properties that allows it to stretch and return to their original shape without damage. 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. Today, there are various types of roof coatings on the market that can benefit any type of roof.
The most common types of roof coatings are acrylic coatings, asphalt coatings, polyurethane coatings, and silicone coatings. 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.
Reflective roof coatings reflect visible light and infrared and ultraviolet radiation. This leads to lower roof temperatures which in turn helps reduce cooling costs for buildings with air conditioning units and reduce interior temperatures in buildings with no cooling units. By minimizing cooling costs in warmer climates, peak energy usage is reduced thereby decreasing the risk of power outages and the strain on the electrical grid.
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.
Reflective Coating: This type of roof coating is mainly used to offer protection against sun rays. People who live in areas where there is high humidity and high temperature can consider this type of coating.
Water proofing coating: This type of roof coating is mainly intended to fix any kind of water leak found on the roof of the house. The water resistant layer helps to correct the leak and leave the roof top simply perfect. They are quite expensive. But it is worth investing in it.
Asphalt coating: This kind of coating is mainly used to discard water as well as to ward off harmful effects of the extreme weather conditions. This is also an expensive method of protecting your roof.
Metal coating: It is considered as the most effective type of roof coating since it is mainly used to protect the life of roof. Usually metal when exposed to high temperature it expands. This property helps to cover a wide range of roof area. Compared to other types, metal coating is very expensive.
White covering: This type of coating is widely preferred because of its reflective nature and its effectiveness in reducing the house temperature. You can consider this type of coating so as to cut down cooling cost which you may have to consider other wise.
