Important Roof Coating Terms
Contractors and homeowners apply roof coatings to commercial and residential buildings to extend the life of their roofs. If you are thinking about hiring a contractor to apply a roof coating or applying one yourself, there are a few terms you should be familiar with.
Roof Coating – A liquid applied covering made for the roof of a building to extend the life of the roof. A roof coating can prevent leaks, protect against weathering, and control temperature. Roof coatings are specifically designed for roofs made of many building materials, like steel, asphalt shingles, slate, and tile.
Reflective Coating – A type of roof coating that reflects solar rays, sometimes called a white roof coating. Reflective roof coatings lower the temperature of a home, reducing cooling costs. Metal roofs with white reflective coatings, like those made from steel and aluminum, can drastically reduce indoor air temperatures.
Elastomeric Roof Coating – A stretchable, rubber like roof coating that expands and contracts with changes in temperature, forming a single layer over a roof.
Waterproof Roof Coating – A coating that forms a seal over a roof preventing leaks and pooling water. Waterproof roof coatings can improve the life span of older roofs, and prevent rotting and molding of wood underneath shingles on a residential roof.
Asphalt Roof Coating – A coating applied to older roofs to extend their lives as a form of preventative maintenance. Asphalt coatings are often made from a mixture of asphalt and metal.
Flat Roof – A common type of commercial roof that is almost or completely horizontal, allowing for rain runoff. Flat roofs are often treated with coatings to prevent damage from weathering.
Roof coatings are essentially monolithic roofing membranes that come in liquid form. They are fully adhered and offer an elastic texture in order to stretch and conform to a specific shape, and adjust properly without any damage. They can be applied with a roller, brush or air sprayer. It is common for these waterproof sealants to be applied to both residential homes and commercial buildings alike. They often feel like rubber to the touch, and are typically reflective to deal with UV rays. Roof coatings can be around the same thickness as paint, but sometimes thicker.
All kinds of roofing materials are used on buildings. These can range from metal, to cement tiles, to standard shingles, to rubber shingles. A number of home improvement company locations offer these materials, and they are typically installed by roofing contractors. In fact, it is often a good idea to inquire about various polymer roof coatings and modified bitumen products, which are dark viscous mixtures used in the roofing process, before using one on a residential home. There is a certain system to roofing and applying roof coatings that must be understood. Typically the coatings used in roof repair and leak protection require professional application in order to be reflective, durable, heat resistant, and waterproof.
