Roof coating is a way to extend the life of a roof. There are many different types of coatings available including reflective coatings. The coatings are comprised of acrylics, silicones, urethanes, and other types of materials. Almost any type of roof can be coated including: single-ply, metal, built-up-roof systems, and modified bitumen roofs.
Roof Coating provides 3 main benefits: increase in the life of the roof, reduction in energy usage and aesthetic improvements. Let’s take a look at each.
Increase in the life of the roof
Roof coating works in two ways to extend the life of a roof. The first is by providing a defense against Ultraviolet (UV) rays. Just like your skin, your roof needs this protection because UV rays damage the membranes in the roof causing it to age more rapidly. Secondly, the coating works to help mitigate leaks. Keep in mind extensive leaks cannot be repaired through coating and are not a long-term solution for a leaking roof. Coatings work to help extend the life of a roof up to 10 years or in some cases more. The roof can be coated again the in the future. Coatings help to make a roof more durable. During extreme bouts of weather including: heat, rain, snow, sleet, and hail; the dwelling owner wants to ensure their dwelling is not compromised due to the weather. A good coating will help reduce damaged caused by weather conditions. Take into consideration if during the raining season a puddle sat on the roof for an extended period of time; an effective coating should not be affected.
Reduction of energy usage
Coatings work to help protect against UV Rays by the way of reelection. Without this protection the heat would get trapped inside the dwelling. When the dwelling is hotter typically it takes longer to cool resulting in higher energy usage. Total energy savings will depend on where the dwelling is located. It is highly suggested that when planning to coat a roof that the dwelling owner meet with an energy consultant.
Old rusted roofs can be made to look almost brand new again. Even though the roofs rust problem would have to be solved first, adding a coating to a metal roof would improve its looks greatly. Replacing a roof can be far more costly than applying coating to a roof. Coatings come in an array of colors from reflective white to earth tones that can complement the surroundings. There is also the option for brighter tones to let the dwelling standout. A good coating also has the ability to resist dirt. Of course no coating will resist all debris however, to keep its energy efficiency a good roof will have a great deal of dirt pickup resistance.
A few things to consider when choosing a roof coating include durability, temperature flexibility, the resistance to pick up dirt, adhesion, and resistance to water. With good research a home owner should be able to find a coating that works well for the type of roof they have.
