Winter is right around the corner, and many Atlanta residents are looking for ways to winterize their homes to help manage their heating bills. With the cooler temperatures rolling in, now is the time to make sure your roof is properly maintained and protected. A specially formulated roof coating might be the answer to your roofing needs.

What are these coatings used for?

Coatings are compounds formulated to protect, waterproof and/or increase the lifespan of a roof. They are used to shield roofs from wind, sun, rain, hail and snow. In addition, they are often used to treat minor repairs and help with shingle wear to extend the lifetime of an existing roof and delay the need for a complete replacement.

Why should I coat my roof?

Are you interested in prolonging the life of your roof? Do you want to minimize your long-term maintenance costs, or perhaps you want to avoid a very costly roof replacement? If you said yes to any of these questions, then a roof coating is probably a good option for you.

Roof coatings are used for four different purposes. Some roof coatings provide one point of protection, whereas others can protect your roof in several different ways. The various benefits of roof coatings are described below:

  • Existing Roof Protection and Longevity: Roof coatings create a layer over your existing roofing to protect it from the elements. These coatings can help reduce the cost of maintenance while prolonging the life of a roof. Usually, these coatings are designed to help strengthen and thicken the existing roof surface. This is a good option to consider if you are looking to increase the lifespan of worn roofing, especially if you have a limited budget.
  • Solar Protection: Certain types of coatings can be used to protect roofing from the effects of the sun. These kinds of coatings always have some kind of reflective element to keep the rays of the sun from penetrating the roof. The formulas are either pigmented, a reflective white or a bright silver colored aluminum. By reflecting the radiant heat, they also lower roof and attic temperatures, reducing utility bills. That's why these coatings are sometimes called "cool reflective coatings."
  • Energy Efficiency: Some coatings are formulated to help maintain roof and attic temperatures to help lower utility bills. These coatings have an insulation factor that keep heat and cold air from seeping into your house.
  • Waterproofing: This type of coating helps protect the roof from moisture damage and heavy rains. It is also helpful in situations where the existing roof has leaks.

Types of Roof Coatings

There are several kinds of coatings, each formulated for a different type of protection for your roof. The coatings typically contain an elastomeric resin that makes them flexible so that they can expand and contract with the changing seasons and temperature conditions. This elastic quality prevents the peeling and cracking of the coating, keeping it intact. Some of the more common kinds are described below:

  • Asphalt: These coatings usually contain some aluminum for its reflective properties or fiberglass for strength to help protect roofing.
  • Acrylic: These coatings are white and very reflective, making them a great choice for solar protection.
  • Urethane: This material is used for waterproofing roofs. Your roofer will use a different formulation, depending on what your roof is made of.
  • Ceramic: These coatings provide both heat resistance and UV protection with the incorporation of ceramic microspheres.
  • SPF: This kind of roof coating is used for insulation, is weather-resistant and helps with energy efficiency. This is spray foam that is then covered with a waterproofing compound to prevent deteoriation of the SPF coating.


You can find roof coating supplies at any home improvement store. However, for most people, this is not a typical do-it-yourself project. A roofing specialist would know best which product to use on your particular roof based on your needs and the material your roof is made from. In addition, the coating has to be applied properly, with a consistent thickness, in order to function at its best. Formulations must be mixed properly, and they must be applied in the right temperature conditions on dry roof surfaces. Any areas that do leak should be patched before application.

There are many factors to consider to ensure a proper application; factors that a professional is more familiar with and can better address. Are you interested in learning more about protecting your roof? Contact a roofing professional today and get your roof protected before winter arrives.
