The roof is key to ensuring the energy efficiency, comfort, and protection of your building. If you want to keep your roof in prime condition, coating it may be a smart idea. Coating your roof protects and extends its lifespan by covering it in a durable and weather-resistant material. Roof coating is a simple process, but there are many questions building owners may have about it. Below, find out what this standard roofing feature entails.

Frequently Asked Questions About Roof Coating

How much does roof coating cost?

Roof coating costs vary based on the type of material you use and whether you install it yourself or have a professional do it. For materials alone, the cheapest option is acrylic which costs about $0.15 to $0.75 per square foot. The most expensive material is ethylene propylene diene terpolymer, or EPDM, which costs between $1.50 to $2.50 per square foot. Other materials like polyurethane, bitumen, and silicone have costs that fall between that range. As for installation costs, EPDM has the lowest cost at around $0.25 to $1.00 per square foot. Polyurethane is the most expensive at $1.50 to $3.00 per square foot.

What are the benefits?

When you install a roof coating, you limit the heat transfer from the sun above your facility. With less sunlight getting through and penetrating your building, the space will be cooler, and you may even be able to save on air conditioning costs as a result. The coating can also be thought of as a form of waterproofing to keep out moisture and prevent corrosion.

Should new roofs be coated?

Even if your roof is new, coating it can help reduce heat transfer and lower energy costs. New roofs are actually better suited for roof coating, as they are free of damage. The material can then be applied evenly and work more efficiently. 

Are primers required?

If your roof is in poor condition, a primer may be required to make sure the coating takes effect properly. In most cases, a thorough cleaning is necessary. If major stains and surface damage remains, a primer may be needed.
