Roof Coatings FAQs

What is roof coating?

Roof coating is a protective layer applied to the surface of a roof to enhance its durability, weather resistance, and energy efficiency. It helps to prevent leaks, reduce heat absorption, and extend the lifespan of the roof.

What kind of roof can be coated?

Almost all types of roofs can be coated. Roof coatings are versatile and can be applied to various roofing materials, including metal, asphalt, bitumen, EPDM, TPO, and more.

Is roof coating suitable for a flat roof?

Yes, roof coating is often used on flat roofs to provide an additional layer of protection against water, UV rays, and other environmental elements.

Why should I consider roof coating for my building?

Roof coating provides several benefits, including waterproofing, UV protection, and energy savings. It can extend the life of your roof, reduce maintenance costs, and improve the overall energy efficiency of your building.

Does roof coating require professional installation?

It is often recommended to hire professionals for larger or more complex roofing systems to ensure proper application and performance.

Are roof coatings expensive?

No. Roof coating is a fraction of the cost when compared to roof replacement.

How is coating applied?

The coating can be applied using spray, brush or a roller. Before you can apply roof coating, you’ll need to put on a coat of primer. Primers are used on concrete and masonry, as well as gypsum and block. Brick and metal surfaces also need to be coated. Before you can apply the primer, the roof needs to be completely dry and clean. An expert might need to look at the roof substrate to decide which type of primer is best for your project.

Can roof coating be applied during any season?

The ideal time for roof coating application depends on the specific product and local climate conditions. Some coatings may have temperature and weather restrictions, so it’s essential to follow the manufacturer’s recommendations.

What is the drying and curing time for roof coating?

Drying and curing times vary depending on the type of coating and environmental conditions. It’s essential to follow the manufacturer’s guidelines for application and allow adequate time for the coating to dry and cure.

How long will the coating last?

Typically roof coating can extend the life of a roof by 10 to 15 years. This may depend on the thickness of coating and weather conditions.

Can a rusted roof be coated?

The rust conditions have to addressed before you can coat a metal roof. Rust can be removed or treated with a corrosion inhibiting primer. If the roof is zinc or aluminum, it can be cleaned and then coated.

Will the roof coating stop roof leaks?

In what weather conditions can the coating be applied?

Air temperatures: The best temperatures in which to apply a surface coating are between 56°F and 99°F. Lower air temperatures result in delayed curing times, which affect the coating’s performance.

Surface Temperature for Roof Coatings

Surface temperatures: During the day, it is common for surfaces to absorb heat and be warmer than the air temperature.

What maintenance is done for roof coatings to last?

A roofing contractor will begin by visually inspecting to look for signs of damage and inspect the gutters and drains.

Does roof coating come in different colors?

Yes, roof coatings are available in various colors. Choosing a reflective or light-colored coating can enhance energy efficiency by reflecting more sunlight and reducing heat absorption.

How does roof coating contribute to energy efficiency?

Roof coatings with reflective properties can help reduce the heat absorbed by the roof, leading to lower indoor temperatures. This can result in energy savings by reducing the need for air conditioning.

What is the difference between a roof coating and sealant?

Sealant seals up the edges of your roof, around air vents, vents, and screw heads. Roof coating covers the whole roof and is used to fill in any cracks and create a smooth, waterproof surface to stop leaks.
