Your roof is one of the most important components of your home. Caring for your roof with regular maintenance, repair, and upkeep is an essential part of protecting the investment that is your home. Even with the best care plan, however, your roof will still wear out over time. Are there things you can do to add to its strength and longevity? Consider a roof coating to add strength and performance to this important part of your home.

What Are Roof Coatings?

A roof coating is a liquid or semi-liquid substance that is applied to your roof’s surface to protect it from the elements and extend its life span. Roof coatings are made from a wide variety of materials, such as silicone, acrylic, polyurethane, and asphalt.

Coatings are usually applied to flat or low-sloping roofs, though they can be used on all types of roofs. They are used as an alternative to traditional roofing materials like shingles and tiles, and they can be used to restore an existing roof and provide a protective coating for a new roof as well.

Benefits of Roof Coatings

Several benefits come with adding an extra layer of protection for your roof, thus reducing the amount and frequency of maintenance you might need to perform on your home.

Water Protection

The primary function of a roof coating is to protect your roof surface from water damage. The coating, once applied, creates a waterproof barrier that prevents water from penetrating the roof material and causing damage to the underlying structures.

UV Protection

Some roof coatings contain reflective materials that help reduce the amount of UV radiation that is absorbed by the roof. UV rays can cause damage to roof materials over time, such as cracking and fading. Properly applied coatings reduce the amount of heat that is absorbed and transferred into your home, reducing the need for air conditioning during hot weather.

Seals Leaks

Roof coatings can also help seal existing leaks and prevent new ones from forming. They can be used to repair small cracks and holes in the roof surface, preventing water from entering the home through these openings.


Some roof coatings are made from eco-friendly materials, which can be better for the environment than traditional roofing materials. Because they can help to reduce energy costs, they can also be considered an environmentally friendly choice.

Extended Life Span

Most importantly, a roof coating can help to extend the life of a roof by protecting it from the elements. It can help to prevent the growth of mold and mildew, which can weaken the roof structure over time. This can reduce the need for costly repairs or replacement of the roof.

How Is Coating Applied to Your Roof?

Roof coatings can be applied to a roof in several different ways, depending on the type of coating being used and the size and shape of your roof. Spray application is a popular method for applying roof coatings. Technicians use a spray gun to apply the coating evenly over the roof surface. This method is typically used for large, flat roofs.

Roll-on application involves using a paint roller to apply the coating to roof surfaces. This method is often used for smaller roofs or for areas where a spray gun cannot be used. Brush application is similar to a roll-on application, but it involves using a brush to apply the coating to the roof surface. This method is often used for areas where a roller cannot be used, such as around vents or other protrusions.

Trowel application allows for even coating of material over the roof surface. This method is often used for areas that require a thicker coating, such as areas that are prone to pooling water. Some roof coatings come in the form of a self-adhesive membrane that can be applied directly to the roof surface. Adhesive surfaces are particularly effective on flat roofs or roofs with a low slope.

How Much Does Roof Coating Cost?

The actual cost of a roof coating will depend on the size and shape of your roof, as well as the expertise of the contractor applying the coating. Other factors, such as the condition of the roof and the need for repairs, may also affect the total cost of service. It’s always a good idea to get multiple quotes from licensed and experienced contractors to ensure that you are getting a fair price. In general, you can expect to pay the following for various roof coating materials:

  • Acrylic: $0.75-$1.50 per square foot
  • Silicone: $2.00-$5.00 per square foot
  • Polyurethane: $3.00-$6.00 per square foot
