Roof coatings play a significant role in extending the lifespan, functionality, and appearance of your roof. They provide an additional layer of protection against extreme weather conditions, ultraviolet rays, and general wear and tear. They also contribute to increasing the energy efficiency of your home or commercial building. This in-depth guide will shine a light on everything you need to know about roof coatings.
The Basics of Roof Coatings
Understanding the basics of roof coatings will give you an insight into their importance. Essentially, roof coatings are products that can be applied on rooftops to protect and extend the roof’s life. They're typically fluid-applied over the roofing membrane, forming a solid, monolithic, watertight layer that fully adheres to the substrate.
Types of Roof Coatings
There are different types of roof coatings, each with unique properties:
- Acrylic Coatings: Ideal for sunny climates, as they reflect sunlight and UV rays. They tend to be water-based and have a low volatile organic compound content.
- Silicone Coatings: Known for their excellent weatherproofing properties. They are durable and can resist weather extremes.
- Polyurethane Coatings: These are robust and can handle high levels of foot traffic. They are also excellent for roofs that tend to pond water.
- Asphalt Coatings: Characterized by excellent water and weather resistance.
The Benefits of Roof Coatings
Extended Roof Life
The primary benefit of roof coatings is that they considerably extend the lifespan of your roof. They create a resistant layer that withstands the elements, slowing down the rate of ageing and deterioration. This way, the need for frequent repairs or a complete roof replacement is eliminated or heavily delayed.
Energy Efficiency
Roof coatings can drastically improve the energy efficiency of a building. The reflective properties of most roof coating materials help to reflect the sun’s rays. This minimises the absorption of heat, thereby reducing the need for excessive air conditioning. In turn, this results in lower energy costs.
Aesthetics
Roof coatings can also enhance the aesthetic appeal of a building. The coatings come in a variety of colours that can complement the exterior design of the house or building. Moreover, it gives roofs a uniform, clean look that can be quite appealing.
Cost-Effective Maintenance
The protective values of roof coatings make it a cost-effective solution for roof maintenance. By preventing damages from occurring in the first place, expensive repairs are avoided. Therefore, the cost of maintaining the roof becomes significantly lower when a roof coating is applied.
Frequently Asked Questions about Roof Coatings
How often should roof coatings be replaced?
The typical lifespan of a roof coating depends on the type of coating, the climate, and the level of exposure to harsh weather, but it generally ranges from 10-20 years. Regularly checking your roof coating for signs of wear and tear such as cracking, peeling, or blistering can help determine when a replacement is necessary.
How are roof coatings applied?
Roof coatings are applied using either a brush, roller, or a spray. The type of application method chosen often depends on the size and complexity of the roof. Spraying can cover larger areas quickly, but brush and roller applications provide more control and precision.
Can you put roof coating over old coating?
In many cases, a new roof coating can be applied over an existing one, as long as the old coating is still in good condition. Any blistered, loose, or damaged old coating must be removed before applying a new one. It's also essential that the new coating is compatible with the old one.
Can roof coatings withstand extreme weather conditions?
Yes, roof coatings are designed to provide protection against all types of weather conditions, from intense heat and sunlight to heavy rainfall and wind. Different types of coatings offer varying levels of resistance against specific weather conditions.

Pros of Roof Coatings
Extended Roof Lifespan
One of the key advantages of applying roof coatings is the extension of the roof’s lifespan. Roof coatings can help protect the roof from harmful elements such as ultraviolet radiation, water damage, hail, and windblown debris, and harsh weather conditions. By adding a protective layer, the roof's lifespan can be significantly prolonged, potentially by up to 25 years, depending on the quality of the coating and the initial state of the roof.
Energy Efficiency
Reflective Properties
Roof coatings, particularly those with reflective capabilities (like white or light-colored coatings), help in reflecting sun rays and reduce heat absorption. This lessens the need for excessive air conditioning during warmer months, as the interior temperature stays cool. This leads to considerable energy savings and reduces the building’s carbon footprint, assisting in efforts towards sustainability and environmental preservation.
Cost-Effective Maintenance
Aside from being a preventative measure, roof coatings can be a cost-effective maintenance solution. Given the ability to renew and repair a roof's surface, applying a coating can save you from expensive reroofing or extensive repair costs. Roof coatings extend the life of the roof, delaying the need for a costly and time-consuming replacement.
Enhanced Aesthetic Appeal
Roof coatings can make a roof look brand new and more visually appealing. They are available in a variety of colors allowing property owners to choose a hue that complements the building’s overall design. This can increase the property's aesthetic appeal and potentially increase its market value.
Environmental Sustainability
The production of roofing materials contributes significantly to waste generation. By extending the lifespan of existing roofs with the application of roof coatings, the demand for new roofing materials can be decreased. This mitigates the environmental impacts associated with roofing material production, transportation, and installation. Some coatings are also low in volatile organic compounds (VOCs), making them an eco-friendly choice.
Cons of Roof Coatings
Initial Cost
Despite the long-term savings, the initial cost of the roof coating application can be high. The price varies massively depending on the type of coating, the size of the roof, labor costs, and other factors.
