Do Roof Coatings Really Protect Roof Membranes and Extend Roof Life?

Many people seem to think that roof coatings are a waste of time and money. They believe these coatings don’t do anything to protect the roof membrane or extend the roof’s life. Is this true, or are people just skeptical because they don’t understand how roof coatings work?

In this article, we will discuss the benefits of using roof coatings and dispel some myths about them. We will also provide information on how to properly apply roof coatings so that you can get the most out of them.

What Exactly is a Roof Coating?

A roof coating is a seamless, monolithic (single layer), fully adhered, fluid-applied membrane. It is typically spray-applied and can be reinforced with polyester or fiberglass fabrics. Some roof coatings are also available in rolled form, making them easier to transport and apply.

Roof coating system components include a base layer, typically a primer, one or more reinforcing layers, and an outer layer. The base coat layer bonds the system to the roof substrate and can provide some crack-bridging capability.

The reinforcing layers provide physical strength and tear resistance. The outer layer protects the system from ultraviolet (UV) radiation and weathering. All roof surfaces must be coated, including parapets, flashings, curbs, and penetrations.

Benefits of Using a Roof Coating

Some people may view roof coatings as nothing more than an extra layer of protection for their roof. However, there are several benefits to using a roof coating, including:

1. Reduces Thermal Shock Damage

If you live in an area with large temperature swings, a roof coating can protect your roof from the thermal shock that comes with those changes. When the temperature drops suddenly, it can cause the water on your roof to freeze. This can lead to cracks and other damage to your roof. A coating will help insulate your roof and prevent this damage.

2. Reduces Ultraviolet Damage

Roof coatings can help protect your roof membrane from ultraviolet (UV) damage, which can cause the roof to deteriorate and break down over time. UV rays can also cause the roof to become discolored and faded. A good quality roof coating will reflect the UV rays away from the roof, helping to keep it looking new for longer.

3. Reduces Air Pollution and Greenhouse Emissions

It is estimated that roof coatings can reduce air pollution and greenhouse emissions by up to 85%. This is because they reflect heat and UV rays away from the building, which helps to keep the interior cooler. This reduces the energy required to cool the building, releasing fewer emissions into the atmosphere.

4. Protects Against Roof Leaks and Ponding Water

A roof coating can provide additional protection against roof leaks and ponding water. By creating a barrier between the roof surface and the elements, a roof coating can help to prevent leaks from occurring. The roof coating protects the existing roof system from further damage.

5. Lowers Energy Costs by Up to 20%

Lowering energy costs is one of the main benefits of having a roof coating. By reflecting the sun’s rays, your air conditioner won’t have to work as hard to keep your building cool, which can save you up to 20% on your energy bill. Not only does this lead to lower monthly bills, but it also helps reduce your carbon footprint.

6. Reduces the Urban Heat Island Effect

The reflective properties of a cool roof can also help reduce the “urban heat island” effect. This is when cities are significantly warmer than rural areas because of all the dark surfaces that absorb heat. By reflecting more of the sun’s heat, cool roofs can help lower temperatures in cities, improving air quality and reducing the number of heat-related illnesses.

7. Increases the Lifespan of a Roof

Having a roof coating applied to your commercial roof can help increase its lifespan. A good quality roof coating will protect your roof from the elements and extend its life by many years.

Tips On How To Properly Apply A Roof Coating

It is essential to properly apply a roof coating to get the most out of it. Follow these tips to ensure proper application:

What you need:

  • A brush or roller
  • A clean surface
  • Roof coating
  • Step #01 – Clean the surface

    The first step is to clean the surface. This will ensure that the roof coating adheres appropriately. Use a brush or roller to remove any dirt, debris, or dust from the surface. If any areas are particularly dirty, you may need to use a cleaner or degreaser.

    Step #02 – Apply the roof coating

    Once the surface is clean, you can apply the roof coating. Use a brush or roller to apply an even coating layer over the entire surface. Follow the manufacturer’s instructions for coverage and drying time action! Don’t apply in freezing temperatures because the coating won’t adhere properly, and make sure the surface is completely dry before you begin.

    Step #03 – Let it dry

    After you have applied the roof coating, let it dry completely. This usually takes around 24 hours. Once it is dry, the layer will create a barrier that will protect your roof from the elements.

    Applying a roof coating is a simple process, but it is essential to follow these steps to ensure proper application. By following these tips, you can ensure that your roof is properly protected and that the coating lasts for many years.

    Different Types of Roof Coatings

    There are several different types of roof coatings, each with its own unique benefits. Here are a few of the most popular types of roof coatings:

  • Elastomeric roof coating – Elastomeric coatings are one of the most popular roof coatings. They have elastic properties, which allow them to expand and contract as the temperature changes. This makes them ideal for roofs that experience extreme temperature changes, such as those in desert climates.
  • Acrylic roof coatings – An acrylic roof coating is a liquid-applied monolithic (single layer) membrane. It is typically white and reflected sunlight, which can help reduce cooling costs for buildings with large roofs. Acrylic coatings are also very durable and can extend the life of a roof. It is UV stable and resistant to degradation from the sun’s rays.
  • Asphalt roof coating – Asphalt roof coatings are a modified bitumen-based product similar to tar. They are typically black and sticky to the touch. Asphalt coatings have been used on roofs for many years to provide a waterproof barrier.
  • Silicone roof coatings – Silicone coatings are the newest type of roof coating on the market. They are white, Reflective, and extremely durable. Silicone coatings are applied in a very thick layer (usually around 30-60 mils), and they act as a barrier to reflect UV rays, which helps keep the building more relaxed and can reduce energy costs by up to 40%.
  • The roofing industry is constantly changing and evolving, and new products are continually being introduced. It can be challenging to keep up with the latest trends and developments. However, it is important to stay informed to make the best decision for your roof.


    So, do roof coatings really protect roof membranes and extend roof life? The answer is a resounding yes! Roof coatings provide an excellent barrier against the elements, helping keep your roof in top condition for many years to come. If you’re looking for a way to prolong the life of your roof, a roof coating is definitely worth considering.
