There are an array of different types of roof coating that you can install or apply to your existing roof system. Depending on your needs and requirements, there may be a form of coating that best suits your commercial property. Some coatings are applied before commercial spraying is completed, and others can form a protective layer on the roof and paint to reduce fading, leaks and dirt build-up.

So, what kind of roof coatings are out there and which ones will be beneficial to you? Here we will dive deeper into the different types of roof coatings so that you can form an understanding of the benefits and drawbacks of each.

Types Of Roof Coatings

Commercial properties are built using various different materials, meaning that you may require different forms of protection depending on the materials that have been used throughout your roofing system. Some roof coatings are best suited to metals, such as pipework, while others are best suited as a top coat after spraying of an industrial site. To help you understand more about the benefits of roof coatings, and which ones are best for you, we will be going through the following:

What Is Roof Coating?

Although we see roofs as being the protectors of our building, it may come as a surprise to find out that roofs themselves actually need protecting as well. Roof coatings are the protective layer for your properties roof, helping to reduce damage caused by unwanted guests and adverse weather conditions.

There are many ways in which a roof may become damaged, including rays from the sun fading the colour and coatings on your roof. Roof coatings are also able to provide a waterproof layer, ensuring that you don’t experience any leaks and mould growth. Moisture can formulate on the top of your roof, especially in the UK where we experience a lot of downpours.

Benefits Of Applying Roof Coating

Due to the ability to protect your property and roofing system, there are an abundance of benefits that come alongside roof coatings. Some of these benefits include the following:

  • Reduced use of aircon – coating’s can lower the roof surface temperature, which can, therefore, reduce your properties overall temperature by around 10 degrees.
  • Extends roof life – coatings can help to create a resistance barrier between weather and the roof, meaning that you are able to increase its lifespan.
  • Various materials – roof coatings come with various different materials for you to choose from, meaning that you are able to find a roof coating suited to your desired requirements and style preference.
  • Fade resistant – coatings such as reflective roof coatings are ideal for trying to avoid discolouring of the roof. This is because it is able to reflect the sunlight from the roof.
  • Environmentally friendly – some roof coatings have been made environmentally friendly, so you can ensure that your business follows your values in creating a brighter and cleaner future.

Silicone roof coating has been used for many years on various properties; both domestic households and commercial buildings. It acts as a protective layer against intense UV rays as well as dampness, making it ideal for those with properties that experience extreme rainfall. Although it could be potentially more expensive to install, it is extremely effective and has a long life span, making it a worthwhile investment.

Unlike some other roof coatings, silicone can be applied to your roof system with one thick coat, making it an extremely efficient form of coating for those that can’t afford downtime. Silicone coatings are known to be one of the highest performing roof coatings you can opt for, due to the scientific formulation that allows the coating to form an impermeable membrane that can resist water and sunlight better than any other coating option.

An acrylic coating has been made with acrylic polymer resin, which has been designed to be applied over an existing roof material to restore and renew for ultimate roof protection. Acrylic forms of coating are best for long-lasting and durable solutions as the coating can hold the film together to create a flexible and strong roof.

One of the biggest benefits to having acrylic roof coating is that it can reduce your energy costs through its ability to reflect heat away from the building, allowing the temperature inside to remain low and cool. This is beneficial to those who wanted to coat their office building or a factory building that requires low temperatures to maintain effective and efficient productivity.

Bitumen roof coating comes alongside an array of benefits, with one of the most prominent being the fact that it is incredibly water-resistant. Not only is it resistant to water, but also to low and high temperatures, snow and the freezing/thawing process. The formula used to create bitumen allows it to formulate a tight bond with the material on your roofing system, ensuring that it stops leaks.

Although there are many advantages to having bitumen roof coating, there are also a range of disadvantages that could prove a significant drawback. The main disadvantage is the fact that it is only available in a black colour. Not only does this mean that it may not fit in with the aesthetics of your building, but it will also cause light to be attracted to the roof rather than reflected. Although this may be beneficial to properties located in a colder area, it can dramatically affect the temperature of your commercial property, meaning that you may find yourself spending more on energy bills to cool the building down.


Much like acrylic roof coatings, polyurethane is durable and flexible, able to restore both flat and metal roofing. Polyurethane coating systems are able to prevent leaking, improve property appearances and save you a lot of money. There are two main types of polyurethane coatings: aliphatic and aromatic. To understand this form of coating a little better, let’s dive deeper into the differences between the two:

  • Aliphatic – Holds colour for longer, resistant to dirt build-up and are typically used as a top coat for other roof coatings or as a cladding coating.
  • Aromatic – a lot less expensive than aliphatic coatings, are not as good with UV light and is usually used as a base coating for cladding and roof spraying.

There are several benefits to using polyurethane coatings such as its ability to attach to traditional commercial roof cladding, including metal. It is usually an effective form of roof coating when you use the aliphatic and aromatic at the same time as a base and top coat for your coloured spraying.

Using Elastomeric for your roofing coating will create a seamless finish with a waterproof system and is sprayed over pipes, hatches and other equipment that you may find on your roof. When the coating is sprayed, it begins to melt on the surface, creating no seams and forming a hard protective layer. The coating is likely to last you around ten years, if not more, making it a cost-effective solution for your roofing system. Not only is the coating long-lasting, but it also forms a protective layer that is both durable and environmentally friendly as it often contains either extremely low or zero VOC.

Not only does the material come with an array of benefits due to its performance, but it is also applied with minimal noise and low smell, meaning that you are able to install the roof coating while your employees continue to work on the premises. This means that while it may be slightly costly to install, it does mean that you are able to continue productivity.


Many commercial buildings have aluminium cladding surrounding their building; both the sides and the roofing system. Aluminium is an exceptional roof coating material, as it comes with an abundance of benefits that outweigh the disadvantages. Some of these benefits include:

  • Reflects the sun
  • Keeps the property cool in the summer
  • Insulates the property for the winter
  • Long-lasting roofing solution
