Fibreglass roofs are becoming increasingly popular in the UK due to their durability and long lifespan.

They are made up of layers of fibreglass matting and resin, which are applied to a surface to create a waterproof layer.

When it comes to top coats on a fibreglass roof, the number of coats required can vary depending on the situation.

Below we will explore how many top coats on a fibreglass roof are necessary and the factors that can affect this.

Why Do You Need a Top Coat?

A top coat is the final layer applied to a fibreglass roof, and it is responsible for protecting the roof from UV rays, weathering, and general wear and tear.

The top coat is also responsible for giving the roof a smooth and aesthetically pleasing finish. It is essential to apply a top coat to a fibreglass roof to ensure it lasts as long as possible.

Factors that Affect the Number of Top Coats

Several factors can impact the number of top coats needed on a fibreglass roof, including:

  1. Weather Conditions

The weather conditions in your area can impact the number of top coats needed on a fibreglass roof.

If you live in an area that experiences harsh weather conditions, such as strong winds or heavy rainfall, you may need to apply more top coats to protect the roof.

  1. Type of Resin

The type of resin used can also impact the number of top coats required. Some resins are more durable than others and may require fewer top coats to provide adequate protection.

  1. Purpose of the Roof

The purpose of the roof can also impact the number of top coats needed. For example, if the roof is a commercial building, it may need more top coats to withstand heavy foot traffic or machinery.

Generally, two or three top coats are sufficient for a fibreglass roof. The first coat is known as the gel coat, and it is applied to the entire surface of the roof.

The second coat is the topcoat, which is applied to the gel coat to provide extra protection. If additional top coats are needed, they are typically added at this stage.

It is essential to follow the manufacturer’s instructions when applying top coats to a fibreglass roof. Applying too many or too few top coats can impact the performance of the roof and reduce its lifespan.
