The Benefits of our Fibreglass Roof System for Installers

Topseal GRP flat roofing delivers a number of significant benefits which is why it’s usually the first choice when creating new build flat roofs. Many of our installers are so impressed with the product that they use nothing else when undertaking flat roofing projects for businesses and homes.

  • GRP roofing is much safer to install and doesn’t require any difficult to handle machinery and usually doesn’t need heating equipment. That means there’s much less chance of an accident and a general improvement in health and safety rates.
  • When you complete training for Topseal systems, you get all you need to start offering your services to local domestic and commercial property owners.
  • Fibreglass roof materials are extremely durable and you should expect any installation to last for 20 years or more.

The good news is that our products come with a workmanship guarantee up to 40 years.
  • Fibreglass roof systems are flexible and you can choose from a range of different trims to suit the build you are working on. The fibreglass roof can quickly and easily be cut to fit any roof shape or size and the whole system can be installed quickly and efficiently compared to other approaches.

Of course, what most customers want to know is how waterproof and resistant to the weather their new fibreglass roof is going to be. Our GRP fibreglass flat roof systems are state of the art and give full waterproofing with a great deal of durability compared to other products on the market.

How is a GRP Fibreglass Roof Installed?

Fibreglass roofing is the most economical and efficient way to put down a waterproof and durable layer that will last for a long time, whether it’s for a home or a commercial property. A flat roofing system like ours compromises a number of different layers that all add up to make it extremely weatherproof. It’s extremely flexible and can be tailored to fit any space.

The Topseal Fibreglass Roof system comprises:

  • OSB3 decking
  • Topseal resin
  • Fibreglass matting.
  • Topseal durable topcoat.
  • Topseal fibreglass pre-formed trims.

As with any good building work, you need a great foundation and that’s where the installer starts. They begin with laying the board decking down to form a strong base. This can either be insulated or uninsulated and will depend on the building regulations. In most cases, particularly for domestic properties, it’s going to be insulated.

The roof is strengthened further with the preformed trims that are fitted to the perimeter of the roof. The fibreglass matting and the resin are then layered over the decking and finally, a topcoat is applied to completely waterproof the area.

The length of time that this takes will depend on the size of the roof.

What Makes Topseal Different?

GRP or glass-reinforced polyester was actually invented way back in the 1930’s and was used to waterproof boats and ships. The material has been developed over the years and today’s product is not only completely waterproof, it’s light, flexible and easy to work with. All our products come with BBA certification.

Topseal have been producing high-quality flat roofing systems since the early 1990s and we’ve developed a strong reputation during that time for quality and innovation. We’re so certain about the superior quality of our GRP fibreglass flat roofing system that we provide up to a 40-year workmanship guarantee. In fact, we expect that new roof to last at least 100 years.

We also make sure that our certificated installers all receive the appropriate training, whatever their level of experience. Unlike other flat roof system manufacturers, we giver our installers a verification number which customers can check to make sure they are on our register.
