What is Fibreglass GRP?
Known also as glass fiber or GRP (glass reinforced polyester), fibreglass is made up of glass fibres and polyester resin. This material is an excellent waterproofing material and is frequently used on flat roofs. According to BS 6229 and BS 8217, fibreglass roofs are typically classified as flat roofs (defined as having a minimum fall of 1:40 to guarantee a finished fall of 1:80). The term 'fibreglass roof' refers to a flat roof applied with a fibreglass system as a waterproof barrier, typically over OSB3 timber. It consists of a composite laminate painted with a resin topcoat (also called a flow coat or gel coat).
The main advantage of fibreglass GRP flat roofs is that they can be applied directly to existing roofs. A significant benefit of this a

There are many varied flat roof systems available on the market. In this article we compare some of these and identify materials and processes which are involved with each application.
Examined and compared are the following flat roof systems: Concrete, Asphalt, Felt, EDPM and Fibreglass/ GRP.
One of the main advantages with concrete roofing is that it is incredibly strong. Unlike some of its counterparts, it can withstand highly extreme weather conditions. Issues such as wind uplift do not impact concrete flat roofs, and they also have extremely long lifespans.
The obvious downside is the extreme weight of the product. The structure must be able to support the strain of a concrete roof. Concrete roofs also require a sealant to repel water. This sealant is often made from Asphalt felt.
Asphalt flat roofing is inexpensive and easy to apply. In some cases, it is possible to replace an older Asphalt roof by simply overlaying with a new membrane. This can further cut down on costs and installation time. An asphalt roof lasts around 20 years in optimum conditions.
While this is a low maintenance and cheap option, it does have many drawbacks. Impact of light objects, such as tree branches and even hailstone, can damage and tear shingles. This results in leaks and water infiltration.
The use of a hot torch is necessary to apply a felt roof. This process usually involves the laying of three layers. A vapour control base layer is applied first. This is followed by a layer of reinforced felt. A felt cap layer is applied to finish the job. The material has excellent breathable qualities due to its vapour layer, and this prevents condensation.
Felt roofing requires skill and an awareness of health and safety. This is not a method to be
GRP or Fibreglass roofing is one of the best, reliable ways to weatherproof flat, pitched or barrel-vaulted roofs.
Its low-maintenance and quality materials make it one of the most cost-effective roofing methods available.
Materials required to fibreglass a flat roof include;
Fibreglass roofing consists of wetting out layers of glass mat on the roof of the building. When cured, your roof should have strength and provide a continuous waterproof barrier across the surface of the roof. One layer of 450g glass mat is standard for a roof with no footfall, 600g glass mat should be used in areas of light footfall and 900g or two layers of 450g for balconies or areas of heavy footfall.
When the resin has cured, the Roofing Topcoat can be applied. This not only adds colour to the roof but also acts as a tack-free sealant to secure the fibreglass underneath. If there is a requirement for the roof to be walked on after the build, we recommend that a non-slip topcoat is used. To achieve fire resistance topcoat should be applied at a
GRP Roofing Trims are an essential part of the GRP / Fibreglass flat roofing process. Not only do the trims add a professional finish, but they are essential for aiding drainage. With so many roofing trim options to choose from, we are often contacted by customers with lots of questions on how to choose the right types. This article will help ensure you select the right ones!
Each roofing trim has a different purpose, shape and fit. A combination of several trims may be required depending on the size and shape of your fibreglass roof.
Drip Roofing Trims are one of the most popular types of GRP Roofing Trims on the market. They are used at the lowest point of the roof and fitted to the edge of the roof which allows drainage into the gutter.
Fibreglass, a material widely used throughout the UK and Ireland as a convenient way to build flat roof garage extensions.
