Flat Roofing Supplies

FibreGlassDirect are a well-known online and offline supplier of Fibreglass Flat Roofing Supplies throughout the UK and Ireland. We offer an extensive range of products, competitive pricing and fast delivery.

Over the last 30 years, Fibreglass Flat Roofing Supplies and Materials have become a cost-effective way to repair, build and maintain a roofing structure. With fibreglass roofing supplies readily available online, this article will guide you through the different options on offer.

Fibreglass Roofing Kits

Our most popular product ranges are the ‘Low Cost’ and ‘Professional’ Fibreglass Roofing Kits.

Low Cost Fibreglass Roofing Kits have been designed for non-domestic dwellings such as outhouses or garden sheds. Each kit is supplied with 1 layer of 450g matting, a standard (non-fire retardant) topcoat in light or dark grey, tools and a general-purpose, Lloyds Approved resin.

The Professional range of Fibreglass Roofing Kits is supplied with the same 450g matting, but offer a Flexible Roofing Resin and a fire retardant dark grey topcoat. This topcoat has been certified for its extra fire resistance whilst the resin will aid roof contractions and expansions. Most kits are available with or without tools.

For extra advice on using your fibreglass roofing kit check out our roofing kit guidelines which will provide a step by step guide on how to lay the perfect fibreglass roof.

Fibreglass Roofing Trims

No fibreglass roof would be complete without its trims. Roofing trims are an essential part of the roofing process as they aid drainage and an aesthetically pleasing finish.

Each roofing trim is selected depending on the purpose, shape and size of the roof. Most roofing trims on offer at FibreGlassDirect are available in 1.5 metre or 3 metre lengths. Corner trims are also available to provide reinforcements on corners and returns.

For additional information on which roofing trims you should select, please visit our Roofing Trim FAQ's.

Laminating Products

Resin and Chopped Strand matting form the backbone to the structure of the fibreglass roof. When the resin is applied to the matting it creates a rigid, inpenetrable barrier.

For standard fibreglass roofing projects, 450g matting is sufficient. Where heavier roofing footfall is expected 1 layer of 600g matting is used or 1 layer of 900g in the cases of balconies or walkways.

For fibreglass roofing projects we recommend a choice of 2 resins. The first, Lloyds Approved Resin, is a general-purpose, universal resin used in many hand lay-up projects including water storage tanks and boat building. This resin is approved under testing from the Lloyds Register.

The second resin, Flexible Roofing Resin, will aid the roof during its natural settling. It will also aid thermal contractions and expansions caused by the unpredictable nature of British and Irish weather.


As previously outlined, FibreGlassDirect offer a standard or fire-retardant roofing topcoat. Both topcoats will provide a waterproof barrier to your cured lamination.

Tools & Ancillaries

For every stage of the flat roofing process, ensure you have a good supply of tools and ancilaries such as rollers, roller handles, roller refills, buckets and brushes.

Acetone may be used as a cleaning agent to ensure the tools can be reused.
