Fibreglass roofing, also known as GRP (Glass Reinforced Polyester), offers a visually appealing and reliable solution for weather-proofing flat or pitched roofs. Renowned for its low maintenance and durability, fibreglass roofing comes with a warranty of over 20 years, making it a cost-effective choice for homeowners. This guide will walk you through the essential materials, tools, and steps involved in installing your own fibreglass roof.

Fibreglass Roofing

Understanding Fibreglass Roofing

Fibreglass roofing is a seamless, continuous waterproof solution that consists of layers of chopped strand matting infused with resin and a catalyst. This process creates a strong, durable barrier that protects your roof from the elements. Whether you’re working on a garage, porch, or garden room, fibreglass roofing is versatile and effective.

Essential Materials

To get started with your fibreglass roofing project, you’ll need the following materials:

  • Roofing Resin
  • Fibreglass Matting (often referred to as Chopped Strand Matting or CSM)
  • Roofing Topcoat
  • Catalyst or Hardener
  • Roofing Edge Trims
  • Fibreglass Bandage

For convenience, Roofing Kits Direct offers pre-measured Fibreglass Roofing Kits, tailored to suit various project sizes.

Tools Required for Installation

While many tools required for installation are standard household items—such as buckets, rollers, brushes, and a trimming knife—you will need a few specialist tools as well:

  • Paddle Rollers: These are essential for integrating resin and chopped strand matting without bubbles.
  • Catalyst Dispenser: This tool ensures you add the correct amount of catalyst to your resin and topcoat.

Preparing the Roof

Before applying the fibreglass, it’s crucial to prepare your roof:

  1. Check the Substrate: Ensure your existing roof is sound. If necessary, replace any damaged boards with new ones to create an ideal base.
  2. Install Edge Trims: Lay your roofing edge trims and blend them with fibreglass bandage. This step is beneficial for the main fibreglass wet-out application.

Installing the Fibreglass Roof

  1. Wetting Out: Apply the resin to the roof, ensuring even coverage. Lay down the chopped strand matting over the resin and then wet it out thoroughly. The resin should remain wet when you apply the matting.
  2. Layering: For areas with minimal foot traffic (like a garden shed), a single layer of 450gsm matting is typically sufficient. For light foot traffic, opt for 600gsm, and for heavier use (like balconies), two layers of 450gsm are recommended.
  3. Curing: Allow the fibreglass to cure, which will harden and form a clear, solid surface.
  4. Applying the Topcoat: Finish the installation by applying the roofing topcoat. Available in a range of colours, the most popular choices are dark and light grey, which provide a professional look. The topcoat also has a catalyst mixed in, adding strength and durability.

Maintenance and Cleaning

Unlike traditional roofing, fibreglass roofing is highly resistant to lichen, moss, and ivy growth. If cleaning is needed, a simple solution of soapy water and a brush will suffice.

Benefits of Fibreglass Roofing

Installing a fibreglass GRP roof offers numerous advantages:

  • Safe Installation: No heat is required, and only basic tools are needed.
  • Durability and Strength: Expect a lifespan of over 20 years.
  • Flexibility: Fibreglass can be moulded easily, with a wide range of trims available.
  • Waterproof: The seamless design eliminates potential leak points.
  • Weather Resistance: The waterproof topcoat finish ensures long-lasting protection.
  • Easy Repairs: Fibreglass roofing is straightforward to maintain and repair.

Safety Considerations

Don’t forget to prioritise safety during your installation. Equip yourself with the following protective gear:

  • Gloves
  • Masks
  • Disposable coveralls
  • Goggles or safety glasses
