🏠 Getting Started with Your GRP Roofing Project

Thinking about installing a GRP (fibreglass) roof? Great choice — it’s durable, long-lasting, and perfect for flat roofs. Whether you’re tackling a shed, extension, or full roof renovation, getting started is easier than you think.

Here’s what you need to know before diving in:

🧰 The 3 Essentials You’ll Need

To complete a GRP roofing project, you’ll need three key components:

1. A GRP Roofing Kit (Click)

This is your core material — it includes the resin, topcoat, and fibreglass matting. Kits are available in different weights:

• 300g Kit: Ideal for small, light-duty jobs
  💷 From ~£20.45/m²

• 450g Kit: A balanced choice for most domestic roofs
  💷 Best value at ~£14.13/m²

• 600g Kit: Built for strength — great for walkable surfaces
  💷 From ~£17.81/m²

Each kit is sized by area (e.g. 10m², 20m², etc.), so pick one that matches your project.

2. Trims (Click)

GRP trims are used to form the edges and corners of your roof. These ensure proper drainage and a neat, professional finish. Common trims include:

• Drip trims (for water runoff)

• Upstands (for wall abutments)

• Internal/external corners

💡 You’ll typically need around 1 linear metre of trim for every 1 m² of roofing.

3. Tools (Click)

The right tools make the job smoother — and safer. Here’s what you’ll need:

• Rollers for resin and topcoat application

• Brushes for detailing

• Buckets and mixing sticks

• Protective gear (gloves, masks, goggles)

• Acetone for cleaning tools

Many suppliers offer tool kits specifically designed for GRP installation.

💡 Pro Tips Before You Start

• Plan your layout: Calculate your surface area and order slightly more materials to account for wastage.

• Check the weather: GRP is best applied in dry, mild conditions.

• Practice safety: Always work in a ventilated space and wear PPE.
