When to ask for an assessment
Whether GRP is right for your roof
The condition beneath the visible finish is essential. Movement, moisture or unsuitable preparation can affect any new system.
- Existing flat roof has repeated local leaks
- Perimeter trims or upstands are failing
- The roof deck feels uneven or moves under load
- A garage or extension roof needs renewal
- Outlets and drainage details need improvement
- The current finish is cracked or deteriorated
Scope of work
A sound base first, then the waterproofing
A suitable GRP roof depends on preparation, reinforcement and careful detailing around every edge.
Laminated surface
Apply the specified reinforcement and resin as a continuous waterproof layer.
Trims and topcoat
Complete compatible perimeter details, upstands, outlets and the protective finish.
Planning measurements
Work out your roof area first
The planner gives you a rough surface area plus tile, membrane and batten quantities. It is a starting point for the conversation, not an order list, so nobody should be buying materials off it.
Roof area and materials planner
Put in the building dimensions, the pitch and the product coverage. It takes a minute and makes the first phone call a lot more productive.

Seamless does not mean detail-free
Corners, wall junctions, edge trims and outlets require deliberate workmanship. These small areas often decide how well the wider flat roof performs.
- Find where the water is getting in, not just where it shows
- Agree the scope in writing before anyone starts
