What's included

When you compare quotes, check what's actually in them. Ours include the things that determine whether the job lasts:

  • Suitability assessment for GRP
  • Deck preparation — GRP needs a sound, dry deck
  • Laminate and topcoat applied seamlessly
  • Integrated GRP trims and detailing
  • Clean-up and waste removal

How we install it

Step 1

Assess

We check the deck and conditions — GRP needs a sound, dry deck and suitable weather to cure.

Step 2

Prepare

The deck is prepared (often a new ply deck) and trims are set out.

Step 3

Laminate & topcoat

The fibreglass laminate is applied and finished with a coloured topcoat for a seamless, solid surface.

Ideal for

  • Balconies and walk-on roofs
  • Dormers and visible flat areas
  • Roofs wanting a seamless, smart finish

Options & finishes

  • Range of topcoat colours
  • Anti-slip finish for walk-on areas

Important considerations

  • GRP needs a sound, dry deck and suitable temperatures to cure — we plan installs around the weather.
  • It's less forgiving of movement than membranes, so it suits stable, well-built decks; we'll advise if another system is better.
  • Carries a 10-year workmanship guarantee; manufacturer warranty is separate.

GRP Fibreglass — your questions answered

Is fibreglass good for flat roofs?

Yes, on the right roof — it gives a seamless, hard-wearing, walk-on finish. It needs a sound, dry deck and decent weather to install, so we assess suitability before recommending it.

Can I walk on a GRP roof?

GRP is walkable and a popular choice for balconies, with an anti-slip option available. We'll specify the right finish for how you'll use it.

Why does GRP need dry weather?

The resin needs suitable temperature and dry conditions to cure properly. We plan installs around the forecast so the finish is sound.
