Fibreglass Roofing in Dublin

Fibreglass, or GRP, is the tough, modern way to do a flat roof. Glass matting and resin are laid over a solid deck and cured into one continuous waterproof layer with no joints or seams to leak. It’s strong enough to walk on, lasts for decades, and suits extensions, garages, dormers, and balconies. Laid properly by a family firm of roofers since 1969.

Why fibreglass

What a GRP roof gives you

Fiberglass has become one of the most popular flat-roof choices in Ireland, and it’s easy to see why once you know how it works.

One continuous layer

Laid wet and cured solid, a fibreglass roof has no joints or seams, so there are far fewer places for water to ever get in.

Strong and walk-on

A hard, durable surface you can walk on, which makes it ideal for balconies, terraces and any roof you need access to. Non-slip finishes available.

Long-lasting, low upkeep

It shrugs off Irish rain and wind, handles standing water, and needs very little care once it’s down.

What's included

Our fibreglass roofing service

We lay new GRP roofs and re-cover tired ones, and we get the bits underneath right.

  • New GRP flat roofs and re-covers, in a colour and finish to suit
  • Extensions, garages, dormers, bay windows, porches, balconies and terraces
  • A sound deck first, OSB or plywood, replaced where the old one’s soft or rotten, because a fibreglass roof is only as good as the deck under it
  • GRP edge trims, upstands, and neat detailing around pipes, outlets and rooflights
  • Non-slip finishes for walk-on areas like balconies and terraces
  • Recoating to refresh and extend an older GRP roof
  • Honest advice on whether fibreglass or another flat-roof system suits your roof
  • A written, fixed price before any work, and workmanship cover

Deck, trim & lay GRP

We sort the deck, fit the edge trims, then lay the matting and resin and consolidate it so there are no weak spots.

Topcoat & sign-off

What it costs

Fibreglass roof cost in Dublin

Fibreglass costs more than a basic felt roof, but it lasts far longer and needs almost no upkeep, so over the years it tends to be the better value on a roof you want to last. What moves the price is the area, the state of the deck (replacing rotten boards is the common added cost), the complexity (upstands, trims, rooflights, and balconies all add work), and the access. See our fiberglass cost guide, then book a free survey for a fixed price in writing.

What affects the price

  • Roof area
  • Condition of the deck (any board replacement)
  • Upstands, trims, rooflights and outlets
  • Walk-on / non-slip finishes
  • Access and stripping the old covering

FAQS

Frequently Asked Questions

Direct answers from an experienced, hands-on roofing professional.

It’s a flat-roof system made by laying glass matting and liquid resin over a solid deck, which cures into one hard, continuous waterproof layer finished with a colored topcoat. There are no joints to fail, and you can walk on it.

A well-laid GRP roof lasts for decades with very little maintenance, and a recoat down the line extends it further. We’ll give you a realistic lifespan for your roof at the survey.

Yes. It’s a hard, strong surface, which is why it suits balconies and terraces. We can add a non-slip finish where you’ll be walking on it regularly.

It needs a dry spell, because the resin has to cure properly. We plan the job around the weather and won’t rush it on, since a fibreglass roof rushed in the wet is a fibreglass roof that fails.
