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.

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.
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.
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.
It shrugs off Irish rain and wind, handles standing water, and needs very little care once it’s down.
We lay new GRP roofs and re-cover tired ones, and we get the bits underneath right.
Most roof problems start small and quiet, then get expensive. If you have spotted any of these, it is worth getting them looked at before the next downpour.
We come out, get on the roof, and find exactly what is wrong.
You get a clear, itemised price. No call-out charge, no pressure.
Our own crew carries out the work, tidily and on the agreed
date.
We show you what we did and stand over the work.
We check the roof and the deck and tell you straight if the boards under the old covering need replacing first.
A clear written price covering any deck work, the GRP system, the trims, and the topcoat. No vague estimates.
We sort the deck, fit the edge trims, then lay the matting and resin and consolidate it so there are no weak spots.
We finish with the coloured topcoat, let it cure properly, clear the site, and leave you the paperwork and cover
A few recent repairs around Dublin. Real jobs, real homes.
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.

Learn to drive that van or take your name off itPosted on Google Susie vBTrustindex verifies that the original source of the review is Google. I haven’t used the services of this company but I have seen atrocious and dangerous driving by one of their vans. I have reported this to the guarda. 30/11/25 09:20 their van engaged in dangerous driving with another Volvo each trying to overtake. Both cars swerved at each other. Whilst stopped at a red light - with pedestrians at the light - their van accelerated from stationary through a red light to overtake the Volvo. Easily could have caused harm to all involved. I wouldn’t trust a company who acts like this on the road.Posted on Google Gavin KeaneTrustindex verifies that the original source of the review is Google. Company seems to be too busy to follow up on work requests. Called 3 times over the space of 3 weeks requesting a visit. Receptionist requested photos which i sent and was told the roofer would contact me. Never did. Waste of time.Posted on Google Amelia TaylorTrustindex verifies that the original source of the review is Google.

No call-out charge, no obligation. We’ll tell you honestly whether it needs repairing or replacing.
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.
Book a free, no-obligation inspection and we will tell you honestly what your roof needs.
