Mastic asphalt is the tough, traditional way to waterproof a flat roof. Poured and laid hot into one continuous finish, it stands up to weather and to foot traffic better than almost anything else. We install, repair, and recoat asphalt roofs on homes, extensions, and commercial buildings across Dublin. A family firm of roofers since 1969.

A family firm since 1969, with asphalt laid across Dublin on homes, extensions, and commercial roofs. We know how the material behaves in our climate.
CSCS-carded operatives, an in-house safety officer, and full insurance coverage so the job is done properly and safely from the first day to the last.
Flat roofs fail first at the edges. We take care at the upstands, outlets, and gutter lines, the points that decide whether a roof stays dry.
Mastic asphalt is a blend of bitumen and fine aggregate, heated and laid hot in layers over the roof deck. As it cools, it sets into one tough, continuous, waterproof surface with no joints or laps to lift or split. That continuous finish is what makes it so reliable on flat and low-pitch roofs in our wet, windy climate. It is also hard enough to walk on, which makes it a strong choice for balconies, walkways, dormers, and any flat roof that needs to take regular foot traffic.
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.
New asphalt roofs laid to last on extensions, garages, and full builds.
Cracks, blisters, and failed detailing are put right to stop leaks at the source.
Protective recoats that refresh and extend the life of a sound asphalt roof.
Hard-wearing asphalt for offices, units, and public buildings, fitted around your operation.
A few recent repairs around Dublin. Real jobs, real homes.
Every asphalt roof starts with a proper look at the deck, the falls, and the existing detailing so the finished surface drains the way it should. We agree on a fixed price in writing, prepare the deck, then lay the asphalt hot to the correct thickness, building up the upstands and dressing it neatly into outlets and gutters. When it is done, you get the paperwork and a roof that needs very little looking after.
Not sure whether your flat roof needs a repair, a recoat, or a full new asphalt finish? We will look at it and tell you honestly which one it needs, with a written, fixed price.

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.
Yes. Asphalt sets into one continuous waterproof surface with no joints to fail, which suits our wet, windy weather. It is also hard-wearing and takes foot traffic well, so it is a common choice for balconies, walkways, and busy commercial flat roofs.
Mastic asphalt is a mix of bitumen and fine aggregate. It is heated and laid hot in layers over the deck, and then it cools and sets hard into a single continuous waterproof finish. Laying it well is skilled work, which is why it pays to use an experienced asphalter.
Often it can be repaired or recoated rather than fully replaced. We look at the roof first and only recommend a new finish when a repair is no longer the sensible option. We will tell you honestly which one your roof needs.
Anywhere you want a tough, long-lasting flat roof that can take some traffic, such as balconies, walkways, dormers, garages, extensions, and commercial flat roofs. If your roof is large and modern, we will also talk you through single-ply options so you can compare.
