Our crews fit Trocal PVC membrane day in, day out, with every joint hot-air welded into a watertight seal. The detailing is what makes single-ply last, and it is what we get right.
A family firm since 1969, fitting flat roofs across Dublin on homes, extensions, and large commercial buildings. We know how a roof has to perform in our climate.
CSCS-carded operatives, an in-house safety officer, and full insurance cover so the work is done properly and safely from the first day to the last.
Trocal is a high-performance single-ply PVC roofing membrane and one of the longest-established single-ply names in Europe. It is laid as a single layer over the roof deck and hot-air welded at every joint so the whole roof becomes one watertight skin rather than a set of overlapping sheets that can work loose.
It is light, flexible, and well suited to flat and low-pitch roofs, and it can be specified for warm, cold, or inverted roof build-ups on both homes and commercial buildings. The welded membrane stands up well to wind-driven rain and the kind of weather an Irish roof has to take
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.
Membrane fixed back to the deck with screws and fasteners. The usual choice on larger commercial and industrial roofs.
The membrane is fully bonded to the substrate for a smooth, fixing-free finish with strong resistance to water.
Membrane laid loose and weighed down with gravel or stone, often used on flat commercial roofs.
A planted build-up over the membrane for a living roof, with drainage and aeration designed in.
A few recent repairs around Dublin. Real jobs, real homes.
Every Trocal roof starts with a proper look at the deck, the falls, and the existing detailing, so we fit the right system the right way. We agree on a fixed price in writing, prepare the deck, then lay the membrane and hot-air weld every joint into a continuous watertight skin, dressing it neatly into upstands, outlets, and gutters. When it is done, you get the paperwork, the guarantee, and a roof built to perform for the long term.
Not sure whether Trocal is right for your roof, or whether you need a new membrane, a recover or a repair? We will look at it and tell you honestly which one it needs, with a written, fixed price.
