Roofers in Dún Laoghaire for Granite Victorian Homes

Steep slate roofs, cut-granite parapets and tall stacks above the harbour, taking the hardest maritime weather in Dublin. Restored in kind by a family-run roofer since 1989.

Stone Houses, Slate Roofs and Harbour Weather

Roofers in Dún Laoghaire face something they meet nowhere else in the county, granite. The Victorian and Regency terraces along Crofton Road, Royal Marine Road, Corrig Avenue and Northumberland Avenue were built in cut stone rather than red brick, three and four storeys tall, with steep natural-slate roofs, parapets of solid granite and chimney stacks standing high above everything around them.

They were built to last and they have, but they sit in the harshest maritime position in Dublin. Salt wind coming straight across open water works on the mortar and the lead year after year, and the height and pitch mean nothing on these roofs is a quick fix. Doing it properly takes hand-dressed lead let into the stone, mortar chosen for granite and a scaffold, and it starts with a free inspection and a written scope before anyone quotes a figure.

Why Granite Changes the Whole Job

When the harbour was built the town went up around it in stone, and that decision still shapes every roof job here two centuries later. Granite walls are thick, hard and unforgiving, so where the slate meets the parapet or a stack the lead has to be cut and dressed into the stone by hand rather than sealed across it. Get that detail right and it lasts a lifetime, get it wrong and the water simply tracks behind the stone where nobody can see it.

The rest follows the same logic. Repointing wants a mortar that suits granite rather than a hard modern mix that traps damp in the joints, hidden parapet gutters need re-lining in proper code lead with real falls, and the slate wants re-hanging on fixings that will survive salt air. It is the most demanding restoration work we do, closer in craft to our Georgian roof restoration than to a standard suburban re-roof.

The Faults That Bring Us to Dún Laoghaire

Height, pitch and pure salt exposure combine here in a way they do not anywhere else we work. These four account for most of our calls.

Lead Failing Where Slate Meets Granite

A granite house moves and weathers differently to brick, and the lead flashing dressed into those stone joints takes the strain. Along Crofton Road and Royal Marine Road that junction is where the harbour weather gets in first, quietly, behind two feet of solid stone.

Steep Slopes Taking the Full Harbour Blow

The tall Victorian terraces stepping up from the seafront carry steep slate roofs with no shelter from anything. Wind coming across open water hits them squarely, and once a fixing lets go on a pitch that steep the slate does not slide, it leaves.

Tall Stacks Scoured by Salt Wind

These houses were built with serious chimney stacks standing well above an already tall roofline. Decades of salt-laden wind eat the mortar, crack the flaunching and loosen the pots, and at that height above Corrig Avenue it is scaffold work rather than a ladder and a hope.

Hidden Parapet Gutters Behind the Stone

Many of the grander terraces hide their gutters behind a cut-granite parapet, out of sight from the street. The lead lining fatigues, the outlets block with salt grit and debris, and the overflow soaks into the stone and the plasterwork rather than running away.

Roofing Services Around the Harbour and Beyond

It begins with a free inspection and a written scope, because on a house this tall the honest difference between a gutter re-line and a full restoration is real money. The work itself spans slate and tile roofing on the steep pitches, chimney repairs on stacks that need scaffold access, roof repairs for contained faults, and full re-roofing where a covering has finally gone. After a storm off the bay there is emergency roof repair when you need someone the same day.

Since so much here turns on hidden drainage, the guide to parapet and valley gutter leaks explains what to look for inside the house when the roof looks fine from the road. Guide prices are on roofing costs in Dublin, the free roof health check is a sensible first step, and we cover neighbouring Blackrock and the wider south county Dublin area too. When the house deserves a proper answer, roofers in Dún Laoghaire are one free inspection away.

Good to know

Dún Laoghaire Roofing, Answered

How far around Dún Laoghaire do you cover?
The town and everything around it. That means Crofton Road, Royal Marine Road, Corrig Avenue, Northumberland Avenue and Mulgrave Street in the centre, and out through Sandycove, Glasthule, Monkstown and Glenageary. Every job starts with a free inspection and a written quote, and access on the steeper streets gets planned into the price up front.
Is a granite house different to work on than a red-brick one?
Yes, chiefly at the junctions. Stone walls are thicker and less forgiving than brick, so the lead has to be dressed and let into the granite properly rather than sealed over with mastic, and repointing wants a mortar that suits the stone. It is slower, more skilled work, and doing it the quick way is why so many of these houses leak again within a year.
Our roof is very steep and very high. Does that add much to the cost?
It adds scaffolding and time rather than complication. A steep four-storey terrace above the harbour needs a proper scaffold for anyone to work safely, so we price that in from the start and use the access to survey and sort everything at once rather than coming back twice.
Do you work on protected structures and seafront terraces?
Regularly. A great deal of the Victorian and Regency housing here is protected, and the approach suits it anyway, natural slate, hand-dressed lead and the right mortar for the stone. Where consents or a conservation professional are involved we work alongside them and keep the written scope matched to what has been approved.
