Period Roof Restoration in Dublin
Many older Dublin roofs still use the materials and details they were originally built with: natural slate on timber, lead at the junctions, and rainwater carried in parapet, box and secret gutters rather than over the edge. Roofs like these can usually be repaired and restored rather than stripped, as long as the slate, leadwork and structure are still serviceable, and they tend to reward being looked after.
We restore and re-roof period houses across the city — Victorian and Edwardian terraces, Georgian buildings, and the returns, valleys, parapets and stacks that come with them. The starting position is always repair where repair is genuinely viable, because a sound original slate roof is worth keeping and the details are the part that fails first.

What brings us to a period roof
- Slates slipping in numbers, with nail heads corroded through — often called nail sickness
- Slate that is delaminating, flaking at the edges or breaking when handled
- Leaks at a parapet, box or secret gutter that has been patched before
- Failed or split leadwork at valleys, abutments, chimneys and flat parapet sections
- Chimney stacks with eroded pointing, loose flaunching or defective flashing
- Sagging or dipping along a slope, ridge or valley line
- Repeated repairs on the same roof that have stopped holding
How we approach the job
1.Establish whether the roof can be repaired
Slipping slates with sound slate is a fixing problem; failing slate is a covering problem. That distinction decides everything that follows, and it cannot be made from the ground.
2.Keep the character of the roof
Slate size, coursing, the line of the eaves and the way details were originally formed all matter on a period house. Where slates are replaced they are matched to the existing roof as closely as available materials allow.
3.Treat the leadwork as leadwork
Valleys, parapet gutters, soakers, aprons and stack flashings are formed in lead to appropriate detail, with the joints and laps the material needs rather than sealant across a failure.
4.Expect the unexpected, and agree it first
Opening up an old roof sometimes reveals rot at a rafter foot, a failed gutter sole or earlier work that was never right. We explain what has been found and agree any additional work and cost with you before proceeding.
Nail sickness: the usual verdict
On many Victorian and Georgian roofs the slate itself is still serviceable and the nails have corroded away. Slates then slip in ones and twos across the whole roof, and refixing individual slates becomes an endless job. Where the slate is sound it can often be stripped, sorted and re-laid on new fixings, which keeps the original material on the building.
Parapet, box and secret gutters
Period buildings frequently drain into a concealed gutter behind a parapet or between roof slopes, rather than to an eaves gutter. They carry a great deal of water, they are out of sight, and when the lining fails the water goes directly into the structure. They are among the most common sources of serious damage on period roofs, and they need forming properly rather than patching.
Chimneys on old stacks
Tall Georgian and Victorian stacks take weather from every side. Eroded pointing, cracked flaunching and lead flashing that has lifted or been bedded badly account for a large share of period roof leaks. Chimney repairs and lead flashing cover that work.
Ventilation and modern underlays
Older slate roofs often allowed a good deal of air movement through the covering and the construction around it. A re-roof that introduces a modern underlay, along with added insulation and a tighter house, can change how the roof space behaves, so the ventilation path needs to be considered as part of the work rather than afterwards — see roof ventilation.
What we are, and what we are not
We are roofing contractors working on period buildings. Where a property is a protected structure, or where planning, conservation approval, structural engineering or a building surveyor's opinion is required, that sits with the appropriate professional and we will say so rather than advise on it ourselves.

FAQ
Period Roof Restoration — common questions
Can my old slate roof be repaired rather than replaced?
Often, yes. If the slate is sound and the fixings have gone, the roof can frequently be stripped and re-laid using the original slate with new fixings. If the slate itself is delaminating and breaking, repair stops being viable. That judgement needs the slate handled, not viewed from the ground.
Will replacement slates match the existing roof?
We match size, colour and coursing as closely as the available materials allow, and salvaged slate is used where it is sound and suitable. An exact match to a hundred-year-old quarry is not always possible, and we will be straight with you about that before work starts.
What is a secret or box gutter?
A concealed gutter, usually lead-lined, running behind a parapet or between roof slopes instead of at the eaves. They are common on period Dublin buildings, they are invisible from the street, and a failure in one puts water straight into the structure.
Do you work on protected structures?
We carry out roofing work on period buildings, including natural slate and leadwork. Where a building is protected, the consents and conservation requirements are matters for the owner and the appropriate professionals — we work within what has been approved rather than advising on it.
Why does period roof work cost more than a modern re-roof?
Access on tall terraced houses, the amount of hand-formed lead detailing, concealed gutters, chimney work and the care needed with original material all add time. What drives the cost is explained in our roof replacement and repair-versus-replacement guides.
