Roof Repairs on Protected Structures and ACA Homes in Dublin

Dublin has thousands of Georgian, Victorian and Edwardian houses, and many of them are on a council's Record of Protected Structures or sit inside an Architectural Conservation Area (ACA). Dublin City Council's Record of Protected Structures alone lists thousands of buildings, from city-centre terraces to red-brick houses in Rathmines, Drumcondra and Clontarf.

If your home is one of them, a leaking roof still needs fixing quickly. But the way it is repaired matters more than on a modern house. Some works that would be routine elsewhere can need planning permission, and the wrong materials can damage the character of the building you are responsible for.

This guide explains what to check before roof work on a protected or ACA home in Dublin City, South Dublin, North Dublin, Bray, Wicklow and Naas, and how the current grant scheme can help with the cost. It is general guidance, not legal advice. Your local authority's Architectural Conservation Officer is the person to confirm what applies to your property.

Step 1: Find out if your house is protected

Do not assume. Period houses are not automatically protected, and some modest buildings are.

• Record of Protected Structures (RPS). Each council keeps an RPS as part of its development plan. Dublin City's is Volume 4 of the Development Plan 2022–2028. South Dublin, Fingal, Dún Laoghaire-Rathdown, Wicklow and Kildare publish their own.
• Architectural Conservation Areas. ACAs are mapped in the same development plans. A house in an ACA is not a protected structure, but works to its exterior can still be controlled.
• Your own paperwork. The Department's guide to historic roofs notes that a notice is sent to every owner and occupier when a building first becomes protected. Check your title documents or ask your solicitor if you bought recently.

If you are not sure, contact the conservation section of your council and ask. It costs nothing and avoids problems later.

Step 2: Understand what protection covers

Protection is wider than many owners expect. South Dublin County Council's protected structures page explains that it covers all parts of the structure, including its interior and the land around it, along with other structures on that land.

For roofs, the Department of Housing's Advice Series booklet Roofs: A Guide to the Repair of Historic Roofs sets out the key points:

• For a protected structure, the usual exemptions from planning permission may not apply. Works that would materially affect its character need planning permission.
• In an ACA, works to the exterior that would affect the character of the area need planning permission.
• Owners and occupiers must maintain the building and not allow it to fall into decay through neglect.
• Maintenance and repair carried out in line with good conservation practice may not need permission, but you should ask the Architectural Conservation Officer if you are in any doubt.

Planning law is also changing. The Planning and Development Act 2024 is being brought into force in phases, and South Dublin County Council notes that transitional arrangements may affect which rules apply. This is another reason to check with the council rather than rely on what a neighbour was told years ago.

Step 3: Ask for a Section 57 declaration if you need certainty

The owner or occupier of a protected structure can ask the planning authority for a Section 57 declaration. Dublin City Council's Section 57 page explains that it clarifies which works would be considered exempted development, and it provides the application form.

South Dublin County Council says it will generally respond within three months. That makes a declaration useful for planned repairs and re-roofing, but not for an emergency leak. If water is coming in now, ask your roofer for temporary protection that does not damage the historic fabric, and contact the council about the permanent repair.

Roof works that need extra care

These are the jobs where we most often see problems on older Dublin roofs:

The guide's general principle is to do as much as necessary but as little as possible: repair rather than replace, find the cause of a failure before repairing it, use techniques that can be reversed, and keep a record of the work for future owners.

Bats and nesting birds

Historic roofs are often home to roosting bats and nesting birds, and the Department's guide warns that in certain circumstances it can be illegal to disturb them. If you have seen bats around the roof or there are active nests at the eaves, mention it before work is booked so the timing and method can be planned, and seek advice from the National Parks and Wildlife Service where needed.

Grants: BHIS 2027 closes on 30 October 2026

The Built Heritage Investment Scheme (BHIS) is a government grant run through local authorities. According to the BHIS 2027 guidance booklet:

• It covers protected structures, proposed protected structures and structures in ACAs, among others.
• Eligible works include roof repairs (minor and more extensive) and repairs to rainwater goods such as gutters and downpipes.
• Grants range from €2,500 to €50,000, with most projects receiving less than €30,000, and public funding cannot exceed 80% of the project cost.
• You need a method statement, prepared by the contractor, architect or conservation professional you are working with, with photos of the current condition.
• Works can start when you receive the Notice of Approval, and successful applicants are announced in early January.

The deadline for BHIS 2027 applications is 30 October 2026, and South Dublin County Council sets it at 5pm that day. If you miss it, applications open each summer for the following year, so it is worth getting a roof survey and method statement ready well before then.

Larger projects with a community, public or clear residential benefit may suit the Historic Structures Fund, which South Dublin County Council lists as closing at 5pm on 27 November 2026.

A sensible order of work

1. Contain any active leak with temporary protection and buckets or towels inside. Do not go onto the roof yourself.
2. Confirm the status of the house with your council.
3. Get a roof survey with photos so you know what is failing and why.
4. Agree a repair approach with your roofer that reuses original materials where possible.
5. Check permissions, including a Section 57 declaration if the work is significant.
6. Look at grants before work starts, since BHIS works can only begin after approval.
7. Keep records of materials, photos and invoices for the council and for future owners.
