Roofing in a conservation area or on a listed building

If your home is in a conservation area, small like-for-like roof repairs are usually fine, but changing the roof materials, adding roof windows or building a dormer may need planning permission. If your home is listed, most roof work beyond very minor like-for-like repairs needs listed building consent, and doing unauthorised work to a listed building is a criminal offence. Always speak to your council's conservation officer before work starts.

Conservation areas: what changes

A conservation area is an area the council has protected because of its special character. Your home does not have to be old or listed to be inside one. The main effect on roof work is that some "permitted development" rights are reduced.

Usually fine without permission

• Like-for-like repairs: refixing slipped tiles or slates, replacing broken ones with matching materials, repointing ridges, renewing flashings in lead
• Re-roofing in the same materials so the roof looks the same

Often needs planning permission

• Dormers. Permitted development rights for loft extensions and dormers do not apply in conservation areas, so a dormer needs planning permission.
• Changing materials. Swapping natural slate or clay tiles for concrete tiles, or any change that alters the look of the roof.
• Roof windows, especially on roof slopes facing the road.
• Anything covered by an Article 4 direction. Councils can use these to remove permitted development rights in a conservation area. Typical examples include changing the roof covering, adding rooflights on the front, and taking down chimneys.

Each council publishes maps of its conservation areas and any Article 4 directions, so you can check online or ask the planning team.

Listed buildings: what needs consent

A listed building is protected as a building of special architectural or historic interest. Listed building consent is needed for any work that affects its character, inside or out, and the roof is often a key part of that character.

• Very minor repairs may not need consent, but only if they are truly like for like in every respect: materials, size, design, method and finish.
• Larger repairs and re-roofing usually need consent. Some councils say that affecting more than half of any single roof slope will need an application.
• Changing materials, such as replacing handmade clay tiles with machine-made ones, or using a different slate, needs consent.
• New roof windows, dormers, vents or solar panels need consent and often planning permission too.

Getting consent: the steps

1. 1Check the status of your home. Historic England's National Heritage List for England shows whether a building is listed, and your council can confirm conservation areas and Article 4 directions.
2. 2Talk to the conservation officer about what you want to do, before you commit to any work.
3. 3Apply with the right detail. Councils usually want drawings, photos and a clear description of the materials and methods.
4. 4Wait for the decision before work starts.

There is no fee for a listed building consent application. Carrying out work without consent when it is needed is a criminal offence, and the council can require the work to be put right. The safest step is to talk to your council's conservation officer before you agree any work.

Getting the materials and methods right

On older roofs, the details matter as much as the paperwork:

• Reuse what you can. On many old clay tile and slate roofs, the tiles themselves are fine; it is the nails, pegs and battens that have worn out. Carefully stripping, saving and relaying the good tiles keeps the roof's character.
• Match carefully. Replacement tiles and slates should match in colour, size, texture and thickness.
• Use traditional leadwork for valleys, flashings and chimneys where that is what the roof had.
• Think about breathability. Old buildings often rely on air moving through the roof. Breathable underlays and the right ventilation help avoid trapping moisture.

Building regulations and other rules still apply

Planning permission and listed building consent are separate from building regulations. A re-roof may still need building regulations approval, including insulation upgrades, although building control can take a flexible approach on historic buildings where upgrades could cause damage. See our guide to building regulations when you re-roof.

Bats often roost in older roofs. All bat species and their roosts are protected, so if you think bats use your roof, get advice before work starts. For the general rules that apply to every home, see do I need planning permission for roof work?.

In Essex, Hertfordshire and Cambridgeshire

The three counties have some of the finest historic towns in England, and many homes sit within conservation areas or are listed.

• Saffron Walden has 373 listed buildings, and its centre is full of timber-framed and brick buildings with steep handmade clay plain tile roofs.
• Thaxted and Coggeshall both have conservation areas and a great many listed buildings, where the pegs and nails on old clay tile roofs wear out and tiles slip.
• St Albans has 19 conservation areas across the city and district, and Article 4 directions in parts of the centre.
• Much of central Hertford is a conservation area, with old timber-framed and brick buildings around Fore Street and the castle.
• In Wisbech, Georgian and Victorian buildings often have parapets, hidden gutters and lead valleys behind the front walls, which can block and leak without being seen from the street.
• Godmanchester has a historic centre with a large number of listed buildings, and homes near the river sit in damper air that encourages moss.
