Do I Need Planning Permission for a New Roof?

In most cases, no. Replacing a roof with the same or similar materials is usually permitted development, so no planning permission is needed. Permission is required for listed buildings, flats, many conservation-area homes, or if you change the roof’s shape or height. Building Regulations, however, apply to almost every re-roof.

The short answer: most re-roofs don’t need planning permission

For the vast majority of homes in Sunderland and the wider North East, replacing a worn-out roof is treated as permitted development. That means if you’re re-covering the roof with the same or very similar materials — for example, swapping tired concrete tiles for new ones of a similar profile — you can usually go ahead without a planning application. The key word is like-for-like: you’re repairing or renewing the roof, not changing its shape, height or appearance.

This is the situation most homeowners are in when they’re looking at a full roof replacement after years of patch repairs. If you’re still weighing up whether you even need a new roof yet, our guides on the signs you need a new roof and repair vs replace are a good place to start.

When you DO need planning permission

Permitted development rights don’t apply to everyone. You will normally need planning permission — or a separate consent — in these situations:

• Listed buildings. Any work to a listed building, including re-roofing, needs Listed Building Consent. This applies to every grade (I, II* and II). Doing the work without consent is a criminal offence, so check first.
• Flats and maisonettes. These don’t have permitted development rights. Altering the roof of a flat almost always needs a full planning application.
• Conservation areas. Like-for-like repairs are usually still fine, but if you change to a materially different material (e.g. swapping natural slate for concrete tile), the council may require prior approval.
• Changing the shape, height or pitch. Raising the ridge, altering the slope, or adding a dormer or loft conversion goes beyond a simple re-roof and typically needs permission.
• New rooflights that project too far. Standard conservation rooflights are usually fine, but anything that sticks out more than 150mm from the slope, or sits above the highest part of the roof, can need an application.

Planning permission vs Building Regulations — they’re not the same

This is where a lot of homeowners get caught out. Even when you don’t need planning permission, your re-roof almost certainly needs to comply with Building Regulations. They’re two separate systems: planning controls what a building looks like and how it affects its surroundings; Building Regulations control how it’s built and how safe and efficient it is.

The big one for re-roofing is Part L (Conservation of Fuel and Power). Under the rules tightened in 2022, if you replace 25% or more of a roof — which covers virtually every full re-roof — you usually have to bring the whole roof up to current insulation (U-value) standards. In practice that means adding or upgrading insulation as part of the job, not just relaying the tiles. A reputable roofer will build this into the quote and arrange the necessary Building Control sign-off.

At a glance: do you need permission?

Your situation	Planning permission?	Building Regs?
Like-for-like re-roof, ordinary house	Usually no (permitted development)	Yes — typically Part L applies
House in a conservation area, different material	Often needs prior approval	Yes
Listed building (any grade)	Yes — Listed Building Consent	Yes
Flat or maisonette	Usually yes	Yes
Changing shape/height, adding a dormer	Usually yes	Yes

Indicative guidance only — rules vary by property and area. Always confirm with Sunderland City Council’s planning department or check the government Planning Portal for your specific case.

What about solar panels, flat roofs and conservatories?

Adding solar panels to a pitched roof is usually permitted development, provided the panels don’t project more than 200mm and sit below the highest part of the roof — though listed buildings and some conservation areas are exceptions. Replacing a flat roof like-for-like is generally permitted development too, but the same Building Regs insulation rules apply. Converting a cold, leaky conservatory to a warm roof can sometimes need building control sign-off depending on the design, so it’s worth checking before you start.

How much does this add — and how long does it take?

A standard Lawful Development Certificate application in England costs an indicative £150–£250 in council fees and can take roughly 6–8 weeks to be decided. Full planning applications for householder work cost more (indicatively around £250+) and typically take 8 weeks or so. Building Control fees for a re-roof are usually a few hundred pounds and are often handled by your roofer through a registered scheme. These are general UK ranges, not quotes — for an exact price on your roof you’ll need a free survey. You can see our broader roof cost guide for how the roofing work itself is priced.

Our honest advice

For most Sunderland homeowners replacing a worn roof with similar materials, you won’t need planning permission — but you will need to meet Building Regulations, especially on insulation. If your home is listed, in a conservation area, a flat, or you’re changing the roofline, check before you commit. When there’s any doubt, a Lawful Development Certificate gives you legal proof the work was permitted, which is handy when you come to sell. We’re happy to talk through what your specific job needs, and we handle the Building Control side as part of the work.
