The short answer
Most like-for-like re-roofs do not need planning permission — they usually fall under permitted development. You are more likely to need it if you change the roofline (such as adding a dormer), significantly alter the appearance or materials, or if the property is listed or in a conservation area, National Park or area of outstanding natural beauty. Planning permission is separate from Building Regulations, which most full re-roofs do need. When in doubt, check with your local planning authority before work starts.
Planning permission worries many homeowners facing roof work, but for the most common job — replacing a worn covering with a similar one — it usually does not apply. Planning is concerned with how a building looks and affects its surroundings, so it bites when the work changes the roof's appearance or shape, or where the property sits in a protected setting. This guide explains when permission is and is not needed, and where the exceptions lie. It is general information; your local planning authority is the definitive source for your property.

- Listed building listed building consent likely
- Conservation area extra restrictions apply
When you usually do not need permission
For the great majority of homeowners, re-roofing is covered by permitted development — rights that allow certain works without a planning application. This typically includes replacing a worn-out covering with a similar one, repairing or re-covering a roof, and minor maintenance. As long as you are not materially altering the roof's shape or appearance, and the property is not in a protected category, a standard re-roof generally proceeds without planning permission. You will still usually need to satisfy Building Regulations, which is a separate matter.
When you are more likely to need permission
Permission becomes more likely when the work changes the roof rather than simply renewing it:
- Adding a dormer or otherwise raising or extending the roofline.
- Changing the roof shape — for example altering the pitch or converting to a different form.
- A significant change of materials or appearance that affects the look of the building.
- Roof terraces or balconies formed in the roof.
- Work that exceeds the limits and conditions attached to permitted development rights.
Listed buildings and conservation areas
If your home is listed, almost any external work — including re-roofing — is likely to need listed building consent, and you may be required to match the original materials exactly (for example reclaimed slate rather than concrete tile). In a conservation area, permitted development rights are often restricted, so changes that would be allowed elsewhere may need permission, and material choices can be controlled to preserve the area's character. The same heightened scrutiny applies in National Parks and areas of outstanding natural beauty. In all of these, the safe step is to contact the local planning authority before committing to the work or the materials.
How to check for your property
The definitive answer always comes from your local planning authority (your council's planning department). You can also use the GOV.UK Planning Portal for general guidance on permitted development and roof alterations. If you want certainty before starting, you can apply for a Lawful Development Certificate, which confirms in writing that your proposed work does not need planning permission. A good roofer will be familiar with the local position, but the responsibility for confirming planning status rests with the property owner.

Frequently asked questions
Do I need planning permission to replace my roof?
Usually no, if it is a like-for-like replacement that does not change the roof's shape or appearance — this normally falls under permitted development. You are more likely to need permission for dormers, roofline changes, significant appearance changes, or if the property is listed or in a conservation area. You will still usually need Building Regulations approval.
Can I change my roof tiles to a different type without permission?
A change of material that does not significantly alter the appearance is often permitted, but a significant change to the look of the roof can need planning permission, and in conservation areas or on listed buildings material choices may be controlled. Check with your local planning authority before changing to a noticeably different covering.
Is planning permission the same as Building Regulations?
No. Planning permission is about appearance and impact on surroundings; Building Regulations are about safety and performance, such as insulation and structure. Most like-for-like re-roofs do not need planning permission but do need to satisfy Building Regulations, principally Part L.
