Permitted Development Rules for a Roof Replacement (Like for Like)
Generally permitted. Like-for-like roof replacement using the same or very similar materials is considered routine maintenance and repair and does not need planning permission. This includes replacing tiles, slates, felt, and flashings.
Conditions
- 1Replacement materials should be the same as, or similar in appearance to, the existing materials
- 2The roof shape, pitch, and height must not change
- 3No structural alterations that would change the roof profile
- 4Scaffolding may require a temporary licence if erected on a public highway
Size and Dimension Limits
- No change to existing roof dimensions
When Permitted Development Does Not Apply
- Listed buildings require listed building consent even for like-for-like repairs
- In conservation areas, the LPA may have Article 4 directions restricting roof material changes
- If adding insulation or changing the roof structure, Building Regulations may apply
What About Building Regulations?
Building regulations approval is not usually required
Like-for-like roof replacement does not normally require Building Regulations approval. However, if you are re-roofing more than 25% of the roof area (or more than a single slope on a pitched roof), Part L (thermal insulation) requirements may be triggered, requiring additional insulation to be added.
Building regulations are separate from planning permission. Even if your project is permitted development, you may still need building regulations approval. Contact King's Lynn and West Norfolk building control or use an approved inspector.
How to Apply in King's Lynn and West Norfolk
If you need planning permission for your roof replacement (like for like), you can apply through King's Lynn and West Norfolk's planning department or via the national Planning Portal.
If your project is permitted development and you want written confirmation, you can apply for a Lawful Development Certificate (LDC) from King's Lynn and West Norfolk. This provides proof that your project does not need planning permission, which can be helpful when selling your property.
What Happens If I Build Without Permission?
Very low risk for genuine like-for-like replacement. Enforcement is only likely if the work changes the appearance of the roof or is on a listed building without consent.
