Do I Need Planning Permission for Roof Work?
Most straightforward reroofs don't need planning permission — but several common roof jobs do, and conservation areas and listed buildings change the answer entirely.
- Like-for-like reroof: usually permitted development
- Changing the covering type: check first
- Dormers and roof extensions: usually need permission
- Conservation areas restrict permitted development
- Listed buildings need listed building consent
- Building Regulations apply even when planning doesn't
Planning and Building Regulations are different things
Planning permission is about appearance and impact; Building Regulations are about construction standards. A reroof that needs no planning permission at all will still normally need to meet Building Regulations for structure, insulation and weathertightness, notified either through a competent person scheme or a building notice to your council.
The jobs that usually do need permission
Dormer construction, raising the ridge, significant alterations to the roof shape, and — in many conservation areas — changing the material or the appearance of the front roof slope. Solar panel installations are often permitted development but have their own conditions, particularly on listed buildings and in conservation areas.
- ▸Dormers and roof enlargements
- ▸Changing roof shape or ridge height
- ▸Front-elevation changes in conservation areas
- ▸Any external alteration to a listed building
How we handle it
At survey we tell you which category your job falls into and, where it's borderline, we recommend a pre-application check with your local planning authority rather than assuming. Where the work is notifiable under Building Regulations we handle that notification as part of the job and give you the certificate at the end — it's what a buyer's solicitor will ask for later.
FAQs
Is a like-for-like reroof permitted development?+
For most houses, yes — but permitted development rights can be removed by an Article 4 direction or by a planning condition on newer estates, so it's worth a check.
Does changing from slate to tile need permission?+
Sometimes, particularly in conservation areas or where a planning condition specifies materials. We'll flag it before quoting.
What about a flat roof replacement?+
Rarely a planning matter, but a Building Regulations one — thermal upgrade requirements usually apply when the covering and deck are replaced.
