Do I Need Planning Permission for a New Roof in the UK? [Back to Blog](/blog) 28 February 2026 5 min read # Do I Need Planning Permission for a New Roof in the UK? One of the most common questions UK homeowners ask before starting a roof project is whether they need planning permission. The good news is that most roof replacements don't require it — but there are important exceptions you need to be aware of. ## When You DON'T Need Planning Permission A like-for-like roof replacement — where you're replacing the existing roof with the same or similar materials without changing the shape or height — generally falls under **permitted development rights**. This means you can proceed without applying for planning permission. This covers: - Replacing tiles with tiles of the same type and colour - Replacing felt flat roofing with a modern equivalent - Installing a new breathable membrane - Replacing battens and minor timber repairs - Ridge tile replacement ## When You DO Need Planning Permission You'll typically need planning permission if: - **You're changing the roof height** — raising or lowering the roof line - **You're adding dormers** — these change the external appearance - **You're changing the roof shape** — e.g., from pitched to flat - **You're using very different materials** — e.g., changing from slate to metal - **Your property is listed** — you'll need listed building consent - **You're in a conservation area** — additional restrictions apply - **Permitted development rights have been removed** — check with your local council ## Building Regulations Even when planning permission isn't required, **building regulations may apply**. If you're re-roofing more than 25% of the roof area, you may need to comply with Part L (energy efficiency) regulations, which could mean adding insulation. Your roofer should be able to handle building control notification if they're registered with a competent person scheme like Competent Roofer or NFRC. ## How to Check - Contact your local council's planning department - Check the Planning Portal (planningportal.co.uk) - Ask your roofer — experienced contractors will know the local requirements - Consider a pre-application enquiry if your situation is complex ### Instant Roof Cost Calculator Complete every field to reveal your 2026 estimate Property / Roof Type Terraced house (~50 m²) 3-bed semi-detached (~65 m²) Detached (~85 m²) Bungalow (~90 m²) Single garage roof (~15 m²) Extension / flat roof (~25 m²) Enter my own m² Material Concrete Tiles Clay Tiles Natural Slate Synthetic Slate EPDM Rubber (Flat) GRP Fibreglass (Flat) 3-Layer Felt (Flat) Tile Type Standard interlocking Plain / small format Handmade / heritage Lightweight synthetic N/A — flat roof system Roof Complexity Simple (gable, no chimneys/dormers) Standard (hip roof, 1 chimney) Complex (dormers, valleys, 2+ chimneys) Location (UK Region) London South East South West East of England East Midlands West Midlands Yorkshire & Humber North West North East Wales Scotland Northern Ireland 📱 Enter your first name, phone number and postcode so we can send your estimate by SMS.
