Do I need planning permission to replace my roof like-for-like?

Why does a like-for-like re-roof not usually need planning permission?

A like-for-like re-roof usually needs no planning permission because the law does not count it as development. Section 55 of the Town and Country Planning Act 1990 says works of maintenance, improvement or other alteration that do not materially affect the external appearance of a building are not development, and only development needs permission.

Houses also have a second route. Class C of the General Permitted Development Order 2015 grants permitted development rights for other alterations to a house roof, and the government's householder technical guidance gives re-roofing as its example. Class C only applies within these limits:

• The work must not protrude more than 150 mm beyond the plane of the original roof slope.
• No part can be higher than the highest part of the original roof.
• Chimneys, flues, soil and vent pipes and solar panels are outside Class C and have separate rules.
• A window on a side-facing roof slope must be obscure-glazed, and must not open unless the opening part is more than 1.7 m above the floor.

If you add insulation above the rafters, check the finished surface against these limits. This page covers England only, as the 2015 Order applies to England.

When does replacing a roof need planning permission or consent?

You need to apply when the house is listed, or when the new roof will look materially different and no permitted development right covers it.

Listed buildings

Listed building consent is separate from planning. Section 7 of the Planning (Listed Buildings and Conservation Areas) Act 1990 requires consent for any alteration that would affect a listed building's character, and section 9 makes unauthorised work a criminal offence, with up to two years in prison on indictment. City of York Council says minor repairs using matching materials and techniques do not need consent, and that there is no fee to apply. That wording covers minor repairs, so ask the council before stripping and re-covering a whole listed roof.

Article 4 directions

A council can withdraw permitted development rights in some or all of its area by making an Article 4 direction, often in a conservation area. The North York Moors National Park Authority leaflet shows how this reaches roofs. Where its direction applies, planning permission is needed for changes to roof design, materials or profile on elevations facing a highway, waterway or important open space. Its examples include changing pantiles to concrete tiles, and changing a slate roof laid in diminishing courses to a plain slate roof. The same leaflet says like-for-like repair needs no consent.

Flats and some converted or new-build homes

Householder permitted development rights do not apply to flats or buildings containing flats. Class C also excludes homes created through certain permitted changes of use, and homes built under the Part 20 new dwellinghouse rights. A condition on the house's original planning permission can also remove these rights.

Changing the roof's shape or height

Raising any part of the roof above the original highest point takes the work outside Class C. Dormers fall under Class B, which has its own limits, and anything outside both needs a householder application. A full new roof with the same shape and look stays within the normal rules.

What counts as like-for-like on a Yorkshire roof?

Like-for-like means the new covering looks the same as the old: matching material, colour, size and the way it is laid. The legal test is whether the change would materially affect how the building looks.

Natural slate or stone slate replaced with concrete tiles, graduated courses replaced with slates of one size, and clay pantiles replaced with concrete all change how a roof looks from the street. The North York Moors leaflet names two of these.

On a Victorian terrace with Welsh slate, matching natural slate keeps a slate re-roof inside the like-for-like rules. On older Pennine houses, stone slate roofs laid in diminishing courses need the same sizes and coursing put back.

How can you check before the old roof comes off?

Ask your council before the work starts, and get the answer in writing if there is any doubt.

1. Ask whether the house is listed or covered by an Article 4 direction.
2. Check the original planning permission for the house for any condition removing permitted development rights.
3. If you want certainty, apply to the council for a Lawful Development Certificate. The government's technical guidance gives this as the way to be certain that proposed work is lawful and needs no planning application.
4. Treat Building Regulations as a separate question. The government's technical guidance says permitted development rights do not remove Building Regulations requirements, and our re-roofing and Building Regulations guide explains that side.
