Home > FAQs > Do you need planning permission to replace your roof tiles with like for like tiles in a Conservation Area?
This is assuming the house is a single dwelling, not listed and not in an Article 4 designated area.
In short, yes, in a conservation area you should assume that planning permission is required, even where the replacement roof tiles are intended to match the existing ones and appear visually the same.
For a single dwelling outside a conservation area, replacing roof tiles on a like for like basis is normally treated as repair or maintenance and does not require planning permission. The position changes in a conservation area because permitted development rights are restricted. Roof works are specifically more sensitive, as the roof is considered a key element of the character and appearance of the building and the wider area.
Even if the new tiles are very similar, a change in material, finish, colour tone, texture or profile can be classed as a material alteration rather than a repair. Councils often take the view that if the tiles are not identical to the originals, permission is required. This is particularly the case where the originals are natural slate, clay tiles or historically distinctive materials, or where the replacement tiles are modern equivalents.
The same applies to the replacement of windows to a property in a conservation area. If the property is listed, you will need listed building consent to replace windows even like-for-like or to change the glazing. If the property is not listed but is situated in a conservation area, planning permission is only required if the proposal will change the appearance of the property. The exception is if the windows are timber framed and you apply to change the windows to upvc or composite that have the same grain and appearance as timber framed. In this scenario planning permission is still required.
In practice, some councils will exercise discretion if the replacement tiles are genuinely indistinguishable and the works are clearly necessary due to failure of the existing roof covering or wear and tear. However, that discretion cannot be relied upon, and enforcement risk does exist, especially following neighbour complaints or future planning applications. Also if the property is listed, you will need to obtain the council’s approval including listed building consent.
The safest approach in London and around the UK is either to apply for planning permission or to seek written confirmation from the council, for example via a lawful development certificate or pre application advice, confirming that permission is not required. This provides certainty and avoids issues later when selling or extending the property.

A true repair is a part of the property which is damaged, such as a window which is rotten and without fixing it the problem can get worse and spread to other parts of the property or cause the situation to worsen very quickly. These type of repairs often involve using specialist contractors who have experience using these materials and are able to replicate, restore or fix the current damaged material without the need to completely replace.
A material change is a different material replacing the original material, or a different appearance to the original. Planning permission is often not required for a change of material or a true repair for properties that are not flats, not listed and not in a conservation area. Otherwise planning permission is required.
Practical examples include matching clay to clay, slate to slate for roofs, and timber framed windows with new glazing to match the appearance and character of the existing. Permitted Development is applicable when the like for like replacement is not restricted by conservation area, article 4 designation, listed building and conversion to flats.
Depending on the type of property and its location, small changes to the colour of the façade or material can trigger the need for planning permission.
Alterations to a roof which involve changing the roof shape, pitch, dormers, hip to gable or skylights usually require planning permission even if tiles are similar.
If the property is not situated in a conservation area, certain extensions and replacements can be carried out without permission from the council. A rear extension is often permitted development including a front porch, loft conversion with extension to the roof, outbuilding, garage conversion and more.

A distinct topic from conservation areas: listed buildings often require Listed Building Consent in addition to or instead of planning permission. The requirement for Listed Building Consent is for all internal works and external works to a listed building. Planning permission is only required to the external works to a listed building.
Emergency repairs that are genuinely necessary to make a roof weather-tight can be carried out without permission, as waiting 8-12 weeks for a decision can be harmful to the fabric and historical significance of the building. However, it is strongly recommended to reach out to the council by email to explain the situation and to clarify that retrospective permission is to be submitted in due course. 4D Planning encourage all clients to seek the council’s written consent prior to carrying out any works.
The best way to find out if planning permission is needed is to contact 4D Planning and we will have a look at the situation and advise you how best to proceed. You can also consider a formal pre-application advice from the council.
The purpose and benefit of lawful development certificates (based on the PD rights) is to -provide certainty on the legal status of works and to protect against future enforcement.
There is an opportunity to apply for retrospective planning permission to regularise the situation. This will prevent enforcement action from proceeding and the council will have to wait until the application is decided.
