Listed buildings and conservation areas
Concrete tiles have replaced what look like older slates in a conservation area. Has the survey checked whether that change needed planning permission?
No. The survey has not checked whether replacing those slates with concrete tiles needed planning permission. It has seen a concrete-tile roof where the covering looks newer than the older slate roofs around it, inside a conservation area. A conservation area is an area designation, and a change of roof material can be the sort of alteration that needs permission. The visit did not search the planning register, did not date the work, and does not decide applications. The tiles are a condition and materials note, not a permission check.

What is the fuller explanation?
Historic England explains area designations such as conservation areas separately from the listing of one building. In a conservation area the council's interest can include the appearance of the roof, so a swap from slate to a heavier concrete tile is not only a covering question. The survey can record the tile, the way it meets the ridge and eaves, and whether the roof structure looks disturbed. It cannot, from the pavement and the loft, see whether permission was required or granted.
Ask the solicitor for the planning history and any building-regulations papers for the roof covering. Tell them the report sees concrete tiles in place of what look like older slates, and that it has not checked permission. A heavier tile can also matter to the structure, which is a separate question for the surveyor's roof comments, not a substitute for the planning search. The survey has not authorised the change.
What should you ask your surveyor?
- Where did you see concrete tiles, and what made you think older slates had been there?
- Did you inspect the planning register for this roof, or only the covering itself?
- What have you left undecided about permission for the change of material?
What are the typical next steps?
- Read the concrete tiles as a materials note, not as a planning clearance.
- Ask the solicitor to obtain the planning history for the roof covering.
- Keep any structural comment about the tiles separate from the permission question.
Costs vary with the building and with who you instruct. Where this page does not cite a published figure, ask the surveyor, a relevant specialist, or your solicitor for a written quote. Do not treat a forum average as the price.
Also asked about this
If the tiles look neat, has permission been shown?
No. A neat concrete-tile roof shows workmanship you can see. It does not show a planning decision. The survey has not searched the register, and a tidy ridge is not evidence that the change of material was permitted. Neatness and consent are different records.
Does a conservation area block every later roof repair?
The survey has not said that. It has also not checked whether this particular change, from what look like older slates to concrete tiles, needed permission. A conservation area is not a finding that no repair can ever happen. It is a reason the solicitor should search the planning history rather than assuming the new covering was free to proceed.
