A replacement roof can feel like an improvement that will make a house easier to sell. But a new roof with no building regulations certificate can prompt questions when the buyer’s conveyancer reviews the paperwork.
Was approval required? Was the work inspected? Is a certificate missing, or was one never issued? And what happens if the question arises after contracts have already been exchanged?
The immediate task is to establish the history of the roofing work and the evidence available. Buying an indemnity policy or applying for retrospective approval should follow that investigation and advice about the particular transaction.
A replacement roof becomes a late conveyancing enquiry
One homeowner’s online account illustrates the problem. They described having a new roof installed approximately three years earlier by a builder they could no longer trace.
When selling, they were asked to produce a building regulations certificate. They did not have one and believed approval had not been requested.
There was an additional complication: the homeowner said contracts had already been exchanged as part of a new-build part-exchange arrangement. The developer had also arranged an onward sale to another buyer.
The account does not establish whether approval was legally required, whether any building control record existed or how the transactions concluded. It shows how uncertainty about earlier building work can become an urgent conveyancing question.
For the wider conveyancing position, see our guide to selling or buying a property with a missing building regulations certificate, including recovering documents, indemnity insurance and retrospective approval.
Missing paperwork for building work?
Our main guide explains the difference between a lost certificate, unfinished approval and work carried out without the required process. It also considers insurance, retrospective approval and mortgage lender requirements.
Does a replacement roof need building regulations approval?
The description “new roof” is not enough to answer that question. It might mean limited repairs, replacement of the covering, structural alterations or a more extensive rebuilding project.
For an ordinary house in England, the extent of the work matters. Structural alterations, changes to the covering’s weight or fire performance, and the amount of roof affected can all be relevant. Insulation requirements may also need consideration.
The Planning Portal’s guidance on work to an existing roof explains these distinctions. The applicable requirements also depend on when the work was carried out.
Planning permission is a separate question. An explanation that planning permission was unnecessary does not establish that building regulations approval was unnecessary.
First establish what certificate is missing
Not holding a certificate does not prove that the roof was never approved. Equally, an invoice or a contractor’s assurance does not establish that the completed work received the necessary certification.
Gather the records already available, including:
- The quotation, specification and invoice for the roof.
- The approximate start and completion dates.
- Photographs showing the work undertaken.
- Any drawings, calculations or inspection correspondence.
- Building control references or certification documents.
- Any contractor guarantee or insurance-backed warranty.
A guarantee and a building regulations certificate serve different purposes. Keep both if available, but do not treat one as a substitute for the other.
Ask your conveyancer to identify the exact document requested and assess the appropriate way to investigate the records. Before contacting building control about potentially unapproved work, discuss the implications for any existing or proposed indemnity insurance.
What if the builder cannot be traced?
The builder’s absence may make it harder to obtain the original specification, correspondence or guarantee. It does not establish whether a building control record exists.
Nor does it automatically make insurance the correct solution. The decision still depends on what work was done, whether approval was required, the property’s condition and what the buyer and any mortgage lender will accept.
If there are concerns about leaks, movement or the roof structure, ask whether an appropriately qualified surveyor or structural engineer should investigate. A legal paperwork solution does not establish that the roof is sound.
Can indemnity insurance resolve the missing roof certificate?
Building regulations indemnity insurance may help where the buyer and lender accept cover for the identified risk. Availability and suitability depend on the particular facts and policy wording.
The important distinction is between financial protection against specified enforcement consequences and evidence that the roof complies with building regulations.
An indemnity policy does not inspect or approve the roof. It should not be treated as a general warranty against leaks or defective construction, and it does not prevent a local authority from taking action.
Policy conditions also matter. For example, the GCS building regulations specimen policy contains restrictions concerning communication with the local authority and applications for regularisation.
Ask your conveyancer to explain the proposed cover, exclusions, insured parties and lender requirements. If anyone has already contacted the authority, disclose what happened so the insurer can assess it accurately.
Could retrospective approval be obtained?
Regularisation is a local authority process for seeking retrospective approval of eligible work carried out without consent. It is an assessment process, rather than simply the purchase of a replacement certificate.
GOV.UK’s regularisation guidance explains that alterations may be required before a certificate can be issued.
For a roof, ask what investigation, access and supporting information would be needed. Establish the likely implications for cost and the sale timetable before deciding how to proceed.
If a building control application already exists but was never completed, the appropriate question may instead be how to finish that process.
What changes if contracts have already been exchanged?
A request raised after exchange needs prompt advice from the conveyancer handling the transaction. The answer depends on the contract, earlier disclosures, any agreed arrangements and the exact wording of the new enquiry.
In a part-exchange transaction, distinguish between your agreement with the developer and the developer’s onward sale. Establish who is asking for the certificate, which contract is affected and what is actually required of you.
Ask your conveyancer to clarify:
- What was disclosed about the roof before exchange.
- Whether the missing document was previously discussed.
- What obligation, if any, remains outstanding under your contract.
- Whether a proposed solution needs approval from another party or lender.
- Whether the enquiry affects the agreed completion arrangements.
Do not assume that a request for paperwork gives either party an automatic right to withdraw or changes the completion date.
What if the roof work happened before you bought?
That is a different question from work you commissioned during your ownership. If the replacement roof predates your purchase, the original conveyancing records may help establish what the seller disclosed, what evidence was obtained and what you were told.
Check your report on title, search results, replies to enquiries and any indemnity policy. A missing certificate does not, by itself, establish that your conveyancer was at fault.
Was the missing approval an issue when you bought?
If the work predates your ownership and is now causing difficulty selling or remortgaging, When I Bought explains which purchase records and historical lender requirements may help clarify what happened.
