Re-roofing in Scotland: when you need a building warrant

Does a commercial re-roof in Scotland need a building warrant?
Sometimes, and the answer turns on one schedule. The Building (Scotland) Act 2003 requires a warrant for work for the construction or demolition of a building, and “construct” includes alter, erect and extend. Doing that work without a warrant is an offence. The handbook says those who may be guilty include the owners, tenants or developers who order the work, the person doing it and the owner where different.
The Act lets the Regulations specify work that needs no warrant, and regulation 5 and Schedule 3 of the Building (Scotland) Regulations 2004 do that. For a roof, the useful question is whether the job fits a Schedule 3 entry, not whether re-roofing sounds like maintenance. For roofing across the country, see commercial flat roofing in Scotland.
Which Schedule 3 entries could cover a roof covering?
Four come closest. Types 2 and 17 apply on condition that the work meets the standards in full. Types 24 and 25 only require the work to be “to a standard no worse than at present”.
| Entry | What the schedule says | Condition | For a roof |
|---|---|---|---|
| Type 2 | Any work to or in a non-residential building to which the public does not have access, except alteration of the roof, external walls or structure, and storeys above 7.5 metres | Standards in full | Wide cover for such buildings, but not for altering the roof |
| Type 17 | Work associated with thermal insulating material to or within a wall, ceiling, roof or floor | Standards in full | Insulation work, with the energy standards still applying |
| Type 24 | Replacing a fitting or equipment, including a rainwater gutter or downpipe, with the same general type | No worse than at present | Like-for-like gutters and downpipes |
| Type 25 | Replacing, in whole or in part, by material of the same general type, flooring, lining, covering or rendering | No worse than at present | Nearest wording to re-covering, but it never says “roof” |
The Procedural Handbook describes types 24 to 26 as work “closer to repair and maintenance than new work”, allowed without first obtaining approval because it is likely to form part of a repair contract, provided the replacement materials are of the same general type as the existing.
That leaves a gap. No Schedule 3 entry says in terms that replacing a flat roof covering needs no warrant, so treating a like-for-like strip-and-recover as a type 25 “covering” is a reading of the wording, and the local authority verifier’s reading is the one that counts. The handbook says verifiers “may consider issuing a letter” confirming that, on the information they have, no warrant is needed, though owners are not meant to apply for a warrant just for reassurance.
When does a re-roof fall outside the exemptions?
- A different type of covering. The condition is “material of the same general type”. Felt to single-ply is the obvious test case, and the verifier judges how far the phrase stretches.
- Changes to the roof itself. Type 2 excludes alteration of the roof, so new openings or deck changes sit differently from changing a covering.
- A worse result. Part B work must not leave the building worse in relation to the standards, for fire as well as insulation.
- Public access. Type 2 is only available where the public does not have access.
- Other work in the project. Where other work needs a warrant, the Schedule 3 work “should also be included in the warrant application”.
Do the standards still apply when no warrant is needed?
Yes. Regulation 5 says Schedule 3 work “shall meet the standards required by regulations 8 to 12” without needing a warrant, and the handbook says it “must still comply with the building standards”. If exempt work does not meet them, “a building warrant should have been obtained” and an enforcement notice can be served. An exemption removes paperwork, not responsibility.
Which standards matter most when a flat roof is re-covered?
The April 2026 non-domestic handbook applies to a building warrant submitted on or after 6 April 2026 and to exempt work commenced from that date. It is published as a PDF, so the passages below come from the 2022 web edition, which gov.scot publishes as web pages. Check the same clauses in the April 2026 PDF before relying on them.
Fire. Standard 2.8 ties a roof covering’s vulnerability to the distance of the building from the boundary: low vulnerability within 6 metres, low or medium between 6 and 24 metres, and any material beyond 24 metres. In the middle band, common materials include “felts and certain plastic materials”. England works from a different classification, explained in the BROOF(t4) guide.
Energy. Section 6 says the energy standards apply to “work on existing buildings, such as extensions, alterations and fit-outs”, but Standard 6.2 does not apply to non-domestic buildings that will not be heated, other than for frost protection. Where an element of the insulation envelope is dismantled and rebuilt, clause 6.2.13 says “the opportunity should be taken to improve the level of thermal insulation”. That is guidance a verifier weighs, not England’s fixed percentage test.
How do verifiers, warrants and completion certificates work?
The verifiers are Scotland’s 32 local authorities. Applications and completion certificates can be submitted through the eBuildingStandards service. A warrant is valid for three years from the day it is granted, and an amendment is needed before work departs from the approved drawings or specification.
A completion certificate confirms the work was done in accordance with the warrant and the building regulations, and submitting one known to be false is an offence. For alterations, the bar on occupying a building without an accepted certificate does not apply, but the certificate must still be submitted before the warrant expires. The person responsible may appoint an agent, such as an architect, building surveyor or structural engineer. Site safety law runs alongside: the Work at Height Regulations 2005 apply in Scotland, and the CDM 2015 guide covers project duties.
How does this differ from England?
England starts elsewhere. GOV.UK lists replacing roof coverings on pitched and flat roofs among alterations that may need approval, and regulation 23 of the Building Regulations 2010 requires the whole thermal element to comply, so far as feasible, where more than 50% of its surface area is renovated. GOV.UK also names NAPIT and CompetentRoofer as the authorised schemes for replacing roof coverings. Scotland answers the same question through Schedule 3 and the verifier.

Common questions
Can the council confirm in writing that my re-roof needs no warrant?
The Procedural Handbook says verifiers may consider issuing a letter confirming that, on the information available to them, the work does not require a warrant. Owners are not meant to apply for a warrant just for reassurance, so ask the verifier for a letter instead.
What happens if a re-roof started without a warrant that was needed?
The handbook says an offence has been committed, but a late application can be made at any time before the works on site are complete, and a late completion certificate if they are. The standards applied are those at the date of application.
Which handbook edition applies to a roof started in 2026?
gov.scot says the April 2026 non-domestic handbook applies to a warrant submitted on or after 6 April 2026 and to exempt work that starts from that date. Earlier editions remain relevant to warrants submitted before then.
Does roofing trade body membership replace the warrant process?
No. The person responsible must make sure a qualified, experienced professional does the work, ideally registered with a trade or professional body. Separately, a verifier treats a certificate from an approved certifier of construction as conclusive of the facts it covers, after checking the certifier was registered when it was signed.
