Building Warrants and Planning for a New Roof

A building warrant is approval under the Scottish building standards system for work that requires it. Building standards concern matters such as the structure, weather resistance and energy performance. Planning considers development and its effects, including changes to a building's appearance. Approval through one system does not automatically give approval through the other, even when both enquiries concern the same roof.

This is general guidance, not a legal assessment of your property. Your council's building standards team can confirm the warrant position for the actual proposal, while the planning team can explain planning requirements. Describe what will be removed, what will replace it and whether the supporting roof structure changes. A broad request about a new roof can hide details that determine the answer.

A straightforward repair using similar materials may not require a warrant or planning permission, but that does not make every re-roof exempt. The scale of removal, changes beneath the covering and the building's status matter. A proposal described as like-for-like might still involve new insulation, altered loading or rebuilding part of the roof. Check rather than assuming that retaining the colour settles it.

Tell the council whether you mean replacing isolated damaged materials or stripping and renewing the covering across the roof. Include the existing and proposed materials and any changes in thickness, roof shape or detailing. A flat roof proposal needs the same care: replacing its exposed surface is a different description from changing its deck, fall or supporting structure. Ask for confirmation against the defined work before agreeing a start.

Structural alterations, changes to supporting timber and a heavier covering raise questions about the roof's ability to carry the load. Adding a dormer changes more than the surface finish and needs a separate permissions discussion. Do not assume that a roofing quote alone establishes structural suitability or authorises the change. Where drawings or specialist advice are needed, clarify who will provide them.

Insulation upgrades and changes to ventilation also belong in the description of the proposed work. They can affect building standards requirements even where the outside appearance stays similar. Tell building standards what is changing and ask which requirements apply; an exemption from obtaining a warrant does not mean relevant standards can be ignored. Our slate versus tile guide explains material considerations to raise before choosing a replacement covering.

Changes to roof shape, materials or prominent details can affect the planning position. Permitted development rights may apply to some work, but their scope and restrictions need checking for the property. A conservation area or a listed building brings additional considerations. Do not treat a neighbour's approval or a nearby roof as evidence that the same work is authorised at your address.

Listed building consent is separate from planning permission and a building warrant. Work affecting a listed building's character may need consent even when it looks like maintenance to the owner. Tell the planning team about the building's status and describe the proposed materials and details. If you are unsure whether protection applies, establish that first rather than relying on the age or appearance of the house.

Have photographs, the address and a clear description ready. Ask building standards whether a warrant is required, what supporting information they need and what completion process applies. Ask planning separately about permission, permitted development and any listed building consent. Roof windows and dormers should be identified explicitly rather than included under a general heading of roof improvements.

Keep the council's response with your project information. If the design changes after that discussion, check whether the advice or approval still covers it. Ownership, shared parts and access arrangements can also need resolving, but they are not substitutes for either council process. Avoid starting work while an unanswered permissions question could change the proposed scope or require additional information.

When discussing new roofs with Rowan Roofing, say what permissions advice you have already received and what remains uncertain. Ask the written quote to distinguish the covering work from any proposed structural, insulation or roof-window changes. A quotation describes work; it is not council approval and should not be read as confirming that a warrant is unnecessary.

For a strip and renewal project, our roof replacements page explains the service. Before agreeing work, clarify who is responsible for any application, drawings and required checks. Rowan Roofing provides homeowners with written quotes and honest advice; contact us with the roof details so the discussion can reflect the proposal rather than an assumed exemption.
