Do You Need Planning Permission or Building Regs for a New Roof?

Like-for-like roof repairs may not need planning permission, while alterations, conservation controls and substantial renovation can change the position. Planning and Building Regulations must be checked separately for the actual property and scope. This guide explains the practical checks a Bromley property owner should make before requesting or approving work.

Quick answer

Like-for-like roof repairs may not need planning permission, while alterations, conservation controls and substantial renovation can change the position. Planning and Building Regulations must be checked separately for the actual property and scope.

Check permission and Building Regulations separately

Planning permission, permitted development and Building Regulations are different questions. Conservation areas, listed buildings, Article 4 directions, changes to height or shape, roof windows and material changes can affect what is allowed.

• Check the property’s planning and conservation status with Bromley Council
• Describe visible material, profile, colour and roof-shape changes accurately
• Ask Building Control whether the proposed scope triggers an application
• Confirm structural, thermal and fire requirements for the full build-up
• Keep written decisions, approvals, specifications and completion records

Use the current Bromley planning guidance, Bromley conservation-area guidance and the Planning Portal roof guidance. Obtain project-specific advice before work starts.

The main decision this article should support

A useful roofing decision starts with the cause and extent of the defect, not a generic product claim. Inspection, photographs and a written scope help distinguish a targeted repair from maintenance or full renewal.

• Whether defects are isolated or repeated across several slopes
• Condition of underlay, deck or visible timbers where accessible
• Safe access, scaffolding and waste-removal needs
• What evidence supports the proposed repair?
• Is the work temporary or permanent?

What should be inspected?

• Where and when water or damage first appeared
• Covering, flashings, junctions and drainage around the affected area
• Whether defects are isolated or repeated across several slopes
• Condition of underlay, deck or visible timbers where accessible
• Safe access, scaffolding and waste-removal needs
• Materials, exclusions and assumptions in the quotation

Plan for conditions found in Bromley and nearby areas

Relevant exposure includes driving rain, wind around roof edges, leaf and urban debris in outlets, and temperature movement at metal or membrane details. Inspection and maintenance should respond to the actual property rather than generic weather claims.

• Windward details checked after storms
• Outlets monitored through wet periods
• Debris traps included in maintenance
• Movement allowed for at rigid junctions

Assume sheeted roofs and rooflights are fragile

Old sheets, corroded material and rooflights can fail without warning. Do not test them by standing on them. A competent contractor should identify fragile areas and plan platforms, protection and access that avoid loading them. The HSE roof-work guidance explains the main requirements and hazards.

Questions to ask in the quotation

• What evidence supports the proposed repair?
• Is the work temporary or permanent?
• What is included and excluded from the price?
• What maintenance or future renewal should be budgeted?

Frequently asked questions

Does every roofing job require scaffolding?

No single access method fits every property. Height, duration, roof geometry, public areas and the task determine what safe access and edge protection are required.

Will a roofing quote replace a building survey?

No. A roofing quotation addresses a proposed work scope. Structural advice, valuation, asbestos surveying and a full building survey are separate professional services.

Can a roofer diagnose this from photographs?

Photographs can help initial triage, but they rarely show concealed layers, the complete water path or substrate condition. A site inspection is normally needed before a firm permanent-repair scope.
