Current market guide
Checkatrade’s 2026 planning guide gives an overall UK average of about £8,000 and a broad £4,000–£19,000 range. Its separate installation guide reports an average around £13,000. Those figures are market budgeting references, not BuildPair prices, and the spread shows why the roof specification matters.
What should be in the quote
• Roof area and whether measurements are plan area or slope area.
• Tile, slate or membrane specification and underlay.
• Scaffolding, skips and removal of the old covering.
• Allowance for rotten battens, decking or structural timber.
• Insulation, ventilation, flashings, gutters and making good.
Building Regulations check
GOV.UK lists replacement of roof coverings on pitched and flat roofs among alteration projects that can require Building Regulations approval. Confirm the position for the exact work before it starts.
