Average Cost of Roof Replacement in 2026 (Learn More)
Planning a new roof in the UK during 2026 means budgeting for materials, labour, scaffolding, waste removal, and possible insulation upgrades. This guide outlines typical price ranges per square metre and by roof type, key cost drivers that affect your quote, and a comparison of real systems from recognised providers to give you realistic expectations.
Understanding what a new roof could cost in 2026 helps you prioritise maintenance, forecast budgets, and avoid surprises when quotes arrive. Prices vary widely between materials like concrete tiles, clay tiles, slate, and flat roofing membranes, while property size, roof complexity, and access add further variation. The figures below reflect typical conditions for UK homes and should be used as a planning guide rather than a final quote.
Average Cost of Roof Replacement in 2026
For a typical three bedroom semi with a 70 to 90 square metre pitched roof, a full replacement with concrete interlocking tiles commonly ranges from about £7,000 to £14,000 including labour and materials but excluding scaffolding and VAT. Clay tile roofs often run £9,000 to £18,000, while natural slate may reach £12,000 to £22,000 due to higher material and labour requirements. Flat roofs on garages or extensions of around 20 to 30 square metres generally cost £1,200 to £2,000 for torch on felt, £1,800 to £3,000 for EPDM rubber, and £2,000 to £3,500 for GRP fibreglass.
What is the cost of replacing a roof?
Per square metre rates offer a practical way to compare options. In 2026, installed guide rates often fall around £80 to £120 per m² for concrete tiles, £100 to £150 per m² for clay tiles, and £120 to £180 per m² for natural slate. Flat roof systems trend near £50 to £80 per m² for bitumen felt, £70 to £110 per m² for EPDM single ply, and £80 to £120 per m² for GRP fibreglass. These ranges assume clear access, standard details, and straightforward geometry; complex roofs with hips, valleys, or dormers sit higher.
Roof replacement cost
Several factors can shift quotes up or down. Access and working height influence scaffolding, which for a two storey house may add £900 to £2,500 depending on elevations and duration. Waste disposal can add £250 to £600. Timber repairs to battens, rafters, or decking might range from £500 to £3,000. Upgrading insulation to current Part L standards is common during re roofing and can add £1,000 to £3,000 depending on approach. Regional labour differences can be notable, with London and the South East often 10 to 20 percent higher than many other areas.
Real world pricing insights also reflect scheduling and scope. A straightforward pitched reroof typically takes three to five days with a two to four person crew, while small flat roofs can be completed in one to two days. Quotes may be presented as fixed price or measured rates; check what is included, such as underlay type, battens to BS standards, ventilation provisions, dry fix accessories, lead or compatible flashing alternatives, and warranties on both materials and workmanship. VAT at 20 percent usually applies for standard residential work.
To help frame typical 2026 pricing in the UK, the comparison below lists well known roof systems from recognised providers with indicative installed cost ranges. These figures assume residential scale projects delivered by approved installers and include labour and materials for the covering, but exclude scaffolding, major timber repairs, insulation upgrades, and VAT.

Prices, rates, or cost estimates mentioned in this article are based on the latest available information but may change over time. Independent research is advised before making financial decisions.
Beyond material choice, request itemised quotes so you can compare labour, materials, ancillaries, scaffolding, and waste. Ask for confirmation of roof ventilation strategy, valley and verge details, ridge system, and whether dry fix components are used. For flat roofs, clarify insulation type warm or cold roof build up, thicknesses to meet U value targets, and compatibility among primers, adhesives, and membranes.
Where possible, seek warranties that align material guarantees with installer workmanship cover. Typical manufacturer warranties vary from 10 to 25 years depending on the system and specification, and some require registration and periodic inspections. Confirm who registers the warranty and what maintenance obligations apply.
Planning considerations can also affect timing and cost. Most like for like replacements proceed under permitted development, but conservation areas, listed buildings, or major appearance changes sometimes require consents. Slate in heritage contexts may need specific products to satisfy planners, which influences cost and lead times.
Finally, remember that quotes from local services in your area will reflect access constraints, roof geometry, and specific detailing on your property. Provide measured roof areas, photographs, and notes on existing layers when requesting estimates to reduce contingency allowances and help contractors price consistently.
A clear understanding of ranges, inclusions, and system differences will help you evaluate what is the cost of replacing a roof in 2026 with confidence. Using the guide rates above as a benchmark, you can interpret quotes more effectively and make choices that balance durability, appearance, and total project value for your home.
