Replacing a roof is a significant investment for any homeowner, and understanding the costs involved is essential for budgeting and planning. The cost of replacing a roof in the UK depends on various factors, such as the size of the roof, the materials used, and labour charges. This article will provide a detailed breakdown of what influences the average cost to replace a roof and help you make informed decisions.
Factors Influencing the Cost to Replace a Roof
1. Type of Roof
The type of roof you have will play a significant role in determining how much it costs to replace a roof:
- Flat Roofs
- Pitched Roofs
- Hip Roofs
- Gable Roofs
2. Roof Size
Roofers calculate labour and materials based on square meters. A larger roof naturally demands more tiles, underlayment, timber, and labour hours. Estimating your roof’s total area accurately before requesting quotes provides a clearer idea of the cost and helps avoid unexpected price increases during the project.
3. Roofing Materials
Prices vary widely depending on the roofing material chosen:
- Basic concrete tiles: cost-effective and durable, typically priced from £18–£40/m².
- Slate tiles: premium natural material lasting 80–100 years, costing £160–£275/m².
- Clay tiles: aged aesthetic and durable, costing £29–£52/m².
- Metal roofing: modern and lightweight, priced between £9–£200/m², depending on the type.
- Flat roof materials (EPDM, felt): £70–£150/m².
4. Labour Rates & Location
Labour costs vary depending on the experience and expertise of the roofing contractor. Hiring professionals ensures quality work, but it may be more expensive.
5. Scaffolding & Access Needs
The cost of replacing your roof will increase if scaffolding is needed. Roofs that are harder to access or require complex scaffolding setups will also increase the expense.
6. Removal of Old Roof & Waste Disposal
Tearing off old tiles, disposing of debris, and hiring a skip can cost between £1,000 and £2,500, depending on the size of the roof. Disposal costs can increase if materials are heavy or contaminated. Planning to reuse materials or carefully sorting waste for recycling can reduce some of these charges.
7. Structural Repairs & Upgrades
Old or damaged roof frames may require strengthening or replacement at £2,500–£4,500. Updated insulation or ventilation (to comply with current building regulations) can further influence the price. Wooden timbers may require treatment or replacement to ensure long-term stability.
How Much Does It Cost To Replace A Roof In Uk?
Understanding the average costs of roof replacement can help you budget effectively and avoid unexpected expenses. Here’s a breakdown based on roof type:
Flat Roof Costs
If you’re replacing a flat roof, you can expect to pay between £2,800 and £7,500, depending on the size and materials used. The cost per square metre typically ranges from £45 to £150. Flat roofs are generally the most affordable to replace, making them a popular choice for additions, such as extensions or garages, or smaller homes.
Gable Roof Costs
Replacing a gable roof usually costs between £7,000 and £16,250, with an average cost per square metre falling between £110 and £260. Gable roofs are common in UK homes and are relatively straightforward to replace. However, added features like skylights or complex angles may raise the price.
Hip Roof Costs
Hip roofs tend to be more expensive due to their complex structure. The total cost of replacing a hip roof ranges from £9,250 to £18,000, while the cost per square metre can go from £145 to £285. Their extra stability and curb appeal make them a popular, yet premium, choice.

Removal of Existing Roof: Stripping the old roof, including skip hire, may cost between £1,000 and £2,500.
New Roof Frame: If structural work is needed, constructing a new roof frame can increase expenses by £2,500 to £4,500.

- Choose Affordable Materials: Opt for cost-effective materials like asphalt shingles if budget is a concern.
- Schedule Repairs Off-Season: Roofing work is often cheaper during less busy months, such as late autumn or winter.
- DIY Some Tasks: Remove old roofing materials to save on labour costs.
Conclusion
The cost of replacing a roof depends on several factors, including its size, materials, and labour. Investing in quality materials and experienced contractors ensures the durability and longevity of your new roof.
