Many factors influence the price of a roof replacement. This includes roof size, material and labour costs, along with regional and company price differences. 

Due to the many variables involved, roof replacements can range wildly from £4,000 to £19,000 depending on your individual case. You should note that the higher end of this budget applies to larger and more complex projects. 

The following article from the team here at WeatherTIGHT Systems will give guidance on everything that can influence the final amount. 

How much does a roof replacement cost? 

You might be wondering how much does a new roof cost in the UK? According to Checkatrade, the average cost to replace a roof in 2025 will be around £7000 though this can vary hugely between £4,000 – £19,000 depending on multiple factors. These estimations are based on UK roofs but there will be regional price differences which we will also explore below. 

What affects the cost of a new roof? 

The cost of re-roofing a house or premises depends on various elements, including: 

• Roof size and type: Larger roofs require more material and more labour hours to complete, increasing the overall price. Likewise, the roof style will also influence cost. More complex styles that include skylights, dormers or a pitched design will often cost more than simple flat roofs. 

• Materials: Different roof materials arrive with their own price tags. Premium materials that are expected to last longer will be more expensive than cheaper materials with a lower expected lifespan. Slate is considered the priciest roof, while felt and single ply are more affordable yet durable. 

• Labour costs: The cost of labour will depend on the size and complexity of the project, along with the company you choose. You will often find that the cheapest company is not always the best, so always choose experienced experts who have guarantees and accreditations to their name. 

• Access and scaffolding: If the project requires additional access needs or scaffolding, this will need to be factored into the price. Consult with your chosen company for prices. 

• Regional price differences: Different areas of the UK have different prices for services, so you will need to research average costs in your area for a more accurate view. 

• Building regulations approval: Many roof replacements will need Building Regulations approval which arrives with a small fee. Check if you require this and factor it into the final amount.
