Roof Replacement Cost by Size or Type

Here’s a general cost estimate based on the size and type of the roof: 

Small Terraced House roofs are usually easier and faster to work on due to their compact size and simpler access, with replacement costs typically ranging from £4,000 to £8,000.

Semi-detached houses have roofs that cover a larger area and may involve more complexity, with replacement costs typically ranging from £6,000 to £12,000.

Detached houses typically require more scaffolding, Roofing materials, and labour due to their larger size and all-around accessibility needs, with replacement costs typically ranging from £10,000 to £20,000+.

Roof Replacement Cost by Shape

Different roof designs come with different challenges and costs:

Roof Type / Shape	Estimated Cost per m²	Notes
Flat Roof	£60 – £120	This is simple and easy to install.
Pitched Roof	£100 – £180	Its steeper angles require more skill and time for installation.
Gable or Hip Roof	£120 – £200	Its angled designs add to material and labour costs.
Complex Roof (Dormers, Valleys)	£150 – £250	Their more angles, joints, and flashing increase both complexity and the expense.

Labour and Installation Costs

Labour is the biggest part of your roofing bill. In most cases, labour accounts for 40%–60% of the total cost. Labour rates in the UK range from £150 to £250 per day per worker, depending on experience and location. For an average roof, installation can take 2 to 5 days.

Complex roofs or bad weather can extend this timeline and increase costs. Always ask if the labour is included in your quote and whether it covers things like clean-up and removal of old materials.

Factors that Affect the Cost of Roof Replacement 

The roofing cost can change based on several factors beyond size and material. Here are some extra costs you might need to account for:

Scaffolding

Most roofing jobs require scaffolding for safety and accessibility. It costs around £500 – £1,500, depending on your house height, roof shape, and complexity.

Weather Conditions

Bad weather can delay work and make it more difficult, especially during winter or rainy seasons. This could increase labour hours and project length.

Location

Costs in London and the South East are usually higher due to increased labour rates and living costs. Northern areas tend to be cheaper.

Emergency

Emergency roof replacements due to storm damage, major leaks, etc, cost more because of priority scheduling and possible weekend rates.

Money Saving Tips to Replace a Roof

The cost of replacing a roof is expensive, but there are ways to lower the price without compromising quality:

Always request at least three quotes from trusted roofing contractors. This helps you avoid overpaying and helps you get a reasonable rate.

If safe and legal, you might remove loose debris or help with light clean-up tasks to reduce labour time.

Try to book your project in spring or autumn, when roofers are less busy, which will help you negotiate a better price.

Emergency jobs typically come with premium charges. Schedule annual roof inspections to catch small issues early and plan roof replacement ahead of time.

Hiring Roofers in Enfield often means lower travel costs and quicker service. They’re also more familiar with local building rules and weather challenges.

Conclusion

Knowing the cost to replace a roof helps you plan better and avoid surprises. By comparing quotes, choosing the right materials, and taking advantage of grants or off-season deals, you can manage your budget more effectively. A strong, well-installed roof not only protects your home but also adds value and peace of mind for years to come.
