A new roof is one of the biggest investments for any homeowner in the UK. Whether your old roof is leaking, damaged, or simply reaching the end of its lifespan, knowing the real cost helps you plan your budget with confidence. Roof prices vary because every home is different. Factors like roof size, materials, labour, access, and location all play a big role in the final cost.
This complete 2025 cost guide explains everything in simple words. You will learn how much a new roof costs in the UK, what affects the price, and what you can expect during the roof replacement process.
How Much Does a New Roof Cost in the UK?
In the UK, the average cost of a new roof ranges from £4,500 to £15,000, depending on materials and size. Smaller roofs with simple shapes are cheaper, while larger, complex roofs cost more.
Here is a quick overview:
-
Terraced house: £4,500 – £7,500
-
Semi-detached house: £6,000 – £10,000
-
Detached house: £7,500 – £15,000
-
Bungalow: £5,000 – £12,000
If you choose premium materials like natural slate or clay tiles, the price goes even higher. Asphalt and concrete tiles are usually the most budget-friendly options.
What Affects the Cost of a New Roof?
Every roof is different, so the final cost depends on several factors. Understanding these points helps you make better decisions.
1. Roof Size
The bigger the roof, the higher the cost. Roofers calculate by square metres. A larger surface area means more materials and more labour time.
2. Roof Material
Different roofing materials have different prices, lifespans, and appearances.
-
Asphalt shingles: Cheapest option
-
Concrete tiles: Affordable and long-lasting
-
Clay tiles: Stylish but more expensive
-
Slate (natural or synthetic): Premium, durable, and costly
-
Metal roofing: Modern and durable, medium to high cost
Choosing the right material depends on your budget and the look you want.
3. Labour Costs
Labour prices vary across the UK. Areas like London and the South East are more expensive. Skilled installers also charge more, but they offer high-quality workmanship.
4. Roof Access
If your roof is difficult to reach, requires scaffolding, or is very steep, the cost increases. Safety is a big part of roofing work.
5. Roof Shape and Complexity
Simple, straight roofs cost less. Roofs with valleys, hips, dormers, or multiple angles require more work and therefore cost more.
6. Removing the Old Roof
Stripping old tiles or slates adds extra labour. Old materials must be removed, disposed of, and replaced with new felt, battens, and tiles.
7. Underlay and Timber Condition
If the underlying timber structure is damaged by rot or moisture, repairs become necessary. This increases cost but ensures long-term safety.

What Happens During a Roof Replacement?
A new roof installation involves several steps. Knowing the process makes everything clearer.

Any rotting or damaged wood is replaced. This step ensures the new roof is safe and strong.

6. Laying New Roofing Material
New tiles, slate, or shingles are installed neatly and securely.

Ridge tiles, hip tiles, and edges are sealed properly to prevent leaks.
