Replacing a roof is one of the largest and most expensive home maintenance tasks. The total cost can vary widely, so it’s important to understand what affects the price before you get quotes or start planning the work.
The total price depends on the type of roof you have, the materials you choose, and the size of your property. This guide breaks it down so you know what to expect and what factors affect the final cost.

Average cost to replace a roof in the UK
For a typical semi-detached house, a full roof replacement usually costs between £4,500 and £7,500. That includes materials, labour, scaffolding and waste removal.
Here’s a rough breakdown:
- Terraced house: £3,000–£5,000
- Semi-detached: £4,500–£7,500
- Detached house: £6,000–£12,000+
- Bungalow: £3,500–£6,500
- Flat roof (single garage size): £1,000–£2,500
These are ballpark figures. Always get a detailed quote from a roofer before agreeing to work.
What affects the price?
Several factors can increase or reduce your roof replacement costs.
Roof size and shape
Larger roofs obviously cost more. But complexity matters too. A simple pitched roof is easier and quicker to work on than a roof with multiple valleys, dormers or extensions.
Type of roofing material
Prices vary depending on the material you choose:
- Concrete tiles: most common and affordable
- Clay tiles: more expensive but longer-lasting
- Natural slate: traditional and durable but costly
- Synthetic slate: cheaper alternative with similar appearance
- Flat roof felt: cheapest option but shorter lifespan
- GRP/fibreglass: more expensive but modern and long-lasting
Accessibility and scaffolding
If your roof is difficult to access or needs extra scaffolding, expect higher labour and equipment costs. Terraced houses with limited side access may also need special arrangements for waste removal.
Condition of the roof structure
If your existing timbers or roof felt are rotten or damaged, they’ll need replacing too. This can add £500–£2,000 depending on the extent of the work.
Location
Labour costs vary across the UK. Roofing tends to cost more in London and the South East compared to Northern England, Wales or Scotland.
What’s included in the cost?
A proper roof replacement quote should include:
- Removal of old tiles or covering
- Repair or replacement of roof timbers (if needed)
- Supply and fitting of underlay and battens
- Installation of new tiles or materials
- Scaffolding and safety measures
- Waste removal and site clean-up
Always ask for a written quote that itemises each element.
Can you just repair part of the roof?
Sometimes. If the damage is localised and the rest of the roof is in good condition, a repair might be enough. But if your roof is over 25 years old or showing signs of widespread wear, replacement may be the more cost-effective long-term option.
If you’re not sure, get two or three opinions. Most roofers offer free inspections or quotes.
Should you get multiple quotes?
Absolutely. Roofing is a competitive trade, and prices can vary widely between companies. Get at least three quotes from trusted local roofers and compare them carefully.
Don’t just go with the cheapest. Make sure you’re comparing like for like.
How long does it take to replace a roof?
Most standard pitched roofs take 3–5 days to replace. Complex jobs or poor weather can delay things. Flat roofs are quicker and often done in 1–2 days.
Your roofer should give you a timescale when quoting.
Is a new roof worth the investment?
Yes. In most cases, a new roof will:
- Improve energy efficiency
- Prevent leaks and damp
- Boost your property value
- Improve kerb appeal if you plan to sell
Some homes may qualify for grants or schemes, especially if your roof affects energy performance. Check your local council website or GOV.UK for updates.
Final thoughts
A roof replacement is a major project. But with the right preparation, it doesn’t have to be overwhelming. Get clear quotes, ask the right questions, and take the time to compare options.
