How Much Should a new roof cost?

If your roof is leaking, worn out, or past its lifespan, you’re probably wondering the big question:

“How much should a new roof cost?”

In the UK, a new roof typically costs between £1,000 and £10,000, depending on the size, materials, and condition of the property.

But for most standard homes, especially semis and detached properties, the realistic range is:

👉 £7,500 – £12,000 for a full new tile roof

👉 £10,000 – £20,000 for a new slate roof

👉 £70 per m² for EPDM flat roofs

👉 Higher for GRP fibreglass roofs

This guide breaks down the real costs so you know exactly what to expect — and what affects the price.

Average New Roof Costs in the UK (2025)

Here’s the current national picture:

🔹 New Tile Roof (most common choice)

£7,500 – £12,000

Concrete tiles typically last around 40 years and come in multiple styles.

🔹 New Slate Roof

£10,000 – £20,000

More expensive but extremely long-lasting — 60–80 years.

🔹 New Flat Roof (EPDM Rubber)

Around £70 per m²

One-piece membrane, flexible, long-lasting, great value.

🔹 New Flat Roof (GRP Fibreglass)

Higher than EPDM

Premium option with a sleek, seamless finish and 25+ year lifespan.

🔹 Small Roof Sections / Porches / Extensions

£1,000 – £4,000

Depending on size, access, and materials.

What Affects the Cost of a New Roof?

Not all roofs are built the same — here are the biggest factors that change the final price:

1. Roof Size

Larger roofs cost more due to extra materials and labour.

2. Material Choice

•Concrete tiles → affordable

•Clay tiles → mid-range

•Slate → premium

•EPDM → cost-effective for flat roofs

•GRP → high-end, modern finish

3. Roof Condition

If felt, battens, or timbers need replacing, the price increases.

4. Access & Scaffolding

Every full roof replacement requires scaffolding.

Hard-to-reach homes cost more.

5. Features of the Roof

Extras add to the cost, including:

•Dry ridge

•Dry verge

•Leadwork

•Chimney repairs

•Valleys & hips

•Additional ventilation

6. Your Location

Labour costs vary across the UK, though the estimates above reflect national averages.

How Long Does a New Roof Last?

Depending on material:

•Concrete tiles: ~40 years

•Slate: 60–80 years

•EPDM (flat roof): 20–25 years

•GRP (fibreglass): 25+ years

Cheaper materials usually mean shorter lifespan — and more future repairs.

Should I Repair or Replace My Roof Instead?

Some leaks can be fixed with simple repairs.

But you likely need a replacement if:

• The roof is over 30–40 years old

• Leaks keep returning

• Tiles keep slipping

• Felt is perished

• Moss is lifting tiles

• Your roof structure is sagging

• You see daylight in the loft

If multiple issues are present, replacing the roof is usually more cost-effective in the long run.

What’s the Most Realistic Price for a New Roof?

Most UK homeowners should expect:

⭐ £7,500 – £12,000 for a full new roof

(using concrete tiles)

For slate, expect higher:

⭐ £10,000 – £20,000

For flat roofs:

⭐ £70 per m² for EPDM

⭐ Higher for GRP

These are the safest, most accurate ranges for 2025.
