Choosing the right roofing material
Different materials suit different budgets, property types, and roof pitches. Here’s a guide to the most popular roofing options in the UK.
Concrete tiles
The UK’s most popular roofing material. Affordable, durable (40–50 years), and available in many colours and profiles. Suitable for most pitched roofs.
£40–£55/m² fittedClay tiles
Traditional and premium. Clay tiles last 60–100 years, are colour-fast, and look excellent on period properties. Heavier than concrete — check your roof structure.
£55–£75/m² fittedNatural slate
The premium choice. Welsh and Spanish slate can last 80–150 years. Ideal for older, traditional, or listed properties. Requires specialist installation.
£80–£120/m² fittedFelt / flat roof
Used for flat or low-pitch roofs on extensions, garages, and bungalows. Modern torch-on felt lasts 15–25 years. Most affordable option for flat roofs.
£30–£45/m² fittedMetal (zinc / lead)
Standing seam zinc and lead roofs are extremely durable (60–100 years) and low-maintenance. Popular on contemporary builds and heritage restorations.
£90–£140/m² fittedEPDM rubber
A modern flat-roof solution that’s lightweight, seamless, and highly waterproof. Lasts 25–50 years with minimal maintenance. Great value for extensions and garages.
£25–£40/m² fittedRoof replacement cost by property type

How to save money on your roof replacement
Follow these expert tips to get the best quality roofing work at a fair price and avoid common pitfalls.
Get 3 quotes minimum
Always get at least three written quotes from different roofers before committing. Prices for the same job can vary by 30–50% — but be wary of quotes that seem suspiciously low, as this can signal cheap materials or corner-cutting.
Check credentials
Use a roofer registered with the National Federation of Roofing Contractors (NFRC) or TrustMark. Ask to see proof of public liability insurance. Reputable roofers will never ask for full payment upfront.
Time it right
Roofers are busiest in autumn and early spring. Booking in summer or mid-winter (weather permitting) can sometimes get you a better deal. Avoid rushing — emergency or last-minute jobs cost significantly more.
Repair vs replace
If your roof is under 15 years old, spot repairs may be sufficient. A full replacement is usually worthwhile when more than 30–40% of tiles are damaged, when the felt underlayer is deteriorating, or when battens show rot.
