Cost is usually the deciding factor between tile and slate. But the headline 'per m²' figure hides the real comparison: lifetime value, repair costs over 50 years, and what happens to your house value at sale. Here's the full picture.
Is slate really cheaper over the long term?
Often yes. A £15,000 slate roof lasting 100 years works out at £150/year. A £10,000 concrete tile roof lasting 50 years works out at £200/year — plus the disruption of replacing it.
What's the cheapest pitched roof option?
Concrete interlocking tiles — typically £95–£110/m² supplied and fitted. Good for budget-driven projects on modern properties.
Does slate cost more to repair?
Per slate, yes — but you replace far fewer over the roof's life. Tiles need more frequent point repairs as they age.
