What affects the cost?

• Roof type (concrete tile, clay, slate, flat) — slate is roughly 2× concrete
• Total m² of roof area — measured along the slope, not the footprint
• Pitch — steep roofs need more scaffolding and slow the job
• Whether felt and battens are being renewed (you should renew them with the tiles)
• Ridge and verge details — dry-fix ridges cost more but last longer
• Chimney work or chimney removal
• Scaffolding access — detached homes are quicker; terraced rows need more permits

Cost breakdown

Cost by UK region

Regional pricing varies by up to 50 %, mostly driven by labour rates. These multipliers apply to the base UK cost:

Planning permission?

Not usually required for like-for-like; needed if changing materials in a conservation area

How long does it take?

5–12 days typical, plus design and approvals time beforehand.

DIY vs Professional

Difficulty: Pro required. UK building regulations and Part P/Gas Safe rules mean most of this work must be done by registered professionals. Even where DIY is permitted, paying a pro is usually faster and more reliable.

How to save money

• Replace felt and battens at the same time — doing it later means another scaffold bill
• Switch to dry-fix ridges if you're re-roofing — no future mortar repointing
• Consider re-roofing as the trigger for adding loft insulation top-up (PIR boards)
• Get the chimney inspected/removed before the scaffold comes down
• Mid-summer is the worst time to book — try late-spring or early-autumn for better pricing

Frequently asked questions

How long does a new roof last?

Concrete tile: 40–60 years. Clay tile: 60–100 years. Natural slate: 100+ years. Flat roof (EPDM/GRP): 25–40 years. Felt and battens typically need redoing every 50 years even if tiles are reusable.

Can I get a grant for a new roof?

There’s no national UK roof grant in 2026 for owner-occupiers, but ECO4 may fund insulation upgrades if you re-roof a property occupied by an eligible benefits claimant. Always check Simple Energy Advice for current schemes.

Do I need scaffolding for a roof replacement?

Yes — for anything beyond a small repair. Working from ladders on a pitched roof is illegal for paid trades under the Work at Height Regulations 2005.

How do I know my roof needs replacing?

Signs include slipped tiles (more than 1–2 per slope), sagging ridge line, multiple leak patches in the loft, moss build-up causing channels in the felt, and felt visible through gaps. A roofer survey costs £80–£150.
