FAQ
Frequently Asked Questions
A full concrete-tile re-roof on a typical 3-bed UK semi costs £6,500–£11,500 fully installed in 2026, including strip-off, new battens, breathable membrane, scaffolding and waste disposal. Clay tile adds 30–50% to the cost; natural slate adds 60–90%. London quotes typically run 25% above the UK average.
Replace (rather than repair) if any of the following are true: multiple leaks in different areas, visible sagging of the roof structure, 20%+ of tiles cracked or delaminated, underlay/felt has failed (daylight visible in the loft), the roof is at the end of its expected lifespan, or you're planning solar panels and want to combine the jobs. A local NFRC roofer can do a visual assessment from the loft and a ladder for free.
No — a like-for-like roof replacement is Permitted Development and doesn't need planning permission. You do need Building Regulations sign-off if you change the roof structure, upgrade insulation covering 25%+ of the roof area, or if the property is listed or in a conservation area. NFRC-registered roofers self-certify under the Competent Person Scheme. See our roof planning rules guide.
A typical 3-bed semi takes 5–7 days for concrete tile, 6–9 days for clay, and 7–10 days for natural slate. Detached houses run 8–12 days. Scaffolding is usually up for 2–3 weeks total. Bad weather can extend this — reputable roofers will tarp the roof overnight and won't strip more than they can felt back the same day.
Expected lifespans for UK roofs: concrete interlocking tiles 40–60 years, clay tiles 60–80 years, natural slate 75–150 years, EPDM rubber flat roof 30–50 years, GRP fibreglass flat roof 20–30 years, traditional felt flat roof 10–20 years. Ridge mortar and lead flashings may need attention at 20–30 years even if the tiles are still sound.
Scaffolding for a typical 3-bed semi costs £900–£1,800 for 2–3 weeks' hire in 2026 — around 8–12% of the total budget. Full detached houses or jobs needing multiple lifts (chimney stacks, valleys on two elevations) run £1,500–£3,500. Always check scaffolding is itemised separately so you can verify what's included (erection, weekly inspection, hire and removal).
If your roof is within 10 years of end-of-life, replace it first — it's more expensive to remove and refit solar panels than to install them on a brand-new roof. If your roof has 15+ years of life left, solar can go on the existing roof. Combining the two jobs saves £600–£1,200 on scaffolding and gives you a 20+ year runway on the new roof. See our solar panels cost guide.
The biggest drivers are tile choice (budget concrete vs premium clay or slate), membrane grade (basic vs high-performance breathable), BS5534 batten compliance, length of workmanship warranty, NFRC registration with insurance-backed guarantees, and whether scaffolding, waste disposal and flashings are fully itemised. Rock-bottom quotes typically cut corners on two or three of these — always get 3 quotes and an itemised breakdown.
