Compare Roofers: How to Choose One in 2026 UK
To pick the right roofer in 2026 UK, score every quote on six things: NFRC or CompetentRoofer membership, RoofCERT individual accreditation, £5m+ public liability, a 10–20 year written workmanship guarantee, an itemised quote (line-by-line, not 'all in'), and 3+ recent photographed jobs within 10 miles. Roofing is the trade with the highest complaint rate at TrustMark — a structured comparison rubric protects you.
How to compare roofers — the 2026 checklist
- 1. Body membership: NFRC (National Federation of Roofing Contractors), CompetentRoofer or TrustMark
- 2. Individual accreditation: RoofCERT (assessor must hold it, not just the firm)
- 3. Insurance: £5m+ public liability, employers' liability if any staff, contract works cover
- 4. Guarantee: 10–20 yr workmanship written, plus separate manufacturer's product warranty (e.g. GAF, IKO, Sika 25–40 yr)
- 5. Quote quality: itemised (labour, materials by m², scaffold, skip, VAT) — not 'all in' lump sums
- 6. Local proof: 3+ recent (last 12 months) jobs within 10 miles, photos and willing references
Red flag rule: any roofer who knocks door-to-door, demands cash, can 'start tomorrow', has no fixed address or refuses to provide their NFRC/CompetentRoofer ID for verification — walk away.

Roofer red flags to avoid in 2026 UK
- Door-to-door cold call: 'we noticed your tiles look loose...' — the single biggest source of TSI complaints in roofing
- Cash-only / no VAT receipt: implies no insurance and no comeback
- 'Start tomorrow' availability: any competent roofer in 2026 has at least 4–6 weeks of work booked
- No fixed business address / mobile only: can't be traced for warranty work
- Refuses written itemised quote: a quality firm provides labour, materials by m², scaffold, skip and VAT separately
- Asks for >25% deposit: NFRC/TrustMark norm is 10–20% materials deposit, balance on completion
- Pressure-sells 'today only' discount: any reputable price is valid 30+ days
Frequently asked questions
Get three written itemised quotes for an identical scope of work. Compare line by line: labour days, material grade and quantity by m², scaffold cost, skip, VAT. Beware quotes that are >30% under the median — they usually mean missing scope or stripped-down material spec.
NFRC is the trade body — vets the firm and offers an insurance-backed guarantee. CompetentRoofer is a government-approved Competent Person Scheme that lets a roofer self-certify Building Regs Part L compliance, saving you the LABC inspection fee. Top roofers hold both.
Yes. RoofCERT accredits the individual rather than the firm — so it's the only proof you have that the actual roofer climbing your scaffold has been competence-tested. Always ask which named operatives on site hold it.
NFRC and TrustMark norms are 10–20% as a materials deposit, with the balance staged or paid on completion. Anything above 25% before work starts is a red flag, regardless of size of job.
Workmanship guarantees from NFRC roofers are typically 10–20 years; manufacturer's product warranties (e.g. GAF, IKO, Sika single-ply, Marley tiles) run 25–40 years. NFRC's Insurance Backed Guarantee (IBG) protects the workmanship guarantee if the firm ceases trading.
Use them as one signal, not the only one. Check the volume (50+ reviews, not 8), distribution (some 3 and 4-star is healthier than all 5-star), recency (within last 12 months) and whether the firm responds to negatives. Always pair with NFRC/CompetentRoofer registration check.
