How to Tell a Dodgy Roofer (UK Homeowner’s Guide, 2026)
The 60-second answer: Five red flags identify a dodgy UK roofer: (1) door-to-door cold caller offering an unrequested quote, (2) demand for cash deposit upfront before any work, (3) no fixed-price written quote — just verbal estimate, (4) refuses to name the membrane manufacturer
SIX THINGS, EVERY JOB
What you get with Eco Roofers
What we typically see on Greater Manchester roofs
Greater Manchester roof-stock combines dense Victorian terrace (M14/M16/M21 — Rusholme, Whalley Range, Chorlton), inter-war semis through Didsbury and Withington, post-war estates through Wythenshawe and Salford, plus stone-slate cottage stock through the Oldham/Rochdale Pennine fringe.
Local weather notes. Wet-Atlantic weather means moss growth is markedly worse than the East Midlands — valley leaks and lead-flashing failure are more common.
Approved Document L 2022 sets the thermal performance baseline for new roofs (U ≤ 0.16 W/m²K pitched, ≤ 0.18 flat). On flat roofs, BS 6229:2018 sets the design and falls standard. Eco Roofers will guide you through any Building Control notification needed on your job.

Sean’s view (from inside the trade)
I’m Sean Brown, owner of Eco Roofers and Exteriors. I’ve been doing roofing across Notts and South Yorks for over a decade. The reason this page exists: every week I quote on a roof that’s been ruined by a dodgy roofer. Sometimes the homeowner paid £8,000 for what should’ve cost £2,000. Sometimes they got a £200 patch on a roof that needed strip-and-replace. Sometimes they paid a deposit and the roofer never came back.
I’d rather you read this page and call someone else than fall for any of the patterns below. Here’s the real list.
Five red flags — any one of these means walk away
1. Door-to-door cold caller offering “we noticed your roof from down the street”
The pattern: A van pulls up. Someone knocks. They’ve “just done a job round the corner” and they “noticed your roof needs work”. They have a special offer that ends today.
Why it’s a red flag: Reputable roofers don’t generate work this way in 2026. We get our work from referrals, online presence, and existing customers — not by pressure-selling to homeowners they’ve spotted from the road. The “job round the corner” line is almost universally a cold-caller script. The “ends today” pressure is always a manipulation.
What to do: Politely close the door. If you’re worried about your roof, get three written quotes from local roofers via your own research (Google, Checkatrade, TrustATrader, MyBuilder, Rated People).
2. Demand for a cash deposit upfront before any work starts
The pattern: “I need 30%/50% upfront for materials.” “I can’t start the job without a £2,000 deposit.” “Cash only — I’ll knock off the VAT.”
Why it’s a red flag: Reputable UK roofing businesses run trade accounts with merchants. We don’t need homeowner cash to buy materials. On any job under about £5,000 we work without a deposit; on larger jobs (£8,000+) some roofers take a small deposit (10-15%) to cover material lock-in. Anyone demanding 30%+ cash upfront is either cash-flow-stressed or planning to disappear.
What to do: Refuse the deposit. Offer to pay on stages — for a larger job, that might be 25% on first delivery of materials, 25% at completion of strip, 25% at completion of new roof, 25% on satisfactory sign-off. A reputable roofer will accept staged payment. A dodgy one won’t.
3. No fixed-price written quote — only verbal estimates
The pattern: “It’ll be around £4,000-7,000, give or take.” “I won’t know until we start.” “Let me see how it goes.”
Why it’s a red flag: A roofer who can’t fix-price a quote either lacks the experience to scope properly, or is leaving themselves room to bill open-ended. Either way, you’re carrying the risk.
What to do: Ask for a written fixed-price quote covering: materials with named manufacturers, labour, scaffolding, skip, waste removal, and any contingency cap (typically £300-£800 for hidden deck rot on a 3-bed roof). If they can’t provide that in writing, get another quote.
4. Refuses to name the membrane manufacturer or quote a U-value
The pattern: “We use trade rubber from the merchants.” “I’ll tell you on the day.” “Don’t worry about U-values, we know what we’re doing.”
Why it’s a red flag: Modern UK roof installations involve named-manufacturer materials with documented warranties. EPDM membrane comes from Firestone (Eco Roofers is a Firestone Elevate approved installer) (UK majors); tiles from Marley, Redland, Sandtoft, etc.; insulation from Celotex, Kingspan. A roofer who can’t name the manufacturer either doesn’t know what they’re using or doesn’t want you to check the warranty terms.
What to do: Demand the manufacturer name and the spec sheet in the written quote. Cross-check: does the manufacturer offer the warranty the roofer claims? Does the warranty require certified-installer status?
5. No public liability insurance certificate
The pattern: “We’re insured.” “I have a certificate, I’ll bring it next time.”
Why it’s a red flag: If a tile slips during work and breaks your conservatory, or scaffolding marks your driveway, or your neighbour gets injured by falling debris — your home insurance won’t cover it. The roofer’s Public Liability does. Without a current PL certificate, you bear all the third-party risk on your own roof job.
What to do: Ask for the certificate in writing before work starts. Minimum £2M cover for domestic roof work. Verify it’s current (not expired). For larger commercial jobs, £5M+ is standard.
Five things a reputable roofer will always do
The positive checklist — what to look for when you’re hiring:
1. Fixed-price written quote, with line items
Materials, labour, scaffolding, skip, contingency cap, VAT — all in writing, all itemised. Quote valid for at least 14 days.
2. Named manufacturer + manufacturer warranty
EPDM: Firestone (Eco Roofers is a Firestone Elevate approved installer). Tile: Marley / Redland / Sandtoft. Slate: Welsh Slate (Penrhyn) or named Spanish slate quarry. Insulation: Celotex / Kingspan / Recticel. Manufacturer warranty in writing on completion.
3. Current Public Liability insurance certificate
£2M minimum domestic. Provided as a PDF on request. Verify with the underwriter if uncertain.
4. Companies House registration (limited companies) or HMRC self-employed registration (sole traders)
Limited company: check the company number on Companies House — search free at find-and-update.company-information.service.gov.uk. Confirms the company exists, is active (not dissolved), and lets you see the directors. Sole trader: ask for HMRC UTR (Unique Taxpayer Reference) for VAT-registered traders, or trade-association membership for non-VAT-registered.
5. Building Control notification path on notifiable work
Warm-roof retrofits, full replacements over 50% of roof area, structural changes — all are notifiable under UK Building Regulations. A reputable roofer handles notification via a Competent Person Scheme (CPS) — common UK schemes: Trustmark, NICEIC (electrical), Gas Safe (heating), HETAS (solid fuel). Roofing-specific CPS includes Bonded Roofers UK and TrustMark Roofing. Ask which scheme they’re registered with.
How to verify before you sign
A 30-minute due-diligence walkthrough that’s worth doing on any job over £2,000:
| Check | Where | How long |
|---|---|---|
| Company exists + active | Companies House (free) | 2 min |
| Owner / director on Companies House register | Same | 1 min |
| Existing reviews | Google, Checkatrade, TrustATrader, MyBuilder, Rated People — search company name | 10 min |
| Public Liability certificate | Ask roofer in writing | 5 min |
| Manufacturer specs in quote | Ask for spec sheet | 5 min |
| Address verification | Companies House registered office or site visit by the owner | 5 min |
| Reference customers | Ask for 2 recent customers willing to talk on the phone | 5-10 min outside the check window |
If a roofer refuses any of these checks, walk away. The work isn’t worth the risk.
What to do if you’ve already been ripped off
If you’ve paid a deposit and the roofer hasn’t returned, or the work is visibly substandard:
1. Document everything — photos of the work, copies of quotes and receipts, dates of contact attempts
2. Trading Standards — file a complaint via your local council or the Citizens Advice Bureau on 0808 223 1133
3. Action Fraud (if there’s evidence of fraud — taking money with intent to disappear) — 0300 123 2040 or actionfraud.police.uk
4. Small Claims Court — for sums up to £10,000, you can sue the roofer directly via the Money Claim Online service (£0–£455 court fees on a £2,000–£10,000 claim)
5. Trade-association complaints process — if the roofer claimed membership, escalate via the association
6. Bank chargeback — if you paid by debit or credit card, your bank may reverse the transaction within 120 days under Section 75 of the Consumer Credit Act

FAQ
How can you tell a dodgy roofer?
Five red flags: (1) door-to-door cold caller, (2) demand for cash deposit upfront, (3) no fixed-price written quote, (4) refuses to name manufacturer or quote a U-value, (5) no public liability insurance certificate.
How much should a roofer charge per hour?
UK roofers in 2026 typically charge £200-£300 per day (not per hour) for domestic work plus materials. For specific jobs (replacement, retrofit) pricing is usually quoted as a fixed price for the whole job. Day rate matters mostly for one-off repair callouts.
What happens if a roofer is unregistered?
Sole traders aren’t legally required to register a company at Companies House — many legitimate small roofers are sole traders without a Ltd. What matters is: (a) public liability insurance, (b) verifiable references, (c) HMRC tax registration if VAT-registered, (d) trade-association membership where claimed. Unregistered AND uninsured AND no references = walk away.
Should I always get three quotes?
For any job over £2,000, yes. Three quotes lets you spot outliers (the £8,000 quote for a £4,000 job, or the £2,000 quote for a £4,000 job — both red flags). Pick the middle quote from the roofer who answers your due-diligence questions clearest, not the cheapest.
What if a quote is way cheaper than the others?
Either the roofer has missed something, is operating below cost (planning to upcharge later), is using sub-spec materials, is uninsured, or is intending to disappear with a deposit. Cheapest is rarely the right answer for jobs over £2,000.
