A roofer knocked on your door and said they noticed some loose tiles while working on a neighbour's house. Or you searched online, found someone with decent reviews, called them out, and now they're asking for a large cash deposit before they'll start. Or a trader turned up in an unmarked van, gave a verbal quote, and wants to begin the same afternoon.
Any one of these scenarios could still lead to perfectly good work. But they are also the entry points for some of the most costly rogue trader scams that Trading Standards and Citizens Advice deal with in the UK every year. Roofing is among the top three sectors for consumer complaints nationally — not because most roofers are dishonest, but because it is easy to hide bad work on a roof that most homeowners can't inspect themselves.
This guide is a plain-English checklist of the ten warning signs that come up repeatedly in Trading Standards investigations, insurance disputes, and consumer fraud cases — and what a legitimate roofer does instead. If you are already mid-job and worried, skip to the end for what to do.
The 10 red flags — in order of how often they appear
They knocked on your door uninvited
The doorstep cold call — the single most reliable indicator of a rogue trader
Legitimate roofing contractors in the UK do not need to cold-call houses. Their work comes from Google, referrals, and repeat customers. The business model of knocking on doors is built on finding homeowners who can be pressured into quick decisions before they have a chance to get other quotes or do any research.
The most common pitch: "I was working on a house nearby and noticed your roof looks like it needs attention." This is designed to sound plausible and neighbourly. In practice, the "attention" they noticed is either exaggerated, invented, or caused by themselves going up to "check" — which brings us to red flag number two.
Take their details if you like, tell them you will consider their quote alongside others, and close the door. Never let an uninvited trader on your roof. If they become persistent or aggressive, that is a police matter.
They want to "go up and check" before giving a quote
Allowing roof access to a stranger is how damage gets created, not diagnosed
One of the most widely documented rogue trader techniques is the "free inspection" that results in a conveniently urgent repair quote. The trader goes on the roof, deliberately loosens tiles, pulls away flashing, or photographs unrelated damage — then presents it as an emergency discovered during their check.
Homeowners rarely go on their own roofs. They have no baseline to compare against. Whatever the trader says is up there, they have little choice but to take at face value. This is exactly the vulnerability that is being exploited.
No written quote — only a verbal price
If it isn't in writing, it doesn't exist in law
Every legitimate roofing contractor in the UK will provide a written quote before starting work. This does not need to be an elaborate document — even a detailed email counts — but it must specify what work will be done, what materials will be used, what the total price is, and what is excluded.
A verbal quote protects nobody. Once work starts, the price can be revised upward at any point and there is nothing you can do about it without written evidence. "Scope creep" — discovering additional urgent problems once the job has started — is only actionable if the original scope was defined in writing.
"Can you send me a written quote that confirms the work you'll carry out, the materials you'll use, the total price, and your payment terms? I won't be signing anything or making any payment until I have that in writing."
Business name and address, description of all work to be carried out, materials specified (brand, type, quantity), total price including VAT, estimated start and completion dates, payment schedule, and a warranty statement.
They ask for a large cash deposit upfront
The most direct route to losing your money with no recourse
Asking for a deposit is entirely normal. Roofing materials cost real money and a contractor has legitimate reasons to want some payment before they order them. What is not normal is asking for more than 25–30% of the total job value before a single tile has been touched, demanding the full amount in cash before starting, or refusing to accept bank transfer.
Cash-only is the tell. It eliminates your paper trail, prevents any card-based chargeback or Section 75 claim, and makes recovery through the courts significantly harder. A roofer who insists on cash and nothing else is structuring the transaction to make disappearing easy.
- Deposit of 20–30% on confirmation
- Stage payment at material delivery
- Balance on satisfactory completion
- Bank transfer or card accepted
- 50%+ deposit demanded upfront
- Full payment before work begins
- Cash only, no exceptions
- No VAT receipt offered
No proof of public liability insurance
If they cause damage to your home or injure someone, you could be left to cover it
Public liability insurance covers the contractor's legal liability for damage to your property or injury to a third party caused by their work. Without it, if their ladder falls through your conservatory roof, if a tile lands on a pedestrian, or if water damage results from poor workmanship — you are unlikely to recover costs from a sole trader with no assets.
Any legitimate roofing contractor will carry public liability cover of at least £1 million, and most carry £2–5 million. They should be able to produce their certificate of insurance on request without hesitation. If they cannot, or if they say they are "in the process of renewing it," walk away.
"Can you email me a copy of your public liability insurance certificate before we proceed? I'd also like to see the policy expiry date." A legitimate contractor does this without a second thought.
Their reviews are thin, recent, or suspiciously generic
Review manipulation is commonplace — here is how to read through it
Most UK homeowners check Google or Checkatrade reviews before hiring anyone, and most cowboy traders know this. A burst of five-star reviews with no detail ("Great work, very professional," "Highly recommend, very happy") posted over a short window is a pattern associated with purchased or fake reviews. So is a profile with 40 glowing reviews and a creation date six months ago.
Genuine roofing reviews tend to be specific — they mention the job type, the location, something about the interaction, and often a name. They are spread over months and years. Negative reviews exist but are responded to professionally. Look at the reviewer profiles too: if every reviewer has written only one review and has no photo, the probability of manipulation is high.
Signs of genuine reviews
Specific job details mentioned. Reviews spread over 12+ months. Reviewers have full profiles with multiple reviews. Occasional 3–4 star reviews present. Responses from the business are personalised.
Signs of manipulated reviews
All reviews posted within 1–3 months. Generic language with no specific detail. All reviewers are single-review accounts. No reviews below 5 stars whatsoever. Business profile created recently despite claimed years of experience.
They cannot provide a verifiable business address
A mobile number and a van are not a business
When you hire a contractor, you need to know where to find them if something goes wrong. A roofer with a genuine, established business will have a physical address you can verify — either through Companies House (if they are a limited company), on their website, or on their quote. This does not have to be commercial premises; many legitimate sole traders operate from home. But the address must be real.
If the trader provides only a mobile number, a Gmail address, and a general area ("based in South Yorkshire"), you have no way of pursuing them through the courts, through Trading Standards, or through any professional body if the work fails. This is not an accident — it is the point.
Search their business name on Companies House (free at beta.companieshouse.gov.uk) if they trade as a limited company. For sole traders, search their name and trading address together on Google Maps. If neither produces anything concrete, ask them directly for a full business address and verify it independently.
High-pressure urgency tactics
"I can only do this price today" is a manipulation technique, not a commercial reality
Legitimate roofing contractors are typically booked out weeks in advance. They do not need to pressure anyone into a same-day decision. Any pressure framing — "I have leftover materials from another job so I can do it cheap if you decide now," "another customer just cancelled so I can start this afternoon," "this price is only valid today" — is designed to prevent you from doing the one thing that exposes a cowboy: getting a second opinion.
The urgency is always artificial. Even if your roof has a genuine problem that needs addressing soon, a few days to get three quotes and check the contractor's credentials will not make the situation materially worse. Any trader who insists otherwise is not being honest with you.
"I appreciate the offer, but I make a point of getting at least three quotes for any roofing work and checking credentials before I commit to anyone. If that means your price changes, I understand — but I won't be rushed on this."
They cannot show you completed work nearby or provide references
Any roofer with years of local experience should be able to point to work you can see
An established roofing contractor operating in your area will have completed jobs nearby. Legitimate contractors are usually happy to point you to streets where they have worked and, for larger jobs, to provide contact details for recent customers who are willing to speak to you. If a contractor claims years of experience but cannot name a single local job or provide a single reference, the claimed track record does not exist.
This is particularly worth checking for larger jobs — full re-roofs, flat roof replacements, chimney rebuilds. For a minor repair, references are less critical, but still worth requesting if the quote is significant.
"Have you done similar work nearby recently? I'd find it helpful to see an example of your finished work — even just being able to drive past a property would give me confidence." A confident, legitimate contractor will say yes without hesitation.
The price is dramatically lower than every other quote
A quote that seems too good to be true usually is — but not always for the reason you expect
It is tempting to focus on overpriced cowboys, but the underpriced quote is often more dangerous. A price significantly below the market rate almost always means one of three things: the contractor is planning to cut corners on materials, they intend to add to the price once work has started and stopping would cost you more than continuing, or they are genuinely inexperienced and do not yet know what the job actually costs.
The target range for a legitimate roofing quote is not the cheapest or the most expensive of three — it is the one where the scope is most clearly defined and the credentials check out. A 15% price difference between good contractors is normal. A 40–50% gap almost always reflects something being left out.
How to verify a roofer before committing — the 5-minute checklist
You do not need to be an expert in roofing to protect yourself. These five checks take less than ten minutes and cover the vast majority of rogue trader risk.
- ✅Google their business name — search the exact name they gave you plus their town. A legitimate business will appear in search results with a consistent web presence, Google Maps listing, and matching address details. No results at all is a warning sign.
- ✅Check Companies House — if they trade as a limited company, search at beta.companieshouse.gov.uk. The registration address and directors should match what they told you. A limited company with accounts overdue or recently dissolved is a red flag.
- ✅Ask for their insurance certificate by email — requesting it in writing means they cannot easily bluff. If they say they will bring it on the day, decline and ask for it now. The certificate should show the insurer, policy number, cover amount, and expiry date.
- ✅Read their Google reviews in full — not just the star rating. Look for specificity, time spread, and whether the reviewer profiles look real. Check if there are any 1-star reviews and how the business responded to them.
- ✅Get a second quote before you decide — even if you are fairly confident in one contractor, a second quote gives you a price anchor and is often the fastest way to expose a contractor whose pricing or scope description does not match the market.
What if you have already paid — and now something feels wrong?
If work has started and you are now concerned, or if a contractor has taken a deposit and stopped responding, act quickly — the earlier you move, the more options you have.
| Your situation | First action | Where to get help |
|---|---|---|
| Paid by credit card, work not done or substandard | Section 75 claim with your card provider | Your credit card issuer directly |
| Paid by debit card, contractor disappeared | Chargeback request to your bank | Your bank — do this within 120 days of payment |
| Paid cash, contractor still contactable | Send a formal letter before action | Citizens Advice: 0808 223 1133 |
| Paid cash, contractor disappeared | Report to Trading Standards, consider small claims | Report via Citizens Advice — they route to Trading Standards |
| Work completed but dangerously substandard | Independent inspection report + formal complaint | NFRC or TrustMark can advise on dispute resolution |
What makes a legitimate roofer different
It is worth being clear that the behaviours above are not universal to the roofing trade. Most UK roofers are skilled, insured, and entirely trustworthy. The red flags in this guide are useful precisely because they stand out against the baseline behaviour of a professional contractor.
A roofer who is genuinely established in your area will have a Google Business Profile with a history of real reviews, a website with a business address, verifiable insurance, and — most importantly — no need to pressure you into anything. Their diary is full. They want work from people who found them and chose them deliberately, not from people who were scared into a snap decision.
If you are a homeowner trying to find that kind of contractor in your area, the fastest route is a local Google search for "[your town] roofer" and filtering by reviews — prioritising businesses with 30+ reviews spread over at least 18 months, with a consistent business address, and responsive to questions before you commit.

Frequently Asked Questions
What is a cowboy roofer?
A cowboy roofer is an unqualified, uninsured, or fraudulent trader who takes payment for roofing work they cannot competently perform — or who disappears after taking a deposit without completing the job. They often target elderly or vulnerable homeowners with doorstep cold calls and use high-pressure sales tactics to prevent comparison shopping.
How do I check if a roofer is legitimate in the UK?
Ask for their full business name and address, proof of public liability insurance, and verifiable reviews on Google or Checkatrade. Check that their company is registered at Companies House if they trade as a limited company. Legitimate roofers will have no issue providing all of these before starting any work.
What should I do if a roofer knocks on my door uninvited?
Do not engage beyond taking their details. Never allow them on your roof to "check" anything — this is a common pretext for causing damage so they can then quote for repairs. Ask for a written quote, tell them you will consider it alongside others, and end the conversation. Legitimate roofers rarely cold-call door to door.
Is it safe to pay a roofer in cash?
Paying cash is not inherently unsafe, but a demand for cash only — especially combined with pressure to pay upfront — is a significant red flag. Always pay by bank transfer or card where possible, which creates a traceable record. Never pay the full amount before work begins; a deposit of no more than 25–30% is standard practice.
What can I do if a cowboy roofer has already taken my money?
Report the trader to Trading Standards via the Citizens Advice consumer helpline (0808 223 1133). If you paid by credit card, you may have a Section 75 claim against the card provider. If paid by debit card, contact your bank about a chargeback. For larger amounts, consider the small claims court. Keep all written evidence, photographs, and any communications with the trader.
Do I need to use a NFRC-registered roofer?
Membership of the National Federation of Roofing Contractors (NFRC) is not a legal requirement, but it is a useful baseline check. NFRC members have passed a vetting process and agreed to a code of conduct. For large jobs — full re-roofs or structural work — choosing a NFRC member reduces your risk considerably.
You deserve a roofer you can actually trust
The best way to avoid a cowboy is to find a contractor who doesn't need to knock on doors — because homeowners in their area already know them. If you're a roofer who wants to be that person, start with a free visibility audit.
