The easiest way to spot a dodgy roofer is to watch how the conversation is run rather than to look at the roof. Rogue traders rely on a short list of moves: an unexpected knock about a problem you had not noticed, a demand to decide today, a request for a large sum in cash, and nothing on paper. Each move is designed to stop you doing the one thing that protects you, which is taking time to compare.
None of this means a roofer who calls round is automatically dishonest, or that a firm which asks for a deposit is a problem. The pattern matters more than any single act. A roof really can lose tiles in a gale, and a repair that cannot wait does exist. The difference is that a genuine tradesperson can show you the evidence, explain the repair in plain words and give you a written price you can read at the kitchen table.
Below are the scam patterns, the quiet checks that cost almost nothing, the cancellation rights you hold for a contract signed at home, the exception for urgent repairs, and what to do if you have already paid someone who now looks wrong.
The knock about loose tiles
The classic opening is a stranger at the door, or a flyer through it, saying they were working nearby and noticed that some tiles on your roof look loose, a ridge is cracked or the chimney is crumbling. They offer to fix it there and then, often for a price they invent on the doorstep.
Why the pitch works
Few of us can see our own roof, so we cannot check the claim. A trader who points upward and says 'that needs doing before the next storm' is asking you to trust what you cannot check. The pitch also borrows urgency from the weather, which makes waiting feel unreasonable.
What a straight answer looks like
If a roofer sees a real fault, the sensible next step is a survey with photographs, not a start on the spot. We measure and photograph the roof, show you the images of your own tiles, ridge or flashing, and explain what we found. A person who offers no evidence, or whose photographs turn out to show somebody else's tiles, has not earned the work.
Cold calls and doorstep selling
You are free to say no and shut the door. Nothing a caller says obliges you to let them onto the roof, and a trader who climbs up uninvited and comes down with a handful of broken tiles and a story is one to avoid. Ask for a postal address, a number that rings back and a name that matches the van and the paperwork. Our guide on what to ask a roofer before hiring lists the questions that separate a genuine firm from a chancer before any work begins.
Pressure to sign and pay today
Pressure takes several forms, and all of them share one purpose: to move the decision from your head to the trader's timetable.
The special price that expires
'We have scaffolding left over from the next street, so I can do you a good rate if you say yes now.' A discount that disappears when you step away is not a discount. A roof costs what it costs once somebody has measured it, and that figure does not depend on whether you sign in the next ten minutes.
Scare language
Phrases such as 'your whole roof is about to come in' or 'you will have water through the bedroom by Friday' are meant to bypass your reasoning. A careful roofer describes risk plainly and in proportion. A slipped tile can let water in, and we tell you plainly, but one slipped tile is not a collapsing roof, and a good survey explains the difference with photos.
Being rushed through the paperwork
If someone hands you a form and asks for a signature before you have read it, stop. What you sign should show the address, the work, one total price and what is and is not included, such as scaffolding and VAT. Citizens Advice advises collecting at least 3 written quotes before you commit, and a genuine firm will not mind you doing exactly that.
Comparing like with like takes a little effort. Compare the work described, because a price far below the others usually leaves something out, and ask for the survey photographs so a second firm can see the same roof.
Deposits, cash and the missing paper
Money is where a dodgy job turns into a loss. Three habits are worth watching, because they tend to arrive together.
A large deposit up front
Some contractors do need a payment before work begins, usually to order materials. The warning sign is a large sum, asked for in cash, for a job that has no written scope. If a deposit is requested, ask what it buys, put the amount in writing, and keep it tied to materials that can be ordered rather than to a share of the final bill that disappears if the firm does.
Cash only
Paying by bank transfer or card leaves a record that shows who you paid, when and how much. Cash leaves nothing unless you insist on a dated receipt with the trader's full name and address. A trader who will only take cash, and who has no business address or website you can check, is hard to trace later.
No written quote
A verbal figure is not a quote. The absence of paper is the single clearest sign, because everything you might later rely on, from the agreed work to the price, has nowhere to live. Ask for one total price, in writing, after the roof has been looked at. If the figure on the page is not the figure you were told, do not sign.
Three things together should end the conversation: no written price, a large cash deposit and an instruction to decide today.
Your 14-day right to cancel at home
When a contract is agreed away from the trader's own premises, the Consumer Contracts Regulations 2013 give you a cooling-off period. For services, you have a 14-day window to change your mind, starting the morning after you sign, and no reason is needed. Keep a note of the day you signed. A contract signed at your kitchen table after a survey at home is the typical example.
How it works in practice
Citizens Advice says the right applies where the business approached you, not the reverse, and the service costs £42 or more. The 14 days is a minimum, not a ceiling, so a firm can offer longer. Cancel in writing, and keep a dated copy in case there is a later argument.
When the trader has not told you
A trader has to tell you about the right to cancel. If that information was not given, the period is extended, by up to 12 months after the day it would otherwise have ended. If you want work to start inside the 14 days, you have to ask for that in writing you can keep, and you may owe something for the work already done.
Check the paperwork
Read what you were given on the day, including the small print on the back. A form with no mention of cancellation is itself a warning sign. Our short answer on how to cancel a roofing contract goes through the steps in order.
The urgent repair exception
There is one important exception, and rogue traders know it. Under regulation 28(1)(e), the right to cancel falls away when you have asked the trader to come out for an urgent repair. Citizens Advice puts the same point in everyday terms: inviting a business into your home for emergency work means no automatic cooling-off.
Why the wording matters
The exception turns on who asked for the visit. If you ring a roofer because water is coming through your ceiling, you have requested an urgent repair visit, and the 14-day right does not cover that work. If a stranger knocks and persuades you that your roof is an emergency, you did not request anything, and the position is different. Some dodgy firms try to dress a cold call up as an emergency for exactly this reason, so ask yourself who made the first contact.
What to do about a real leak
In a genuine emergency, the leak is dealt with before anything else, and the full repair is agreed afterwards on paper once the cause is clear. A temporary cover and a photograph of the problem let you decide the rest calmly, with time to ask a second firm for a view before you agree to anything larger.
Your other rights stay in place
With or without a cancellation period, the Consumer Rights Act 2015 expects a tradesperson to work with reasonable care and skill, and to finish within a reasonable time where none was agreed. If the work is poor, you can still ask for it to be put right.
If you have already been caught out
People who have paid a rogue trader often feel embarrassed and wait too long. Acting quickly keeps more options open.
Stop and gather what you have
Stop any further payments. Collect the quote, receipts, bank records, messages, photographs of the work and anything showing the trader's name, number and vehicle. Write down the dates while you remember them, and photograph any damage before anyone touches it again.
Get independent advice
The Citizens Advice consumer helpline is 0808 223 1133. It can explain your rights, tell you whether the cooling-off period is still running and suggest a next step. If the work is poor rather than fraudulent, write to the trader, set out what is wrong, say what you want done and by when, and keep a copy.
Get the roof looked at independently
If you are unsure what was done, ask another roofer for a survey with photographs. That record shows the roof as it now stands, which supports any complaint. Traders must also tell you about any dispute-resolution route open to you, which section 308 of the Digital Markets, Competition and Consumers Act 2024 requires, so ask what yours is and note the answer.
If you suspect fraud
Where you believe a crime has been committed, such as a deposit taken with no intention of doing the work, report it to the police and tell your bank. Our page on how to complain about a roofer sets out the order to follow.
