The short answer
A stranger who knocks to say your tiles are loose or your roof needs work is a warning sign, because genuine roofers rarely find customers this way. Do not agree to anything on the spot. You have a 14-day right to cancel a contract made at home, and you can report suspicious callers to Trading Standards or the police.
Why the knock itself is the warning
Think about the order of events. You did not call anyone, you had no leak and nothing was on your mind. Then a person appears, already knowing what is wrong with a part of your house you cannot see from the ground. A roof is hard to judge from a path, and a genuine tradesperson would not claim to diagnose it in thirty seconds.
The pattern is a business model built on unsolicited visits. The caller needs a quick yes, because a slow, careful decision usually ends with you checking prices and asking a neighbour. So the approach is designed to create urgency before you have a chance to think. Some callers are simply pushy salespeople, and some are outright criminals. From the doorstep, you cannot tell which, so treat all of them the same way.
You owe a stranger nothing, not even a conversation. A polite no, said once, is enough. If they will not leave the property, you can close the door and ring the police on the non-emergency number, or on 999 if you feel unsafe.
The usual lines and pressure tactics
The script varies, but the shapes repeat. Recognising them helps.
- Loose tiles, a slipped ridge or moss that will cause damage, usually with a photograph taken on their phone, which may not even be of your roof.
- We are working next door, so we can do you a special price today only.
- A rock-bottom quote that rises once work starts, because something worse has been found.
- A demand for cash, or for payment in full before they begin, perhaps with a lift to the bank.
- A request to look in the loft, and then to show you something alarming up there.
Moss, a handful of cracked tiles or an ageing ridge are often cosmetic or slow problems, not emergencies. A job that was truly urgent would still wait while you rang two other firms. Anyone who tells you otherwise is selling pressure, not roofing.
If a caller shows you a photograph, ask to see the roof yourself from the ground, and then ask for a name, an address and a written quote. Genuine firms provide these without a fuss. Our page on how to check a roofer shows the quick checks to run afterwards.
Your 14-day right to cancel
If you do sign something at home, the law is on your side. The Consumer Contracts Regulations 2013 give you 14 days to cancel an off-premises contract without giving a reason. A contract agreed in your own house, or on your doorstep, counts. The period ends 14 days after the day you made the contract.
A trader must not start the service inside those 14 days unless you ask them to, and for a contract made at home the request must be in a letter or an email. If the work started without it, or if you were never told about your right to cancel, you may be in a stronger position than you think. The full explanation sits on our page about the cooling off period.
Cancel in writing, keep a copy, and ask for any money paid to be returned. If you paid for work that has begun, you may owe an amount in proportion to what was done, which is a reason to cancel early rather than late.
What to do if you have already agreed
Do not panic, and do not let the caller start. If they are on site, you can still say you want a day to think. Ring the number on their paperwork, and check that it works. Write down everything you can remember: the name given, the vehicle, the registration, what was said and what you signed.
If money has changed hands, contact your bank at once. If you paid by card or bank transfer, it is worth asking whether the payment can be stopped or reclaimed. Take photographs of any work done, and of the roof as it stands now, from the ground or from a safe window.
Then arrange an independent opinion from a firm you have chosen yourself. A survey with pictures shows what is genuinely wrong, if anything. Many doorstep faults turn out to be minor or nonexistent. Our guide to the roofing quote checklist covers the details a proper written quote should contain, so you can compare.
Who to tell about a doorstep roofer
Reporting helps other households. Contact Citizens Advice's consumer service, who pass on reports to Trading Standards, or contact your local council's Trading Standards team directly. If you think a crime has taken place, such as fraud or intimidation, tell the police. For scams, the police also run a national fraud reporting service.
Give as much detail as you have: the date, the street, a description of the person, the vehicle and any phone number or business name. Even a partial registration number is useful. Reports build a picture of who is operating in an area, and they can lead to action.
Neighbours matter too. Older people are often targeted, so a quick word to relatives and the people next door can save someone a great deal of money. If you know an elderly neighbour who lives alone, a friendly mention of these tactics is worth a few minutes.
Getting roof work done the safe way
If you think your roof does need attention, begin it yourself. Pick a firm, ring it and ask for a survey. Skyline Swindon Roofing surveys first, then sends the price in writing with pictures of your roof, and our own work comes with a 10-year workmanship guarantee on paper. Often a small repair is enough.
It also helps to know what the roof is made of, since a method that suits one covering can harm another, as roofing materials compared explains. If you are unsure whether a problem is real, ask. A good firm tells you plainly, and sometimes nothing needs doing yet. The phone, WhatsApp and the website form all reach us.
