Is a door-to-door roofer or driveway paver offering cheap work a scam?
Very often. Doorstep roofers and pavers who say they have leftover materials and offer a large discount are frequently running cowboy trader scams.

Explanation
A common doorstep tradesperson scam involves workers who knock on doors claiming to have noticed damaged roof tiles, a crumbling chimney, or deteriorating driveway, and offer to fix it cheaply using 'materials left over from a job nearby'. After collecting a large cash deposit — sometimes the full amount — they do either minimal or no work, use substandard materials that cause future damage, or disappear entirely. High-quality legitimate tradespeople do not solicit work door-to-door. Always get at least three written quotes from independently verified traders, check reviews through a national tradesperson accreditation scheme, and never pay the full amount upfront.
The 'problem' they spotted is frequently invented or manufactured — some rogue traders photograph other roofs, or dislodge a tile themselves while 'inspecting'. Jobs that do start tend to escalate: a modest repair uncovers 'serious damage' midway, with the price climbing while your roof sits exposed. Older residents are targeted repeatedly, and addresses that pay once are shared among crews as receptive.
A firm, closed-door 'no' is the whole defence. Genuine structural concerns can wait for a verified local tradesperson to inspect, and any legitimate quote survives comparison with two others. If someone claims your roof is dangerous today, that urgency is the sales tactic — a real emergency is confirmed by an independent assessor, not by the person who profits from the work.
Common red flags
- Unsolicited knock with a claim of spotting a problem with your property
- Offer only valid today or before they leave the area
- Request for large cash payment upfront
- No written quote, contract, or business address provided
- Pressure not to call other tradespeople to compare prices
What to do now
- Do not pay anything at the door
- Ask for their trading name, address, and registration number
- Get written quotes from at least three verified tradespeople
- Report aggressive doorstep traders to your local trading standards authority
Frequently asked questions
What if I can visibly see the damage they describe?
The damage may be real but was not caused by the person at the door, or they exaggerated it. Always get an independent assessment from a verified tradesperson before spending any money.
They started work before I agreed a final price — do I have to pay?
Starting work uninvited or without a written agreement is a pressure tactic, not an obligation. Do not hand over cash at the door. Seek advice from trading standards or a consumer rights service before paying anything, and report the trader.
