Scam simulator · At your door

The Friendly Roofer at the Door

A polite man knocks and says he’s spotted loose tiles on your roof. He offers to take a look for free. Practice what to do, and see how a friendly chat on the doorstep can end with thousands of dollars gone and a roof that still leaks.

The simulator

Why it matters: A widow in her 80s in England was told her roof tiles were loose and quoted £14,200 for repairs. An independent surveyor later found no significant problems, just a small maintenance job costing no more than £1,250. The two traders were jailed in February 2026. (Buckinghamshire Council Trading Standards, February 2026)

It’s a sunny Thursday morning and you’re at home on your own. There was a strong wind last week, and you’ve been meaning to get someone to look at the gutters.

Below, each step shows what you'd see, the choices people make, and why each one is safe or risky. The summary at the end tells you what to look for and what to do.

You'll see each message or call as it would really look. Choose what you'd do, and you'll find out why. Nothing here is real: no messages are sent and nothing you choose leaves your device.

  1. Step 1 of 7 First contact

    There’s a knock at the front door. A friendly man is standing on the step, and a van is parked on the street.

    Practice screen At your front door

    A man in his forties wearing a bright safety vest and holding a clipboard. Behind him is a white van with a ladder on the roof rack. There’s no company name on the van.

    1. Man: “Morning. Sorry to bother you. We’re working on a roof a few doors down, and from up there we noticed some loose tiles on yours.”
    2. Man: “Probably that wind last week. I’ve got the ladder right here. I can pop up and take a look for you, no charge. Won’t take five minutes.”

    What do you do?

    Not sure? Show a hint

    You didn’t call anyone. Who decided your roof needs work?

    1. Say yes. It’s free, he’s polite, and I’d rather know if there’s a problem.

      Risky choice

      This is what he’s hoping for. Once he’s on your roof, only he can see what’s up there, and whatever he “finds” will be hard to argue with. The free look costs him nothing, because it’s how the sale begins.

    2. Take his business card and say I’ll think about it.

      Better, but not the safest

      Better than saying yes, because you haven’t agreed to anything. But anyone can print a card, and he may keep talking or come back. A polite no is simpler, and if you’re worried about the roof, you choose the roofer.

    3. Say “No thank you, I don’t deal with people who knock at the door,” and close the door.

      Safe choice

      That’s the safest answer. You don’t need to give a reason or be rude. If you’re worried about the tiles, ask a family member to help you find a local roofer you’ve chosen yourself.

    Red flags at this step

    • A stranger knocks to tell you about a problem you didn’t know you had
    • A free look or inspection
    • “We’re working a few doors down”

    What's really going on

    This is a typical start to a doorstep roofing scam. In a case from Buckinghamshire, England, two traders told a widow in her 80s that her tiles “were loose and would need replacing”. Age UK lists traders who say they’ve noticed something wrong with your home as one of the common doorstep scams aimed at older people.

  2. Step 2 of 7 The hook

    Many people do let him look, because it’s free and he seems kind. Here’s what happens. Ten minutes later he climbs down holding something.

    Practice screen At your front door

    He’s holding a dark, crumbly piece of wood about a foot long. On his phone he shows you photos of cracked tiles and a wet, rotten beam.

    1. Man: “Look at this. That came off your roof. The wood under the tiles is rotten right through.”
    2. Man: “Honestly, it’ll leak with the next rain. And once water gets in, you’re looking at ceilings coming down.”

    He's showing you the wood and the photos. What do you think?

    Not sure? Show a hint

    Did you see him take that wood from your roof? Can you tell whose roof is in the photos?

    1. Believe him. He’s holding the proof, and I don’t want my ceiling coming down.

      Risky choice

      That’s how most people would feel, and it’s what the wood is for. You didn’t see where it came from, and the photos could be of any roof. Worried and in a hurry is exactly how he wants you to decide.

    2. Ask him to hold the ladder so I can climb up and see for myself.

      Risky choice

      Please don’t. Climbing a ladder is a real risk, and even from up there it’s hard to judge how serious a problem is. Checking a roof is a job for a roofer you have chosen, not the man who wants to sell you the repair.

    3. Thank him, say I’ll have my own roofer check it, and close the door.

      Safe choice

      That’s right. If there really is a problem, a roofer you choose will find it and give you a written quote. A second opinion costs little, and it can save you thousands.

    Red flags at this step

    • “Proof” you can’t check yourself: a piece of wood, or photos on his phone
    • Frightening warnings: “it’ll leak with the next rain”

    What's really going on

    In the Buckinghamshire case, the traders came down with “a piece of rotten roof batten which they claimed had come from her roof” (a batten is a strip of wood that holds the tiles) and said more significant work was needed. An independent surveyor later found no significant issues with her roof. You have no way of knowing where a piece of wood came from, or whose roof is in a photo.

  3. Step 3 of 7 The pressure

    Suppose you’re still listening. He puts the wood down and writes something on his notepad.

    Practice screen At your front door

    He tears off a page from his notepad with a price on it. There’s no company name, address or license number on it.

    1. Man: “A job like this is normally $9,600. But we’ve got tiles and timber left over from the job down the street, so I can do it for half. $4,800.”
    2. Man: “The catch is it has to be today, while the crew and the materials are here. No need for paperwork. We’re a family business. A handshake is fine by me.”

    What do you do?

    Not sure? Show a hint

    Would a fair price disappear if you took a day to think about it?

    1. Shake on it. Half price is a good deal, and more rain is coming.

      Risky choice

      The “normal” price is made up, so there’s no real saving. With no written quote, there’s no record of what was agreed, what work will be done, or who you’re dealing with.

    2. Ask for his license number and a written quote, and tell him I’ll think about it.

      Better, but not the safest

      Much better. A license can be checked on the official register where you live, and a written quote is a record. But even a real license doesn’t make a doorstep price fair, so get other quotes from roofers you find yourself.

    3. Say no thank you. If the roof needs work, I’ll get written quotes from two or three licensed roofers I find myself, and talk it over with family.

      Safe choice

      That’s the way to do it. Quotes from roofers you choose, compared side by side, show you what the job really needs and what it should cost. Talking it over with someone you trust takes the pressure off.

    Red flags at this step

    • “Materials left over from another job”
    • Half price, but only if you agree today
    • No written quote, no license number and no address

    What's really going on

    The FTC lists these as signs of a home improvement scam: knocking on doors because they’re “in the area”, saying they have “materials left over from a previous job”, and pressuring you for an immediate decision. It advises getting written estimates, comparing several, and checking a contractor’s license with your state or county government. The Buckinghamshire traders quoted £14,200.

  4. Step 4 of 7 The ask

    Suppose you say yes. He’s pleased, and says his crew can start this afternoon. Then he mentions one more thing.

    Practice screen At your front door

    He’s standing by the van with the engine running and the passenger door open.

    1. Man: “We just need a deposit to buy the materials. Half now, so $2,400. Cash is best.”
    2. Man: “If you don’t keep that much at home, no problem at all. I’ll run you down to your bank now and wait outside. We’ll have you back before lunch.”

    What do you do?

    Not sure? Show a hint

    A few minutes ago he had materials left over. Why does he need cash to buy them now?

    1. Get in the van. It’s kind of him to drive me, and the bank is only ten minutes away.

      Risky choice

      Once you’re in his van, you’re on his schedule and away from anyone who could help. At the bank, he’s waiting outside, so it’s much harder to change your mind. The cash goes straight to him, and once it’s handed over it’s very hard to get back.

    2. Write him a check instead of taking out cash. It’s safer.

      Risky choice

      A check feels safer, but it only helps if you can stop it in time. In the Buckinghamshire case, the widow’s £8,000 deposit check was made out to one of the brothers personally. It was cashed right away and the money taken out in cash.

    3. Say no. I never go to the bank with a tradesperson. I close the door and call a family member.

      Safe choice

      That’s exactly right. A real business doesn’t drive customers to the bank for cash. If he won’t take no for an answer, or won’t leave, call the police.

    Red flags at this step

    • An offer to drive you to the bank
    • Cash only, or a check made out to a person instead of a company
    • A big deposit before any work is done
    • He had materials left over, and now needs money to buy them

    What's really going on

    In April 2026, police in Sydney, Australia warned about a man who told a 73-year-old woman her building’s roof needed urgent repairs. The next day he drove her to her bank and pressured her into writing a check for tens of thousands of dollars. She canceled the check and called the police. Their advice is simple: “Don’t accompany them to a bank.”

  5. Step 5 of 7 The ask

    Suppose the work begins. An hour later there’s another knock, and he looks serious.

    Practice screen At your front door

    Tiles are stacked on your lawn and part of the roof is open to the sky. He’s dusty and frowning.

    1. Man: “It’s worse than we thought. The wood’s rotten right across the back. If we just put the tiles back, the whole lot could come down in the next storm.”
    2. Man: “We’ll have to replace it. That’s another $5,200. We’re up there already, so it makes sense to do it now.”

    What do you do?

    Not sure? Show a hint

    With the roof open, who holds all the cards? Do you have to agree to anything extra?

    1. Agree. The roof is open, so I can’t really say no now.

      Risky choice

      That’s the trap. The price has now more than doubled, and there may be more “problems” still to come. Each yes makes the next one feel harder to refuse.

    2. Ask him to show me the rotten wood first.

      Risky choice

      He’ll be happy to show you a piece of rotten wood. As before, you can’t tell where it came from or how serious the problem is. It only makes the new price feel more believable.

    3. Tell him I won’t pay anything more. Then call a family member, and get a roofer I choose myself to check what’s been done.

      Safe choice

      Well done. You don’t have to agree to extra work, however it’s put to you. A second opinion will show what really needs doing, and a family member can help you deal with him.

    Red flags at this step

    • New “problems” found once the work has started
    • The price keeps going up
    • Pressure because the roof is “already open”

    What's really going on

    Finding new problems once the work has started is a common part of these scams, because it feels impossible to say no with your roof open. You can say no, and you may even be able to cancel the whole agreement. In the US you usually have three business days for most sales made at home, and in the UK 14 days. In Australia you have 10 business days, and during that time an uninvited seller generally isn’t allowed to take payment or start work.

  6. Step 6 of 7 Afterwards

    Suppose someone did pay. Two weeks later, after a night of heavy rain, they notice something on the bedroom ceiling.

    Scene

    Two weeks later. There’s a brown damp patch spreading across the bedroom ceiling. The phone number he wrote on a scrap of paper goes straight to voicemail. The van hasn’t been back.

    What do you do now?

    Not sure? Show a hint

    Who can actually help now? Be wary of anyone who offers to get your money back for a fee.

    1. Keep trying his number, and wait for him to come back and fix it.

      Risky choice

      It’s natural to hope he’ll come back and put it right. But a trader you can’t reach after you’ve paid may never return, and every week you wait makes it harder to stop a payment or find him.

    2. Search online for a company that promises to get money back from rogue traders, and pay their fee.

      Risky choice

      Be careful. People who have lost money are often targeted again by “recovery” services that charge a fee and recover nothing. Reporting a scam to your bank and the authorities is free.

    3. Call my bank, report the trader, and ask a licensed roofer I choose to check the roof. Tell family and neighbors too.

      Safe choice

      That’s the right move. Your bank may be able to stop a check or payment that hasn’t cleared. Reporting helps the authorities catch these crews, and warning your neighbors protects them too.

    Red flags at this step

    • A trader you can’t reach once you’ve paid
    • Work that fails at the first heavy rain

    What's really going on

    NSW Fair Trading in Australia described a homeowner who paid $5,200 for roof cleaning, sealing and painting. Two weeks later it rained, water leaked inside the house, and the trader couldn’t be contacted. Reporting does make a difference: the Buckinghamshire traders were investigated by Trading Standards and jailed in February 2026.

  7. Step 7 of 7 Afterwards

    A few weeks later, there’s another knock. It’s a different man, but he seems to know all about your roof.

    Practice screen At your front door

    A younger man with a clipboard. A different van is parked outside, with a phone number painted on the side.

    1. Man: “Afternoon. The guys who did your roof asked us to stop by. Your gutters and chimney need doing before winter.”
    2. Man: “Since you’re already a customer, we can do you a good price. I just need a quick look out the back.”

    What do you do?

    Not sure? Show a hint

    How does a stranger know about your roof? What happens if you say yes this time?

    1. Let him look. Maybe his crew can fix what the first one got wrong.

      Risky choice

      This is often the same crew, or people they’ve passed your address to. The “good price” for a customer is the same trick as the half-price deal the first time.

    2. Say no, but take his flyer in case I need the gutters done later.

      Better, but not the safest

      You haven’t agreed to anything, which is good. But keeping the flyer leaves the door open, and he now knows you’ll talk to him. If you need gutters done later, choose the tradesperson yourself.

    3. Say no through the door, and call the police if he won’t leave. Then report it and warn the neighbors.

      Safe choice

      That’s right. You don’t have to open the door to anyone you weren’t expecting. Reporting the visit, with the van’s description and number, helps the authorities and your neighbors.

    Red flags at this step

    • A return visit, or new traders who already know about your roof
    • “Since you’re already a customer”

    What's really going on

    Once someone has paid a doorstep trader, they may be visited again by the same crew or by others who have been given their address. In the UK, Age UK suggests putting up a “No cold callers” sign, which you can get from your local council or print yourself. It makes it easier to say no, and to close the door.

What really happened

The man wasn’t working on a roof down the street. Crews like his work their way along streets, and they often target older homeowners, especially people who live alone. The loose tiles, the rotten wood, the half-price deal and the ride to the bank were all part of the script. The deposit was the goal, and any work was quick and poor, if it happened at all. Saying no at the door, and choosing your own tradespeople, stops it at the first step.

Doorstep roofer: what to look for and what to do

Remember: Never agree to work from someone who knocks on your door. If something needs fixing, choose the tradesperson yourself, get it in writing, and never go to the bank with a trader.

What to look for

  • Someone knocks to say they’ve noticed a problem with your roof, gutters or driveway
  • A free look, then “proof” you can’t check, such as a rotten piece of wood or photos on a phone
  • Materials “left over from another job”, half price, today only
  • No written quote, no license number and no business address
  • Cash only, a check made out to a person, or an offer to drive you to the bank
  • New problems found once the work has started, and a price that keeps going up
  • A return visit, or new traders who already know about your home

What to do

Someone knocks offering to fix something
Say “No thank you, I don’t deal with people who knock at the door,” and close the door. You don’t need to give a reason.
You think your roof really does need work
Find a roofer yourself, through people you trust. Get two or three written quotes and check each roofer’s license on the official register where you live.
You do hire someone for repairs
Get a written contract, don’t pay in cash, and pay in full only after the work is done and you’re happy with it. Paying by credit card gives you some protection.
A trader wants cash up front or offers to drive you to the bank
Say no, close the door and call a family member. If they won’t leave, call the police.
Work has started and they say they’ve found more problems
Don’t agree to anything extra. Ask a family member, and a roofer you choose yourself, to check.
They come back, or new traders turn up
Don’t open the door. Report it, tell your neighbors, and think about a “No cold callers” sign.

If you've already paid, clicked or shared details

Don't be embarrassed. These scams are run by professionals, and acting fast gives you the best chance of stopping the damage.

  1. If they’re still there, pushing you to go to the bank or refusing to leave, call the police (911 in the US and Canada, 999 in the UK, 000 in Australia, 111 in New Zealand, 999 or 112 in Ireland).
  2. Call your bank straight away to stop the check or payment. The woman in Sydney canceled her check in time.
  3. You may be able to cancel. In the US, the FTC’s Cooling-Off Rule usually gives you until midnight of the third business day to cancel a sale of $25 or more made at your home, and the seller must give you a cancellation form. In the UK you usually have 14 days to cancel a contract made at home. In Australia you have 10 business days to cancel an uninvited sale. Cancel in writing and keep a copy.
  4. Report the trader (see below), with a description of the people, the van and any phone number. Your report may protect your neighbors.
  5. Ask a licensed tradesperson you choose to check the work, and talk to your home insurer before signing anything with another contractor.
  6. Tell family and neighbors. These crews often work a whole street.

  • Secrecy and hurry are the giveaways. Anyone who tells you not to tell your bank or family, or to act right now, is working against you.
  • Tell someone. Talk it over with a family member, a friend or your bank before you pay anyone you didn’t plan to pay.
