The knock about your roof

The story below is a composite, built from two federal prosecutions and FTC and AARP warnings, cited throughout. No real person is described.

He was in the kitchen when the doorbell rang. Two young men stood on the step, polite and a little sunburned.

They'd been working on a house down the street, they said, and noticed a hole in his roof. Water would get in. They could patch it this week, and clear the moss while they were up there.

He hadn't been on that roof in fifteen years. He couldn't see what they saw. And a crew already in the neighborhood, offering to fix a real problem before it got worse, sounded like good luck. He wrote a check.

The next day they found more. A crack in the foundation. It needed a special repair, and it couldn't wait. They dug trenches in the yard and poured concrete. He could watch the work happening. Each day there was a new check.

Then came a charge for "taxes." Then a request to wire money for building supplies.

That's close to what happened in a case the Justice Department described in 2024. The roof had no hole. The foundation wasn't failing. The trenches and concrete were there to make it look like work was being done.

The pattern

This is the home repair scam, and it runs on one thing: you can't easily check your own roof.

Honest people knock on doors all the time. A neighbor, a kid selling candy, a real company leaving a flyer. The knock isn't what's wrong. What's wrong is a stranger who finds a problem you can't see and needs a decision today.

The price is where it shows. It starts small, so saying yes feels safe. Then it grows. In a 2026 Rhode Island case, a contractor told a homeowner in his 80s he'd noticed cracks in the foundation while working nearby. He collected $9,500, then said more damage had turned up and asked for another $80,000. An inspector later found no need for that work. The same release says he often did or suggested small repairs first, then claimed bigger work was urgent.

It follows the weather, too. After a storm, the FTC warns, scammers ask you to pay for everything up front, claim they don't need a license, and ask you to sign over your insurance check.

Where it was visible

They came to you. AARP puts it plainly: a good contractor is busy and isn't going door to door looking for work.

They were "in the area." Working down the street, or with material left over from another job. The FTC lists both as signs of a scam.

The problem was somewhere you couldn't look. A roof, an attic, under the house. Our home repair page notes that some crews make the damage while they're up there.

The price kept moving. Each "discovery" came with a new check.

Nothing was in writing. No written estimate, no contract, no license number.

And the one that's genuinely hard to see: real work was happening. Trenches, concrete, a crew in the yard. Watching work get done feels like proof. In that case, it was the cover.

What actually stops it

Don't decide at the door. You can say "I don't hire at the door" and close it. That's not rude.

Find your own contractor. Ask people you trust. Check that the company is licensed and insured through your state or county, as the FTC advises. Get written estimates from more than one.

Get it in writing before any work starts. The FTC says a contract should list the license number, the start and finish dates, the work, and the cost. Fill in every blank before you sign.

Don't pay it all up front, and don't pay in cash. Pay by check or credit card, and hold the final payment until the job is done right.

Know your three days. Under the FTC's Cooling-Off Rule, most sales made at your home for $25 or more can be canceled until midnight of the third business day. The seller must give you a cancellation form. Send it by certified mail. Two limits: it doesn't cover a repair or maintenance visit you asked for, or a sale needed to meet an emergency. Anything sold beyond what you called them for is covered.

The five signs, in this case

The five signs mostly fit, with one honest exception.

It came to you. A knock you didn't invite, about a problem you didn't know you had.

It moved you fast. It can't wait. Today's price. Water will get in.

It wants a transfer. Cash, a check made out a strange way, and, near the end, a wire.

It asks you to keep it quiet is the weak one here. Most crews don't ask for secrecy at the start. It tends to show up later. In one North Carolina case, the man urged a victim not to contact the authorities about unfinished work.

It keeps you on the line. Here the line is your front yard. In the 2024 case, they came back each day for another check.

And the three steps still work. Look up the contractor yourself. Call your son or daughter before you sign. Wait a day. A real contractor will still want the job tomorrow.

How common is it

No agency counts door-to-door repair scams on their own. So we can't give you a clean number.

The closest is the FTC's category for home improvement, repair and solar. It got 81,925 reports in 2024. But that bucket also holds furniture that never arrived, warranty fights and solar panels, so it isn't a count of this scam.

What the court cases do show is the size of a single crew. The Rhode Island contractor admitted taking more than $1.5 million from property owners over about four years.

Tell one person

Send this to a parent who owns their home, and ask: what would you say if someone knocked about your roof?

It's a good question to answer over coffee, long before anyone's on the step.

The sentence worth remembering: a real contractor will still want the job tomorrow.

Storms bring out the fake charity as well as the fake roofer. And if you've paid a crew like this, watch for the recovery scam that offers to get it back for a fee.

If this happened to you, or to someone you love

You're not the first and you did nothing stupid. These crews are practiced at being friendly, and at finding the one thing you can't check.

Stop paying. No new check will get the job finished.
Call your bank now if you paid by check or wire, and use the word "fraud." In the 2024 case, quick work by police got the wired money back.
Call your local police on the non-emergency line. Crews like this work a street, and police may already know them.
Report it to your state attorney general's consumer protection office and to the FTC at reportfraud.ftc.gov.
Call the National Elder Fraud Hotline, 833-372-8311, Monday to Friday, 10 a.m. to 6 p.m. Eastern.
Tell one person you trust, and your neighbors too.

If anyone calls offering to get your money back for a fee, that's a second scam.

Verify first.
