Door knocking is legal everywhere in the United States, but almost every city regulates it. The rules that actually bite a roofing crew are local ones: a solicitor's permit, the hours you're allowed to knock, and whether a posted no-soliciting sign carries the force of an ordinance. On top of that sits one federal rule — the FTC's three-day cooling-off right — and, in storm states, a layer of statutes written specifically about contractors and insurance claims.
None of this is complicated. It is just scattered across a thousand municipal codes, which is why most crews learn it from a police officer standing in a driveway.
This guide covers what applies, where to look it up, and the handful of habits that keep a canvassing operation out of trouble. It is a plain-English summary, not legal advice — verify the rules for the specific city you're working and have a lawyer read your contract.
The four layers of rules
Door-to-door selling is governed by four separate layers, and they stack. Complying with one says nothing about the others.
| Layer | Who writes it | What it typically controls |
|---|---|---|
| Municipal | City or county | Solicitor permits, allowed hours, no-soliciting signs, do-not-knock registries |
| State | Legislature | Home-improvement contractor licensing, extended cancellation windows, storm-specific contract language, deductible rules |
| Federal | FTC | The three-day right to cancel a sale made at the home |
| Private | The HOA | Gated communities and covenants that ban soliciting outright on private roads |
The layer most crews underestimate is the last one. A gated community's roads are private property, and a rep who drives past the gate is trespassing regardless of what the city ordinance says.
Layer 1: The solicitor's permit
Most cities require a permit to sell door to door, and most roofing crews don't have one.
The permit goes by different names — solicitor's permit, peddler's license, canvasser registration, transient merchant license — and is usually issued by the city clerk's office or the police department. Expect some combination of an application, a modest fee, proof of the company's contractor license and insurance, and a background check on each rep.
Two patterns to watch for:
- Per-company vs. per-rep. Some cities license the business once. Others license every individual and require them to carry a photo badge and show it on request. If you hire eight canvassers the week after a storm, the second pattern is a real scheduling problem.
- Processing time. A few days is common; a couple of weeks is not unusual. The whole value of storm canvassing is being there in the first week, so a permit that takes ten days to issue arrives after the good doors are gone.
The practical answer is to pull permits for the cities inside your normal working radius before the season, not after the hail. It costs very little and it removes the single most common reason a canvassing day gets shut down at 11am.
Where to look it up: search the city's name plus "solicitor permit" or "peddler license", or call the non-emergency line at the police department and ask. Ten minutes on the phone beats a citation.
Layer 2: No-soliciting signs and do-not-knock lists
A posted no-soliciting sign means one of two things depending on where you are:
- In a city with a sign ordinance, knocking at that door is an offense. Some cities go further and maintain a do-not-knock registry — an official list of addresses that opted out, which the city gives you when it issues your permit. Knocking a registered address is a violation whether or not a sign is up.
- In a city with no ordinance, the sign is not itself a law. Ignoring it is not automatically illegal, but it is an invitation for the homeowner to call the police and report a trespass, and the officer will side with the resident.
Either way the commercial math is the same. Skipping a posted house costs a rep four seconds. Getting a police car dispatched to a street costs you that street, and often the neighborhood, because word travels faster in a subdivision than any pitch you have.
Train reps to treat the sign as binding everywhere and stop thinking about it. Log the address as a skip so nobody on the team knocks it next week either — that is one of the quieter benefits of logging every door as a canvassing pin instead of keeping a tally in your head.
Layer 3: Hours, and the last hour of daylight
Ordinances usually permit soliciting between roughly 9am and somewhere between sunset and 9pm, and many prohibit it on Sundays and federal holidays.
That cut-off matters more than it sounds, because the hour before dark is the most productive hour of a canvassing day — it is when people are home. A city that ends soliciting at sunset has effectively removed your best window, and a crew that doesn't know it is knocking illegally at exactly the time it is most likely to be noticed.
Check the hours for every city you work, and set them as a hard rule for the team rather than a guideline. Our complete door-knocking guide covers how to build a route around the legal window instead of fighting it.
Layer 4: The FTC's three-day cooling-off rule
This is the one federal rule that applies to essentially every roofing contract signed at a kitchen table, and it is widely misquoted in the field.
What the rule actually says, per the FTC's own consumer guidance:
- It covers sales of $25 or more made at the buyer's home, workplace, or dormitory — and $130 or more at a seller's temporary location such as a hotel room or fairground.
- The buyer can cancel until midnight of the third business day after the sale, for a full refund, without giving a reason.
- Saturday counts as a business day. Sundays and federal holidays do not. A Friday signing runs to midnight Tuesday.
- The seller must tell the buyer about the right at the time of sale, and must hand over two copies of a cancellation form plus a dated contract or receipt showing the seller's name and address and explaining the right to cancel. If the presentation was in Spanish, the paperwork has to be in Spanish too.
- If the buyer cancels, the seller has 10 days to refund the money and return any check or trade-in.
Two exclusions worth knowing. The rule doesn't cover a sale made because the homeowner asked you to come repair or maintain something — but anything they buy beyond that repair request is covered. And the rule doesn't cover sales involving insurance itself; a roofing contract is a home-improvement sale, not an insurance sale, so it is covered even when the job is being paid for by a claim.
Why the good crews like this rule. A contract signed by a homeowner who felt cornered gets cancelled on day three anyway. Reading the cancellation right out loud, handing over the forms, and saying "take the three days, that's yours" reads as confidence, not weakness, and it removes the single biggest objection at the door — this guy is trying to rush me. See our objection-handling scripts for how to work that into the close instead of around it.
The storm layer: rules written about you specifically
Storm restoration draws extra legislative attention, because every major hail event is followed by a wave of complaints about crews that vanished. A number of states have statutes aimed at roofing contractors specifically. The recurring themes:
- Extended cancellation windows tied to the claim. Several states let a homeowner cancel a storm-restoration contract until some number of days after the carrier makes its coverage decision — not after signing. A contingency agreement signed on the day of the knock may be cancellable weeks later, by design.
- Required contract language. Statutes commonly require the cancellation notice to appear in a specified font size, in a specified place, with specified wording. Getting the typography wrong can void the contract.
- Deductible rules. Waiving, absorbing, or "eating" a homeowner's deductible is illegal in many states and is insurance fraud in several. It is also still one of the most common things reps say at the door. Don't.
- No adjusting without a license. Documenting damage, meeting the adjuster on the roof, submitting your estimate, and requesting a supplement for missed line items are contractor activities. Negotiating the settlement on the homeowner's behalf is public adjusting and requires a separate license in most states.
- Registration for out-of-state contractors. Some storm states require crews from elsewhere to register before working a declared disaster area.
If you chase storms across state lines, this layer is the one that will cost you real money, and it is the layer a generic sales-training course will never mention. It is also why the storm chaser label sticks to the whole industry — the statutes exist because a minority earned them.
What "compliant canvassing" looks like day to day
None of the above requires a compliance department. It requires six habits.
- Pull permits ahead of the season for every city in your normal radius, and keep copies in the truck.
- Give every rep a badge and a business card with a local phone number. Reps who look official get fewer police calls.
- Skip posted houses, always, and log them so nobody re-knocks them.
- Set the knocking window as a team rule, not a suggestion, and build routes around it.
- Read the cancellation right out loud at signing and hand over the forms. Every time.
- Never mention the deductible except to say the homeowner is responsible for it.
Those six things also happen to be what separates a company homeowners recommend from one they warn their neighbors about. Compliance and reputation are the same project.
Where to look up the rules for a specific city
There is no national database, so this is a per-city job:
- Municipal code: search the city name plus "solicitation ordinance" or "peddlers and solicitors". Most cities publish their code online through a municipal-code hosting service.
- Permits: the city clerk's office, or the police department's non-emergency line.
- State contractor rules: your state's contractor licensing board or department of commerce.
- State storm-contract statutes: your state attorney general's consumer-protection page, which usually publishes a post-storm advisory naming the exact statute.
- Federal: the FTC's Cooling-Off Rule page.
Build the list once, keep it in a shared doc, and update it when you enter a new market. It takes an afternoon and it is the cheapest insurance in the business.
The bottom line
Door knocking is legal. It is also the most regulated way to sell a roof, and the regulations are almost entirely local. Pull the permit, respect the sign, knock inside the hours, hand over the cancellation form, and leave the deductible alone — and the legal layer stops being something you think about at all.
What's left is the actual work: knowing which streets took hail, covering them without double-knocking, and logging what happened at every door. That's what HailMate's canvassing tools are for — the hail map shows you the verified damage, and every knock lands on the map with an outcome attached.
