Minnesota roofing marketing for 176 freeze-free days, summer hail and a strict claim law

Minnesota wants your state license number wherever you advertise. A missing number is easy for a rival or a homeowner to spot, so fix it once, everywhere.

Minnesota's license number rule is broad. It names signs and vehicles. It names business cards, flyers and brochures. It also names websites and internet ads, so a Google or Facebook ad counts.

DLI's contractor FAQ adds two details. The law sets no size or spot for the number. The letters in front tell homeowners which license you hold: RR for a residential roofer, BC for a building contractor and CR for a remodeler.

• A roofer license covers the roof. The same FAQ says a roofer license does not allow gutters, downspouts, soffits or fascia. A roofer-only shop should drop "roofing and gutters" from its ads and profile, or hold a license that covers both.
• The name has to match. Working under a name other than the licensed one is a listed deceptive practice under DLI's contractor rules, unless an assumed name is filed and given to DLI. Check the truck wrap and the Business Profile name against the license.
• No city license on top. DLI's FAQ also says cities and counties cannot require a local license for work the state license already covers.

The license itself is a trust line worth printing. A licensed roofer posts a $15,000 surety bond and carries liability insurance of at least $300,000 per occurrence, per DLI's roofer license page.

Platforms look too. Google checks a state license for Local Services Ads where local law calls for one, per its roofing requirements. The Minnesota page covers DLI licensing across trades. This is the roofing detail under it.

Most Minnesota storm work arrives in four summer months. The rest of the year, your ads should sell something other than hail.

We counted NOAA's Storm Prediction Center report files for 2021 to 2025. Minnesota logged 1,974 hail reports, sixth among states. In the Storm Prediction Center count, May held 23.2% of them, June 19.3%, July 24.5% and August 14.8%. Of those reports, 208 were stones two inches or larger. The Storm Prediction Center files also list 2,097 damaging wind reports, with 26.0% in May and 24.3% in June.

The years swing hard. The same files hold 246 hail reports in 2021, 701 in 2022 and 262 in 2025. So we would set a base summer budget and keep a reserve for a heavy year, rather than plan off last July.

Storms keep a clock as well. The state DNR's tornado summary says over 85% of Minnesota tornadoes have come between May and August, and that most touch down from mid-afternoon into the evening. So the calls start late in the day. Someone should answer into the evening on storm days, or an AI receptionist should book the inspection after the office closes.

One ad rule bites in storm week. Google's sensitive events policy bars using a declared disaster's keywords to pull traffic. Bid on the damage, such as "hail damage roof inspection", not on the name of the storm.

After a storm, canvassing and quick quotes bring in work, and Minnesota regulates both. A crew that skips the paperwork can lose the sale a few days later.

Minnesota's three-day cancel law gives a buyer until midnight of the third business day to cancel a home solicitation sale.

The law's definitions decide which visits count. A repair visit the homeowner asked for is outside the rule, but a new roof sold on that visit is not. A visit to quote a specific purchase escapes it only with a dated, signed statement in the homeowner's own handwriting waiving the right.

The seller also has to tell the buyer out loud and hand over a boldface notice with a cancellation form.

Canvassers need a script. The Attorney General's door-to-door page says a salesperson making cold calls at the door must state their name, the business and what they are selling.

A State Fair or home show booth is covered too, under federal law. The FTC's Cooling-Off Rule reaches sales of $130 or more at temporary spots such as fairgrounds and convention centers. So a roof contract signed at a booth needs the three-day notice.

Prices in ads have a Minnesota rule as well. Since January 1, 2025, the price transparency law says a price in an ad has to carry every fee the buyer cannot avoid. A service priced by its details, like a roof repair, complies by naming the price factors and any mandatory fees, and by saying the total may vary. A "repairs from" price needs that line beside it.
