As Tornado Alley Shifts, Storm Guard Sees Storm Damage Surge in Wisconsin and Illinois

The map of where tornadoes hit is changing, and Storm Guard is seeing the effects firsthand. Over the last five to ten years, franchisees in markets typically considered outside traditional Tornado Alley have reported a clear rise in tornadoes and severe storm damage. The change is most pronounced in the brand's northern markets, especially Wisconsin and Illinois.

Northern markets feel the shift most Across Storm Guard's locations, the Madison, WI, and Naperville, IL, markets have seen the most sizeable increase in tornado-related damage and repair demand. In both, storm activity now dominates the season, where by contrast, the brand has not seen the same level of change across its Southern or Eastern markets.

"Our northern markets have told the clearest story,” said Jason Johnson, Performance Coach at Storm Guard. "In places like Madison and Naperville, storm work used to be one part of the business. Now it's what defines the season."

Madison offers the starkest example. Historically, about 80% of the location's business was retail work, such as planned roof replacements. Over the last two years, that mix has flipped: roughly 90% of its work is now storm-related.

"When a location goes from mostly retail to almost entirely storm restoration in two years, that tells you the weather pattern has changed, not just a single bad season," continued Johnson.

Homes outside traditional Tornado Alley are more vulnerable Storm Guard franchisees are also seeing a difference in the kind of damage that occurs. In traditional Tornado Alley, many homes are built with severe weather in mind. In areas that have not historically faced the same level of tornado activity, homes may not be.

The differences can include stud spacing, foundation construction, building materials, and whether a home has a basement or storm shelter. As a result, even a less powerful tornado can cause significant damage where homes were not designed for that kind of weather.

"A tornado that a home in Oklahoma might be built to withstand can do real damage to a home in Wisconsin that was never designed with that risk in mind," said Johnson. "Homeowners in these newer high-risk areas should know their home's weak points before the next storm, not after."

Later-season storms and a growing opportunity While spring remains the core of tornado season, Storm Guard has occasionally seen storms develop later in the year. Southern markets sometimes see activity in September and October, and Denver has experienced later-season storms that historically have been less common.

For Storm Guard, the changing patterns also shape where the brand grows. "These shifts reinforce the opportunity for Storm Guard to keep expanding, both in traditional Tornado Alley markets and in areas seeing more severe weather," said Johnson. "Homeowners in these communities need experienced, local restoration teams they can trust."

Founded in 2003, Storm Guard operates 34 franchise locations across 17 states and continues to expand nationwide. The brand is committed to delivering high-quality exterior services while supporting franchise owners with scalable systems designed to meet growing homeowner demand.
