Regional Storm Calendars: When Hail Season, Hurricane Season, and Winter Freeze Actually Overlap on the Map

One National Calendar, Three Regional Ones

A roofing company operating in more than one region is really working three different seasonal calendars at once, not one. Hurricane season has a single, federally defined start and end date that applies the same way from Texas to Maine. Hail season has no equivalent single date; it moves state by state, sometimes month by month within the same state. Winter freeze damage, covered separately in this vertical’s ice-dam and snow-load content, runs on a different mechanism again, tied to cold-weather duration rather than a named storm season at all.

Treating all three as one vague storm season, or worse, treating the whole year as equally exposed everywhere, is the kind of planning mistake that shows up as a marketing budget spent chasing the wrong region at the wrong time of year.

Hurricane Season’s Fixed Dates

The Atlantic hurricane season runs June 1 through November 30 by NOAA and National Hurricane Center definition, a six-month window chosen specifically because it captures roughly 97 percent of all Atlantic tropical storm and hurricane activity. When storms do form outside that window, NOAA notes the activity concentrates in May or December, at the immediate edges of the defined season rather than scattered randomly across the rest of the year.

That fixed window is a genuine planning advantage over hail. A coastal roofing company knows, months in advance, exactly when its highest-risk season opens and closes, which is not true of hail season anywhere in the country.

Hail Season Moves State by State

Hail season does not have a single answer. Per Hail Protector’s analysis of NOAA Storm Prediction Center climatology data, the Texas Gulf Coast sees its first significant hail events as early as late February most years. Move north to the Texas Panhandle, around Amarillo and Lubbock, and the peak shifts to April through early May. Colorado’s peak runs May through June. Keep moving north into Montana, North Dakota, and northern South Dakota, and significant hail does not arrive until June at all, peaking in July, the only Lower 48 region where midsummer, not spring, is the hail-risk peak.

That regional spread means the same national hail statistics, real and useful at the industry level, do not translate into a single answer for when to staff up in any specific metro. NOAA recorded 5,432 hail events nationally in 2025, up from 5,373 in 2024, and 16 states saw 20 percent or more of roofs impacted by severe hail that year, with Kansas leading the country at 51.8 percent and a long-term average annual loss of $2.2 billion. None of those national numbers say when a specific metro’s season starts.

Overlaying the Two Calendars, Region by Region

The table below lines up the regional hail windows against the one fixed hurricane window, region by region, so the gap between a national statistic and a local planning date is easier to see at a glance.

Where the Calendars Actually Overlap

Lay the two calendars on top of each other and the overlap is not evenly distributed. A Gulf Coast market can be inside hurricane season, June through November, while also sitting near the tail end of a hail season that started as early as February, meaning parts of the year carry genuine dual exposure. A northern Plains market, by contrast, sees its hail peak in July, squarely inside hurricane season’s calendar window even though hurricanes themselves rarely reach that far inland, meaning the overlap there is a coincidence of dates rather than a shared physical risk.

State Farm alone paid over $5.6 billion in hail-related claims in 2025, with Texas leading at $1.4 billion, a state that also sits inside the Atlantic hurricane season’s geographic footprint. A market like that is not choosing between a hail story and a hurricane story. It is living inside both calendars for a meaningful stretch of the year.

Turning the Overlap Into a Staffing and Spend Plan

A single national storm-season plan misses this entirely. A roofing company operating across regions needs a calendar built region by region, not a single company-wide readiness date, because the Texas Gulf Coast, the Texas Panhandle, Colorado, and the northern Plains are not on the same clock even though they are all nominally in hail territory. The same logic applies to a hurricane-exposed market layering its own fixed June-through-November window on top of whatever hail risk it separately carries.

Getting the calendar right region by region is a staffing and marketing-spend decision, not just a trivia question, and it is the difference between a canvassing or appointment-setting budget that is ready before a season opens and one that is still ramping up after the window has already started.
