How Strong Does Wind Have to Be to Damage a Roof in Omaha?

Every year. From 2016 through 2025, the NOAA Storm Events Database lists 211 thunderstorm wind reports in Douglas and Sarpy counties, on 67 different days, or six to seven days a year on average. Every one of them is 50 knots (about 58 mph) or stronger, the National Weather Service's line for a severe thunderstorm. The quietest year, 2019, still had 9 reports on 3 days. The busiest, 2021, had 37.

June leads by a wide margin, and May through July account for 151 of the 211 reports, or 72 percent. Winter is not always safe: on December 15, 2021, nine severe wind reports came in from the two counties in a single day.

A few storms produce many of the reports. June 16, 2017 had 18, July 12, 2023 had 13, May 24, 2024 had 12, and May 16, 2017 had 10. Like hail, wind damage can be heavy in one part of the metro and light a few miles away.

The National Weather Service defines a severe thunderstorm as one with winds of at least 58 mph (50 knots), hail at least 1 inch across, or a tornado, and its glossary notes that structural wind damage may imply a severe thunderstorm. That makes 58 mph the practical line for when to look at your roof after a storm.

Omaha storms often go well past it. Of the 211 reports from 2016 through 2025:

• 43 were 65 knots (about 75 mph) or stronger
• 26 were 70 knots (about 81 mph) or stronger
• The strongest was a measured gust of 90 knots (about 104 mph) in Omaha on June 16, 2017
• Gusts of 87 knots (about 100 mph) were estimated on three days: June 25, 2024 at the National Weather Service office near Valley, July 31, 2024 at Gretna and Waterloo, and August 9, 2025 at Waterloo
• Gusts of 83 knots (about 96 mph) were measured near Clearidge on August 23, 2016 and at Eppley Airfield on July 9, 2021

For comparison, the Enhanced Fujita scale the Storm Prediction Center uses for tornadoes starts at EF0, for estimated 3 second gusts of 65 to 85 mph. Those are estimates made from the damage, not measurements. The same ten years had 11 tornado reports in Douglas and Sarpy counties, all in April, May and June, so in the metro straight line thunderstorm wind is the far more common cause of wind damage.

Wind does not hit a roof evenly. IIBEC, a building enclosure consultants' association, notes that damage is most likely where the roof meets the strongest wind forces: the eaves, hips and ridges.

Shingle wind ratings come from two ASTM laboratory tests, and the manufacturer lists them on the product's specifications. Owens Corning explains the classes this way.

ASTM D3161, the fan-induced method:

• Class A: "shingles that passed testing at 60 mph"
• Class D: "shingles that passed testing at 90 mph"
• Class F: "shingles that passed testing at 110 mph"

ASTM D7158, the uplift force method:

• Class D: "resist uplift at wind speeds up to 90 mph"
• Class G: "resist uplift at wind speeds up to 120 mph"
• Class H: "resist uplift at wind speeds up to 150 mph"

Owens Corning also notes that "Asphalt roofing shingles in the market generally all carry the same wind resistance classifications: ASTM D3161 Class F and ASTM D7158 Class H. However, warranted wind coverage varies by individual product." Malarkey's Vista shingle, for example, lists ASTM D3161 Class F and ASTM D7158 Class H, a 110 mph standard wind warranty and a 130 mph enhanced wind warranty.

A rating describes new shingles tested under controlled conditions. On a real roof, how the shingles were installed, how old they are and whether earlier storms already loosened or creased them decide how they hold up. Owens Corning points out that the installation guide and warranty spell out how shingles must be installed to get the warranted wind coverage. If you are replacing a roof after storm damage, see the best roof for hail in Omaha for how impact rated shingles compare.

Wind damage shows up as shingles that are missing, creased, folded or torn, most often along the edges, hips and ridge of the roof. IIBEC reports that a sealed shingle hit hard enough by wind leaves lasting evidence: creases, folds, tears, or missing shingles or pieces of them. A shingle that is only unsealed, with none of those marks, is not by itself evidence of wind damage.

From the ground and from windows, look for:

• Missing shingles or tabs, or patches that look a different color than the rest of the roof
• A straight crease line across a shingle where it bent up and back
• Lifted tabs or exposed nail heads along the edges and ridge
• Missing or loose ridge cap shingles
• Flashing pulled away around a chimney, wall or vent
• Granules or shingle pieces in the gutters, at the downspouts or in the yard
• Limbs or other debris on the roof, which can puncture or scrape shingles
• New water stains on ceilings or damp insulation in the attic

Stay off the roof. Wind damaged shingles can come loose underfoot, and a professional inspection will see more than you can safely see. Our guide on how to tell if your roof has hail damage covers the hail half of the same storms, since one storm often brings both. If water is already coming in, see what to do about a leaking roof in Omaha.

Document the damage, prevent more of it, and report it to your insurer. The Nebraska Department of Insurance's After the Storm guidance says to report damages as soon as possible, to make only temporary repairs to prevent additional losses, and not to make permanent repairs until an adjuster inspects the damage.

In practice:

• Take photos and video from the ground: the roof, shingles in the yard, the gutters, and any water stains inside, with the date noted
• Protect what is open: if shingles are missing and rain is coming, a temporary tarp limits further damage. Keep the receipts
• Call your insurer or agent: report the storm date and keep a log of who you spoke with and when
• Get an inspection: Rocket Roofing General Contractor offers hail and wind damage roof repair with a free inspection

The claim itself, from the adjuster's visit to deductibles, is covered in our Nebraska roof insurance claims guide. It is general information, not legal advice. Wind and hail share a season, and our guide to when hail season is in Omaha shows the months both are most likely.

Rocket Roofing General Contractor downloaded the NOAA National Centers for Environmental Information Storm Events detail files for 2016 through 2025 and kept every Thunderstorm Wind event logged for Douglas County and Sarpy County, Nebraska: 211 reports on 67 days, from April 27, 2016 to September 14, 2025. A day with reports is a calendar date with at least one report in either county. Speeds are converted from knots to miles per hour and rounded.

Of the 211 reports, 77 are measured gusts and 134 are estimated gusts. An estimated gust is the observer's judgment from the damage they saw, not an instrument reading. Storm Events lists reports, not every gust that blew, and reports cluster near roads, towns and airports where someone can see the damage and send it in, so a missing report does not mean a storm missed your house. Data was pulled on November 3, 2026; NOAA may add or revise reports later.

Anyone can check these numbers in the NOAA Storm Events Database by choosing Nebraska, then Douglas or Sarpy County, and Thunderstorm Wind as the event type.
