This directory holds eight roofing listings for Mason City, Iowa. None of them has a Google rating matched to it yet, so what follows is contact detail rather than reputation data.
All of them are recorded in Cerro Gordo County. Roofing permits and inspections are issued locally rather than by the state, so a re-roof in Mason City goes through Cerro Gordo County or the municipality's own building department, whichever holds jurisdiction at the property.

Licensing for roofers working in Mason City
Iowa does not license roofing contractors. It requires them to register with the Iowa Department of Inspections, Appeals, and Licensing, and that requirement covers work in Mason City.
Registration and licensure are not the same thing — a registration number records that a business completed a filing, and it sits alongside, not instead of, a permit and an inspection through Cerro Gordo County or the city.
Source: Iowa Department of Inspections, Appeals, and Licensing. Checked August 2026. Licensing rules change — verify before you sign anything.

* The most recent data year is partial. NOAA publishes storm reports on a rolling basis and the final months are still being processed, so a low count in the last year is not evidence of a quiet year. The curated archive behind these counts runs through May 31, 2026; anything later sits in the preliminary block below.
Notable events in the archive
- May 21, 2024 -- Thunderstorm Wind (61 kt gust) -- $150K property damage reported
- Apr 12, 2022 -- Tornado (EF1) -- $125K property damage reported
- Dec 15, 2021 -- Thunderstorm Wind (72 kt gust)
- Dec 15, 2021 -- Tornado (EF2) -- $100K property damage reported
- Aug 24, 2018 -- Hail (Golf Ball hail, 1.75 in) -- $5K property damage reported
Selected by the dataset’s own rule rather than by editorial choice: the largest hail, the peak wind gust, the strongest tornado and the two costliest events by recorded property damage, deduplicated and newest first. Any dollar figure above is NOAA’s recorded estimate for that one event.
Preliminary — not yet in the permanent archive
4 preliminary storm reports have been filed for Cerro Gordo County since June 1, 2026: 2 thunderstorm wind events, 1 hail report and 1 tornado. The largest hail in the window is 1.00 in (Quarter - Half Dollar), reported August 7, 2026. The strongest gust reported is 72 kt (about 83 mph), on July 2, 2026.
Preliminary reports covering 2026-05-31 onward come from National Weather Service storm reports filed as events occur. They have not yet been through the quality-control review that produces the permanent archive, and individual reports may later be revised, combined or withdrawn. NOAA Storm Prediction Center storm reports.
What these counts cover. County figures count events NOAA recorded against a county (hail, thunderstorm wind and tornadoes). High wind, winter storms, ice storms, blizzards, heavy snow, hurricanes and tropical storms are recorded against National Weather Service forecast zones rather than counties, so they are reported at state level instead. Counts reflect events that were observed and reported.
“Significant” on this page means an event meeting any one of three tests: hail 1.00 in across or larger, a wind gust of 58 kt or more (the National Weather Service severe thunderstorm criterion), or any tornado. It is a severity definition used by this dataset and is not an official NOAA classification.
The damage figure. $937,000 is the sum of NOAA’s recorded property-damage estimates across every event in Cerro Gordo County over the period — a county total, not a figure for any one property, any one building or any one claim. NOAA records these figures as estimates made at the time of reporting. They are not adjusted for inflation, and they are frequently absent or zero — a zero means nothing was recorded, not that nothing was damaged.
Source. Archived figures come from the NOAA National Centers for Environmental Information Storm Events Database, covering 2016 through May 31, 2026. Anything after that date comes from NOAA Storm Prediction Center preliminary storm reports and is labelled preliminary wherever it appears. Both are US Government works in the public domain.
