Code of record figure per the City of Gillette's adopted 2018 IBC building code, one of the better sourced snow load values in this set.
No Gillette-specific figure was located on a city ordinance page. Regional Wyoming Risk Category II basic design wind speeds run about 105 mph in the west to 115 mph or higher on the eastern plains, and structural engineering in Campbell County is described as dominated by wind and soil considerations given expansive clay soils. 110 mph is used here as a midpoint approximation, not a confirmed Gillette figure.
With the lowest snow load of the five cities at 25 psf, but wind and expansive clay soils flagged as the dominant structural drivers locally, roof to wall attachment and perimeter and corner fastening density matter more here than snow drift design. The highest precipitation total of the five cities at 17.59 inches per year also elevates the importance of drainage design and membrane seam integrity. Verify current code values with the Gillette building department before specifying a system.
Campbell County ranks among Wyoming's top three counties for tornado occurrence between 1950 and 2003, along with Laramie and Goshen counties. A Campbell County F2 tornado destroyed a mobile home park in the community of Wright, killing two people and destroying about 40 homes.
Powder River Basin coal mine support infrastructure, a regional medical center, retail, and energy services buildings in the most energy-productive coal region in the United States.
Gillette's commercial base is anchored by Interstate 90 and rail served industrial development northeast of downtown at Fort Union Industrial Park, with additional industrial growth planned near the regional airport, reflecting the city's long standing role as a coal and energy sector hub in the Powder River Basin.
- 01
Gillette sits in the Powder River Basin, the largest coal-producing region in the United States, with energy infrastructure buildings that require roofing systems rated for the region's extreme wind exposure
- 02
A 105 mph design wind at Exposure C, with no sheltering terrain, means uplift resistance rather than snow load is the governing case for roof systems here
- 03
Coal mine support buildings and energy service facilities in the Gillette area include structures with large unobstructed roof areas where wind-driven uplift forces are the dominant design load

Gillette roofing facts
- 01Why does freeze-thaw matter for commercial roofs in Gillette?
- Because Gillette, WY runs through an estimated 80 freeze-thaw cycles a year. Water that gets into a seam freezes, expands, and opens the seam further with every cycle, so the roof system has to be watertight as one surface.
- 02How much wind does a Gillette commercial roof have to be built for?
- Design to 110 mph at Exposure C under ASCE 7, then verify with the Gillette building department. Uplift resistance at edges and corners is what that figure drives on a low-slope roof.
- 03How much snow does a Gillette commercial roof carry in a typical winter?
- Gillette averages roughly 35 inches of snowfall a year. Drifting against parapets and rooftop units concentrates that load, so drainage paths and drift zones are checked in every assessment.
- 04If my Gillette roof is leaking, how quickly will A-1 get back to me?
- Within 24 business hours. Report an active leak through the contact page or by phone and it moves to the front of the Gillette, WY schedule.
- 05Which structural loads govern a commercial roof in Gillette?
- Two numbers: 25 psf ground snow load (Code of record figure per the City of Gillette's adopted 2018 IBC building code, one of the better sourced snow load values in this set.) and 110 mph design wind at Exposure C (No Gillette-specific figure was located on a city ordinance page. Regional Wyoming Risk Category II basic design wind speeds run about 105 mph in the west to 115 mph or higher on the eastern plains, and structural engineering in Campbell County is described as dominated by wind and soil considerations given expansive clay soils. 110 mph is used here as a midpoint approximation, not a confirmed Gillette figure.). With the lowest snow load of the five cities at 25 psf, but wind and expansive clay soils flagged as the dominant structural drivers locally, roof to wall attachment and perimeter and corner fastening density matter more here than snow drift design. The highest precipitation total of the five cities at 17.59 inches per year also elevates the importance of drainage design and membrane seam integrity. Verify current figures locally before specifying.
- 06What is the working window for a roof project in Gillette?
- About 144 days, May 21 to Sep 25 in a typical year. Repairs run year-round; full coating and spray foam applications are scheduled inside that window because cure times stretch in the cold.
