What snow load must a Jackson roof carry?

Teton County’s published design criteria set ground snow loads of 120 psf in the tan GIS zones and 175 psf in the blue zones, far beyond the roughly 30 psf values the plains-town offices covered on this site publish. Which zone your parcel sits in comes from the county GIS mapping, and structural design flows from that number before any panel choice.

Why is standing seam the default roof in Jackson Hole?

Because the load case rewards it. A concealed-fastener standing seam surface sheds snow, keeps its seams above meltwater, and lets panels move through hard freeze-thaw cycles while the clips stay anchored against 115 mph design wind. Snow retention over entries and walkways gets engineered into the same system. The valley’s architectural look grew out of that physics as much as out of taste.

What is a WUI permit and do I need one?

Teton County requires a wildland-urban interface permit from Jackson Hole Fire/EMS before a building permit application can even be submitted, per the county Building Division. It addresses wildfire exposure, an extra step the plains towns skip. A bidder fluent in the WUI step and the county portal has worked the valley before; one who is surprised by it has not.

Teton County metal roofing

Metal roofing in Jackson: snow country first, wind country second

Every other Wyoming market on this site starts with wind. Jackson starts with snow. Teton County's published design criteria set ground snow loads of 120 psf in the valley's tan GIS zones and 175 psf in the blue zones, with a 115 mph basic wind speed, Seismic Design Category D, and a 34 inch frost depth. The plains towns design to a fraction of that snow number. A roof in Jackson or unincorporated Teton County is a structural project with an architectural finish, which changes who should build it, what it costs, and how the valley looks.

This page treats Jackson on its own terms: the load case, the standing seam vernacular that answers it, and the town-county licensing system. The statewide fundamentals, uplift ratings, the no-license verification, the storm-contract law, live in the Wyoming metal roofing guide and still apply here.

Built for the load, then for the look

Design in the valley runs structure first. A 175 psf ground snow load is a different engineering problem from a plains reroof: rafters, bearing, and deck get checked before panels get picked, and roof geometry, where snow slides and stacks, is a safety decision. Wind does not go away either; the county's 115 mph basic wind speed means the uplift details on wind-rated roof systems still govern clip and fastening choices, layered on top of the snow work.

That load case is why architectural standing seam owns Jackson Hole. A smooth concealed-fastener surface sheds snow instead of snagging it, raised seams keep the locks above meltwater through the freeze-thaw season, and clips let long panels move without opening a fastener hole. Snow retention over entries and walkways gets engineered into the same system rather than bolted on afterward. The matte standing seam that defines valley construction is the structural answer wearing good clothes; the system itself is covered on standing seam metal roofing.

One license system for town and county

Jackson runs a licensing arrangement no other city program on this site shares: contractor licenses issued by the Town of Jackson are valid in both the town and unincorporated Teton County, through a Certificate of Qualification card for the master of record, then the license. One call confirms a roofer for any address in the valley. Permits run through the Teton County Building Division's online portal, and the county requires a wildland-urban interface permit from Jackson Hole Fire/EMS before a building permit application can be submitted.

Remember what none of that checks: Wyoming still has no statewide roofer license, and the town license tests paperwork, not snow-load engineering. The verification below is what closes the gap, here as everywhere.

Budgeting a resort-market roof

Jackson pricing resists the tidy figure. No valley-specific published cost met this site's sourcing bar, and a market of custom homes and short build seasons would strain any average. The honest frame: take a national manufacturer-published range like Western States Metal Roofing's $10 to $16 per square foot installed for standing seam as a budgeting floor, then expect snow-zone engineering, snow retention, custom detailing, and valley logistics to price a Teton County project above it. A strong bid itemizes those layers; metal roof installation explains what each is doing.
