Wyoming homeowner guide
From move-in basics to emergency response: everything a Wyoming homeowner needs to know, specific to this state's climate, hazards, and conditions.
1 Basic ownership
Wyoming homeownership means managing extreme and persistent wind (Cheyenne averages 12 mph, the second windiest US city), severe blizzards, wildfire in the mountains, high radon, and a very high UV index at Wyoming's average 6,000-foot elevation. Rural isolation amplifies every system failure.
Critical systems to locate
-
Main water shutoff and well system
Most Wyoming homes outside of Cheyenne and Casper are on private wells. Know the well head, pressure tank, and pump circuit shutoff at the electrical panel. Power outages mean no water. Stock 7 days of water in jugs before winter.
-
Heating system and fuel
Wyoming homes use natural gas (urban), propane (rural), and coal in some communities. Know your fuel type and keep reserves above 30% of tank capacity. Wyoming blizzards can delay delivery 24-72 hours in rural areas.
-
Radon: test immediately
Wyoming has high radon statewide, with very high levels in some counties (Niobrara, Albany, Carbon). Test within 90 days of move-in. EPA rates 21 of Wyoming's 23 counties Zone 1, the highest potential.
Monthly priorities
-
Wind damage inspection
Wyoming's constant wind causes shingle lifting, siding damage, and vent cap failure. Inspect the exterior monthly for wind-lifted shingles, damaged fascia, and unseated vent caps. Loose shingles in Wyoming last one wind event before they're gone.
-
UV and dry air maintenance
Wyoming's high-altitude UV index (35-40% higher than sea level) accelerates paint, caulk, and roofing deterioration. Check all exterior caulking and painted surfaces annually. Low humidity (10-20%) causes wood to dry and split.
2 Seasonal maintenance
Wyoming's seasons: spring flooding from snowmelt, summer wildfire and thunderstorms, fall blizzard preparation, and long, harsh winters.
Spring (March to May): snowmelt and wind season
-
Wind season post-inspection
Spring brings Wyoming's strongest winds. Inspect the entire exterior after spring wind events: roof, siding, soffits, gutters. Replace any lifted shingles immediately; Wyoming's next wind event will pull them off entirely.
-
Well system spring inspection
Test well water after spring thaw. Wyoming's geology (uranium-rich soils) and agricultural activity can affect well water quality. Annual testing for coliform, nitrates, and arsenic is recommended.
Summer (June to September): wildfire season
-
Wildfire defensible space
Wyoming mountains and foothills (particularly the Bighorns, Wind Rivers, and Laramie Mountains) have significant wildfire risk. Maintain 30-foot defensible space, use fire-resistant landscaping, and screen vents with metal mesh. Know your evacuation route.
Fall (September to October): blizzard preparation
-
Comprehensive blizzard prep by October 1
Wyoming blizzards can arrive in September. By October 1: heating system serviced, propane tank full, pipes insulated, 7-10 day supplies stocked, snow blower serviced, and vehicle winter kit assembled.
3 Preventive protection
Wyoming's critical preventive priorities: radon mitigation, wind-resistant roofing, and wildfire defensible space.
Radon mitigation
-
Test and mitigate
Wyoming's very high radon risk demands immediate testing at move-in. Sub-slab depressurization systems work well in Wyoming's geology. NRPP-certified mitigators available.
Official sources
Wind-resistant roofing
-
Impact-resistant, wind-rated shingles
Standard 3-tab asphalt shingles fail in Wyoming's wind. Use architectural shingles rated for 110-130 mph wind resistance, or metal roofing. Many Wyoming insurers offer premium discounts for Class 4 / wind-rated roofing.
4 Weather preparedness
Wyoming's primary threats are blizzards, extreme wind, wildfire, and hail. The state's low population density means emergency services are far away; self-reliance is essential.
Blizzard preparedness
-
Wyoming blizzards close I-80 and I-25
The Cheyenne to Laramie corridor (I-80) is one of the most frequently closed highways in the US due to wind and snow. Never drive in a Wyoming blizzard warning. Stock 7-10 days of supplies. Black Hills Energy: 1-888-890-5554. Rocky Mountain Power: 1-888-221-7070.
5 Emergency response
Wyoming emergency scenarios: blizzard, wildfire evacuation, pipe freeze, and the isolation that makes every response take longer.
Wildfire evacuation
-
Leave immediately on evacuation order
Wyoming wildfires spread extremely fast in dry, windy conditions. Leave when ordered. Do not wait to assess. Take medications, documents, pets. Use your pre-planned route.
Burst pipe
-
Shut off well pump and main shutoff
Turn off well pump circuit at breaker. Close main house shutoff. Open all faucets. Wyoming rural plumber wait times after freeze events: 48-96+ hours.
Basement flooding
-
Snowmelt and groundwater flooding
Do not enter flooded spaces if electrical equipment is submerged. Call Rocky Mountain Power (1-888-221-7070) or Black Hills Energy (1-888-890-5554) to disconnect at the meter. Pump out, dry immediately.
Power outage
-
Wyoming blizzard outages in remote areas
Rural Wyoming outages can last 48-96 hours. Rocky Mountain Power: 1-888-221-7070. Black Hills Energy: 1-888-890-5554. Generator outside only, clear of snow, 20+ feet from windows.
Gas leak
-
Propane response
Propane smell: everyone out immediately. Propane sinks to low areas. Exit quickly. Call 911 from outside. Call propane supplier. Do not re-enter until cleared.
House fire: get out fast with winter gear
-
Two exits, winter gear accessible, never re-enter
Wyoming fire escape in winter means exiting into potentially -30°F temperatures with wind chill. Keep coats and boots accessible near bedroom doors. Two exits from every room. Outdoor meeting place. Crawl under smoke. Call 911. Never re-enter. Wyoming EMS in rural areas may be 20-40+ minutes.
