Wyoming roofs do not leak the same way a rainy-coast roof does. An ice dam is a ridge of ice at the eave. Meltwater from the upper roof has nowhere to go, so it backs up under shingles or metal panels and into the attic. From the street it can look like a pretty winter house. Inside, you get wet insulation, stained drywall, and a claim that starts as "we thought it was just ice."
Restoration Wranglers is based in Sublette County. We handle water damage in mountain homes where freeze-thaw is the season, not a surprise. This is how ice dams actually put water in the house, and what to do before it becomes a mold job.
Why ice dams happen here
Heat leaking into a cold attic melts snow on the upper roof. That water runs down to the cold overhang, where it freezes again. The dam gets taller. The next melt has to go somewhere, and "somewhere" is under the roof covering.
Tight envelopes, vaulted ceilings, and bath fans that dump into the attic all make it worse. So does a long stretch of subzero nights after a wet snow. We already wrote about what a leaking roof does to an attic and snowmelt around the foundation. Ice dams are the winter version that starts at the eave, not at the ground.
You will usually notice it as:
- Thick ice or a gutter full of ice along one elevation
- Water stains on the ceiling just inside an exterior wall
- Damp or compressed insulation at the eaves
- Peeling paint or bubbling drywall near a vaulted ceiling
- A drip that shows up on a sunny afternoon after a cold night, then "goes away"
That drip did not go away. It soaked into wood.
What to do in the first day
Do not climb a frozen roof with a hatchet. That is how people fall, and how shingles get ruined.
From the ground, photograph the ice line and any interior stains. If water is actively coming in, catch it and pull soaked contents off the floor. Call for extraction and drying the same day, not "when it warms up." We have a separate first 24 hours checklist. Ice-dam water is still clean water until it sits in insulation and drywall long enough to become a mold problem.
If you can safely reach the attic, look at the eave bays. Do not start ripping insulation until someone has measured moisture. "It looks dry" is how ice-dam claims stall. We wrote about how to document a Wyoming water loss for that reason.
Repair vs wait for spring
Waiting until May is how a small eave leak becomes black insulation and a ceiling that has to come down. Drying can start in winter. Heat, air movement, and dehumidification still work in a closed-up Sublette County house. The roof covering can wait for a safe day. The wet assembly cannot.
Ice cables and roof rakes are prevention tools. They are not a drying plan. If water already made it inside, the job is moisture mapping, extraction, and dry-out, then a conversation about ventilation and insulation so it does not repeat next January.
Call while it is still a drip
If you have ice at the eaves and water on a ceiling in Pinedale, Big Piney, or anywhere in Sublette County, call Restoration Wranglers at 307-323-7777. We are IICRC certified, licensed, and insured. We work 7 a.m. to 7 p.m. We will tell you if it is a roofing issue, a wet attic, or both, and we will document it so the claim matches the house.

Most systems use a condensate drain line to carry that water safely outside your home. On a hot, humid day, a central air system can produce several gallons of water. When everything works right, you never see it. When something goes wrong, that water ends up where it shouldn't.
