Casper’s high plains winters bring repeated freeze-thaw cycles that force water under shingles along eaves, especially on homes built before 1980 in East Casper and Mills. Ice dams form when attic heat melts snow on the upper roof while the overhang stays below freezing, backing water into living spaces. We start every job by clearing the dam mechanically, then trace the moisture path with infrared to find hidden saturation in sheathing and insulation.
Many single-story ranch houses in West Casper and Evansville have shallow roof pitches and limited soffit venting, which traps heat and accelerates dam formation once temperatures drop below 20 degrees. We add targeted baffles and ridge vents where code allows without cutting new openings that could void existing warranties. On steeper sections near Casper Mountain, we also check for ice jacking that loosens fasteners on older asphalt shingles.
After the dam is removed we replace any delaminated felt or plywood, then seal the lower courses with self-adhered membrane rated for 200 mph wind-driven rain. Homeowners in Downtown Casper often see recurring leaks because previous repairs used only caulk; we install continuous step flashing and new drip edge instead. All work is done from the roof so we can inspect the entire eave run in one pass.
Technician insight
In Casper the thing that catches most people out with ice dam roof repair is how quickly wind packs snow into the eaves on the north side of houses in West Casper and near the river; those spots stay shaded and refreeze even after the rest of the roof clears, so you have to treat the full eave run or the dam just reforms the next cold snap.
Recurring leak after two prior fixes
Homeowner in Downtown Casper reported water stains above the kitchen after a January thaw. We found the dam had pushed under the original felt on a 1970s ranch with shallow pitch. We removed the ice, replaced eight feet of sheathing and felt with new membrane, and added ridge venting. No further leaks through the remaining winter.
