Sioux Falls experiences repeated freeze-thaw cycles under its humid continental climate, especially on roofs in McKennan Park and Augustana where older homes often lack modern ridge venting. Ice dams form when heat escaping from the attic melts snow on the upper roof, then refreezes at the eaves, backing water under shingles. We see this most on homes built before the 1980s in Terrace Park and All Saints, where original felt underlayment has dried out and no longer seals nail penetrations.
Removal starts with infrared scanning to locate trapped moisture without tearing off good shingles. Once the dam is cleared, we check for hidden rot along the drip edge and replace damaged underlayment with self-adhering membrane rated for -20°F. In West Sioux and South Sioux Falls, where wind-driven snow is common, we also inspect step flashing around chimneys that frequently gets lifted during the same storms that create the dams.
Homeowners sometimes try heat cables or roof rakes, but these rarely reach the ice wedged behind gutters on two-story homes near Falls Park. We carry portable steam wands that melt ice from the top down without cracking asphalt shingles. Every job includes a written report noting any code issues with attic ventilation that Minnehaha County inspectors look for during re-roof permits.
Technician insight
In Sioux Falls the thing that catches most people out with Ice Dam Roof Repair is how homes in McKennan Park with original knob-and-tube wiring and minimal insulation create constant heat pockets right under the roof deck during our long cold snaps.
McKennan Park Two-Story Ice Backup
Water stains appeared on second-floor ceilings after a January thaw. We found a three-foot ice dam behind the north gutter on a 1928 home with original felt underlayment. Steam removal and new ice-and-water shield along the eaves stopped the leaks; the owner added soffit vents the following spring.
