Washington, D.C. experiences an average of 15 to 20 freeze-thaw cycles per winter. Daytime temperatures climb into the upper 30s or low 40s, melting snow on rooftops. Nighttime temperatures drop into the teens, refreezing meltwater at the eaves. This cycle repeats daily during prolonged cold snaps. The result is thick ice dams that grow larger with each thaw. Historic homes built before 1950 often lack vapor barriers, ridge vents, or adequate attic insulation. Heat escapes through the roof deck, melting snow from below. The meltwater has nowhere to go. Ice dam steaming services become essential when the freeze-thaw pattern persists for more than three days.
