Most St. Louis homeowners find out about an ice dam from the inside — a damp patch on a bedroom ceiling, or water tracking down the inside of a window frame. As part of our complete St. Louis winter roof services, crews handle ice dam removal across Saint Louis County.
The Saint Louis County Trap: Modest Snow, Constant Cycling
What catches people out in Saint Louis County is that the snow looks harmless. Two or three inches reads as nothing, and it builds ice on an eave just as effectively as a northern storm given enough cycles.
The expectation is the problem. Nobody in St. Louis re-roofs with ice dams in mind, so when a cycling stretch arrives the houses with the least margin all leak in the same week.
Ice-barrier practice in Saint Louis County
The residential code Missouri follows requires eave ice barrier on new work, and Saint Louis County enforces it. The variable on any given house is simply when it was last roofed.
Ice Dam Removal in St. Louis: How The Work Runs
Dormers, valleys and dead spots
Ice does not distribute evenly. It concentrates where two roof planes meet, behind dormers, in dead valleys that drain nowhere, and along the north face that never sees sun. Those pockets hold water deepest and leak first. Water Stain on the Ceiling in Winter.
A crew working a roof in St. Louis clears the full eave line and then goes back through the valleys and dormer pockets specifically, because clearing the easy straight run and calling it done is how a roof leaks again a week later.
Why the dam formed in the first place
Ice dams are a heat problem wearing a weather costume. Warm air escaping into the attic melts snow on the upper roof; that meltwater runs to the eave, which hangs past the heated envelope and stays below freezing; it refreezes there, and the ridge of ice grows a layer every cycle. Removal is the emergency fix. Before the crew leaves you will know which part of your attic is feeding it.
Working at night and during an active storm
Freeze events do not keep office hours, and the worst leaks tend to announce themselves in the evening when the day's melt refreezes. Crews run lit, and a roof that is actively collecting snow is worked anyway, because waiting for better weather means the dam is bigger when somebody finally gets to it.
What does stop a crew is wind and lightning. Both are judgment calls made on site in St. Louis, and a postponed start gets explained rather than dressed up.
What steam actually does
A steam unit delivers water at roughly 290°F at a pressure low enough to rest your hand in the plume. It cuts a channel straight through the ice and lifts the dam off in sections, right down to the shingle. The heat does the work, not force, so granules, seal strips and flashing come through untouched.
That is the whole difference between steam and the hot pressure washers often sold as steam. A pressure washer cuts ice fast because of its pressure — and that same pressure strips the granules off asphalt shingles and drives water up under the courses. One method removes ice. The other removes ice and roof.
What the crew does on arrival
Before anything is touched, the crew walks the eaves, valleys and gutter line and photographs every dam and every point where water is tracking inside. You get shown what they found. Then the dam comes off in sections, starting wherever water is actively backing up, so drainage opens early rather than at the end.
Downspouts and gutter troughs get cleared in the same visit where they are frozen, because a dam removed above a solid block of ice in the gutter just reforms in the next cold night.

Scheduling for St. Louis tightens up during a freeze event, which is exactly when the phone beats the form. Water coming in means a call, not an email.
Most jobs do not stop at one service. Ice Dam Removal in St. Louis often runs alongside water mitigation & dryout in St. Louis, and both get written into one scope rather than billed as separate visits.
