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.
The St. Louis Dispatch Process, Step by Step
Crews walk the eaves, valleys and gutter line first and photograph every dam and every point where water is tracking inside, before touching anything. You get shown what they found and quoted the crew-hour rate before work starts.
Then the ice comes off with low-pressure steam, starting wherever water is actively backing up so drainage opens early. Frozen gutters and downspouts are cleared in the same visit, because a cleared eave above a solid block of ice in the gutter dams again on the next cold night.
Why the gutter has to be cleared in the same visit
A dam sitting above a gutter packed solid with ice is only half the problem. Clear the eave and leave the trough frozen, and the next day's meltwater has nowhere to run — it backs up onto the roof and the dam rebuilds from the bottom.
Crews steam the trough and the downspout through to daylight on the same visit. It adds time, which is why the hour estimate given on the phone accounts for it, and it is the difference between a fix and a repeat visit in St. Louis the following week.
Why salt and ice melt make it worse
Calcium chloride opens a narrow channel and leaves the dam standing. The channel refreezes, the dam does not go anywhere, and in the meantime the runoff corrodes gutter seams, fasteners, flashing and anything growing underneath.
It is a stopgap at best. On a roof in St. Louis with an active leak it buys hours, not days, and it adds a corrosion problem to the water problem.
What happens after the ice is off
Once the eave is clear and water is draining, the crew walks the interior with you where there is visible damage and says plainly whether it needs drying. Wet insulation and a damp ceiling cavity do not resolve themselves in a cold St. Louis February.
If it does, that is a separate scope and it gets written separately — nobody is upsold a dryout on the strength of one damp patch.

Neighborhoods and Towns We Reach From St. Louis
Crews working St. Louis cover the adjoining communities on the same route — Saint Louis, Saint Ann, Maryland Heights, Bridgeton and Hazelwood — so a storm week usually means one truck handling several addresses in Saint Louis County rather than separate trips.
Nearest hub towns with their own crew pages: University City, Kirkwood, Florissant, Ballwin, St. Charles, Chesterfield.
Crews cover St. Louis and the surrounding Saint Louis County towns through the whole season, and during a freeze event they run from first light until dark.
