Homeowners across Saint Louis County call about icicles. Icicles are cosmetic. The dam behind them, holding back standing water, is not. As part of our complete St. Louis winter roof services, crews handle commercial roof snow 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.
Commercial Roof Snow Removal in St. Louis: How The Work Runs
Mid-span is where the margin runs out
Long-span steel and open-web joist roofs carry least where the drift is deepest. The average depth across the field is not the number that matters; the depth over the longest unsupported span is. Ceiling Sagging or Bulging After Snow.
That is where crews measure on a St. Louis building, and it is why two roofs with the same snowfall can be in very different trouble.
Drains and overflows come first
Before anything else comes off, the drains, scuppers and overflow outlets get opened. Otherwise the melt from the clearing has nowhere to go and the roof trades a snow problem for a ponding one.
On a deck in St. Louis with internal drains that means confirming flow below, not just clearing the grate.
Reading the design load off the drawings
Where structural drawings exist they state the design ground snow load and the roof's own capacity, and that number turns the whole question from opinion into arithmetic. Measured depth and density against design capacity gives a percentage rather than an argument.
Where the drawings have been lost - common on older St. Louis stock - the conservative assumption is the code minimum of the era the building went up, which is usually well below what a modern roof would be built to.
Why large decks carry the most risk
A long-span steel or open-web joist roof has the least margin exactly where the drift is deepest — mid-span. Snow does not settle evenly either: it piles against parapets, behind rooftop units, in the lee of higher adjoining roofs, and in valleys between bays. The average depth across the roof is not the number that matters.
Crews survey depth and density at the drift points rather than the middle of the field, and calculate the working load from that against the structure's design capacity.
Storm routes for a portfolio
Properties on a standing contract get cleared on a scheduled route after each qualifying snowfall, in a priority order agreed in advance by risk rather than by who calls first.
For anyone managing several St. Louis buildings that is the difference between a plan and a scramble.

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 commercial snow pages: University City, Kirkwood, Florissant, Ballwin, St. Charles, Chesterfield.
Coverage runs across St. Louis and the nearby towns all winter, and capacity is surged into whichever Missouri market the storm actually hits.
Most jobs do not stop at one service. Commercial Snow in St. Louis often runs alongside crane-assisted snow removal in St. Louis, and both get written into one scope rather than billed as separate visits.
