Every Florissant winter produces the same two calls: the ones who see the ice early, and the ones who see the ceiling stain first. As part of our complete Florissant winter roof services, crews handle commercial ice dam removal across Saint Louis County.
Why Florissant Roofs Dam Up: Cycling, Not Snowfall Totals
An ice dam needs meltwater and a cold eave, and Florissant supplies both on an ordinary week. A thin cover that melts by lunchtime and sets again after dark is a perfectly good dam factory.

And the cycling is relentless rather than dramatic. Fifteen or twenty crossings of freezing in a season each add a layer, and the houses with the thinnest attic insulation in Saint Louis County all find out in the same week.
Ice-barrier practice in Saint Louis County
Because ice is not the first thing a homeowner in Florissant thinks about, the eave membrane is the detail most often value-engineered out of a re-roof quote. It is worth asking for by name.
Commercial Ice Dam Removal in Florissant: How The Work Runs
Flat roofs fail differently
A pitched residential roof dams at the eave. A commercial deck dams at its drainage: frozen scuppers, iced-over internal drains, and ponding that refreezes into a sheet across the low spots. Water then sits on the membrane at depth, finds a seam or a flashing detail, and comes through into the tenant space below.
Parapet walls make it worse by holding the melt on the deck instead of letting it run off an edge. By the time it shows up as a ceiling tile stain in a Florissant unit, there is usually standing water up there.
Access control, hatches and escorts
Getting onto a commercial roof is a procedure: keys or fobs, a hatch that may be padlocked, a ladder in a locked plant room, sometimes a site induction and an escort for the duration.
Sorting that out with the property manager in advance is the difference between a crew starting at seven and a crew waiting in the parking lot until nine. Where a tenant controls the only access, that conversation happens before the dispatch rather than on the roof.
Roof warranties and who is allowed up there
Most commercial membranes carry a manufacturer's warranty with conditions about who may work on the roof and what methods are permitted. Snow removal is generally fine; mechanical ice removal very often is not, and the wrong contractor with the wrong tool can void cover worth considerably more than the clearing.
The warranty gets read before the roof is walked, and the method used is one the document permits.
Membrane-safe means something specific
EPDM, TPO and modified bitumen all tolerate steam at low pressure and none of them tolerate chipping, scraping or a pressure washer. Crews steam the drains and scuppers open first to restore flow, then work the ponded ice, and they stay off seams and flashing details with the lance.
Mechanical units, conduit runs, solar racking and safety railing all get worked around rather than over.
Parapets hold the water in
A parapet is why a commercial deck ponds instead of shedding. Scuppers through the parapet are the only exit, and they are narrow, exposed on three sides and the first thing to freeze solid.
Steaming a scupper throat open is often the single highest-value twenty minutes of a commercial Florissant call.

Florissant Coverage and the Adjoining Communities
Crews working Florissant cover the adjoining communities on the same route — Hazelwood, Bridgeton, Saint Ann, West Alton and Earth City — 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 ice dams pages: St. Charles, University City, St. Louis, Kirkwood, Ballwin, Chesterfield.
When a storm hits Saint Louis County, crews are dispatched by severity rather than by call order — water already inside the house goes first.
Most jobs do not stop at one service. Commercial Ice Dams in Florissant often runs alongside commercial roof snow removal in Florissant, and both get written into one scope rather than billed as separate visits.
