Every Wilmette 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 Wilmette winter roof services, crews handle commercial roof snow removal across Cook County.
The Wilmette Problem Is the Thermometer, Not the Snowfall
Three inches of snow and a week of days above freezing and nights below it will build ice on a Cook County eave just as reliably as a foot of snow further north.

The building stock has no margin for it. Because the winters here read as mild, attics tend to be under-insulated, eave details are less considered, and ice barrier is as often absent as present on a roof in Wilmette.
Ice-barrier practice in Cook County
The residential code Illinois follows requires eave ice barrier on new work, and Cook County enforces it. The variable on any given house is simply when it was last roofed.
Commercial Roof Snow Removal in Wilmette: How The Work Runs
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. Ceiling Sagging or Bulging After Snow.
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.
Sequencing so the load comes off evenly
Stripping one bay to the deck while the next still carries two feet creates exactly the unbalanced condition that overloads a member. Structures object less to a lot of weight spread evenly than to a moderate weight concentrated on one side.
Crews work in passes across the whole span, reducing everywhere before going deeper anywhere, and the sequence is set before anybody starts rather than left to whoever gets up there first.
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.
That is where crews measure on a Wilmette building, and it is why two roofs with the same snowfall can be in very different trouble.
Storm routes and standing contracts
Properties on a standing contract get a scheduled clear after each qualifying snowfall, with a single point of contact and a condition report per visit. For a portfolio, that means the clearing order is decided in advance by risk rather than by whoever calls first during the storm.
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 Wilmette with internal drains that means confirming flow below, not just clearing the grate.

Wilmette Coverage and the Adjoining Communities
Crews working Wilmette cover the adjoining communities on the same route — Kenilworth, Winnetka, Golf, Morton Grove and Lincolnwood — so a storm week usually means one truck handling several addresses in Cook County rather than separate trips.
Nearest hub towns with their own commercial snow pages: Evanston, Skokie, Glencoe, Glenview, Northbrook, Park Ridge.
When a storm hits Cook 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 Snow in Wilmette often runs alongside crane-assisted snow removal in Wilmette, and both get written into one scope rather than billed as separate visits.
