Winter in Evanston does not need a record storm to put water inside a house. It needs a roof with snow on it, an attic leaking heat, and one cold night. As part of our complete Evanston winter roof services, crews handle commercial ice dam removal across Cook County.
Why Evanston Roofs Dam Up: Cycling, Not Snowfall Totals
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.
That is the part homeowners miss. Total snowfall here is modest compared with the northern belt, so roofs in Cook County are often built and insulated as though ice is not a concern. Then a cycling week in January finds every weak eave at once.
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 Ice Dam Removal in Evanston: How The Work Runs
The pitched sections nobody plans for
Very few commercial buildings are flat all the way across. Entrance canopies, mansard faces, dormers over older frontages and the sloped transitions between roof levels all shed onto places where people walk.
Those sections behave like a residential roof and get worked like one - steam at the eave, snow guards noted where they are missing, and the pavement below cordoned while material is coming down.
Internal drains fail differently from gutters
A residential gutter overflows when it blocks. An internal roof drain just stops, and the water stays on the deck at depth until it finds a seam, a flashing detail or a pitch pocket.
Crews open the drain throat and then confirm flow in the leader below before calling it clear. An open drain over a frozen leader is not an open drain, and on an Evanston building that distinction shows up as a tenant ceiling two floors down.
Working around rooftop plant
HVAC curbs, exhaust fans, conduit, gas lines, solar racking and railing are all obstacles and all drift traps. The snow behind a large unit is usually the deepest on the roof and the ice under it the thickest.
Crews work around and under them rather than over, and anything running stays running.
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.

Neighborhoods and Towns We Reach From Evanston
Crews working Evanston cover the adjoining communities on the same route — Kenilworth, Lincolnwood, Winnetka, Morton Grove and Golf — 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 ice dams pages: Wilmette, Skokie, Glencoe, Glenview, Park Ridge, Northbrook.
Evanston sits inside the regular Illinois service area, so a crew is usually scheduled the same day or the following morning.
Most jobs do not stop at one service. Commercial Ice Dams in Evanston often runs alongside commercial roof snow removal in Evanston, and both get written into one scope rather than billed as separate visits.
