If you are in North Chicago watching icicles grow along the gutter line, what you are really watching is water that no longer has anywhere to drain. As part of our complete North Chicago winter roof services, crews handle commercial ice dam removal across Lake County.
Why North Chicago Roofs Dam Up: Cycling, Not Snowfall Totals
An ice dam needs meltwater and a cold eave, and North Chicago supplies both on an ordinary week. A thin cover that melts by lunchtime and sets again after dark is a perfectly good dam factory.

Because the winters read as mild, the building stock is not built for ice. Attic insulation is thinner, eave details are less considered, and ice barrier is more often absent than present on a roof in North Chicago.
Ice-barrier practice in Lake County
Ice-barrier membrane at the eaves is required on new work under the residential code Illinois follows, but on a roof built before that it is frequently absent — and this is the region where it is most often skipped.
Commercial Ice Dam Removal in North Chicago: How The Work Runs
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.
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 a North Chicago building that distinction shows up as a tenant ceiling two floors down.
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.
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 North Chicago unit, there is usually standing water up there.
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.
