Cook County sees the same pattern every winter: snow on the roof, warm air in the attic, and a line of ice building along the eave where the two meet. As part of our complete Hanover Park winter roof services, crews handle mold remediation across Cook County.
Why Hanover Park Roofs Dam Up: Cycling, Not Snowfall Totals
What catches people out in Cook 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 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 Hanover Park.
Ice-barrier practice in Cook County
Because ice is not the first thing a homeowner in Hanover Park 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.
Mold Remediation in Hanover Park: How The Work Runs
Clearance before the room is closed up
Before rebuild starts, the cleaned area is inspected again and, where appropriate, tested to confirm it is clear. Containment stays up until that point. Mold in the Attic After an Ice Dam.
The clearance result goes into the claim file along with the before photographs, the removal photographs and the moisture log.
The attic is the usual starting point
On most ice dam jobs in Hanover Park the worst growth is on the underside of the roof deck in the first few feet above the eave, exactly where the meltwater backed up. It often looks like a band of dark spotting running along the eave line.
Insulation along the same line is usually matted and stained. Both come into the scope together, because drying the deck while leaving wet insulation against it does not work.
Remediation, then the rebuild, from one company
Removing mold is only half a job if you then have to find someone else to hang drywall, re-insulate and paint. Ice Dam Now does the interior repair as well: new insulation, drywall, texture, trim and paint, so the ceiling that came down to get the mold out goes back up under the same scope and the same claim.
That also means one set of photographs and moisture readings runs from the first visit to the finished room, which is what an adjuster wants to see.
Interior repair by the same crews
Once the readings are at standard, the rebuild starts: new insulation to current R-value, drywall, tape, texture matched to the existing ceiling, trim and paint.
Doing the repair in-house keeps it in one scope and one claim, avoids the gap where a cleared room sits open waiting for another contractor, and keeps the documentation continuous from the first photo to the last coat of paint.
Attic mold: the sheathing, the rafters and the insulation
Most ice dam mold is in the attic. Meltwater backs up under the shingles at the eave, wets the roof deck from above, and runs down onto the insulation. Black spotting on the underside of the OSB or plywood along the eave line, darkened rafters and matted, stained insulation are the signs.
Wet insulation comes out and is bagged inside the containment. Affected sheathing and framing are HEPA vacuumed, cleaned and treated, or cut out and replaced where the wood has lost strength. Then the attic is dried to a measured number before anything goes back in.
