Homeowners across Mchenry County call about icicles. Icicles are cosmetic. The dam behind them, holding back standing water, is not. As part of our complete Algonquin winter roof services, crews handle commercial ice dam removal across Mchenry County.
Small Snow, Repeated Cycles: Algonquin Ice Dams
The snow totals here are unremarkable, which is exactly why Algonquin roofs get caught out. An ice dam needs meltwater and a cold eave, not a record storm.
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 Mchenry County all find out in the same week.
Ice-barrier practice in Mchenry County
Because ice is not the first thing a homeowner in Algonquin thinks about, the membrane is the detail most often value-engineered out of a re-roof. It is worth asking for by name on any quote.
Commercial Ice Dam Removal in Algonquin: How The Work Runs
Insulation above the deck changes the melt pattern
A modern commercial assembly puts most of its insulation above the deck, so very little building heat reaches the membrane. That is good for energy and it means the snow that lands mostly stays - the roof does not self-clear the way an under-insulated one does.
Where dams do form on those roofs it is almost always at a thermal bridge: a parapet, a curb, a drain bowl or a line of fasteners. Those are the spots crews work first.
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.
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.
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.
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 an Algonquin unit, there is usually standing water up there.
