What makes ice dam prevention in Mississauga its own problem
There is a rhythm to ice dam prevention work in Mississauga: a quiet summer, a frantic October, and a winter of emergencies that were visible in September.
Salt spray and road grit carried by winter wind accelerate corrosion on exterior metal components far faster in Peel than the manufacturer's rating assumes.
Post-war subdivisions across Peel share the same construction generation, so when one street starts showing the same defect, the neighbours usually follow within a couple of seasons.
Across Meadowvale, Rathwood, Dixie, Hurontario and Gateway, the housing stock changes street by street, and the correct method changes with it. A century home with a soft-brick stack does not get the same treatment as a 2010 build with a factory-built vent — using one method on both is how systems get damaged.
If you live anywhere near Square One, the practical takeaway is that a ice dam prevention visit should start with an assessment, not a tool. Any crew that begins work before telling you what they found is guessing on your behalf.
