Cambridge conditions that change how roof inspection is done
Homeowners in Cambridge tend to call us at one of two moments: the week before guests arrive, or the week after something started smelling wrong.
Snow load and ice damming stress the roof-to-wall junction each winter; by spring the sealant that was doing the work has usually torn.
Salt spray and road grit carried by winter wind accelerate corrosion on exterior metal components far faster in Halton than the manufacturer's rating assumes.
Across West Galt, Hespeler, Preston Heights, Central Preston and Speedsville, 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 the Grand River, the practical takeaway is that a roof inspection 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.
