Why roof inspection works differently in Cobourg
Cobourg sits in a freeze-thaw belt, and freeze-thaw is what quietly takes apart masonry, flashing and venting.
Infill and renovation work in Cobourg frequently reroutes venting without re-sizing it, and undersized or over-long runs are the single most common cause of poor draft we see.
Salt spray and road grit carried by winter wind accelerate corrosion on exterior metal components far faster in Durham than the manufacturer's rating assumes.
Across Elgin Park, Burnham Street, Northam, Division Street and White's Road, 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.
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.
