Guelph conditions that change how roof leak repair is done
Homeowners in Guelph 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.
Infill and renovation work in Guelph frequently reroutes venting without re-sizing it, and undersized or over-long runs are the single most common cause of poor draft we see.
Across Kortright Hills, St. George's, Parkwood Gardens, Riverside Park and Speedvale, 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 University of Guelph, the practical takeaway is that a roof leak repair 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.
