What makes roof winter prep in St. Catharines its own problem
The honest summary of roof winter prep in St. Catharines is that the work is simple and the diagnosis is not.
Infill and renovation work in St. Catharines frequently reroutes venting without re-sizing it, and undersized or over-long runs are the single most common cause of poor draft we see.
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.
Across Applewood, Fairview, Downtown St. Catharines, Old Glenridge and Glendale, 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 Welland Canal, the practical takeaway is that a roof winter prep 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.
