Niagara-on-the-Lake conditions that change how roof vent installation is done
If you mapped our Niagara-on-the-Lake service calls on a calendar, you would see the same shape every year: the problems are created in February and paid for in November.
Many Niagara-on-the-Lake properties were re-roofed at least once without the flashing being re-detailed, leaving a cosmetic seal doing structural work.
Air-sealing and window upgrades have made Niagara-on-the-Lake homes far tighter than they were designed to be, and a tight house starves a natural-draft appliance of the make-up air it needs.
Across Chautauqua, Line 3, Virgil, Glendale and St. Davids, 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 Shaw Festival, the practical takeaway is that a roof vent installation 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.
