Why roof vent installation works differently in St. Catharines
Nearly every urgent roof vent installation call we take in St. Catharines began as something a homeowner noticed months earlier and reasonably decided to watch.
The swing between a January cold snap and a February thaw can move a masonry assembly enough to open joints that looked sound in the fall.
Older St. Catharines stock was built when soft lime mortar and clay liners were the standard; modern high-efficiency appliances vent very differently, and the mismatch causes condensation the original builder never planned for.
Across Grapeview, Lakeshore, Applewood, Secord Woods and Rykert, 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 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.
