What makes shingle replacement & roof replacement in Niagara-on-the-Lake its own problem
There is a rhythm to shingle replacement & roof replacement work in Niagara-on-the-Lake: a quiet summer, a frantic October, and a winter of emergencies that were visible in September.
Older Niagara-on-the-Lake 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.
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.
Across Line 2, Randwood, Glendale, Line 4 and Old Town, 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 shingle replacement & roof replacement 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.
