What makes roof inspection in Niagara-on-the-Lake its own problem
The honest summary of roof inspection in Niagara-on-the-Lake is that the work is simple and the diagnosis is not.
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.
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 Garrison Village, Virgil, Line 1, Line 2 and Randwood, 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 inspection 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.
