What makes roof vent installation in Caledon its own problem
There is a rhythm to roof vent installation work in Caledon: a quiet summer, a frantic October, and a winter of emergencies that were visible in September.
Older Caledon 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 Mayfield West, Bolton, Mono Mills, Alton and Sandhill, 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.
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.
