Brock conditions that change how roof vent installation is done
Most Brock homeowners book roof vent installation for one reason and discover a second problem on the same visit.
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.
Many Brock properties were re-roofed at least once without the flashing being re-detailed, leaving a cosmetic seal doing structural work.
Across Gamebridge, Cannington, Wilfrid, Sonya and Beaverton, 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.
