Why shingle replacement & roof replacement works differently in Brampton
What makes shingle replacement & roof replacement in Brampton unusual is not the technique, it is the age spread of the housing: a single route can cover 1910 brick and 2019 factory-built venting.
Older Brampton 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.
Infill and renovation work in Brampton frequently reroutes venting without re-sizing it, and undersized or over-long runs are the single most common cause of poor draft we see.
Across Downtown Brampton, Brampton West, Snelgrove, Fletchers West and Peel Village, 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 downtown Brampton, 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.
