Why shingle replacement & roof replacement works differently in King
What makes shingle replacement & roof replacement in King 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.
Infill and renovation work in King frequently reroutes venting without re-sizing it, and undersized or over-long runs are the single most common cause of poor draft we see.
Post-war subdivisions across York share the same construction generation, so when one street starts showing the same defect, the neighbours usually follow within a couple of seasons.
Across Schomberg, Nobleton, Kettleby, Lloydtown and Ansnorveldt, 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 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.
