Hamilton conditions that change how roof inspection is done
If you mapped our Hamilton service calls on a calendar, you would see the same shape every year: the problems are created in February and paid for in November.
Wind loading off Lake Ontario pushes driving rain against the south and west faces of a house, which is why water entry so often shows up on one side of a Hamilton home and nowhere else.
Infill and renovation work in Hamilton 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 Dundana, Mount Hope, Waterdown, Dundas and Twenty Place, 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 Bruce Trail, 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.
