What makes shingle replacement & roof replacement in Oshawa its own problem
The honest summary of shingle replacement & roof replacement in Oshawa is that the work is simple and the diagnosis is not.
Infill and renovation work in Oshawa frequently reroutes venting without re-sizing it, and undersized or over-long runs are the single most common cause of poor draft we see.
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 Oshawa home and nowhere else.
Across Columbus, Vanier, Donevan, Windfields and Lakeview Oshawa, 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.
