Why roof flashing repair works differently in St. Catharines
Nearly every urgent roof flashing repair call we take in St. Catharines began as something a homeowner noticed months earlier and reasonably decided to watch.
Infill and renovation work in St. Catharines frequently reroutes venting without re-sizing it, and undersized or over-long runs are the single most common cause of poor draft we see.
Many St. Catharines properties were re-roofed at least once without the flashing being re-detailed, leaving a cosmetic seal doing structural work.
Across Grantham, Merritton, Applewood, Ridley and Burleigh Hill, 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 Welland Canal, the practical takeaway is that a roof flashing repair 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.
