Why ice dam prevention works differently in New Tecumseth
Nearly every urgent ice dam prevention call we take in New Tecumseth began as something a homeowner noticed months earlier and reasonably decided to watch.
Air-sealing and window upgrades have made New Tecumseth homes far tighter than they were designed to be, and a tight house starves a natural-draft appliance of the make-up air it needs.
Many New Tecumseth properties were re-roofed at least once without the flashing being re-detailed, leaving a cosmetic seal doing structural work.
Across Alliston, Tottenham, Colgan, Treetops and Nicolston, 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 ice dam prevention 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.
