The local factors behind roof cleaning in New Tecumseth
Two houses on the same New Tecumseth street, built the same year, can need completely different roof cleaning work — and usually do.
Many New Tecumseth properties were re-roofed at least once without the flashing being re-detailed, leaving a cosmetic seal doing structural work.
Salt spray and road grit carried by winter wind accelerate corrosion on exterior metal components far faster in York than the manufacturer's rating assumes.
Across Loretto, Nicolston, Colgan, Tottenham and Tecumseth Pines, 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 roof cleaning 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.
