What makes roof cleaning in Kawartha Lakes its own problem
Homes in Kawartha Lakes rarely fail all at once — they fail slowly, through one heating season at a time.
Air-sealing and window upgrades have made Kawartha Lakes 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 Kawartha Lakes properties were re-roofed at least once without the flashing being re-detailed, leaving a cosmetic seal doing structural work.
Across Little Britain, Bethany, Woodville, Bobcaygeon and Pontypool, 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.
