Roof debris removal in Markham

The Rouge woodlots are why roof debris matters in Markham. Homes in Cornell, Berczy and Wismer that back onto the corridor collect leaf load on the rear roof planes all fall — debris that never touches the front yard, so it goes unnoticed until it washes into the rear gutters with the next rain. On the heritage side, the steep rooflines of Old Markham Village and Unionville shed most material on their own but bank it in the valleys, and a packed valley holds moisture against century-old shingles longer than anywhere else on the roof.

We run the blow-off as a $59 add-on (2026) to a cleaning visit, while the crew is already set up: loose leaves and grit off the surface, valleys cleared by hand where they are steep, and whatever lands in the troughs comes out before the downspout flush. No pressure washing, ever — on heritage shingles especially, stripping granules can end a roof years early. Pair it with the late-fall clean and the whole system goes into winter clear.
