Roof debris removal in Thornhill

On a Thornhill split-level, debris on the upper roof does not stay there. Wind and rain move it down onto the lower roof and into the lower eavestrough, so a clean lower gutter can be full again after one storm. Roof valleys on the larger homes of Bayview Glen collect leaves too, and lots under the old oaks of Royal Orchard or backing the East Don valley catch debris on the roof for weeks after the street is bare.

Roof blow-off is a $59 add-on (2026) to a cleaning: we clear leaves and grit off each roof level and out of the valleys, then clear whatever lands in the troughs before the downspout flush. We never pressure wash shingles. On split-levels we suggest pairing it with the late-fall clean, once the oaks have finished dropping.
