Roof debris blow-off and clearing

Your roof is upstream of your gutters, and on canopy streets it holds a reserve: leaves banked in the valleys, maple keys behind dormers, acorns parked on low-slope sections, needles matting where two planes meet. Every rain converts a little of that reserve into gutter debris, which is how an eavestrough cleaned in October ends up overflowing by December while the trees stand bare. Clearing the troughs without clearing the roof above them buys weeks, not a season — the reserve just keeps billing.

The blow-off is priced as a $59 add-on to a cleaning visit because that is when it makes sense: the crew is already on the ladder, so the roof surface and valleys get cleared, guard tops swept, and whatever lands in the troughs comes out again before the downspout flush. One visit, whole system at zero. The method matters as much as the timing — we never pressure wash shingles, because stripping the protective granules ages a roof years in an afternoon and can void its warranty. Air, hands, and patience; photos when it is done.
