Commercial roof debris removal calculator
Leaves, seed and sediment clog drains and scuppers, hold water against the membrane and add weight when they freeze. See a planning range for clearing the roof and any clogged drains before the Northwest Ohio winter.

Debris and drains before winter
In Northwest Ohio the leaves come down in October and November, and the first hard freeze is not far behind. Debris left in drains and scuppers holds water on the roof, and that water freezes, adds weight and works into seams. Clearing the roof after the leaves drop and again after snow melt in spring covers the two riskiest times.
Keep a log of which drains clog and when. A drain that backs up every fall may need a strainer, a guard or a look at the roof slope. Ponding that stays more than a day or two after rain is worth pointing out at the next inspection.

Fall and spring in Northwest Ohio
Leaves drop in October and November just before hard freezes, and snow melt in spring carries sediment to drains. Clearing after each keeps water moving off the roof.

Frequently asked questions
When should roof debris be cleared in Northwest Ohio?
After the leaves drop in fall, before hard freezes, and again after snow melt in spring. Those are the times drains are most likely to clog.
Why do clogged drains matter so much?
Water that cannot drain ponds on the roof, adds weight, freezes in winter and gets into seams. Keeping drains clear is one of the cheapest ways to protect a flat roof.
Is drain clearing included?
Enter the clogged drains separately. Our planning setting adds $139 to $600 for each, the lowest and highest published figures we found (national sources), from a simple strainer clog to a deeper blockage.
