When seasonal debris affects roof drainage

Leaves and other debris can slow the path from the roof to gutters, drains or outlets. Note when overflow or standing water appears.

Note where water stays after a storm and whether visible outlets are collecting leaves. Share the affected areas before scheduling a cleaning or maintenance visit so the crew knows what to inspect.

If you have a gutter, fascia or siding concern, tell Dekoven Roofing what you observed and ask about an assessment.

Debris blocks drainage

Leaves and debris can clog drains and gutters.

When it matters

  • After fall.
  • After storms.
  • Near trees.
  • On low-slope roofs.

Action

Clear safely or hire help. Roof drains on flat roofs are especially important.

Where debris collects

Debris collects at drains, behind rooftop equipment, in valleys and against parapet walls. A quick visual check after each season can show where it accumulates.

If trees overhang the roof, ask whether trimming is an option, since it reduces debris and shade that keeps the surface damp.

Check

Look for standing water after rain, which can point to a blocked outlet.
