Observe from a safe location
Ground-level observations during or after rain can show where overflow or concentration occurs without climbing.
Think beyond the gutter
Downspout discharge, grading and site drainage influence where water goes next.
Repeated overflow deserves cause finding
Debris, ice, slope, outlet capacity or roof geometry can produce different solutions.
Height changes the DIY boundary
Upper-storey or difficult-access work should be treated as professional service.
Safety boundary. General planning information only. Do not open, dismantle or work on hazardous electrical, gas, structural, fire-protection or contaminated-water systems unless you are appropriately qualified and authorized.
