Understanding Clogs and Runoff Conditions
Water issues along the roofline typically stem from two distinct situations that require different attention during a cleaning assessment:
- Outlet blockages: Leaves, twigs, or accumulated silt settle directly over the downspout opening, causing water to back up rapidly even if the rest of the trough is relatively clear.
- Mid-run overflow: Heavy accumulation along a long horizontal section can slow water transit, creating sagging points where water spills over the front edge before reaching an open drop.
