Identifying Outlet Blockages Versus Run Overflow
Water issues along a roofline often come down to where the restriction sits. An outlet blockage typically occurs right where the gutter connects to the vertical downspout, causing water to back up rapidly at that corner even if the rest of the channel is relatively clear. In contrast, overflow along a gutter run usually points to heavy debris spread across the length of the channel, preventing water from flowing freely toward the drainage points. Describing where the water spills over helps define the necessary cleaning scope.
