The Short Answer

The six clearest signs of a clogged gutter are water sheeting over the front edge, stains running down the siding, plants growing in the trough, a dry downspout during rain, a sagging run, and water pooling at the foundation. Any one means the trough is holding debris or water it should be moving.

The Six Signs

First, water sheets over the front edge of the gutter during rain instead of draining to the downspout. Second, stripes or stains run down the siding below the trough line where overflow tracks the wall. Third, grass, weeds or saplings sprout from the gutter, which only happens when soil-like debris has built up. Fourth, the downspout stays dry in a storm while the trough overflows, a sign the pipe is packed. Finally, the run sags off the fascia under the weight of wet debris, and water pools against the foundation after rain.

What Each Sign Tells You

A dry downspout during overflow points to a clog in the pipe or elbow, not just the trough. Plants in the gutter mean the debris has been there long enough to break down into soil. Sagging means the weight has pulled the hangers, which can turn into a repair if ignored. Foundation pooling is the costliest sign, because the water that should have drained is now soaking the ground at the basement wall.

What to Do About It

A full clearing takes the debris out by hand down to the metal and flushes every downspout until it runs. A trough that still overflows after a quick scrape was never cleared to the bottom. If a corner keeps backing up after a cleaning, the clog is in the downspout below it. If the run sags or leaks after it is cleared, that is a repair, not a cleaning.
