Long rain plus organic debris is the gutter problem in this valley. Moss breaks off a shaded roof. Needles and leaves ride the water into the trough. The trough fills, water pours behind the fascia, and a bedroom ceiling shows a line that looks exactly like a roof leak. Sometimes it is a roof leak. Often the shingles are fine and the eave is the whole problem. A roofer, or a gutter contractor they trust, has to see which.
Downspouts that dump against the foundation are part of the same visit. Say whether water stands against the house after rain, and whether the trough is on the shaded side where moss is thickest. Metal roofs dump water faster than asphalt, so a gutter that was sized for shingles can overflow after a surface change. Mention a recent reroof if there was one.
This connection covers the ask. It does not publish a cleaning price, and it does not pretend a gutter is a roof. If the field of shingles is also open, use the repair page in the same call.
