Gutter fascia board sagging: What to Check and What to Do Next
A sagging gutter and fascia board should not be corrected by simply driving in new fasteners. Water overload, a blocked or undersized gutter, loose hangers, rotten fascia, roof-edge runoff, or structural movement may be involved.

Gutter Sagging Loose Hanger: What to Check and What to Do Next
A loose hanger can let a gutter drop out of its designed fall, so water may pool at the low spot, spill over the front or back, or pull the gutter and its fasteners farther from the fascia. Start from a safe ground-level position: photograph the full run, compare the low point with nearby supports, and observe the water path during light rain if that can be done without climbing or touching the gutter.

Gutter sagging with a visible dip: What to Check and What to Do Next
A visible dip means the gutter may have lost support, pitch, or both. From the ground, note whether the sag is between hangers, whether the gutter is pulling away from the fascia, and whether debris or standing water is adding weight.

Gutter sagging with water pooling: What to Check and What to Do Next
Water pooling in a visibly sagging gutter usually means the run has lost its fall toward the downspout, but a blocked outlet, wet debris, loose hanger, pulled fastener, damaged fascia, or permanently bent section can be the reason. From the ground, photograph the low point and trace the outlet and downspout.

Gutter sagging: What to Check and What to Do Next
Do not use a ladder, climb onto the roof, touch the gutter, or try to refasten it yourself. From safe ground-level and indoor viewpoints in calm, dry conditions, look for a low span, a changed slope, separation from the fascia, overflowing during a recent rain, detached joints, downspout separation, or water and soil erosion near the foundation.
