Symptoms
- Visible gap between the gutter and the house
- Gutter sagging or dipping in a section
- Hangers or spikes loose or missing
Likely causes
- CommonWeakened or rusted gutter hangersOld spike-and-ferrule hangers loosen over time and let the gutter droop.
- CommonRotted fascia board behind the gutterWater trapped by the sagging gutter can rot the wood the hangers are anchored to, worsening the problem.
- PossibleWeight of debris, standing water, or iceA clogged gutter holding water or ice is much heavier than an empty one and stresses the hangers.
What to do
- Clean out the gutter first to remove excess weight from debris or standing water.
- Inspect the fascia board behind the sagging section by pressing on it; soft or crumbly wood indicates rot.
- Replace old spike hangers with modern screw-in hidden hangers spaced every 24–36 inches for a stronger hold.
- If the fascia is rotted, that section needs to be replaced before the gutter can be properly reattached.
- Re-check the slope toward the downspout as you re-hang the section.
- Keep gutters cleaned regularly going forward to reduce weight-related sagging.
- Have a professional replace larger sections of rotted fascia and rehang the gutter system if damage is extensive.
