How Do You Fix A Sagging Gutter?
If a gutter sags too much, it looks unsightly, and if the sag is in the wrong direction, water collects, giving mosquitoes a breeding ground and creating leaks. It’s standard to pitch gutters 1/16 inch per foot (2 mm per 30 cm) toward the nearest downspout, but even a level gutter will drain. Assuming that the spikes, brackets or hangers are installed correctly, most commonly a gutter sags due to ice and snow damage or because a ladder has bent or dislodged its supports. Straighten a bent spike by pushing up on the gutter at that location with a pry bar (you’ll likely need a ladder to reach it); or remove a nailed gutter spike for replacement by locking the head of the spike firmly in a pair of locking pliers, then tapping the side of the jaws with a hammer to pull the spike out. Replace a spike that has fallen out or been removed with a threaded gutter spike. For a tighter fit, press a few wood slivers coated with exterior adhesive or epoxy into the nail hole first.
