Sagging gutters are usually caused by one of three things: debris buildup that adds weight, improper installation, or failed fasteners. In Cold Spring Harbor, we see this a lot with older homes where the original installation didn’t account for our heavy snow loads and coastal storms.
When gutters sag, they can’t drain properly, which creates a cycle – poor drainage leads to standing water, which adds more weight, which causes more sagging. Eventually, the gutters pull away from the fascia boards entirely.
The fix involves properly re-securing the gutters with appropriate fasteners, correcting the pitch for proper drainage, and sometimes reinforcing the fascia boards if they’ve been damaged. It’s not a DIY job – improper installation will just lead to the same problem recurring.
