Visible Gaps and Sagging: If you can see daylight between your gutter and the roofline, or if the metal is bowing downward, the hangers have failed and water is likely rotting your fascia.

Overflow and "Waterfall" Effects: Water spilling over the sides during rain—rather than flowing through the downspout—means heavy debris or improper pitch is forcing water toward your home's foundation.

Peeling Paint or Interior Water Stains: Moisture trapped against the house from leaky gutters will quickly blister exterior paint and can even migrate inside, causing unsightly ceiling spots and drywall damage.

Basement Dampness and Foundation Cracks: Misdirected water pools at the base of your home, which is the leading cause of basement leaks and expensive structural shifting in your foundation.

Pest and Mold Havens: Clogged, damp gutters are the perfect breeding ground for mosquitoes, carpenter ants, and hazardous mold that can eventually find its way into your attic.
