Why Gutters Overflow in Heavy Rain

What this means for a homeowner

Overflow during heavy rain can come from clogged gutters, undersized gutters, small outlets, not enough downspouts, steep roof valleys, or poor slope. Gutter guards only solve the debris part of the problem.

Before requesting a quote, document where overflow happens, which sides of the home collect debris, whether downspouts discharge near the foundation, and whether the gutters are loose, undersized, or already leaking.

Use this guide as a filter: if the issue is debris, guards may help. If the issue is water volume, the solution may involve gutter sizing, outlets, downspouts, or drainage changes.
