Why do my gutters overflow during rain?
Leaves, blocked outlets, poor slope, undersized drainage, or a restricted downspout can send roof water over the edge.
Urgency: moderate
What this means
Observe safely from ground level and keep roof water directed away from the foundation.
Safe checks
- Check visible downspout discharge
- clear only reachable debris using stable ground-level tools
- document where overflow begins.
Stop and get help if
- Do not climb a wet roof or unstable ladder. Use a qualified gutter or roofing service for height work or damaged components.
Which professional to call
Contact the matched licensed or qualified trade if safe checks do not resolve the issue.
