What to do if…
your gutters are overflowing and water is cascading down the exterior walls

Short answer

Stay on the ground and prioritize electrical safety, then limit water entry and foundation exposure with temporary diversion and indoor containment until the storm eases.

Do not do these things

  • Do not climb ladders or get on the roof while it’s wet, windy, or during heavy rain.
  • Do not enter areas with standing water if it could be contacting outlets, cords, appliances, or the electrical panel.
  • Do not touch electrical equipment if it’s wet or if you’re standing on a wet floor.
  • Do not force water into a clogged downspout with a hose if you don’t know where it will discharge.
  • Do not start tearing out wet drywall while water is still actively entering.

What to do now

  1. Scan indoors for electrical risk and active entry. Check the inside of the affected exterior wall(s): dripping, wet window/door frames, damp around outlets/switches, water near light fixtures, or a sagging/bubbling ceiling.
    • If water is near electrical components, keep everyone away. Do not try to shut off power if you would have to stand in water or the panel area is wet.
  2. If it’s safe and dry to access, turn off power to reduce shock risk. Use the breaker panel only if you can reach it safely without wet floors/standing water. If you can’t, stay out of the wet area; call 911 if there’s immediate danger (sparking, burning smell, someone at risk).
  3. Contain immediately inside. Put buckets/towels under drips. Move furniture, rugs, and important items away from the wall and off the floor (especially on the lowest level).
  4. Do safe, ground-level downspout/drain checks. Clear only what you can safely reach: debris at the downspout outlet and any nearby yard/driveway drain grate that’s backing up.
  5. Temporarily divert water away from the wall and foundation. Attach a downspout extension or flexible drain hose and route discharge well away from the foundation to a spot that drains away from the house (as far as practical with what you have). If you don’t have one, make a short, weighted “chute” with plastic sheeting to guide water away from vents, window wells, and door thresholds.
  6. Reduce splash and wall saturation. Place a large container under the main spill point to cut splashback onto siding/brick, and keep water away from basement windows or window wells if applicable.
  7. Report street/storm-drain issues if they’re contributing. If a clogged storm drain, ditch, or street inlet is causing water to back up toward homes, report it to your city/county public works (often via 311, a local reporting app, or the city website).
  8. If there’s a flooding emergency, escalate early. If water is rising quickly, entering living areas, or anyone is in immediate danger, call 911 and follow local emergency management instructions.

What can wait

  • You don’t need to identify the root cause (clog, poor slope, undersized gutter, disconnected downspout, grading issue) while conditions are unsafe.
  • You don’t need to do “proper” repairs (resealing, rehanging gutters, replacing fascia) during the storm.
  • You don’t need to run fans/dehumidifiers right away if there’s any doubt about electrical safety or if water is still coming in.
  • You don’t need to make insurance decisions immediately if you’ve stabilized the situation and limited spread.

Important reassurance

This looks intense because roof runoff is concentrated at one failure point. Ground-safe diversion plus indoor containment is often enough to prevent the biggest, irreversible damage while you wait for safer conditions.

Scope note

This is first-steps-only guidance to reduce harm and buy time. Once it’s safe, further assessment (downspout clogs, gutter pitch, joint leaks, siding/brick gaps, grading, and drainage) may require a qualified professional.

Important note

This is general information, not professional advice. If you suspect electrical hazard, structural damage, or significant flooding, prioritize safety and contact emergency services or qualified help.
