How to Clean Gutters Safely
Published October 1, 2025 · Updated March 1, 2026
Clogged gutters cause water to back up under shingles, rot fascia boards, flood basements, and undermine foundations. Cleaning twice a year (spring and fall) takes a few hours and prevents thousands of dollars in water damage.

Safety First
- •Falls from ladders cause more DIY fatalities than any other home improvement activity. Ladder safety is non-negotiable.
- •NEVER lean a ladder against the gutters — they will bend and you will fall. Use standoff stabilizers that contact the fascia board.
- •Always maintain three points of contact. Never lean more than an arm's reach to either side — move the ladder instead.
- •Do not work alone. Have someone steady the ladder and know your location.
Step-by-Step Instructions
Choose Good Conditions
Work on a dry day — wet leaves are twice as heavy and much harder to remove. Avoid windy conditions that affect ladder stability. Dry, sunny weather makes the job faster, safer, and more pleasant.
Never work on a wet ladder or in windy conditions. Falls from even one-story heights can be fatal.
Set Up the Ladder Safely
Attach ladder standoff stabilizers (V-shaped arms that hold the ladder away from the wall) to the top of your extension ladder. These prevent the ladder from resting on gutters and provide a stable base against the fascia board. Set the feet on solid, level ground. For uneven ground, use adjustable ladder levelers.
Clear Debris Systematically
Start at the end farthest from the downspout and work toward it, pushing debris in the flow direction. Wear gloves — gutters contain sharp edges, stagnant water, and sometimes wasp nests. Scoop debris into a bucket hooked to the ladder. Work only within arm's reach from each ladder position, then move the ladder.
A bucket hook ($5) saves constant up-and-down trips. Alternatively, lay a tarp on the ground and toss debris directly down.
Remove Compacted Material
A garden trowel works better than a scoop for compacted, wet debris that's hardened into the gutter. Work carefully around gutter spikes or screws. Check for and remove any debris lodged at downspout openings.
Flush with Water
Once the gutters are cleared of solids, flush from the far end with a garden hose at full pressure. Watch water flow toward the downspout — it should run freely with no pooling. Pooling indicates a low spot from gutter sag. Check for leaks at seams and end caps while flushing.
A properly flowing gutter should empty completely within 30 seconds of stopping the hose. Any standing water indicates a slope problem.
Clear Downspouts
Insert the hose into the top of each downspout and run at full pressure. A clogged downspout backs up immediately. For persistent clogs, feed a plumber's snake from the top. For severe clogs, remove the downspout sections (they snap or screw apart) and clear each section individually.
Fix Sagging Gutters and Failed Spikes
Walk the roofline checking for gutters that sag in the middle — they retain water and accelerate rotting. Sag is almost always caused by failed gutter spikes (the original long nails). Replace them with 1/4" hex-head gutter screws ($8/box) by driving them through the gutter face and into the fascia board.
Gutter screws outperform spikes by a factor of 10 in hold strength. If your gutters are more than 15 years old and starting to sag, replacing all spikes with screws at cleaning time is excellent preventive maintenance.
Check Downspout Extensions
Ensure each downspout extension directs water at least 4-6 feet away from the foundation. Short or missing extensions are a leading cause of basement flooding and foundation settlement. Inexpensive flexible extensions and pop-up drain emitters that open under water pressure and close when dry are excellent solutions.
