How to clean gutters safely, from the ladder setup to the downspouts

Step by step: how to clean gutters safely, from the ladder setup to the downspouts

Safety first. Ladder falls are the real hazard here. OSHA says to keep 3 points of contact, never stand on the top three rungs of an extension ladder, extend it at least 3 feet above the roof edge, and set the base a quarter of its working length from the wall. CPSC warns that ladders touching overhead wires electrocute people cleaning gutters: assume every wire is live, keep the ladder at least twice its length from power lines, and do not work in wind. If the house is two stories or the ground is sloped, hire a professional.

1. 1

   Pick a dry, calm day and inspect the ladder

   Work when the roof and ground are dry and there is little wind. Check the ladder for bent rails, loose rungs and worn feet before you carry it out; OSHA says a damaged ladder should be taken out of use. Look up for overhead wires along the whole run of gutter.

2. 2

   Set the ladder at the right angle

   Place the feet on firm, level ground and lean the ladder so the base is 1 foot out for every 4 feet of height to the gutter. Extend it at least 3 feet above the roof edge, make sure the locks are engaged, and use a stabilizer so it rests on the roof, not on the gutter. Have a helper steady the base.

3. 3

   Scoop out the debris

   Climb with both hands, carrying the scoop and bucket on a hook. Start near the downspout and scoop leaves, twigs and sludge into the bucket, working away from it. Only clean what you can reach while your belt buckle stays between the rails, then climb down and move the ladder.

4. 4

   Flush the gutter with a hose

   Once the gutter is scooped out, run a hose from the end farthest from the downspout. Water should flow steadily toward the outlet. Standing water or overflow points to a clog, a sag or a section with the wrong slope.

5. 5

   Clear the downspout

   If water backs up, the downspout is clogged. Push a hose up from the bottom outlet or feed a plumber’s snake down from the top, then flush again. Take off any downspout extension and clear it too.

6. 6

   Check hangers, seams and slope

   While the water runs, look for drips at seams and end caps, loose hangers and sagging sections that hold water. Tighten or add hangers where it sags, and mark leaky seams to seal with gutter sealant on a dry day.

7. 7

   Make sure water drains away from the house

   Watch where the downspout empties. The water should be carried away from the foundation, not pooling beside it. Add an extension or drain pipe if it dumps right at the wall.

How to use a ladder safely for gutter cleaning

Set it up correctly, keep three points of contact, and move the ladder often instead of reaching. Falls from ladders cause many serious injuries, and gutter cleaning combines a tall ladder, a slippery roof edge and a heavy bucket.

• OSHA’s portable ladder safety card: inspect the ladder first, use it only on stable, level ground, keep two hands and a foot (or two feet and a hand) on it, face it while climbing, and never exceed its load rating, which includes your tools and bucket.
• Base distance: a quarter of the working length from the wall. A ladder that reaches 16 feet up to its support needs its feet about 4 feet out.
• CPSC’s ladder safety tips add: keep your body centered between the rails, only one person on the ladder, and have someone hold the base.
• Wear shoes with a good grip, and keep the rungs and your soles free of mud and wet leaves.

Why you need to watch for power lines

Because a metal ladder that touches an overhead wire can kill the person on it or holding it. The CPSC safety alert on ladders and electricity names gutter cleaning as one of the jobs where this happens, often when people move a raised ladder or it shifts in the wind.

• Assume every overhead wire, including the service line from the street to your house, carries electricity. Coatings on lines are not insulation.
• Keep the ladder at least twice its length away from the nearest overhead line.
• Use a fiberglass ladder with non-conductive rails near wires, and keep it clean and dry.
• Lower the ladder before you carry it, and if it starts to fall toward a line, let it go and call the power company.

Can you clean gutters from the ground?

Often, yes, for light debris on a one-story house. Telescoping gutter wands that attach to a garden hose, and gutter-cleaning attachments for leaf blowers and wet/dry vacuums, let you clear loose leaves without climbing.

They are less effective on packed, wet sludge and do not let you see the inside of the gutter, so climb (or hire someone) at least once a year to check for clogs and damage. If you clean windows or solar panels from a ladder, the same ladder rules apply.

Why clean gutters matter: water and wildfire

Clogged gutters overflow next to the foundation, and dry debris in them can catch embers. NC State Extension’s gutter guidance says to inspect gutters yearly and after major weather, keep downspouts and elbows clear, and carry roof water at least 10 feet away and downhill from the house.

In wildfire-prone areas, NFPA’s home preparation advice includes clearing dead leaves and pine needles from roofs and gutters, because embers can land and ignite debris there. Gutter guards reduce the work but still need an occasional check and rinse.

Mistakes to avoid

• Leaning the ladder against the gutter itself, which bends it and lets the ladder slide.
• Overreaching to one side instead of climbing down and moving the ladder.
• Using an aluminum ladder near the service wire from the street.
• Standing on the top three rungs of an extension ladder.
• Blasting debris into the downspout with the hose before scooping, which packs the clog tighter.
• Ignoring where the downspout dumps water, so it still pools at the foundation.
