There is no maximum height for using a ladder. However, where a ladder rises 9 metres or more above its base, landing areas or rest platforms should be provided at suitable intervals.
What is a good ladder for gutter cleaning? For a single storey house a leaning ladder with a height of 4m or more would be sufficient, taking into account that you should not be standing on the top 3 treads. For a two storey house you would need an extension ladder with an extension of around 7m.
The base of the ladder should be placed so that it is one foot away from the building for every four feet of hight to where the ladder rests against the building. This is known as the 4 to 1 rule.
Extension ladders range in length from 16 feet up to and exceeding 40 feet. All non-self supported ladders should extend a minimum distance of 3 feet past the edge they rest against but not more than 4 feet.
In the general industry, the height requirement for scaffolding is 4 feet above a lower level. For construction work, the height requirement is 6 feet above a lower level. All workers 10 feet above a lower level must have fall protection.
Although personal fall protection is required for workers exposed to a potential fall from an unprotected edge of six feet or more, fall protection is not required for workers on fixed ladders 24 feet or less, or on portable ladders of any height.
On a similar note, scaffold towers have their safe work load just like ladders do, so be careful not to exceed this. Taking more people, equipment or material onto the ladder than it’s explicitly designed to support can obviously open you up to severe risk – though thankfully, it’s one that most people manage to avoid.
The Health and Safety Executive (HSE) states that ladders need to be at an angle of 75 degrees away from the wall. This is known as the 1 in 4 rule. To get the angle right, you will need to know how far off the ground your roof is.
Use the 4-to-1 rule: Make sure the ladder is 1 foot away from the wall for every 4 feet that the ladder rises. For example, if the ladder touches the wall 16 feet above the ground, the feet/base of the ladder should be 4 feet from the wall.
A great tip to remember when using ladders is the “belt buckle” rule: stay centered and don’t let your belt buckle go past either side rail. Ladders should also be protected at the base to prevent pedestrians or vehicles bumping into them. When climbing to significant heights, a fixed ladder is advised.

E-ONE CR 137
The E-ONE CR 137 is the tallest ladder in North America, reaching more than 13 stories. Not only does this reach 137′ high, it extends 126′ horizontally to access the target.
Step ladders would include the length of the ladder when open as well as a maximum height you want to reach, calculated for an average person’s height of 5’9” with a vertical reach of 12”.
Get some rubber ‘boot’s to put on the top of the ladder – they help to prevent the ladder from leaving marks on the siding and cushion and widen the point of impact just a little bit. The main thing is to use your head making sure the top of the ladder is set well so it won’t move as you climb it.
about 3.3m
The gutter on a single-storey house is generally about 3.3m off the ground, so for single storey buildings a wise choice is often a two-section extension ladder with an extended height of 3.95m or more.
