What Size Ladder For 1 Story House

Getting the height of your ladder right can be complicated if you do not know exactly what factors to take into account and the right way to calculate the height depending on those factors. The exact height of the ladder that you need depends on the following:

There are many factors to be considered when calculating the required ladder size, but ideally, the size of ladder required for a one-story building is 14 to 16 feet in length.

Height of a One-Story House

The height of a one-story building may vary depending on the type and purpose.

For example, residential buildings are usually 8 feet or at the most 9 feet in height. Thus, taking into account the ceiling thickness, sloping roofs, and other HVAC allowances, the maximum height comes around 10 feet.

But building regulations in retail and office buildings require the height of the story to be at least 14 feet in total.

Thus, unless there are any specific rules or regulations in the specific place the building is constructed in, the height of a one-story building is between 10 and 14 feet.

Type of Ladder

The short working height ensures that you can use literally all types of ladders when working on one-story houses.

Before you calculate the height of the ladder, you need to find out the working height.

Once you do, you can use that to calculate the ladder height.

For non-supporting ladders like single ladders, telescopic ladders, and extension ladders, you can use this formula for calculation:

Height of ladder = Maximum Required Reach + 3 + Reach/4 (rounded to whole number)

All measurements are in feet. Here, the last factor pertains to the 4:1 rule of ladder usage while the 3 feet added before it is to account for the height of the extra part of the ladder that must be kept above the support point for safety purposes.

Things To Consider When Buying A Ladder For A One-Story House

Buying a ladder for a one-story house requires as much caution as buying a ladder for greater heights. Without the right safety features, even the lowest ladder can turn out to be a risk to use.

But look out for these and you will be fine:

Type of Ladder

Since the height of one-story houses allows a person to use any kind of ladder to work with, it all boils down to which type of ladder best suits the kind of work you are doing, the structure of the house, and your own comfort.

Some kinds of work, require more support and better footing, so self-supporting ladders are a better choice there.

The shape of the house and the structural features determine what kind of room is there to set up a certain kind of ladder.

Last, your own level of experience determines if you prefer self-supporting ladders or can work with non-self-supporting ones.

Height and Height Adjustability

It is important to get a ladder in the size range for the reach you need.

Make sure you have calculated the required height of the ladder before buying one.

Moreover, a height-adjustable ladder lets you work at different levels without having to get a new ladder for each job.

Build Material

The ladder material determines a lot of factors like weight, durability, hardiness, resistance to corrosion, and usability.

The most common materials are wood, aluminum, steel, and fiberglass.

Wood is not very durable while steel is too heavy.

Aluminum and fiberglass are the most popular materials, and while the former is preferred for being lightweight, the latter is preferred for its durability.

Electrical Safety

This is extremely important, especially if you will be working near electric lines or around water.

Fiberglass and wood are naturally insulating while steel and aluminum require plastic or rubber soles on the feet of the ladder and treads on the steps or rungs to impart insulation.

Slip Resistance

There are two areas where this must be applied. First, the soles on the feet of the ladder must be treaded to prevent them from sliding over the ground.

It can also have spurs to keep it immobile on softer ground. Similarly, end caps will also help in keeping the ladder stable against the wall in non-self-supporting ladders.

Second, the steps or rungs of the ladder must be treaded to prevent the person from slipping.

Leveling Features

Levelers are very necessary for ladders, especially if you know that you are not going to be working on flat ground or a smooth surface.

Levelers ensure that your ladder is not wobbly when you climb on it, nor will a slope result in the ladder sliding down the surface.

Duty Rating

Make sure that the duty rating of the ladder is sufficient for the height of the ladder and the total weight you plan to carry on it.

This is not something you should try to force the level of tolerance with. Carrying more weight than the rating can actually result in severe consequences, from damage to the ladder to disbalance.

Safety Guidelines

The ladder should cater to all the required safety guidelines that apply to it.

For ladders manufactured in the USA, this means the ANSI criteria must be followed while European ladders should be made according to the EN-131nstandards.

They should cater to the OSHA guidelines during usage.

Safety Precautions for Working With a Ladder for a One-Story House

No matter how good and safe your ladder is, if you do not use it safely, it will not protect you when you are mounted on it. Like any object of use, following safety precautions for ladders are essential to prevent avoidable accidents when using them. Some of these include:

Check Ladder For Any Damages –

Always make sure that the ladder does not have any damage or lose parts before you climb. A damaged ladder can potentially break mid-way and cause you to fall, and other accidents.

Check The Ground For Hardness And Level

The surface you are setting up the ladder on must be dry, hard, and flat.

A wet, soft, sloping, or rough ground can cause the ladder to wobble and destabilize, making you fall along with it.

Check For Water And Electricity Contact

Always take notice of any overhead or other electric lines before starting work. Avoid any electric lines.

If you just cannot, call the electricity board to confirm the power in the lines, have someone nearby at all times, and make sure medical support is nearby just in case.

The same goes for if you are working near water or wet surface, as this can carry current from elsewhere to you. Never ever work around naked wires.

Check That The Ladder Is Set Up Right

Before mounting the ladder, make sure it has been set up correctly.

It should follow the OSHA safety guidelines and other rules and conventions of ladder use.

Locks and spreaders should be set tight, the ladder should be opened fully or be at the right inclination, and should be tied to suitable support if necessary.

4:1 Rule

The 4:1 rule mandates that for every 4 feet of height the ladder is set up at. there must be 1 foot of distance from the wall of support.

This is, obviously, for non-self-supporting ladders only. This rule is in place to make sure that the ladder is never too vertical for it to tip over.
