You must consider the total length of the ladder to ensure that they reach from the eaves to the roof ridge. This way, it allows you to work from an angle not more than 75 degrees on the roof. A folding roof ladder is becoming more popular as an alternative to sectional roof ladders.

Some roof ladders would usually need a regular extension ladder to climb up on the roof safely. Make sure that at least three rungs above the gutter and use the roof ladder link clamps to lock the extension ladder to the roof ladder, making them more secure and less likely to slide apart. 

A universal roof hook kit is available in the market that can be clamped onto the top of any single section ladder or extension ladder.

There are also fixed roof ladders installed in commercial structures or buildings as a permanent or long-term fixture for when access to a roof is required year-round.

Ladder materials

Folding step ladderLadders can be manufactured from varied materials; however, the main three includes:




Wooden ladders are still preferred for their durability, low cost, and non-conductivity; but are prone to damage from insects and weather exposure. 

Aluminum ladders’ strength will mostly depend on the grade of the material used and have high weather resistance. It is a cheaper option than fiberglass ladders and is more lightweight than fiberglass, weighing up to 20 pounds only, making them easier to transport.

Aluminum ladders are suitable for indoor usage as well as outdoor projects. Since aluminum is a type of metal, this material may pose some hazards when exposed to electrical sources and tends to bend easily under pressure. 

On the other hand, fiberglass ladders are non-conductive, making them perfect for outdoor projects and roofing works. Unlike wood ladders, fiberglass is resistant to insect damage and exposure to weather elements. 

Fiberglass is more durable and stronger than aluminum since it will not easily bend and do not weaken in the heat, making them more flame resistant than aluminum ladders. Fiberglass ladders are safe to use near electric poles since it does not conduct electricity and are resistant to electrical shocks. 

Fiberglass is not a lightweight material, but it is often seen as a better investment despite being more expensive.

Ladder Safety

Climbing up to roof using ladderStatistics shows that there are thousands of people die each year from falls in and around the home, making it the leading cause of death. 

Around 30,000 people are injured each year by falls involving ladders because the victims violate the basic rules of ladder safety.

General Ladder Safety rules:

Make sure that when you set up your ladder, they are placed securely on a level surface and footing to prevent slipping or falling. Keep your body centered on the ladder.

Use ladders when working on anything not safely performed from floor level. Avoid using boxes, chairs, desks, bookcases, radiators, or makeshift supports to stand on.

When using a ladder, do not place it in front of doors or directly around any corner without proper warning signs, especially in each approaching walkway.

Do not lean too far or overreach in either direction while standing on a ladder, as it might cause the ladder to fall off or pull the ladder over sideways.

Climb and descend ladders cautiously and keep in mind to face the ladder during ascent, descent, and working.

At all times, have two hands and one foot, or two feet and one hand in contact with the ladder steps, rungs, and side rails. Always carry tools in a tool belt or use a hand line to raise or lower other heavy tools.

Wear clean, slip-resistant shoes with heavy soles to prevent foot fatigue.

The recommended maximum height a person should climb on the ladder is the third step from the top when using a straight ladder.

Make sure you do not climb higher than the second step from the top when using a step ladder.

Always consider the weather, never use ladders in high winds or storms even if it may seem like you can manage the breeze – the risk of injury is much greater.

OHSA Ladder Standards

Room with ladder exposed drywall, wood floor, and windowsThe following ladder standards are the OSHA 1910.26 specification: Source: OSHA

The ladder rungs and steps need to be treated to avoid the possibility of slipping or should be made from corrugated, knurled, dimpled, coated with skid-resistant material.

The bottom rails should be supplied with insulating, non-slip material for safety and security purposes.

Always inspect ladders for side-rail dents or bends, as well as all runt-to-side rail connections, hardware connections, and rivets for shear. Read more about ladder inspection and portable ladder safety at DIR.

Always clean ladders with solvent or steam cleaning, especially if there is an indication that it has been exposed to oil and grease or other slippery materials.

All ladders need to pass yearly inspection following OSHA 1910.26.

Wooden ladders should never be painted.

Do not use metal ladders while working with electrical fixtures or devices.

Avoid loading ladders more than their maximum intended load or their manufacturer’s rated capacity.

For portable and fixed ladder rungs, cleats and steps must be parallel, level, and uniformly spaced at least 10 inches apart and not more than 14 inches apart along the ladder’s side rails.

For step stool, ladders, rungs, cleats, and steps must not be less than 8 inches apart and not more than 12 inches apart between the center lines of the rungs, cleats, and steps.

For extension, trestle ladders, rungs, cleats, and steps must not be less than 8 inches and not more than 18 inches apart between the center lines of the rungs, cleats, and steps. The rungs, cleats, and steps must not be less than 6 inches or more than 12 inches.

How To Safely Use A Ladder?

Individual climbing up a blue ladderAlways inspect the ladder for loose or damaged rungs, steps, rails, or braces before using it. Check for loose screws, bolts, hinges, and other hardware.

Use the ladder as it is designed to be used and should only be used by only one person at one time.

Choose a ladder with a greater load capacity than your weight combined with any items you may carry on the ladder.

Do not join two ladders to form a longer one or use an ordinary ladder as scaffold platforms. Use the right ladder for the job.

When placing ladders at an angle, avoid placing them to an extreme angle. Make sure that there should be approximately one-fourth of the ladder length distance between the bottom and the supporting point. Always manage to have three points of contact on the ladder.

Do not move, shift, or extend ladders while in use.

Use ladders with non-conductive side rails, especially if the worker or the ladder can get in contact with exposed energized electrical equipment.

Ladder Care

Upper part of a ladderHomeowners tend to take things for granted because ladders are frequently seen and used. Make sure not to neglect ladder maintenance and avoid only provide care when obvious defects appear. 

Failing to maintain ladders can do more harm than good since it can compromise their stability and can increase the risk of injury for users. It is essential to know how to care for your ladders. Regular and proper ladder care and maintenance are necessary to ladder safety.

In handling ladders, make sure that before and after every use, your ladders are clean and free of oil, mud, grease, or any slippery materials that may make the steps or rungs unsafe. 

Avoid dropping your ladders because such a heavy blow may cause damage to the loosened steps or rungs and can even deform the ladder’s stiles.

Inspect ladders before using them and ensure no missing or lost rungs, damaged feet, faulty spreaders, rot, or decay in wooden ladders. Also, check for twisted rails and splintered surfaces. 

Ensure that all steps or rungs must be tight and secure to the side rails and all hardware and fittings are correctly attached to the structure. Make sure that the ladder base has a slip-resistant material. Test all movable parts to see that they operate without binding. 

Ensure that ropes and pulleys are in good condition and extension locks move freely and lock correctly. Check and make sure that labels are intact and readable. 

For a self-supporting step ladder, ensure that the two front legs should be of the same length, and the two legs at the back should also be of the same size. Check if the step ladders’ spreaders are intact and lock correctly.

When storing ladders, always keep them in a horizontal position on racks or wall mount that is supported every 2 meters to prevent sagging; and do not hang them from their rungs or stiles. 

For wooden ladders, make sure you store them in well-ventilated areas, away from dampness and not exposed to excessive heat. Keep fiberglass ladders in places not exposed to sunlight or other ultraviolet light sources. Do not expose fiberglass ladders to a temperature above 200°F.

Never paint wooden ladders because you may not be able to see cracks or other defects in doing so. However, you may use a clear sealer or wood preservative for protection. 

Keep in mind that ladders that have been exposed to fire or strong chemicals should not be re-used and should be replaced.

If you must transport ladders, ensure that ladders are properly secured and cannot easily bump against any objects as this can damage the ladders. When securing your ladder down on a roof rack, use clamps to reduce any ladder movement on the roof rack. 

If you are transporting a ladder that overhangs off your vehicle, be sure to attach a brightly colored marker to make sure that other road users see the end of the ladder. 

Ladder Cost

Ladder laid downLadders are priced differently since there are several types and sizes of ladders both in hardware stores and online. 

It is essential to know the kind of ladder and its cost since you may buy a low-quality ladder for a lot of money. It is important not to focus on price but also emphasize the quality of ladders you are buying.

On average, a decent quality household ladder costs around $100 to $300. However, you need to consider the design, material, and type of ladder – this may cause the price to increase.

In these times, you can buy type II and type III ladders online. A 20-foot extension ladder online, such as telescope extension ladders or conventional extension ladders, costs about $200 to $400. These are usually ladders suitable for personal use and simple heavy-duty construction projects. 

A 12 and 15 foot conventional and telescopic extension ladders are a bit cheaper online and mostly work well for projects that do not require heavy equipment cost between $100 to $300. More diverse pricing for ladders online is sold between $70 to $600.

Ladder Size Guide

Multi functional ladder Safe ladder usage depends primarily on using the right type and size for the job. Using a ladder that is not of the proper size can get in the way of your safety and your work efficiency.

It is choosing the right size of an extension ladder to buy concerning the gutter’s height or to the structure’s support point. If the gutter has a maximum height of 9 feet, the best size to buy is a 16-foot ladder that includes a 3-foot extension above the roofline. 

A 20-foot ladder is suitable for a support point height of 9 to 13 feet, while a 24-foot ladder is best for a 13 to 17 feet support point height. 

With a gutter height of 17 to 21 feet, the suitable ladder to buy is a 28-foot size ladder that includes a 3-foot extension above the roofline; and a 21 to 25 feet height requires a 32-foot ladder size.

If a support point is 25 to 28 feet and a height of 28 to 31 feet, using a 36-foot and a 40-foot ladder accordingly is the best choice to get the work done.

When choosing the right size of stepladder that assumes a vertical 12-inch reach, the following are the best-recommended sizes: For a maximum reach height of 7 feet, 8 feet, 9 feet, and 10 feet, consequently, it is best to buy a 3-foot, 4-foot, 5-foot, and 6-foot size ladder. 

While a height of 11 feet, 12 feet, 14 feet, 16 feet, 18 feet, and 20 feet maximum reach, it is best to use ladders with 7-foot, 8-foot, 10-foot, 12-foot, 14-foot, and 16-foot accordingly.

What Size Ladder To Buy?

Different sizes of ladderHow to reach a 20-foot ceiling: Lofty ceilings are the most challenging place to reach in your home, and so you need the best ladder that would allow you access to your high ceiling. 

Keep in mind that a person’s safe reaching height is a maximum of 4′ more elevated than the ladder’s height. 

So, if you require reaching a 20-foot ceiling, a 16-foot ladder is the most suitable size to use, and make sure this ladder has a 9-foot horizontal support point.

How tall of a ladder do I need? Selecting the right ladder height is more than knowing the required vertical size. 

Several aspects to bear in mind when choosing the right ladder length, include the ladder’s angle determining the highest fixed point on the ladder at about four steps down from the top. Knowing the required overlap of ladder sections and their extension above the roofline is essential.

Remember that if you use the ladder to access the roof or if the ladder is to be leaned against a roofline, the ladder needs to extend three feet above the roofline.

What size roof ladder do I need? Since there are many ladders to choose from, it is vital to find and match your ladder size to the project or job at hand.

Always consider your maximum reach height when shopping for your ladder because using a ladder that is too short or tall will affect your safety in doing your work.

The safest standing level on a ladder is no higher than two steps down from the top of a step ladder or four rungs from the top of a conventional ladder. Make sure that your ladder is several feet taller than the height you need to reach. 

Typically, a person has a vertical 1-foot reach; so, if your size is 5’1″, you can safely access a point 4 feet beyond the length of the ladder.

Keep in mind the sections in ladders up to 36 feet in length must overlap at least 3 feet and as much as 5 feet on longer ladders. When a ladder rests against any surface, it needs to extend 3 feet beyond the top support point.

When using an extension ladder, ensure that your ladder is 7 to 10 feet longer than the highest point.

Make sure that when setting up your ladder, it should be at the correct angle, with the base 1 foot out from the surface it rests against for every 4 feet of height to that point.

How To Secure A Ladder To A Roof?

Ladder attached to roofAlthough setting up a ladder may seem simple, doing roof work is often dangerous and terrifying to make certain everything is safe and secure when attaching a ladder to different roof types.

Begin by carefully checking the ladder for any damages. 

To secure a ladder to a roof, make sure to find a fixed object near the roof edge and set the ladder on firm, solid ground and carefully incline it into position making sure that you allow one foot of distance for every four feet of height away from the house or structure.

Use a cord or a specialized device when securing ladders by the roofline with a gutter. You can also use any strong cord such as a bungee cord, sturdy rope, parachute cord, or a solid wire to fasten your ladder to the roof.

Securely tie one end of the line onto the ladder’s top rung, then loop it around the top rung and the gutter. 

If there is no gutter running along the roofline, using a ladder lockdown or hook is a perfect way to stabilize your ladder from the ground. 

Make sure the roof hook is securely attached to the roof’s peak, allowing you to create a surface to anchor your ladder that would help stop shifts and help prevent situations where your ladder slides out from underneath you once you put your weight on it. 

On the ground, you can use 2×4 wood to level a big piece of plywood to form a platform for your ladder. Avoid using cinder blocks, bricks, rocks, or small pieces of wood to stabilize the base of a ladder.

Ladder inside a room Nowadays, platform ladders are preferred instead of Step Ladders as these platform ladders are safer and less fatigue on the user. 

Unlike step ladders where you could be standing on a thin 3″ ladder rung, a platform ladder allows the user to have both feet firmly standing on at least a 1’x1.5′ platform. 

As mentioned, a user should never stand higher than the 2nd to the top rung; the platform ladder is designed to have its platform at the right height where the user should stand safely, adding the functionality of a whole platform.

Fiberglass ladders are also considered the safest material for a ladder since they are non-conductive, so it is safe to use them near power lines and electrical wiring.

These types of ladder material are also durable, weather-resistant, flame-resistant, and built to last many years.
