How to use a
roof ladder

When it comes to roof maintenance or repairs, safety should always be the top priority. One crucial tool in ensuring this safety is a roof ladder. This article aims to provide a comprehensive guide on how to safely use roof ladders.

This guide should also be read in conjunction with other advice given by authoritative bodies such as the Health and Safety Executive (HSE). Compliance with statutory instruments, such as the Work At Height Regulations 2005, should be ensured at all times, along with adherence to accepted codes of good practice and other relevant guidance. Ensuring comprehensive safety during roof work involves not just the proper usage of tools like roof ladders, but also a thorough understanding of the regulations and practices that govern work at height.

What Sort of Roof is Suitable to use a Roof Ladder?

A crucial aspect of roof ladder safety is using the ladder on an appropriate roof. Roof ladders are designed specifically for sloping roofs, not for flat surfaces or extremely steep pitches.

The roof's pitch angle is a key consideration when using a roof ladder. These ladders are generally designed for conventional residential roof pitches, which range between approximately 18 to 37 degrees. Using a roof ladder on a roof pitch outside this range can result in instability and poses significant safety risks.

Another essential factor is the length of the ladder. The ladder must be the correct length for the roof being worked on. It should be long enough to safely extend over the roof's ridge and provide secure access for the user. If the ladder is too short, it will not hook securely over the ridge, while a ladder that is too long can be unwieldy and challenging to handle safely.

Legalities Behind roof ladder safety

From a legal perspective, the use of roof ladders is governed by several safety restrictions and regulations. It's essential to familiarise yourself with these legal elements to ensure compliance and the safety of all involved.

Relevant Legislation

The use of roof ladders falls under several pieces of legislation. These laws provide a framework for ensuring the safe operation of ladders and other work equipment, as well as general safety standards for workplaces.

The Work at Height Regulations 2005

Among these, The Work at Height Regulations 2005 is perhaps the most relevant when it comes to ladder use. This regulation mandates that employers and those in control of any work at height activity must ensure the work is properly planned, supervised, and carried out by competent people. This includes the use of ladders.

These regulations emphasise the necessity of risk assessments, appropriate equipment selection, proper maintenance, and the provision of appropriate training. For instance, it states that ladders should only be used for work at height when a risk assessment has shown that the use of more suitable work equipment is not justified because of the low risk and short duration of use, or due to features on site that cannot be altered.

Importance of Competence and Knowledge

When it comes to rooftop competence, knowledge is undoubtedly power. Understanding these legal requirements and ensuring that all ladder users are adequately trained can help prevent accidents and legal issues. It's not just about compliance – it's about ensuring the safety and wellbeing of all those involved in work at height.

safety checks before using a roof ladder

Before using a roof ladder, conducting a series of thorough safety checks is essential. These checks help prevent accidents and ensure the efficiency of your work.

Ladder Inspection

You should inspect both the leaning ladder, used for initial access to the roof, and the roof ladder itself for any signs of damage or defects. This could include loose rungs, bent or cracked rails, corrosion, or missing safety components such as foot pads or ridge hooks. Never use a ladder that is damaged, as it could compromise your safety.

Correct Ladder Length

Ensure that both ladders are of the correct length for your task. The leaning ladder should extend at least 3 feet above the roof edge for safe access, while the roof ladder should be long enough to safely hook over the roof's ridge and provide a secure work area.

Personal Protective Equipment (PPE)

Before climbing the ladder, make sure you're wearing the necessary Personal Protective Equipment. This can include non-slip footwear to prevent slips and falls, a helmet to protect against potential falling objects, and gloves for a secure grip.

Setting up your roof ladder involves several steps, each crucial to ensuring safety during your roof work. This process begins with the correct set up and positioning of the leaning ladder for initial access to the roof.

Setting Up the Leaning Ladder

The leaning ladder should be secured at or near the top or bottom to prevent it from slipping. You can achieve this through the use of ladder stabilisers or by tying the ladder off to a secure point.

The ladder should be long enough to extend above the roof edge by at least 3 ladder rungs. This overhang allows for a safer transition from the ladder to the roof. Also, it's crucial to set the leaning ladder at the correct angle. Ideally, it should lean at an angle of 75 degrees to the ground, which is approximately a 1:4 ratio (for every 4 feet of height, the ladder base should be 1 foot away from the wall or edge).

Positioning the Roof Ladder

Once your leaning ladder is correctly positioned and secure, you can proceed to position the roof ladder. If you're using an adjustable length roof ladder, ensure it is at the right length before starting. This will help prevent issues once you are on the roof.

As you climb the leaning ladder, take hold of the roof ladder near the top where it feels well balanced. Once at eaves level, use the running wheels of the roof ladder to push it up onto the roof. Then, flip it over onto its bearers.

Ensure the ridge hook (roof hook) is securely located against the opposite side of the pitched roof. For decorative type ridge tiles, use a specially designed ridge or roof hook to prevent damage and ensure a secure fit.

The bearers fitted to the roof ladder should make full contact with the roof. This provides stability and keeps the ladder from sliding.

Securing the Roof Ladder

To provide added safety, secure the roof ladder to the leaning ladder to create a complete 'system'. This can be achieved through the use of a ladder tie-off or a similar secure system.

For an additional layer of safety, use restraint harnesses and running lines. These can prevent falls by keeping you securely attached to the ladder or roof.

Remember, always double-check your setup before beginning work. A secure ladder system is a fundamental part of safe work at height.

Climbing and Working on the roof ladder

Once your roof ladder is securely in place, you can begin to climb and carry out your work. Here are some crucial safety considerations to bear in mind during this stage.

Climbing the Ladder

When climbing the ladder, always maintain three points of contact. This practice enhances stability and minimises the risk of falls.

Never climb with tools or materials in your hands, which could cause you to lose your balance. Instead, use a tool belt or hoist materials up once you're safely atop the ladder. However, be cautious not to overload the ladder with materials or tools, as excessive weight could lead to instability.

Working Position

Ensure you're always centred between the side rails of the ladder. Leaning too far to one side could destabilise the ladder and lead to a fall. Keep your body square to the ladder, and avoid twisting or reaching excessively while working.

Footwear and Weather Conditions

Non-slip footwear is a must when working on a roof ladder. This can help prevent slips, especially in wet or damp conditions. Also, be mindful of weather conditions; if conditions become unsafe, such as in high winds or rain, it's best to abandon the job until conditions improve.

Dismounting and Overhead Hazards

When dismounting from the roof ladder onto the leaning ladder, be cautious and deliberate. Ensure your foot has a firm grip on the rungs of the leaning ladder before you step off the roof ladder. Always be aware of overhead hazards such as power lines, and maintain a safe distance.
