Working at height on roofs with fragile elements is one of the most hazardous tasks in the construction industry. The risks associated with this work are significant, and the consequences of accidents can be severe, including serious injuries and even fatalities. In the UK, falls from height remain the leading cause of workplace fatalities, with many of these incidents occurring on construction sites. Therefore, employers and employees must understand and comply with the regulations and best practices for working safely at height, particularly when dealing with fragile roofs.

This comprehensive guide will delve into regulations for working at height and the importance of safety. By understanding and adhering to these regulations, construction companies can protect their workers, minimise the risk of accidents, and ensure compliance with legal requirements. Throughout this article, we will explore real-life incidents, discuss the legal and financial ramifications of non-compliance, and provide practical guidance on implementing effective safety measures to prevent falls from height on fragile roofs.

The Importance of Compliance with Working at Height Regulations

The Work at Height Regulations 2005 is the primary legislation governing safety when working at height in the UK. These regulations were introduced to reduce the number of injuries and fatalities resulting from falls from height in the workplace. The regulations apply to all industries, but they are particularly relevant to the construction sector, where working at height is a common occurrence.

The core principle of the Work at Height Regulations 2005 is that work at height should be avoided whenever possible. If working at height cannot be avoided, employers must ensure that the work is properly planned, supervised, and carried out using the appropriate safety equipment. This includes conducting a thorough risk assessment, selecting the right equipment for the job, and ensuring that workers are adequately trained and competent to carry out the work safely.

Compliance with the Work at Height Regulations 2005 is not only a legal obligation but also a moral imperative. By prioritising safety and adhering to these regulations, construction companies can:

  • Protect the health and well-being of their employees
  • Reduce the risk of accidents and injuries
  • Minimise the financial and repetitional damage associated with safety incidents
  • Demonstrate their commitment to corporate social responsibility
  • Avoid legal penalties and prosecution for non-compliance

Failing to comply with the Working at Height Regulations can result in severe consequences, including fines, imprisonment, and the revocation of licenses. Moreover, the human cost of accidents and fatalities is immeasurable, with far-reaching impacts on workers, their families, and their colleagues. Therefore, it is essential for everyone involved in working at height on fragile roofs to understand and adhere to the regulations and best practices for ensuring safety.

Common Risks and Real-Life Incidents

Working on roofs where there are elements of fragility such as roof lights and skylights, poses a multitude of risks, primarily due to the potential for falls from height. Fragile roof materials, such as asbestos cement sheets, corroded metal sheets, or rotten timber, can easily break or give way under the weight of a person, leading to a fall. Other risks include falling through roof lights, skylights, or gaps in the roof, as well as tripping or slipping on the roof surface.

Real-life incidents serve as stark reminders of the dangers associated with working around fragile roofs. In one case, a construction company in North Wales was fined £450,000 after a worker fell through a fragile roof and suffered life-changing injuries. The investigation revealed that the company had failed to properly plan and supervise the work, and had not provided adequate safety equipment or training to its employees.

In another incident, a roofing contractor in Yorkshire was sentenced to four years in prison after a worker fell to his death through a fragile roof. The investigation found that the contractor had not carried out a proper risk assessment, had not provided appropriate safety equipment, and had allowed work to continue despite knowing the risks.

These incidents highlight the severe consequences of non-compliance with safety regulations. In addition to the human cost, companies found to be in breach of the Work at Height Regulations can face substantial fines, legal costs, and repetitional damage. The Corporate Manslaughter and Corporate Homicide Act 2007 also allows for the prosecution of companies and individuals where a gross breach of a duty of care has resulted in a fatality.

To prevent such tragedies and ensure the safety of workers, it is crucial for construction companies to identify the risks associated with working on fragile roofs and implement appropriate control measures. This includes conducting thorough risk assessments, providing suitable equipment and training, and ensuring that work is properly planned and supervised at all times.

5 Key Regulations for Working at Height on Fragile Roofs

When working on fragile roofs, it is essential to adhere to the relevant health and safety regulations to minimise the risk of accidents and injuries. Here are the five key regulations to consider:

  1. Work at Height Regulations 2005: These regulations are the primary legislation governing work at height in the UK. They require employers to assess the risks, avoid work at height where possible, and use appropriate safety equipment and measures where work at height cannot be avoided. When working on fragile roofs, employers must ensure that the work is properly planned, supervised, and carried out by competent people, using suitable work equipment and fall protection systems.
  2. Construction (Design and Management) Regulations 2015: These regulations place duties on clients, designers, and contractors to manage health and safety throughout construction projects, including work on fragile roofs. They require the appointment of a principal designer and principal contractor to coordinate safety management, the preparation of a construction phase plan, and the provision of suitable welfare facilities on site.
  3. Personal Protective Equipment at Work Regulations 1992: These regulations require employers to provide suitable personal protective equipment (PPE) to employees working at height on fragile roofs. This may include safety harnesses, lanyards, anchor points, and other fall arrest systems. Employers must ensure that the PPE is properly maintained, stored, and used by competent individuals.
  4. Provision and Use of Work Equipment Regulations 1998 (PUWER): These regulations cover the selection, maintenance, and use of work equipment, including equipment used for accessing and working on fragile roofs, such as ladders, scaffolding, and mobile elevating work platforms (MEWPs). Employers must ensure that the equipment is suitable for the task, properly maintained, and used by competent individuals in accordance with the manufacturer’s instructions and relevant safety standards.
  5. Health and Safety at Work etc. Act 1974: This act sets out the general duties of employers and employees to ensure the health, safety, and welfare of all persons at work. When working on fragile roofs, employers must provide a safe working environment, safe systems of work, and adequate training and supervision. Employees have a duty to take reasonable care of their own health and safety and that of others who may be affected by their actions, and to cooperate with their employer in complying with health and safety requirements.

In addition to these regulations, there are several standards and guidance documents that provide specific advice on working safely on fragile roofs, such as BS EN 516:2006 (Prefabricated accessories for roofing – Installations for roof access – Walkways, treads and steps) and ACR(M)001:2014 (Test For Non-Fragility of Large Element Roofing Assemblies).

By adhering to these regulations and standards, and following the guidance provided, construction companies can ensure that they are taking all necessary steps to protect their workers from the risks of working at height on fragile roofs.

Implementing Safety Measures and Controls

To ensure the safety of workers on fragile roofs, it is essential to implement a hierarchy of control measures. This hierarchy prioritises the most effective measures first, with personal protective equipment (PPE) being the last line of defence. The hierarchy of controls for working on roofs includes:

  1. Elimination: The first step is to avoid working on roofs altogether, if possible. This may involve exploring alternative methods of carrying out the work, such as using a mobile elevated work platform (MEWP) or accessing the roof from underneath.
  2. Substitution: If work on a fragile roof cannot be avoided, consider substituting the fragile material with a more durable one, or using a safer method of access, such as a temporary platform or scaffolding.
  3. Engineering controls: These involve implementing physical measures to prevent falls, such as:
    • Installing guardrails or barriers around the perimeter of the roof
    • Using crawling boards or roof ladders to spread the load on fragile surfaces
    • Covering fragile roof lights or skylights with a suitable material
    • Installing safety nets or soft landing systems to mitigate the consequences of a fall
  4. Administrative controls: These include measures such as:
    • Conducting a thorough risk assessment and developing a safe system of work
    • Providing adequate training and supervision for workers
    • Implementing a permit-to-work system to control access to the roof
    • Establishing emergency procedures and rescue plans in case of a fall
  5. Personal protective equipment (PPE): This is the last line of defence and should be used in conjunction with other control measures. PPE for working on fragile roofs may include:
    • A full-body harness and lanyard connected to a suitable anchor point
    • Protective footwear with good grip and ankle support
    • Hard hats and eye protection to guard against falling objects
    • High-visibility clothing to ensure workers are easily seen

It is crucial that all safety equipment is properly selected, inspected, and maintained, and that workers are trained in its correct use. Regular inspections and maintenance should be carried out to ensure that equipment remains in good condition and is fit for purpose.

In addition to the hierarchy of control measures, there are specific products available that can help ensure safety when working on fragile roofs. One such example is the Valley Walk fragile roof cage protection system from APS.

Case Studies: Lessons Learned

Analysing real-life incidents involving work on fragile roofs can provide valuable lessons for construction companies looking to improve their safety practices. 

Case Study: Yorkshire Roofing Contractor Sentenced to Four Years in Prison

In this tragic case, a worker lost his life after falling through a fragile roof. The investigation uncovered a series of failures by the roofing contractor:

  • No proper risk assessment was carried out
  • Appropriate safety equipment was not provided
  • Work was allowed to continue despite the known risks

The key lessons learned from this case are:

  1. Risk assessments are a legal requirement: Failing to conduct a suitable and sufficient risk assessment is a breach of the Work at Height Regulations and can result in severe legal consequences. Risk assessments must be carried out by a competent person and reviewed regularly to ensure they remain valid.
  2. Safety equipment is a must: Providing appropriate safety equipment is not optional; it is a legal requirement. Employers must ensure that workers have access to the right equipment for the job and that it is properly maintained and inspected.
  3. Ignoring known risks is unacceptable: If a risk is identified during the course of work, it must be addressed immediately. Allowing work to continue in the face of known dangers is a gross breach of the duty of care and can result in criminal prosecution.

By learning from these incidents and applying the lessons learned to their own safety practices, construction companies can help prevent similar tragedies from occurring in the future. It is essential to prioritise safety at every stage of a project, from planning and risk assessment through to execution and completion. Only by fostering a strong safety culture and adhering to best practices can we ensure that every worker goes home safe at the end of the day.
