A half body harness, on the other hand, is designed to be used in conjunction with a work positioning belt and is mainly used for positioning and restraint.

Weight Capacity

It is important to choose a safety harness that has a weight capacity that matches your weight. Make sure to check the weight capacity information before purchasing a harness to ensure that the harness can support your weight. A harness that is not rated for your weight can put you at risk if you were to fall.

Attachment Points

The attachment points are where the safety harness is clipped to an anchor point. Your safety harness should have attachment points that are suitable for your work environment. For roofing work, you will need to attach your harness to an anchor point that is secure and can withstand several times your body weight.

Comfort and Fit

A safety harness that is uncomfortable or doesn’t fit properly will not provide you with the protection you need. Make sure to choose a harness that is comfortable to wear for long periods and fits well. The harness should be adjustable to fit your body type and should not be too loose or too tight. Pay attention to the straps, padding, and ventilation features when choosing a harness for roofing work.

Quality and Durability

A safety harness is an investment in your safety and should be chosen with quality and durability in mind. Make sure to choose a harness that meets the relevant safety standards, such as OSHA and ANSI. Look for a harness made from high-quality materials that are resistant to wear and tear. A durable harness will last longer and provide better protection.

Maintenance and Inspection

Even the best safety harness will eventually wear out and need to be replaced. It is important to inspect your harness regularly and follow the manufacturer’s recommendations for maintenance and replacement. Check for signs of wear and tear, such as frayed straps or tears in the harness. If you notice any damage, stop using the harness immediately and replace it as soon as possible.

Choosing the right safety harness for roofing work can be a matter of life and death. By considering the factors above, you can find a harness that is comfortable, safe, and durable, and will provide you with the protection you need to work confidently and efficiently at heights.

Best Practices for Working with a Safety Harness on a Roof

Roof work is one of the most dangerous tasks you can encounter in construction, but a safety harness is one of the most effective tools you can utilize while working up there. It’s essential to not only use a safety harness but to correctly use it. The harness should be checked for any damage before each use, and all equipment should be in good condition.

Here are some tips on how to use a safety harness effectively while working on a roof:

1. Choose the right harness

When picking a harness, consider what work you will be doing and what type of roof you will be working on. Not all harnesses are created equal, so review the harness’s features to see if it’s the right one for you.

2. Find a secure anchor point

A secure anchorage point is what connects the safety harness to the building or structure. It has to be strong enough to support heavy loads and approved for fall protection. Make sure to examine the anchorage point and check for damages, corrosion, or wear before using it.

3. Adjust the harness to fit

The harness should fit tightly around your body, but not tight enough to cause discomfort or restrict movement. Before climbing on the roof, make sure that you adjusted the harness appropriately. If you’re not sure about the proper adjustments, reread the instructions or ask someone experienced in safe roof access.

4. Learn how to use the lanyard properly

The lanyard is the connection between the harness and the anchorage point. A lanyard is an adjustable rope or strap made of synthetic fibers, and it usually has a shock absorber built into it. Knowing how to use the lanyard correctly is crucial in preventing injuries. Here are some tips when using a lanyard:

  • Use a double-leg lanyard, so you remain tethered to the anchorage point at all times.
  • Check the lanyard before every use for any visible damage or signs of wear.
  • Make sure the lanyard is taut while you work to reduce fall distance.
  • Attach the lanyard to a secure point on the harness, such as the back or chest D-ring.

When falling, the lanyard’s shock-absorbing core reduces the impact of the fall. And also, it keeps the worker from bouncing off the surface, preventing a second impact.


A safety harness is an essential piece of equipment when working on a roof. Follow these best practices when using a harness to ensure fall protection, and reduce the risk of injury. The right harness, anchoring point, adjustment, and correct use of the lanyard will help you stay safe.
