Roof safety hook

When working on a pitched roof, where no collective protection measures have been implemented, you can use a roof safety hook to protect yourself from falling. Roof safety hooks are firmly connected to a load-bearing roof structure. A roof safety hook combines an eyelet, which is typical of an anchorage device, with a hook to which a roof ladder or roofer’s seat can be attached. These special roof hooks are manufactured, tested and labelled in accordance with EN 517.

Be careful! Don’t confuse them! Ladder hooks are NOT roof safety hooks.

What types of roof safety hooks are available?

In EN 517 , a distinction is made between two different types of roof safety hook:

Type A roof hooks are only tested for tensile force being exerted upon them in the direction of the fall line and may only be used when the user is located below the hook. In everyday usage, this is generally insufficient as it makes it difficult to work at the roof apex.

Type B roof safety hooks, on the other hand, can absorb tensile force exerted upon them in the direction of the fall line, opposite to the direction of the fall line or even laterally, parallel to the roof surface. Roof workers secured by type B safety roof hooks can move up to the roof apex and even over to the other side of the roof.

How are roof safety hooks used?

Not only can individuals use roof safety hooks to secure themselves by hooking their personal fall protection equipment (PPE) up to them, these hooks can also be used for attaching roofer’s ladders. They provide roof workers with a stable footing and can be used on roofs with a pitch of up to 75°. Care must be taken to ensure that the ladder is not hooked up using its top rung - and that it is not placed in a gutter.

Mandatory inspections

Although roof safety hooks are not official anchorage devices, they can still be used to secure individuals. Therefore, the same rules apply with respect to carrying out regular inspections and compiling appropriate documentation.
