General information

Lifeline fastenings must sit no more than 5 metres apart and no more than 10 metres from the eaves. Snow fences are also regulated in accordance with the Public Order Act.

Definition of facade height

The distance from the intersection between the roof and the facade to ground level. For access devices, the facade height is calculated where the ascending devices are set up.

For protection devices on the roof, the facade height is calculated where the lowest ground level is measured.

Definition of roof slope angles

1:10 = approx. 6 degrees
1:3 = approx. 18 degrees

How high is your house?
