About surface mounted anchors
All types of surface mounted anchors are attached directly to the roofing by either rivets or some form of screws. Because of this method of attachment the life of the roofing that the anchor is attached to is reduced to only a few years .
By riveting any height safety anchor points to roofing material and using them as a fall-arrest safety device can cause far to many variables and make this type of practice unsafe, the risk of failure is far to high.
Corrosion of metal roofing
Metal roof and wall cladding is widely used in New Zealand and Australia for all types of buildings while the rest of the world has tended to restrict the use of metal cladding to farm, industrial and commercial buildings. In New Zealand 70-80% of housing is clad with metal roofs of long run or metal tiles, made, supplied and often installed by members of NZMRM. This is one of the reasons why the NZMRM executive agreed to invest a significant amount of money, time (4-6 years) and effort to investigate the specific causes for the deterioration that can occur when metal claddings are used in corrosive areas (predominantly by the sea) and determine how this can be avoided.

Stress that is caused by this type of anchor plays a large roll in reducing the life of the roofing iron. Roofing iron expands in the heat of the day and contracts as the day cools down. All Corrugate and Trapezoidal roofing is designed to curve or sag downward between the purlins that the roofing is fixed to.
When a surface mounted anchor is attached to the roofing it restricts the natural curve of the roofing iron between the purlins and places a greater stress factor on the anchor fixings. Within a short amount of time the roofing iron can crack at the fixings which
makes the surface anchor unsafe and the sheet of roofing iron the surface anchor is attached to has to be replaced
The installation should only to be carried out by a competent person as set out in the AS/NZS 1891.4:2009 Standards.
