Do strata townhouses need to install anchor points on each roof?

Anchor points should only be installed if there is an expectation to inspect/access the roof on a regular basis. Anchor points need recertification every 12 months, which is a cost to the owners corp so avoid them if you don't need them.

Any contractors undertaking works on a roof (roofing/solar/other) should install temporary systems to facilitate their installation or maintenance (edge protection, temp anchors, temp static lines etc) and/or propose permanent installations that should be considered for future maintenance of the systems/equipment that they install.

Also note that any worker who accesses a roof and/or works in a fall restraint/arrest should be qualified to work at heights and their equipment should also be tagged and in good condition.
