An important factor these days with working on ageing Super 6 roofs is safety: completing the project successfully without anyone falling through the sheeting, causing serious harm or death; (of which we know of two cases here in New Zealand since 2014) and nobody wants that. To prevent this, we have developed and had custom-made, at an investment of over $90k, our Specialised Walk-On-Roof System (The budget blew out somewhat, but by that time we were committed). It is made from lightweight aluminum, with an ingenious method of rolling it out to completely avoid walking directly on the Super 6 sheeting. It facilitates not only safe walking and working on the roof, but also even, uniform spraying patterns of the encapsulation agent with a spray-boom that slides up and down it. We also use the Walkway System to replace ageing skylights, which otherwise on a Super 6 roof, is a dangerous and difficult job. Overall, the job gets done quicker and more efficiently because our workers feel safe and confident that they aren’t in any danger of falling through the roof sheeting.
