Carolyn – I think we all agree that it’s logical for the roof-void to be insulated concurrently with the works on the new roof. How that’s funded depends upon the value of credits available to first floor Lot Owners under your State’s VEET Scheme if they pay individually, or whether your Owners Corporation (O/C) Resolves to itself allocate communal funds (i.e. of all 14 Owners of your Plan) to complete those concurrent works.
However, should your Owners Corporation (O/C) decide not to go in that direction, there would be no point in my opinion for individual Owners to attempt to seek a Ruling or Orders from the Victorian Civil and Administrative Tribunal (VCAT) to determine if the O/C should or needs to do something for which it is not responsible, because just like the NSW Consumer, Trader, and Tenancy Tribunal (CTTT) it takes a dim view of frivolous or vexatious Applications.
Again in my opinion, if insulation is professionally installed whether by the O/C or by individual Lot Owners and it’s a glasswool type of product, the imperative is for your O/C to clearly Resolve who has the responsibility for any on-going maintenance / repairs / replacements of the product and how the O/C will be informed prior to any future installations of down-lights, exhaust fans, and similar thru-ceiling items by Lot Owners, each of which has caused electrical fusions and fires within roof-voids when proper installation methods within insulated areas were not followed.
