Houses, townhouses and a lot of flats
At the 2021 Census, about 4 in every 10 homes in Heidelberg were separate houses and about 4 in 10 were flats or apartments. Most of the rest were townhouses, semi-detached homes and terraces. The wider 3084 postcode is different: about 7 in 10 homes there were houses.
So the first question is whose roof it is. If you own a house, the roof is yours to use. A townhouse may come under an owners corporation, the group of owners that manages shared property. In a block of flats the roof is usually shared, so in most cases the owners corporation has to agree first. At the same Census, about 4 in 10 Heidelberg homes were rented, and in a rental the decision sits with the owner.
