Inverted Roof Docklands
Inverted roofs, or upside down roofs, have the insulation laid onto the waterproofing membrane. There is normally some ballast to hold the insulation down. The problem with this kind of flat roof is that if maintenance is needed or there is a leak from the flat roof, it’s very difficult to find the leak, as you will see large areas of the insulation have to be removed, just to look at the flat roof covering.
