Hi, first time poster but regular 'searcher'!
I am looking to turn an old single block (small) building into an office. The current roof is corrugated cement (containing chrysotile asbestos) and the back wall is also the garage wall of my neighbour (rear joist rests on the walls and is not fixed to the garage). I want to remove the current roof and add a 'flat' warm-roof; however, this will be next to my neighbour's (sloping corrugated bitumen) garage roof. I'm unsure if this is 'do-able' in order to maintain 'warm' and dry. We've just moved into the property so want to stay on our neighbour's 'good side'! I've attached a couple of pics of the current set up and a 'Sketchup' of my proposed idea. Any thoughts or advice (constructive!) are appreciated
