I used to have a brick built out house shed at the bottom of the garden which I demolished about 20 years ago but the footings were left
Could I rebuild it with breeze block and a flat roof without going through planning
I have a Concrete garage with asbestos roof which is cracked and leaks
As not to disturb the asbestos I am considering covering it with a membrane and then putting new roof sheets on top
Please advise
What type of sheeting panels should I use? and best method of securing down
