id like to replace my conservatory roof with some sort of a tiled roof possibly vaulted.is this possible or too expensive to consider,. the conservatory is 5mx4m
Completely depends on the construction of the existing conservatory.
I doubt it tho. Most have no piers and only a lightweight frame/glass.
So you would need a set of A-frames which would defeat your objectives really.
I presume a lean-to rectangle at the moment?
By the time you've messed about trying to fit suitable supports into the existing framework........it'd probably be easier (and a similar cost) to take down your conservatory glass, build up the masonry walls (fitting steelwork where necessary) and fit a tiled roof for the Garden Room as a new-build rather than an alteration.
Check with your local council...Round my way, a conservatory doesn't need planning permission if it's over a certain percentage glass, (I think it's 75% - I forget the exact figure). But with a dwarf wall and tiled or slated roof construction it becomes a ''sun lounge'', which definitely needs planning permission here.
I had my polycarb roof changed to what looks like a 'proper roof'. The whole roof was removed and a new structure put in its place then covered with some sort of tile effect sheeting, fully insulated with a few thicknesses of insulation boards, then plasterboarded. Less noisy, somewhat warmer but cost more than a new conservatory with a polycarb roof!
