Insulated conservatory roof

PT18

Hi All, For some time I have intended to upgrade my existing twin wall translucent pvc conservatory roof to enable us to use more of the year. After trawling the internet my original intention was to remove the roof and replace with timber rafters ( plywood gusset to the apex) to stop spreading and take the weight of a velux window and ply boarding over tiled in lightweight tiles, I have building experience so know how to do so. Recently I have considered leaving the existing roof in situ (It is sound and weather proof)and fitting timber rafters to the underside of the existing aluminium ones, insulating with "superquilt" or the like, leaving an air gap for ventilation, fitting a velux, and boarding under in a lightweight twin wall pvc plank. Then rather than removing the pvc roof, batten it out and fit lightweight tiles over the top of it. Does anyone have any experience in doing the same? does anyone have any reason or opinion as to why this should not be done, or does it sound like a good solution ?

Hi PT18
Won't having tiles on the roof need building permission?
I have a polycarbonate roof on my conservatory which is too cold/hot for any plants. I am thinking of having insulation underneath the roof (inner insulation) finished with PVC or perhaps a plasterboard ceiling. I'm not sure how much this will cost but it would seem to be the most economical option.

We lined our existing roof with radiator foil and then used lightweight upvc cladding over that. Sorted
