The ancient plastic roof on our conservatory has failed following a freak hail storm recently and is leaking in several places. I want to replace it with a slate tiled roof but I'm unsure if this is possible due to the weight.
The conservatory is rectangular, about 3m x 5m. Two of the edges are masonry walls (the house wall and a purpose built wall) the other two edges are wall-to-wall white PVC units forming an L shape.
The intent would be to build a timber frame that would sit on top of the PVC units and anchored to the walls on the other edges, then construct a 35 degree roof on top of this sloping upward to the house wall. So the PVC units are going to be taking 50% of the weight of the roof, evenly distributed.
No idea what the load-bearding capability of PVC units are - any advice on how to calculate?
