Driving through my village today, I glanced up at some monstrous PVP installations about the size of a football field on a couple of roofs. It occurred to me to wonder how exactly these are fixed to the roof underneath, and I'm thinking that there is probably an industry 'proper' way, and a 'cowboy' way.
When I looked at these installations, they seemed to be spaced a good several inches above the tiles, which were 'standard' concrete types. Given that in general, these are 'loose-laid', and the PVPs are presumably fixed directly to them, does this gap between the tiles and the panel underside not represent a serious wind hazard ? It actually doesn't take a particularly high wind to move loose-fitted roof tiles on their own, so I'm thinking that with a bloody great sail above and fixed to them ... ?
