I can't think of the name of this material at the moment and have searched the net to no avail so far. They are made to look like tiles/slates but come in sheets measuring about 8x4 ft. They are light by comparison with the real thing and would suit the roof I need to cover. Can anyone refer me to a website dealing with them or give me any details as to how they are installed? Thanks for the info!!!
There are many kinds of polycarbonate and steel corrugated roof panels on the market, and where I live they don't meet the building codes. They are fine for an outbuilding, porch, greenhouse, or polebarn, but not for use on a habitated structure. Make a call to the local building inspector and ask him, also ask him if they are acceptable for your intended use.
4' x 8' plywood is often used to 'sheath' a roof. Corrugated metal or fiberglass/plastic has been used to cover roofs and they can come in 4 x 8 sheets I don't believe the fiberglass/plastic, or that formica, (which is what I think you mean by 'plastic tiles/slates) will satisfy most fire codes.
