WE ARE PLANNING TO ADD AN ADDITION TO OUR HOME. WE HAVE SEEN A POLYMER TYPE ROOF THAT RESEMBLES SLATE. CAN YOU TELL US WHO MAKES THIS TYPE OF ROOFING AND WHERE IT IS DISTRIBUTED? IS IT EASY TO INSTALL AND WHAT ARE THE ADVANTAGES AND DISADVANTAGES?
I'm not sure if this is what you're looking for, but it's one of the things I'm considering:
I have spoken with someone from London Ontario who has installed these and he likes the look, ease of installation, and durability. Hope this helps.
