Hi, Am renovating a house and there is a mono pitch roof over the extension. This around 12.5 degrees. I need to extend this do I need to use counter battens? The original plans said to use Anchor Centurion tiles, I can't find any info on these anyone heard of them?! The ones already on are Redland Grovebury concrete interlocking.
Any info/advice welcome.
Regards,
Dunc
