How does it work?

Great Barrier Leaf is crafted from arched high-density polyethylene (HDPE) for outstanding flexibility and no gaps. There’s no drilling, no screwing and no need to lift roof tiles to install. It features unique slots that allow water to pass through to gutters freely while leaves are removed naturally by the wind and rain. It also forms an arched barrier that temporarily slows water velocity – directing it into the slots for improved water collection in even the heaviest downpours.

Chris B

"Mate, thank you very much. I can't get up on the roof to do any of this anymore so last year I hired a bloke to do it, he charged me $400 and the job was terrible. The service from your Team was absolutely fantastic and I can't thank you enough and has taken a great weight off my shoulders the last thing I need at this time is a flooded house due to blocked gutters!"
