We only use and highly reccommend using a gutter mesh that does not sit in your gutters. We predominantly only use the 4mm Aluminium Leaf Mesh from Blu Mountain Mesh who are Australian owned and they manufacture the product in Brisbane. This mesh is screwed to the top of the gutter and is then screweed to the tin, or if you have a tile roof it goes underneath the second row of tiles. What makes this mesh superior to the rest is that it doesnt sit in your gutter therefor keeping the full flow and capacity of your gutters.

There a few different solutions rranging in size of the holes of the mesh, steel or aluminium and also mesh for valleys. the 2mm steel mesh has a higher fire rating making it a good solution if you live in a high fire danger area
