We use two different gutter guard systems at Auckland Roofcraft. The hedgehog guttering system and the uminium mesh work on the same principle as all guttering systems, namely that the leaves that
generally fall into the gutter end up on the bristles of the hedgehog system or on the wire mesh, where the majority of it is blown away, where as gutters normally act as a trap for leaves, which normally get stuck in the residue of water left after a rain. Once
there, they tend to mulch down, staying wet long after the rain has passed. More leaves falling down on top of this mulch tend to get stuck and the gutter fills rapidly. The advantage, mainly with the hedgehog system, is that it is very easy to clean.
