My new house is building and the scaffolding is up for the roof tilers at
the moment. There are 2 large peppermint trees that overhangs the top roof
of the house by about .5m - 1m.

I was thinking now would be a good idea to put some sort of gutter guards in
those areas of the roof. I am hoping to do it myself since the scaffold is
there.

I am looking for reommendation of the BEST product;
- That will last forever (as the roof will not be easy to get to once the
scaffold is gone)
- That is readily available in Perth (Bunnings?)
- That is easy to install
- No bushfire risk here - inner suburban
