Just inspected my Seamless Fascia Guttering System (image indicative of mine) today for the first time since buying as I noticed that grass was growing out of one corner. On full inspection and wash through, discovered I have two 'neutral zones' (one outside corner & one inside corner) where there is no slope towards any drop outlets. Both zones are on opposite sides of the house. One zone (outside corner), where the grass was, is very easy to clean. The other zone (inside corner) is tucked away in the far back corner of the patio roof and a right bugger to get to.

Is there any "simple" way to put a slope on these two zones or am I just going to have to suck it up and get up there a couple times a year with the jet hose ?
