These are some stuffed gutters!  This mornings project in Hillsboro, I came across this small section that has been over stuffed.  We should certainly clean them more often than the yearly visit we have to this home.  What could happen is all this debris that stays wet resting at the roof edge causes the water to wick up behind the gutter fascia board potentially causing rot or premature corrosion on the roof edge.  Not to mention the weight this section of gutter is holding can pull the gutters down. I suggested a 6 month partial gutter cleaning to ensure the proper functioning of the gutter system.

Another issue is the roof moss on this back hard to see side of the house.  This seems to be the only area at the home that collects moss growth like this.  We remedied it with a spray on moss inhibitor which should cause the moss to slowly die and hopefully go away.  An annual treatment of this area would be good preventative maintenance.
