Until a year ago I had gutter helmets on mine. My house is surrounded by trees, both leafed and pines. For 20 years the helmets worked flawlessly and never needed any maintenance.
Had a new roof installed last year and the roofers would not put them back up, but did put new mesh gutter guards on. I spent an hour yesterday blowing maple seeds out of them. I pulled a downspout tube off and it was full of pine needles.
Yes, I miss the gutter helmets and am saving up for a new set.
