I had gutters all around this house when I bought it, with a new shingle roof already installed ~27 sq.....I almost immediately knocked off about 2/3 of the gutters from the house proper, the ones remaining go across the 2 car garage, back about 8' to the front door and across the door to the left about 15' worth....now here is the trick, they typical ~5" gutter top width....and they typically have a metal corrugated downspout rather limited in size...say 3x4" or so...at most......well they clog up all the time right on the top.....screw THAT, I bought a couple elbows and some length of 4" plastic DWV and glued it up, and blew out the gutter opening, 2' roof overhang, so down/back to wall, down again, and out away from house so each spout has 3 90* bends.....not cleaned the gutters in over 20 years now.....
GOD I"m lazy......
