I am finally getting around to installing rain gutters on my house. I'm tired of rain sheeting off my roof and causing problems with flower borders and a new patio I made with pavers (the rain comes off the roof in sheets and displaces the sand I put down between the pavers right where the water hits). I had a local guy give me a quote to install seamless vinyl gutters but it was more than I wanted to pay. I'm planning on going to Lowes this weekend and getting whatever they have and put up one test section to see how it goes. Has anybody put up their own gutters and can advise on anything special to avoid? I read somewhere that certain installation methods could cause the board behind the gutter to rot out, but don't remember what caused it. Thanks!
