Rain gutters

One of the things that annoys me about my house is the lack of rain gutters on the entire roof. It seems, based on my observations made while walking the dog, that the builders in my neighborhood only put gutters where there are exits from each house. Aside from just being cheap, I really don’t understand the logic in that approach. Yes, it is nice to avoid a waterfall by my front and back doors, but a waterfall around the rest of my house is not good for the yard. One of these days it will be a high enough priority for me to spend the money to fix it, but it is an annoyance that I really shouldn’t have to deal with.
