Some say that it's not good to have gutters on your home. Others swear by them and make sure to have them all around the roof of their homes. As you know they route the rain water from falling down beside the foundation and out to another area to run off. At times certain storms will damage them, by lashing limbs against them from high winds. Looking for replacement gutter stuff means going to the local hardware store. I believe there is also a online place to shop for these materials at the above link.
