Seamless gutters are made from a variety of materials which include vinyl, copper, steel and aluminum. An additional feature is they are made into several different color patterns. This makes seamless gutters desirable by many homeowners because they can match their home's color scheme. These types of joints may allow rain water to escape the gutter and drip down, possibly damaging your siding, splashing debris onto your house, or eroding your beautiful landscape. Seamless gutters virtually eliminate these weak links.
