Seamless gutters are a single continuous piece of gutter often cut from one single-coil piece of metal, typically aluminum. Seamless gutters are stronger and more reliable than sectional gutters because it is one piece of gutter which provides added rigidity and strength.
Also, because seamless gutters are made up of one continuous piece of gutter, they substantially reduce the chances of leakages. Since most leaks happen at the gutter joints, leaks will be essentially eliminated because there will be zero joints unless you have inside or outside corners. No leaks means no mold, rot, or water damage to your home and property caused by leaky gutters.
Seamless aluminum gutters are also available in a wide variety of colors, so you can closely match existing trim or roof color. Or you can find a color that compliments the exterior of your home.
The practical advantage of having your home equipped with a seamless gutter system is that it virtually nullifies the cost of maintenance since seamless gutters have a long life expectancy. They have the absolute minimal amount of joints and will never rust.
