TYPES OF GUTTERS
Sectional
Sectional types are sold in 10- to 22-feet long pieces. They're made of vinyl, painted aluminum or prepainted steel. Gutter sections are joined together by Snap-in-place connectors. All sectional systems have end caps, corner pieces and drop outlets for connecting to downspouts. The negative to sectional systems is that there is a potential for leaks through all those seams. One positive is that they can be installed by either the homeowner or by a professional installer.
Seamless
Seamless gutters are the most popular type today. The biggest selling point is that they don’t have any seams which could potentially leak. The sections join only at inside and outside corners and at downspout outlets. Seamless gutters are usually formed from aluminum that has a baked-on finish, but they may be made from copper or factory-painted steel. They are made with a special machine that's brought to your home by a gutter contractor. These types of gutters can not be installed by do-it-yourselfers.
