Gutters were created to carry rainwater from your roof into downspouts and safely to the ground. At various times and for various purposes, gutters have been made from a number of different materials. Here are the most common types:
Aluminum Gutters - The most popular residential gutter type is made of seamless aluminum, known as formed K-style gutters. Aluminum gutters are strong and lightweight. Seamless aluminum gutters come in many colors and are formed into the shape and length you need at your home.
Wood Gutters - Wood gutters are rare, except for restoration work. They're also expensive, starting at about $15 per linear foot installed and, Depending on the wood species used, they can also be very expensive. running as high as $25 per linear foot. The original wood gutters were made from old growth cedar, a product that is rarely available today. Its substitution - new growth cedar or hemlock gutters have proven inadequate.
Copper Gutters - Copper is usually reserved for classic restorations. It's handsome, never rusts and never needs painting. They are expensive, but add value to your home and require less maintenance than aluminum or other materials. However, Copper gutters will oxidize and turn green over time unless they are treated. There are several sealants available that can be applied to keep copper gutters looking golden and shiny.
Steel Gutters - Steel gutters can stand up to ladders and fallen branches better than aluminum. But even thick galvanized steel eventually rusts through and need to be painted, inside and out. Stainless-steel gutters are strong and rust-free, and maintain their high sheen for years. But, like copper, stainless steel is expensive.
Vinyl Gutters - Vinyl is a commonly used material, often sold in hardware stores in six and 12 foot sections to do-it-yourselfers. Heavy amounts of rain can cause the material to bend and bow. Even a ladder put up against them can create serious damage. In regions with hot sunny temperatures, vinyl guttering will crack under the harsh conditions and break apart. They do not rust or corrode, however, and do retain their color; and can be painted, if desired.
Half Round and Quarter Round - style gutters with round downspouts are today only found on 19th Century era houses. They enable water to flow very effectively but they must be sized one inch larger than K styles to handle the same capacity. Hence, 6-inch half-round gutters are equivalent to 5-inch K-style.
Fascia Gutters - A fascia gutter is a rainware system that is fixed to a fascia board. It is often a custom made rainwater gutter that is fixed to the ends of the rafters and also performs the function of a fascia board. It is most commonly found in the Western part of the United States.
Integral Gutters were a popular gutter style in the 1960's. The end of the rafters and fascia on a sloped roof forms this system. The gutter is lined with a built-up roofing material and is able to hold a great deal more water than most of the other types of gutters. The disadvantage of this gutter style is in the potential for leaks, which can result in damage to the framing, fascia, soffit, and sheathing of the roof. The lining must be replaced or repaired every five to ten years.
