What are the Different Types of Roof Gutters?

Most roof gutters have an interior that is U-shaped and serves as a channel to direct the flow of rain as it runs off the edges of roofs. Gutters are often made of vinyl, but can also be purchased in wood, aluminum and copper. Sometimes roof gutters are made of steel, but because of the probability of rust, steel is not considered a popular option.

Aluminum roof gutters are lightweight and generally easy to install. In addition, they are often less expensive than other types of gutters. These gutters can be painted to match roof overhang or left in their original condition. One of the possible problems with aluminum gutters is that they may not last as long as some other types, and when overfull, aluminum gutters may sag. Usually, sections that sag will need to be replaced with brand new guttering.

Vinyl roof gutters are another option that is considered affordable and easy to install. In addition, vinyl type guttering generally requires very little maintenance, and can be purchased in many sizes and colors. When sections of guttering need replacing, the process is usually simple enough for most homeowners to handle on their own without the added cost of a contractor. One drawback to using vinyl rain gutters is that vinyl can sometimes crack after repeated exposure to severe heat or cold. In particular, dramatic changes in temperature can also shorten the lifespan of the vinyl gutters.

Copper roof gutters are not only visually appealing, but they offer the added bonus of strength and durability. Most experts recommend copper gutters over aluminum or vinyl because they usually last for many years and can hold up to a great deal of weight without sagging. Over time, oxidation may cause copper to discolor but many people prefer the overall appearance of old copper. Most of the time, aged copper turns a mottled greenish brown, which could be particularly well suited to rustic style homes. For homeowners who want their gutters to stay bright and shiny, sealants that prevent oxidation can be applied to the guttering.

Rain gutters are considered essential to roofs that have very little overhang or roofs that have very little pitch. Overhang is the portion of the roof that extends beyond the underlying structure. If a roof has a great deal of overhang, rain runoff may not be a big concern, and guttering systems may not be necessary.
