After all, a 456-foot seamless gutter is much longer than an American football field. In fact, it's six feet longer than a Canadian football field, which extends 110 yards (instead of 100) from one goal line to another and has 20-yard deep end zones. Most importantly, 6-inch gutters can handle approximately 40% more volume than a 5-inch seamless gutter system. The Thompson Creek replacement gutter system even reduces the need for regular maintenance, as it includes hoods that filter out a large amount of common waste.
However, if you want to install a completely new gutter system, you'll need to take some measurements on the roof to understand which gutter size is best. If you already have gutters installed and need to replace all or part of the system, you can measure the existing gutters to determine their width. Many homeowners have found that their smaller 5-inch seamless gutters seem to overflow more easily in heavy rain. When installing gutter systems in large office buildings, commercial buildings, and residential homes with large volumes of water, a 6-inch gutter is the best solution.
