What size Gutter do I need?

The roof is one of the most essential parts of a building as it protects, occupants, contents, and the interior of the structure from the elements. The roof drainage system (guuters) is equally important. Factors that must be considered in the design of roof drainage systems are the area to be drained, size of the gutters, downspouts, outlets, slope of the roof, type of building, and appearance. The design capacity for a roof drainage system depends on the quantity of water to be handled. The quantity of water in turn depends on the roof area, slope, and rainfall intensity. Rainfall intensity is usually given in inches per hour for a five-minute duration based on U.S. Weather Bureau records. Baltimore’s rating for a 10-year storm is 7.1” per hour, for a 100-year storm is 9.7” per hour.
