In general, residential gutters come in two sizes and are made of either galvanized, copper or aluminum metal in a standard âKâ style. Other possibilities that might be found on an existing home would include plastic 4-inch sectional gutters or a half-round style gutter with round downspouts found on many turn-of-the-century-era homes.
The typical gutter system found on most Northern Virginia homes consists of 5-inch K-style gutters with 2-inch x 3-inch downspouts. An oversized gutter system would consist of larger 6-inch K-style gutters using 3-inch x 4-inch downspouts.
