Frequently Asked Questions
How much gutter do I need?
Measure the total length of all eaves where you want gutters installed. Most homes install gutters on all eave edges. Add up all sides to get total linear feet.
How many downspouts do I need?
One downspout per 20-30 linear feet of gutter is standard. Each downspout handles about 600 sq ft of roof area. Place downspouts at corners and avoid runs longer than 40 feet without a downspout.
How far apart should gutter hangers be?
Gutter hangers should be spaced every 3 feet (36 inches) in most climates. In areas with heavy snow or ice, space them every 2 feet for extra support.
