Question 1

How far apart should downspouts be?

Accepted Answer

The maximum distance between downspouts should be 40 feet for 5-inch gutters. For 6-inch gutters, up to 50 feet is acceptable. Each downspout handles about 600 square feet of roof area. In heavy rain areas, space them closer together.

Question 2

What size gutters do I need?

Accepted Answer

5-inch K-style gutters are standard for most residential homes. Upgrade to 6-inch gutters if your roof area exceeds 5,500 square feet, you live in a heavy rainfall area, or your roof has a steep pitch. Half-round gutters are aesthetically different but have less capacity than K-style.

Question 3

How many gutter hangers do I need?

Accepted Answer

Install gutter hangers every 24 inches (2 feet) for standard installations. In areas with heavy snow or ice, space hangers every 18 inches. Always place a hanger within 12 inches of each end cap and at seams.

Question 4

What slope should gutters have?

Accepted Answer

Gutters should slope 1/4 inch per 10 feet toward the downspout. For a 40-foot gutter run, that is 1 inch of drop. This ensures proper drainage without being visually noticeable. The low end connects to the downspout.
