Multiplying that number by the local maximum rainfall intensity (6.8 inches per hour) yields an adjusted square footage of 7,480 square feet. Therefore, this roof should be equipped with 6-inch K-style gutters.

Roof area, the locale’s rainfall intensity and gutter capacity determine how many square inches of downspout are needed. Doubling the number of downspouts halves the required capacity for each.

## What angle should gutters be hung?
