How It Works

Where Did the Water Go?

Left

Right

Roof runoff moves: Pooling in the middle
Roof slope: Almost flat
Water on roof: 0.0 gal
Downspout capacity: 8 gpm
Water in gutter: 0.0 gal
Runoff captured: 0%
Water leaked inside: 0.0 gal

This test changes only the roof heights and gutter position. Storm size, roofing material, and gutter capacity stay the same.

1 in of rain on 1 sq ft yields about 0.623 gal. So 160 × 1 × 0.623 ≈ 100 gal.
