Why a steep roof needs more gutter, not less

Two houses with identical roof footprints can put very different demands on a gutter, and the variable is pitch. A steep roof does not collect more rain than a shallow one covering the same ground area, but it delivers what it collects much faster. Water accelerates down the slope and arrives at the eave with momentum, which produces two effects. The first is volume over time: the same total water arrives in a shorter window, so the peak flow the gutter has to handle is higher. The second is that fast-moving water tends to overshoot, launching off the roof edge and past the front lip of the gutter entirely, particularly on the lower portion of a long steep slope. Sizing calculations account for this with a pitch factor, effectively treating a steep roof as if it were larger than it measures. In practice it pushes borderline runs from 5-inch to 6-inch and adds outlets. It is also the argument for making sure the gutter is positioned correctly relative to the roof edge rather than simply hung level with the fascia, because a correctly sized gutter in the wrong position still misses the water.
