Start with conditions, not a product
Roof area, valleys, tree debris, fascia condition, downspout placement, and the final discharge point matter more to long-term performance than gutter color.

Naperville context
Naperville's clay-heavy soils drain slowly, so where roof runoff actually goes matters more here than in areas with sandier ground. The City of Naperville's stormwater plan depends on storm sewers, detention basins, and overflow routes precisely because the ground can't absorb heavy rain quickly, and DuPage County's countywide floodplain ordinance reflects the same concern at a larger scale. The intense rain that has accompanied recent severe weather -- including the August 2020 derecho and a July 2024 storm line that produced a 75 mph gust at O'Hare -- shows how much volume a gutter and downspout system may need to move in a short window.
