The Volume Difference: 40% More Rain Capacity
5-Inch K-Style Gutters: - Water Volume Capacity: Approx. 1.2 gallons per linear foot. - Best for: Small ranch homes with simple gable roofs under 6/12 pitch and under 1,500 sq ft roof area.
6-Inch Seamless Gutters: - Water Volume Capacity: Approx. 2.0 gallons per linear foot (40% to 50% more holding capacity). - Best for: 2,000+ sq ft homes, steep pitches (8/12 to 12/12), homes with metal or tile accents, and rooflines with multiple intersecting valleys.
Downspout Upgrades: 2x3" vs 3x4" Commercial Outlets
A gutter system is only as fast as its drainage outlets. Standard 2x3" downspouts handle approx. 600 sq ft of roof drainage.
Upgrading to 3x4" oversized commercial downspouts doubles the discharge volume, preventing water from backing up in the gutter channel during 3-inch-per-hour NWA severe weather warnings.
