This page analyzes whether the Half-Round 6" gutter (capacity 7,200 sq ft at 1 in/hr) is adequate for a estate home (5,000 sq ft) across all standard roof pitches and rainfall intensities. An estate-sized home with approximately 5,000 square feet of roof area. Typical of luxury custom homes, historic mansions, and large multi-wing properties. Gutter sizing for estates often requires multiple calculations for different roof sections, each with its own pitch and drainage area. At a standard 4/12 roof pitch, the Half-Round 6" is adequate for rainfall intensities up to 1 inches per hour for this roof size. Use the comprehensive grid below to find the exact combination that matches your home's pitch and local rainfall.
Adequacy Grid: Half-Round 6" for Estate Home (5,000 sq ft)
The grid below shows whether the Half-Round 6" gutter has sufficient capacity for a 5,000 sq ft roof at each combination of roof pitch and rainfall intensity. Green cells indicate the gutter is adequate with the percentage of capacity used. Yellow cells indicate the gutter is near capacity (over 75% used). Red cells indicate the gutter is inadequate and will overflow during the design storm. This comprehensive view helps you determine if the Half-Round 6" is the right choice for your specific conditions, or if you should consider a larger profile.
