# 5" vs 6" gutters: Which do I need in Kansas City?

## Short answer

Most KC ranches and bi-levels under 1,500 sq ft of roof are fine with 5" K-style gutters. Larger homes (1,500+ sq ft), steep pitches (8/12+), or roofs with multiple valleys feeding into one section need 6" K-style. Kansas City summer storms can drop 3-4 inches per hour, so upgrading to 6" is rarely a wasted investment on larger homes.

## The longer answer

**The capacity difference:**

- **5" K-style** handles about 1.2 gallons per minute per foot. Adequate for ~600 sq ft of roof per downspout at average rainfall.
- **6" K-style** handles about 2.0 gallons per minute per foot. Handles ~1,200 sq ft of roof per downspout.

**When to upgrade from 5" to 6" in KC:**

1. **Roof area exceeds 1,500 sq ft.** KC storms can overwhelm 5" on larger roofs.
2. **Steep pitch (8/12 or steeper).** Steep roofs move water faster — bigger gutters handle the surge.
3. **Multiple valleys feeding into one gutter section.** Valleys concentrate flow.
4. **Current gutters overflow in heavy storms.** Direct evidence you're undersized.
5. **You're paying for a new install anyway.** The $1.50/ft upgrade cost is worth it for the headroom.

**When 5" is fine:** Single-story ranches under 1,500 sq ft, gable roofs with no valleys, no history of overflow, budget-conscious projects.
