• Structural stress: Heavy water loads can stress gutter mounting hardware
• Erosion concerns: Overflowing water can erode landscaping and damage foundations

High Humidity and Moss Growth

Washington's high humidity levels, averaging 70-80% throughout the year, create ideal conditions for moss and algae growth. This organic growth presents unique maintenance challenges:
