What is the best practice for eaves trough hanger spacing?

The best practice for eaves trough hanger spacing is 3 feet or 36 inches. This spacing helps ensure that the eaves troughs are adequately supported, preventing sagging and potential water overflow. Proper hanger spacing is crucial for maintaining the structural integrity of the troughs, especially when they are filled with rainwater or snow, which can add significant weight. By having hangers every 3 feet, the system can better withstand these loads and improve overall drainage efficiency. This recommendation aligns with standard construction practices and guidelines, emphasizing the importance of stability and proper water management in roofing systems.
