What is the proper slope for guttering per 5 to 10 feet?

The proper slope for guttering is typically 1/4 inch per 10 feet of run. This slope is essential for ensuring that water flows efficiently toward the downspouts and does not pool in the gutters. When a gutter has the correct slope, it helps prevent issues such as overflowing, clogs, and water damage to the building's structure.

The choice of 1/4 inch is based on industry standards and best practices, allowing for adequate drainage without being too steep, which could lead to water running too quickly and potentially causing overflow at the downspouts. This balanced slope supports effective water management and contributes to the overall longevity and functionality of the gutter system.
