What is the required gutter slope?

The correct answer regarding the required gutter slope is based on standard practices in roofing and drainage systems. A slope of 1 inch in 16 feet is generally recommended as it allows for proper water flow and drainage, minimizing the risk of water pooling or backing up in the gutter system. This slope ensures that rainwater and debris are efficiently directed away from the roof and building structure, reducing the potential for damage caused by standing water, such as leaks or mold growth.

The other options indicate steeper slopes, which can lead to rapid water movement, potentially causing splash back or inadequate drainage if not properly managed. A flatter slope, like 1 inch in 14 feet or 1 inch in 12 feet, could become less effective in directing water, while the 1 inch in 10 feet slope might create excessive velocity leading to erosion or overflow beyond the gutter's capacity. Therefore, the 1 inch in 16 feet slope strikes a balance between effective drainage and structural integrity.
