Measuring the amount of gutter slope is considered to be not required because standard building codes and practices often do not mandate a specific measurement of slope for gutters. While it is crucial for gutters to have an appropriate slope to ensure proper drainage and to prevent water pooling or overflow, there may not be explicit requirements set forth by the regulations or industry standards that inspectors must adhere to when conducting home inspections.

In practice, homeowners and builders are often encouraged to install gutters with a slight slope (typically 1/4 inch for every 10 feet) towards the downspouts to ensure efficient water flow, but this recommendation does not elevate the task to a mandatory status during inspections. The distinction between what is mandatory versus what is advisable is important, as it reflects a difference between required work and best practices that are beneficial but not enforced.
