The primary purpose of an eave cant in roofing is to establish slope for the remaining courses. An eave cant is a triangular-shaped piece, typically made from materials like wood or foam, installed at the eave of the roof. Its design allows for proper drainage and helps to direct water away from the roof and into the gutters.

By creating a slope, the eave cant ensures that water can flow freely instead of pooling in certain areas, which can lead to water damage and leaks. This slope is critical for the overall performance of the roofing system, as it impacts drainage efficiency and helps maintain the longevity of the roofing materials used.

While preventing water pooling and enhancing aesthetic appeal are important factors in roofing design, the eave cant's primary role revolves around establishing the necessary slope to support effective drainage. Insulation is generally addressed through other means, such as insulation materials placed within the attic space or in conjunction with the roofing system itself.
