A cool, diffuse, high albedo roof (left) which has high IR absorptance at wavelengths across the Planck thermal spectrum for all exit directions compared to an original galvanized lower E, lower albedo finish, smoother, much hotter roof (right), which clearly has a large variation in E(θ) as θ varies (its higher T is fixed).
