A gutter system is described which combines a leaf screen, rain gutter, drip edge and soffit vent into a unitary, molded plastic structure. The gutter system forms the fascia along a roof eaves. The gutter fascia can be molded with a wood grained texture or left smooth, and can be molded of any desired color. Because it is molded from a flexible, plastic material, the gutter can be folded flat, allowing multiple sections to be stacked and packed into a relatively small shipping carton.
