Rake: The inclined edge of a sloped roof over a wall from the eave to the ridge
Rafter: The supporting framing member immediately beneath the deck, sloping from the ridge to the wall plate
Gutter: The trough that channels water from the eaves to the downspouts
Vent: Any outlet for air that protrudes through the roof deck such as a pipe or stack. Any device installed on the roof, gable or soffit for the purpose of ventilating the underside of the roof deck
