These 10 animal facts will amaze you. A rafter is a type of internal vertical beam that holds up a buildingâs roof load, or weight from above, and constitutes a roofâs framework. Combined with rigid exterior materials such as plywood and shingles, most of these beams are designed to bend slightly under the weight of external forces.
In basic gable roof framing, rafters slope upward from the tops of the building's exterior walls and meet at the roof's peak, or ridge. The ridge board is a horizontal timber that serves as a nailing surface for the upper ends of the rafters but in most gable roofs does not bear any of the roof's weight.
