A rafter is defined as one of a series of sloped structural pieces (typically wooden beams) that extend from the hip or ridge to eave, wall plate, or downslope perimeter. They’re designed to support the roof deck, shingles, and everything else that goes with the roof. Rafters are the traditional way to frame a roof.
What Is Roof Rafter?
A roof rafter is a beam that supports the roof. It is usually made of wood, but can also be made of steel or concrete. The rafters are placed at regular intervals along the length of the roof, and are tied together at the ridge beam.
The pitch of the roof is determined by the length of the rafters. The longer the rafter, the steeper the pitch. Roof rafters are typically made of 2–by–4 lumber, but may be made of 2–by–6, 2–by–8, or 2–by–10 lumber if the span is great enough.
The most common type of roof rafter is the collar tie. This is a rafter that is placed at the collar beam, which is the beam that runs along the length of the roof at the top of the rafters.
The collar tie helps to distribute the weight of the roof evenly across the rafters. The other type of roof rafter is the king post. This is a single rafter that is placed in the center of the roof.
It is used to support the ridge beam, and is usually made of heavier lumber than the collar tie. The roof rafters are connected to the top
