Answer :
Barge rafters are typically one size wider than common rafters.
Explanation:
1. Common rafters are the primary rafters used to form the slope of a roof, extending from the ridge to the top plate of the exterior wall.
2. Barge rafters, on the other hand, are located at the gable end of a roof and provide support to the roof's edge.
3. Barge rafters are usually wider than common rafters to accommodate the additional overhang at the edge of the roof.
4. This difference in size allows barge rafters to extend past the exterior wall, creating the gable overhang or eaves of the roof.
Therefore, barge rafters are generally one size wider than common rafters to fulfill their specific structural role in the roof's design.
