What type of joint is used to connect rafters at the ridge in roofing?

The appropriate joint used to connect rafters at the ridge in roofing is a lap joint. This type of joint is created by overlapping the ends of two rafters, thereby providing a strong connection that can support the weight and strain from the roofing structure. Lap joints are particularly beneficial in this application because they allow for better load distribution and structural integrity.

In roofing, particularly at the ridge where the rafters meet, a lap joint offers the advantage of increasing the surface area of contact between the two members, which enhances strength and stability. The overlapping nature of the joint helps to resist forces acting on the roof, such as wind or snow load, making it a preferred choice among builders and carpenters when forming a strong connection at the peak of the roof.

Other types of joints, while used in different contexts, would not provide the same level of durability and strength needed for rafter connections at the ridge.
