Rafters are installed piece-by-piece during the construction of the roof. They join at the peak of the roof by connecting to the opposing rafter or to a ridge beam that runs the length of the peak of the house or shed. Rafters are beams that run from the peak of the roof to the top plate of the supporting walls. Let’s begin by comparing these two different roof styles.
