Adding an overhang to the gable ends of your shed is a similar process to framing out a new one. Fill in the gable end studs after the rafters are complete photo 11. Sheathe the walls and roof with plywood. Drive 8d nails every 6 in.

Eaves form the overhang to distribute water clear of the walls. An eave is the edge of the roof that overhangs the face of a wall and normally projects beyond the side of a building.

After the end points of the plates are located the length is found using a base 1 triangle for a 6 in 12 pitch where the hypotenuse is 1 118 times the length of the base.

The picture above shows the plan view of a gable roof. Begin by measuring from your extended fascia to the peak of the shed. When you nail in the second boards offset the seams of the upper and lower layers by at least 24 in 61 cm. Use 8 penny nails to attach the first 2 in 4 in 5 1 cm 10 2 cm board to the wall studs.
