There’s no fixed pitch for a valley rafter. What is the pitch of a valley rafter? The pitch of a valley rafter depends on the pitch of the roofs it’s connecting.
The angle of valley rafters depends on the pitch of the intersecting roof sections. What is the angle of a 4 12 pitch valley? A 4:12 pitch roof has a slope angle of approximately 18.43 degrees.Īre valley rafters always 45 degrees? No, valley rafters are not always at a 45-degree angle. The angle and dimensions of the valley can vary depending on the specific roof design. How do you calculate roof valleys?
