What is the required pitch for wood shakes and shingles?

The required pitch for wood shakes and shingles typically starts at 4:12. This means that for every 12 horizontal inches, the roof rises at least 4 vertical inches. This pitch is essential because it helps ensure that water drains off the roof effectively, reducing the risk of water pooling and potential leaks underneath the roofing material.

At this pitch, the overlapping design of shakes and shingles can effectively prevent water intrusion, which is critical for maintaining the integrity and longevity of the roof. Lower pitches, like 1:12 or 3:12, do not provide adequate drainage for wood roofing products, which can lead to moisture retention and premature deterioration. Therefore, adhering to the minimum 4:12 pitch requirement is crucial for optimal performance and durability of wood shakes and shingles.
