What is the recommended minimum slope for applying wood shakes to ensure good drainage?

The recommended minimum slope for applying wood shakes is 4-in-12. This slope ensures that water runoff is adequate to prevent water from pooling on the roof surface. A minimum pitch of 4-in-12 means that for every 12 horizontal inches, the roof rises at least 4 inches. This incline allows gravity to effectively channel water down and off the roof, mitigating the risk of leaks and water damage, which are particularly important considerations for wood shakes that can deteriorate if exposed to moisture for prolonged periods.

In roofing practice, steeper pitches are often preferred, but 4-in-12 is generally seen as the minimum to maintain the integrity and lifespan of wood shakes, allowing them to perform effectively under various weather conditions. Other options present different slopes that may not provide adequate drainage for wood shakes, increasing the likelihood of water retention and associated problems.
