What is a roofing requirement for cedar shakes?

Cedar shakes are a popular roofing material known for their durability and aesthetic appeal. The requirement for cedar shakes to be used on pitches of 4:12 or steeper stems from both performance and aesthetic considerations. When installed on a slope of this degree or steeper, cedar shakes can effectively shed water, reducing the risk of leaks and water damage. This pitch allows the water to flow off the shingles quickly, preventing water from pooling and promoting better ventilation under the roof.

Using cedar shakes on low-pitched roofs (below 4:12) can lead to complications. The angle may not allow for proper drainage, which can cause water to sit on the roof longer and increase the potential for moisture damage or degradation of the roofing material over time. Consequently, adhering to the guideline of using cedar shakes primarily on pitches of 4:12 or steeper helps ensure the longevity and effectiveness of the roofing system while maintaining its aesthetic appeal.
