How to Choose the Right Grade of Cedar Shakes for Auburn’s Climate

For any homeowners in Auburn, the architectural charm of a cedar shake roof is unmatched. It provides a natural, rustic elegance that complements the wooded landscapes and historic neighborhoods throughout the Plains. However, choosing cedar is not just an aesthetic decision: it is a technical one. Cedar is a living, organic material that reacts to its environment. In a climate like East Alabama, where high humidity, intense summer heat, and heavy seasonal rains are the norm, selecting the correct grade of wood is the difference between a roof that lasts thirty years and one that fails in ten.

When you begin researching cedar roofing, you will quickly encounter terms like "Heavy Shakes," "Perfections," "Blue Label," and "100% Edge Grain." These classifications are not just marketing jargon. They represent the physical integrity of the wood and how it will stand up to the specific weathering patterns of the Auburn area. Because cedar naturally expands and contracts with moisture, the way the wood is cut determines how much it will warp, twist, or split over time.

This guide is designed to help Auburn homeowners navigate the complexities of cedar grading. By understanding the diagnostic differences between wood types and how our local climate impacts organic roofing materials, you can ensure your investment remains both beautiful and functional for decades.

Understanding the Grading System: The Blue Label Standard

The premier standard for cedar shakes is established by the Cedar Shake and Shingle Bureau. For a permanent residential structure, you should almost exclusively look for "No. 1 Grade" or "Blue Label" cedar.

In the roofing industry, a Blue Label signifies that the shake is 100% heartwood, 100% edge grain, and 100% clear. To understand why this matters for your home, we have to look at the anatomy of the cedar tree. Heartwood is the dense, inner portion of the tree that contains natural preservatives and oils, making it resistant to decay and insects. Sapwood, the outer layer, lacks these protections and will rot quickly when exposed to the Alabama elements.

The "edge grain" refers to how the wood is cut relative to the tree's rings. Edge grain wood is cut perpendicular to the rings, which creates a stable board that resists "cupping" or curling as it dries. In contrast, "flat grain" wood is cut parallel to the rings. While flat grain is often cheaper, it is highly prone to warping. In a high-humidity environment like Auburn, flat grain shakes will eventually curl upward, allowing wind-blown rain to drive underneath the courses and cause leaks.

Shakes vs. Shingles: Which is Better for East Alabama?

While people often use the terms interchangeably, shakes and shingles are distinct products with different performance profiles.

• Cedar Shingles: Shingles are sawn on both sides, giving them a uniform thickness and a tailored, smooth appearance. They are thinner than shakes and offer a more precise, geometric look. While beautiful, shingles may not provide the same level of shadow line or heavy-duty protection against the occasional hail or heavy storm debris we see in Lee County.
• Cedar Shakes: Shakes are typically thicker and provide a more textured, "split" look. For an Auburn home, "Heavy Shakes" (typically 3/4 inch to 1 inch thick at the butt) offer superior insulation and a much longer lifespan against the UV degradation caused by our intense southern sun. The extra mass of a heavy shake allows it to weather the elements more gracefully than a thin shingle.

Climate Considerations: The Auburn Moisture Factor

Auburn sits in a humid subtropical climate. This means your roof spends a significant portion of the year damp. Moisture is the primary catalyst for fungal growth, moss, and wood rot.

If you choose a lower grade of cedar, such as "Red Label" or "Black Label," you are inviting trouble. These lower grades allow for a percentage of flat grain and sapwood. In our climate, those pieces will act like sponges. They will hold moisture against the roof deck, leading to premature rot. Furthermore, because Auburn has a high density of mature trees, organic debris like pine needles and oak leaves frequently land on roofs.

 In the Southeast, we highly recommend CCA (Chromated Copper Arsenate) treated cedar. This factory-applied treatment deeply penetrates the wood fibers, providing an extra layer of defense against the rot and mildew that thrive in the Alabama heat.

Real-World Examples in Auburn Neighborhoods

Imagine a home in the Northpointe or Grove Hill area. These neighborhoods often feature homes with steep gables and complex rooflines that are perfect candidates for cedar.

A homeowner who chooses a "taper-sawn" shake that is 100% edge grain will see their roof age into a beautiful, uniform silver-grey. Even after a decade of Alabama thunderstorms, the shakes will lie flat and tight against the roof. Conversely, a homeowner who attempts to save costs by using a "contractor grade" bundle will notice visible changes within just three to five years. The edges of the shakes will begin to lift, a phenomenon known as "curling." Once a shake curls, it is no longer shedding water effectively.

Cost Considerations: Value Over Price (2026 Estimates)

Cedar is a premium roofing material, and the initial investment reflects that. In 2026, a high-quality Blue Label cedar shake roof can cost significantly more than standard architectural shingles.

• Initial Cost: Heavy shakes and 100% edge grain wood are more expensive per square due to the manufacturing process and wood quality.
• Maintenance Cost: Cedar requires periodic cleaning and debris removal to prevent rot. You can find specialized support through our Roof Repair and Maintenance for Premium Materials services.
• Lifecycle Value: A properly graded and installed cedar roof adds significant resale value and curb appeal to an Auburn property.

If you choose a lower-grade wood to save 20% on the initial installation, you will likely spend that savings on repairs and premature replacement within fifteen years. In the world of cedar roofing, you truly get what you pay for.

When to Call a Professional

Cedar roofing is a specialty craft. Most standard roofing crews are accustomed to nailing down asphalt shingles, but cedar requires specific nailing patterns, specialized flashing techniques, and an understanding of wood expansion gaps. You should consult a specialist if:

• You notice cracks or "splits" that go all the way through a shake.
• There is a significant buildup of moss or lichen on the north-facing slopes of your roof.
• You see shakes that are severely curled or cupped.
• You want to ensure your wood source is certified Blue Label.

Protecting your home from the unique challenges of the Alabama climate starts with the right materials. A cedar roof is a statement of quality, and when done correctly, it provides a legacy of protection that is as durable as it is beautiful.
