Cedar Shake Shingles: A Comprehensive Guide

Cedar shake shingles offer a timeless aesthetic and natural durability that few other roofing materials can match. Their rustic charm and inherent resistance to the elements have made them a popular choice for homeowners seeking both beauty and longevity in their roofing system. This comprehensive guide will delve into every aspect of cedar shake shingles, from their manufacturing process and installation techniques to their maintenance requirements and cost considerations. Whether you’re considering a new roof or simply curious about this classic roofing material, this guide will provide you with the knowledge you need to make an informed decision.

What are Cedar Shake Shingles?

Cedar shake shingles are roofing materials made from split logs of cedar trees. Unlike cedar shingles, which are sawn, cedar shakes are hand-split or machine-split, resulting in a thicker, more irregular appearance. This rustic texture is one of the primary reasons homeowners choose cedar shakes; they offer a distinctive and natural look that enhances the curb appeal of any home.

Types of Cedar Shake Shingles

While all cedar shakes share a common origin, there are several variations in their cut, size, and treatment. Understanding these differences is crucial when selecting the right cedar shake for your roofing project.

Hand-Split and Re-Sawn Shakes

These shakes are hand-split from cedar logs, then sawn on one side to create a smoother surface. The split face retains the natural texture of the wood, while the sawn back ensures a consistent thickness for easier installation. Hand-split and re-sawn shakes offer a good balance between rustic aesthetics and ease of installation.

Tapersawn Shakes

Tapersawn shakes are sawn on both sides, creating a consistent taper from butt to tip. This results in a more uniform appearance compared to hand-split shakes. While they lack the rugged texture of hand-split shakes, tapersawn shakes offer a cleaner, more refined look that may be preferred for certain architectural styles.

Heavy Split and Resawn Shakes

As the name suggests, these shakes are thicker and more substantial than standard hand-split and re-sawn shakes. Their increased thickness provides enhanced durability and a more pronounced rustic appearance. They are often used in areas with harsh weather conditions or where a particularly robust roofing system is desired.

Cedar Species Used for Shakes

The type of cedar used to manufacture shakes significantly impacts their durability, color, and overall performance. Western Red Cedar is the most common and highly regarded species for cedar shake shingles due to its natural resistance to decay, insects, and moisture.

Western Red Cedar

Western Red Cedar is renowned for its exceptional durability and natural beauty. Its heartwood contains natural oils that act as preservatives, protecting the wood from rot, decay, and insect infestation. Western Red Cedar shakes also exhibit excellent dimensional stability, meaning they are less prone to warping or cracking than shakes made from other wood species. Its reddish-brown hue weathers beautifully over time, developing a silvery-gray patina that adds to its character.

Alaskan Yellow Cedar

Alaskan Yellow Cedar is another durable and rot-resistant option, although it is less commonly used for shakes than Western Red Cedar. It has a lighter, yellowish color and a finer grain. While not as readily available, it offers a good alternative with similar performance characteristics.

Benefits of Choosing Cedar Shake Shingles

Cedar shake shingles offer a multitude of advantages that make them a compelling choice for homeowners. From their aesthetic appeal to their environmental benefits, cedar shakes provide a unique combination of form and function.

Aesthetic Appeal

The natural beauty of cedar shakes is undeniable. Their rustic texture, warm color tones, and unique grain patterns create a visually appealing roof that complements a wide range of architectural styles. Whether you’re aiming for a traditional, country-style look or a more modern, contemporary aesthetic, cedar shakes can enhance the curb appeal of your home.

Durability and Longevity

When properly installed and maintained, cedar shake shingles can last for 30 to 50 years, or even longer in some cases. Their natural resistance to decay, insects, and moisture contributes to their exceptional longevity. The thickness of cedar shakes also provides excellent protection against hail, wind, and other weather-related damage.

Natural Insulation

Cedar shakes offer natural insulation properties that can help reduce energy costs. The wood fibers trap air, creating a barrier against heat transfer in the summer and heat loss in the winter. This can lead to lower heating and cooling bills, as well as a more comfortable indoor environment.

Environmental Friendliness

Cedar is a renewable resource, and cedar shakes are manufactured using relatively low-impact processes. When sustainably harvested, cedar forests can provide a continuous supply of roofing materials. Cedar shakes are also biodegradable, meaning they will decompose naturally at the end of their lifespan, unlike synthetic roofing materials that contribute to landfill waste.

Wind and Impact Resistance

Cedar shakes are known for their ability to withstand high winds and impact from hail or falling debris. Their thickness and density provide a robust barrier against the elements, protecting your home from damage. In areas prone to severe weather, cedar shakes can offer a significant advantage over lighter roofing materials.

Installation of Cedar Shake Shingles

Proper installation is crucial to ensure the long-term performance and durability of cedar shake shingles. It’s highly recommended to hire a qualified roofing contractor with experience in cedar shake installation. This section provides an overview of the key steps involved in the installation process.

Underlayment

Before installing the cedar shakes, a layer of underlayment is applied to the roof deck. The underlayment serves as a waterproof barrier, protecting the roof deck from moisture that may penetrate the shakes. Synthetic underlayment is generally preferred over traditional felt paper due to its superior durability and water resistance.

Interlayment (Optional but Recommended)

For added protection, an interlayment layer can be installed between each course of cedar shakes. The interlayment helps to shed water more effectively and provides an extra layer of defense against leaks. This is particularly recommended in areas with heavy rainfall or snow.

Spacing and Overlap

Proper spacing and overlap are essential for ensuring a watertight and durable roof. The shakes are typically installed with a specific exposure, which is the amount of the shake that is visible. The exposure depends on the length of the shake and the desired aesthetic. The shakes should also be properly staggered to prevent vertical seams from aligning, which could create weak points in the roof.

Fasteners

The shakes are secured to the roof deck using corrosion-resistant fasteners, such as stainless steel nails or staples. The fasteners should be long enough to penetrate the roof deck securely and should be driven straight to avoid damaging the shakes. It’s important to use the correct type and size of fasteners recommended by the shake manufacturer.

Ridge and Hip Detailing

The ridge and hip of the roof require special attention to ensure a watertight and aesthetically pleasing finish. Cedar ridge caps and hip caps are typically used to cover these areas, providing a seamless transition between the roof planes. These caps are often made from the same cedar material as the shakes, creating a cohesive look.

Ventilation

Proper roof ventilation is crucial for preventing moisture buildup and extending the lifespan of the cedar shakes. Adequate ventilation allows air to circulate beneath the roof deck, helping to dry out any moisture that may accumulate. This can prevent rot, mold, and other moisture-related problems.

Maintaining Cedar Shake Shingles

While cedar shakes are naturally durable, regular maintenance is essential to ensure their long-term performance and aesthetic appeal. Proper maintenance can prevent problems such as rot, moss growth, and splitting, extending the lifespan of your roof.

Regular Inspections

It’s recommended to inspect your cedar shake roof at least once a year, preferably in the spring and fall. Look for signs of damage, such as cracked, split, or missing shakes. Also, check for moss or algae growth, which can trap moisture and accelerate decay.

Cleaning

Remove any debris, such as leaves, twigs, and pine needles, from the roof regularly. This debris can trap moisture and create a breeding ground for moss and algae. You can use a soft brush or a leaf blower to remove debris. Avoid using a pressure washer, as it can damage the shakes.

Moss and Algae Removal

Moss and algae growth can be a common problem on cedar shake roofs, especially in damp or shady areas. There are several methods for removing moss and algae, including using a brush, applying a chemical treatment, or installing zinc or copper strips along the ridge of the roof. Zinc and copper strips release ions that inhibit the growth of moss and algae.

Treatment with Preservatives

Applying a wood preservative can help protect the cedar shakes from rot, decay, and insect infestation. There are several types of wood preservatives available, including oil-based, water-based, and borate-based preservatives. Choose a preservative that is specifically designed for use on cedar shakes and follow the manufacturer’s instructions carefully.

Replacing Damaged Shakes

If you find any damaged shakes during your inspections, it’s important to replace them promptly. Damaged shakes can allow water to penetrate the roof deck, leading to leaks and other problems. Replacing a shake involves removing the old shake, inserting a new shake, and securing it with fasteners.

Cost of Cedar Shake Shingles

The cost of cedar shake shingles can vary depending on several factors, including the type of cedar, the grade of the shakes, the complexity of the roof, and the location of your home. While cedar shakes are generally more expensive than asphalt shingles, their longevity and aesthetic appeal can make them a worthwhile investment.

Material Costs

The cost of the cedar shakes themselves can range from $8 to $15 per square foot, depending on the type and grade of the shakes. Premium-grade shakes, such as those made from Western Red Cedar heartwood, will typically cost more than lower-grade shakes. Hand-split shakes may also be more expensive than tapersawn shakes due to the increased labor involved in their production.

Installation Costs

Installation costs can vary depending on the complexity of the roof, the experience of the contractor, and the local labor rates. Expect to pay between $8 and $18 per square foot for professional installation. Complex roofs with many angles and dormers will typically cost more to install than simple, straightforward roofs.

Total Costs

The total cost of a cedar shake roof can range from $16 to $33 per square foot, including materials and installation. While this is a significant investment, it’s important to consider the long-term benefits of cedar shakes, such as their durability, longevity, and aesthetic appeal. A well-maintained cedar shake roof can add significant value to your home.
