A shake roof is a type of roofing made from split wooden shingles, commonly crafted from cedar, redwood, or pine. Unlike traditional shingles, shakes are thicker, more textured, and provide a rustic appearance that appeals to many homeowners. This roofing style combines natural beauty with durable performance, making it popular across various regions in the United States.
| Aspect | Shake Roof |
|---|---|
| Material | Typically cedar, redwood, or pine wood |
| Appearance | Rustic, textured, hand-split look |
| Durability | Long-lasting with proper maintenance (25-40 years) |
| Cost | Higher than asphalt shingles, moderate to high |
| Installation | More labor-intensive than standard shingles |
| Maintenance | Requires regular inspections and upkeep |
Definition and Composition of a Shake Roof
A shake roof consists of wooden roofing shingles that are traditionally hand-split from logs, differing from standard sawn shingles which have a smoother, more uniform finish. The process of splitting creates a rougher surface, which enhances the aesthetic appeal and improves water shedding qualities. Most commonly, cedar is used due to its natural resistance to moisture, decay, and insect damage.
The thickness and texture of shakes contribute to their durability and insulation properties, offering homeowners an effective roofing solution that blends with natural surroundings. These roofs allow for air circulation beneath the shakes, reducing heat buildup in warmer climates.
Materials Commonly Used for Shake Roofs
Shake roofs derive their performance and appearance from the wood types utilized. The most popular choices for shake roofs include:

- Cedar: Renowned for durability, rot resistance, and attractive color variations from light amber to deep reddish-brown.
- Redwood: Valued for its strength and resistance to decay; more costly and less common than cedar.
- Pine: Occasionally used but less durable than cedar or redwood and typically treated to enhance performance.
Each wood type brings distinct characteristics, but cedar remains the dominant material due to its balance of cost, performance, and visual appeal in American roofing.
How Shake Roofs Are Made
Shake roofs are manufactured by splitting logs into thin pieces with a sharp axe or specialized machinery, a process called “riving.” This method produces shakes with an uneven surface and varying thickness, which contributes to their characteristic rustic look.
The typical thickness of a shake is about ⅜ to ⅝ inch—thicker than conventional sawn shingles. This thickness improves durability and allows for better water runoff. After splitting, shakes may be graded based on quality, size, and appearance, with premium grades reserved for architectural or high-end projects.
Appearance and Architectural Appeal
Shake roofs are prized for their natural, textured appearance that adds charm and character to homes. Their irregular shape and rich wood grain patterns create a distinctive look that fits particularly well with Craftsman, Colonial, and rustic architectural styles.
The weathering process also enhances a shake roof’s aesthetic: wooden shakes gradually turn a silver-gray color when exposed to sunlight and rain, creating a desirable aged look that many homeowners find appealing. This natural patina complements outdoor surroundings and landscaping.
Advantages of Shake Roofs
- Durability: With proper installation and maintenance, a shake roof can last 25 to 40 years, offering longevity compared to other roofing materials.
- Insulation: Wood provides natural insulation, helping to regulate indoor temperatures and improve energy efficiency.
- Wind and Impact Resistance: Shake roofs perform well in areas prone to high winds and hail, especially when installed according to industry standards.
- Fire Resistance: When treated with fire retardants, shakes meet fire safety requirements essential for building codes in wildfire-prone regions.
- Eco-Friendly: Made from natural materials and biodegradable, shake roofs are an environmentally sustainable choice.
Challenges and Considerations
Despite their benefits, shake roofs require attentive maintenance and come with certain disadvantages that potential homeowners should consider:
- Higher Cost: Shake roofs generally cost more than asphalt shingles due to material quality and labor-intensive installation.
- Maintenance Needs: Wood roofing demands periodic inspections, cleaning, and treatments to prevent moss, mildew, and insect infestations.
- Potential Fire Risk: Untreated wood shakes pose fire hazards; compliance with fire retardant treatments is critical in many areas.
- Installation Complexity: Skilled roofing contractors with experience in wood shake installation are necessary to ensure performance and longevity.
Installation Process of Shake Roofs
Installing a shake roof requires expertise and several key steps:
- Deck Preparation: The roof deck must be sound, clean, and covered with an underlayment to provide a moisture barrier.
- Shingle Layout: Shakes are installed starting from the roof edge, overlapping to ensure proper water shedding.
- Nailing: Shakes are fastened by hand with corrosion-resistant nails, following specific spacing and placement guidelines.
- Finishing: Ridge caps and flashing are installed to protect vulnerable roof areas.
Proper venting and attention to local building codes further enhance the longevity and safety of a shake roof.

Maintenance Tips to Maximize Shake Roof Lifespan
Regular upkeep helps preserve a shake roof’s functionality and appearance:
- Inspect for damaged or missing shakes every 6 to 12 months, especially after storms.
- Remove moss, algae, and debris to prevent moisture retention and wood decay.
- Apply wood preservatives or fire retardants as recommended by manufacturers.
- Ensure gutters and downspouts are clear to avoid water backup.
- Trim overhanging branches to reduce leaf litter and damage.
Routine maintenance can extend a shake roof’s lifespan and protect the investment in natural wood roofing.
Comparing Shake Roofs to Other Roofing Options
| Type | Durability | Cost | Appearance | Maintenance | Eco-Friendliness |
|---|---|---|---|---|---|
| Shake Roof | 25-40 years | High | Rustic, natural wood texture | High | Very good |
| Asphalt Shingles | 15-25 years | Low | Smooth, uniform color | Low | Moderate |
| Metal Roof | 40-70 years | Moderate to high | Modern, sleek | Low | Good (recyclable) |
| Clay Tiles | 50+ years | High | Traditional, Mediterranean | Moderate | Good |
Environmental and Regional Considerations
Shake roofs perform best in dry to moderate climates where moisture is controlled. Excessive humidity can increase the risk of mold and rot without proper maintenance. As such, regions in the Pacific Northwest, parts of the Northeast, and the upper Midwest may require additional treatments and upkeep.
Additionally, many U.S. building codes require fire-resistant treatments for wooden roofs in wildfire-prone zones, such as California and Colorado, making fire-retardant shakes an essential option in these areas.
Costs and Investment Value
Shake roofs typically cost between $7 and $12 per square foot installed, which is higher than asphalt shingles but lower than some premium materials like slate or clay tiles. The investment is justified by their longevity, energy efficiency, and aesthetic appeal, particularly for homes emphasizing natural style and quality materials.
Insurance and local regulations also impact the total cost. Homeowners may save on energy bills due to wood’s insulating properties but should budget for periodic maintenance and possible treatments.
