Wood Shake Roofing Shingles: A Comprehensive Guide to Pros, Cons, and Installation

Wood shake roofing shingles offer a natural, textured look that enhances many American homes. This guide explores the types, benefits, drawbacks, installation considerations, maintenance needs, and cost factors to help homeowners decide if wood shakes are right for their roof. Readers will learn how to compare cedar shakes with other wood options, what to expect from installation, and how to maximize longevity and performance.

Overview

Wood shake roofing shingles are a rustic-grade roofing material crafted from broad-shouldered lumber pieces, typically cedar. Unlike smooth-sawn shingles, shakes have a rougher surface and varied thickness, creating a dimensional, shadowed appearance. The appeal lies in aesthetics, insulating properties, and a natural aging process that develops a silver-gray patina over time. Performance depends on species, grade, factory treatments, and proper installation. Homeowners should weigh climate, fire codes, and maintenance capacity when considering wood shakes as a primary roofing material.

Types And Characteristics

Common options include:

• Cedar Shakes: The most popular choice, prized for durability and natural rot resistance. Western red cedar and Alaska yellow cedar are common varieties.
• Shingles Versus Shakes: Shingles are sawn and uniform; shakes are split and rough. Shakes provide a more textured look but can be more prone to weathering if not properly installed.
• Factory-Treated And Fire-Resistant Options: Some products receive fire-retardant or preservative treatments. Keep in mind treatment can affect color and warrantied performance.
• Other Conifer Shakes: Redwood and southern yellow pine shakes are less common but available in certain markets.

Pros And Cons

Understanding the advantages and drawbacks helps in decision-making:

• Aesthetic Appeal: Rich texture and color variation create architectural character that complements traditional and rustic designs.
• Insulation And Sound: Wood shakes provide natural insulation and a softer roof surface, which some homeowners find advantageous.
• Longevity With Proper Care: When properly installed and maintained, cedar shakes can last several decades, often 30 to 50 years depending on climate and maintenance.
• Maintenance Intensity: Regular inspections, moss and lichen control, and periodic re-sealing or staining may be required to preserve appearance and performance.
• Fire Considerations: Untreated wood is combustible. Fire-resistant coatings or treatments can reduce risk but may affect warranty or color.
• Cost: Materials and installation typically cost more upfront than asphalt shingles, with wide variability by region and roof complexity.

Materials, Quality, And Performance

Quality factors influence durability and warranty outcomes. Key considerations include:

• Wood Species And Grade: Cedar is favored for rot resistance and stability; select heartwood when possible to improve longevity.
• Cut Type: Hand-split shakes offer character but may have variable thickness; machine-split or sawn shingles yield more uniform performance.
• Underlayment And Deck Condition: A solid roof deck with proper underlayment is essential to prevent moisture intrusion and extend life.
• Ventilation: Adequate attic ventilation reduces moisture buildup and wood void damage during temperature swings.

Installation Considerations

Successful installation minimizes water intrusion and wind uplift. Important steps include:

• Roof Deck Preparation: Inspect and repair damaged boards; ensure a clean, dry surface before installing underlayment.
• Underlayment: High-quality asphalt or synthetic underlayment provides a secondary barrier against moisture.
• Fasteners: Use corrosion-resistant, corrosion-rated nails; spacing and nailing patterns must align with manufacturer guidelines and climate exposure.
• Ventilation And Clearance: Maintain proper roof clearance around chimneys, vents, and skylights to prevent moisture trappage and debris buildup.
• Pattern And Alignment: Start from the bottom edge and work upward, staggering joints for optimal water shedding and wind resistance.

Maintenance And Longevity

Proactive maintenance extends life and preserves appearance. Recommended practices include:

• Regular Inspections: Check for cracked, split, or cupped shakes after severe weather; replace damaged pieces promptly.
• Moss And Algae Control: In damp climates, remove moss and consider zinc or copper strips to inhibit growth; treat mold promptly.
• Cleaning: Gently remove debris; avoid power washing that can damage fibers.
• Staining And Sealing: Periodic resealing or staining may be advised by manufacturers to maintain color and resistance, typically every 3–10 years depending on climate and product.
• Roof Slope And Drainage: Ensure adequate slope for shedding water; poor drainage accelerates decay.

Cost And Lifespan

Costs vary by region, roof complexity, and product choice. On average, homeowners might see:

• Material Cost: Cedar shakes generally cost more per square foot than composite or asphalt options, with wide regional variation.
• Installation: Labor-intensive installation raises overall project cost; expect higher quotes for steeper pitches or complex rooflines.
• Lifespan: With proper maintenance, cedar shakes commonly last 30–50 years; some installations exceed 50 years with ideal conditions.
• Cost Considerations: Include underlayment, ventilation improvements, potential roof deck repairs, and periodic staining or sealing in the total budget.

Environmental Impact And Sustainability

Wood shakes are a renewable roofing option when sourced responsibly. Key points include:

• Sustainable Sourcing: Look for certifications like FSC or SFI to ensure sustainable harvesting practices.
• Biodegradability: Wood is biodegradable, reducing end-of-life waste compared with some synthetic alternatives.
• Maintenance And Emissions: Ongoing maintenance reduces the risk of failures that could necessitate early replacement, supporting longer system life and lower overall environmental impact.
• Treatments: Fire retardants and preservatives improve performance but may introduce chemical considerations; verify compatibility with local codes and homeowner preferences.

Choosing A Contractor And Warranty Considerations

Selecting a qualified contractor ensures proper installation and warranty reliability. Tips include:

• Licensing And Insurance: Verify current licenses and liability coverage; request proof of workers’ compensation.
• Manufacturer Warranties: Review coverage for both materials and installation; understand exclusions related to improper nailing patterns or mixed materials.
• Past Projects: Ask for references and inspect completed roofs to assess workmanship and aging.
• Maintenance Guidance: Choose a contractor who provides a maintenance plan and clear recommendations for inspections and treatments.

FAQs

Frequently asked questions address common concerns:

• Can wood shakes be installed over existing shingles? In most cases, a roof deck inspection is required, and some regions prohibit overlays due to venting or flashing requirements.
• Are cedar shakes more flammable? Untreated cedar is combustible; using approved fire-rated treatments and following code guidelines can reduce risk but may affect warranty.
• How often should cedar shakes be inspected? Annual inspections are recommended, with more frequent checks after severe weather events.
