Wood Shingle/Shake (Scalloped): A Comprehensive Guide for Homeowners

Wood shingles and shakes offer a classic, textured look that enhances curb appeal while providing durable roofing or siding options. The scalloped variation adds a distinctive decorative edge, creating a unique silhouette on facades and rooflines. This article explores definition, materials, installation, maintenance, and cost considerations to help homeowners make informed decisions about wood shingle and shake applications.

What Are Wood Shingles And Shakes

Wood shingles are thin, tapered pieces of wood installed in overlapping rows to shed water. Wood shakes are thicker, split or hewn on one or both sides, resulting in a rougher surface and more pronounced texture. Scalloped wood shingle/shake refers to edges that are curved or stepped to form a decorative, curved pattern along the board edge. This design detail can accentuate rooflines, gables, or siding borders.

When comparing shingle vs shake, consider appearance, weight, and installation technique. Shingles yield a uniform, smooth finish, while shakes offer rustic charm and better air movement beneath the surface. Scalloped edges amplify visual interest but may require careful maintenance to preserve the curved profile.

Materials And Grades

Common wood choices include cedar, redwood, pine, and fir. Cedar is favored for its natural rot resistance and dimensional stability, though higher in cost. Redwood provides excellent decay resistance but can be more brittle in extreme climates. Pine and fir are more affordable but may require protective treatments and more frequent maintenance.

Grades refer to clearness and defects. Clear grades have minimal knots and consistent grain, offering a cleaner look suitable for upscale projects. Common grades allow more character with knots and variations, which can complement a rustic or traditional aesthetic. The scalloped edge can be applied to various wood types, but cedar remains the most prevalent due to its longevity and workability.

Installation Overview

Wood shingles and shakes are typically installed over a solid roof deck or siding substrate with proper nailing and overlapping patterns. Ventilation and moisture control are crucial to prevent rot. Scalloped details require precise cutting and routing to maintain symmetry along the edge. The installation sequence generally includes:

• Preparing a clean, dry substrate with appropriate underlayment or felt.
• Installing starter courses aligned with the scalloped edge to ensure an even outline.
• Applying shingles or shakes in offset, overlapping rows to shed water and reduce gaps.
• Carefully shaping and securing scalloped edge components for a consistent finish.
• Sealing ends or edges with paint, stain, or sealant designed for exterior wood.

Professional installation is recommended for scalloped patterns, as improper alignment can lead to water ingress, edge lifting, or uneven appearance. Regular inspections during the first year help identify lapses or gaps that could compromise performance.

Maintenance And Longevity

Proper maintenance extends the life of wood shingles and shakes. Key practices include:

• Regular cleaning to remove debris that traps moisture and promotes mold growth.
• Cederal treatment or sealant reapplication on cedar or redwood to preserve rot resistance and color.
• Periodic inspection for cracks, warping, or insect damage, especially after severe weather.
• Prompt replacement of damaged shingles or shakes to prevent cascading deterioration.
• Protective measures such as overhangs and gutters to direct water away from edges and scalloped profiles.

With proper care, cedar wood shingles or shakes can last 30 to 50 years or more, depending on climate, maintenance, and installation quality. Scalloped edges may require more frequent refreshment of sealants due to exposure along curves and joints.

Common Problems And Troubleshooting

Owners may encounter several typical issues with wood shingles and shakes, particularly the scalloped variety:

• Moisture infiltration at scalloped seams leading to rot or mold if not properly sealed.
• Warping or cupping from uneven moisture exposure or poor ventilation.
• Insect damage, such as beetles or termites, especially in regions with higher pest activity.
• Fading or discoloration from sun exposure; cedar often takes stain well but may require reapplication after 5–10 years.
• Cracking or splitting in harsh climates or when boards experience rapid temperature shifts.

Address issues promptly by replacing damaged pieces, resealing surfaces, and verifying ventilation and drainage. Preventive maintenance reduces the risk of major repairs and preserves the scalloped aesthetic.

Environmental Impact And Sustainability

Wood shingles and shakes can be a sustainable option when sourced responsibly. Look for products labeled as FSC-certified or from mills that practice responsible forestry. Cedar and redwood offer natural rot resistance, potentially reducing the need for chemical treatments, though some installations still require finishes for longevity. Reclaimed wood options can minimize environmental impact while adding character. Proper disposal and recycling of old materials at end of life contribute to a greener building approach.

Choosing A Contractor And Materials

Selecting a qualified contractor is essential for successful wood shingle and shake projects, especially with scalloped patterns. Consider these criteria:

• Experience with installation of wood shingles, shakes, and scalloped edges.
• Evidence of past projects featuring scalloped work and reliable references.
• Knowledge of ventilation, underlayment, and moisture management specific to wood systems.
• Recommendations for wood species, thickness, and finish suitable for local climate.
• Clear written estimates detailing materials, labor, warranty terms, and maintenance requirements.

Material considerations influence performance. Cedar remains a popular choice for its balance of durability and workability, but redwood and select pine options may suit certain budgets or aesthetics. Finish choices include transparent stains to highlight grain or solid stains for color cohesion, with UV protection and water repellence being important factors.

Cost Considerations And Practical Tips

Costs for wood shingles and shakes vary by material, scalloped complexity, climate, and labor. Cedar shingles typically cost more than standard asphalt shingles but may offer longer life and enhanced curb appeal. Scalloped applications add labor time, increasing total project cost. Budgeting considerations:

• Material costs per square foot, including delivery and waste allowances.
• Labor rates for skilled carpentry and scalloped shaping.
• Protection and maintenance costs, including sealants and periodic re-finishing.
• Potential premium for custom scalloped profiles compared to flat edges.

For homeowners, it is beneficial to obtain multiple bids and request a detailed breakdown. Ask about climate-specific maintenance plans, warranty coverage on materials and workmanship, and recommended re-sealing intervals. A well-chosen finish and regular upkeep can maximize performance and preserve the scalloped aesthetic for decades.
