Cedar Shingles: A Comprehensive Guide to Benefits, Types, and Maintenance

Cedar shingles are a classic roofing and siding material prized for natural beauty, durability, and a distinctive scent. This guide explains what cedar shingles are, the differences between shingles and shakes, common types, installation considerations, maintenance needs, and cost implications. Readers will gain a clear understanding of how cedar shingles perform in U.S. climates and how to choose the best option for a home.

What Are Cedar Shingles?

Cedar shingles are thin, flat pieces of wood cut from cedar logs, typically western red cedar or eastern red cedar, used as roof coverings or exterior siding. They are designed to lay in overlapping courses, creating a weather-resistant barrier while showcasing the wood’s natural grain and color. Cedar’s natural oils help resist decay and repel insects, contributing to a longer service life when properly installed and maintained.

Key distinctions include the orientation (roof shingles vs. siding shingles) and the cut style. Shingles are usually sawn on both faces for a smooth, uniform appearance, while shakes are split or half-rounded and can have a more rustic texture. The term “cedar shingles” is sometimes used interchangeably with “cedar shakes,” but technically they differ in manufacturing and surface texture.

Types Of Cedar Shingles

The two primary cut styles for cedar shingles are sawn (smooth) and cleft (split). Each style offers a distinct look and performance characteristics.

• Sawn Cedar Shingles: Cut on both sides for a smooth, uniform surface. They provide a clean, refined appearance and a tight grain that paints evenly if used as siding rather than roofing. Sawn shingles are popular for modern or traditional exterior applications.
• Cleft Cedar Shingles (Shakes): Split from a log, displaying a rougher texture with a more rustic charm. They tend to shed water slightly differently and may require more careful installation to achieve a tight seal. This style is common for rustic or historic-inspired exteriors.
• Thickness And Profile: Cedar shingles come in standard thicknesses (commonly around 3/8 to 1/2 inch). Profiles range from straight-edged to beveled, influencing shadow lines and ventilation. Roof installations often use thicker shingles to improve durability and weather resistance.
• Grade And Species: Western red cedar is the most widely used for its rot resistance and pleasant aroma. Other species like Alaska yellow cedar or northern white cedar are less common but offer different color tones and durability.

Benefits Of Cedar Shingles

Natural Beauty and a warm, amber-to-red patina that ages gracefully is a primary draw. Cedar’s grain and color shifts add character over time, which can boost curb appeal and home value.

Durability And Weather Resistance Cedar contains natural oils that resist decay and insect damage, helping it endure in varying U.S. climates. Proper nailing patterns, ventilation, and maintenance extend its life in regions with humidity, heavy rainfall, or snow.

Insulation And Breathability The wood’s natural cellular structure provides insulation benefits and allows the structure to breathe, reducing the risk of moisture buildup when installed with correct underlayment and ventilation.

Lightweight And Easy To Work With Compared to many roofing materials, cedar shingles are relatively light, aiding in handling and reducing structural load. They can be cut and shaped on site, offering design flexibility for custom projects.

Drawbacks And Considerations

While cedar shingles offer many advantages, several considerations should guide the decision.

• Maintenance Needs: Cedar requires periodic cleaning, staining or sealing, and inspections to prevent moisture damage, fading, and surface checking. Neglect can shorten its life.
• Cost: Cedar shingles generally cost more than asphalt shingles or some composite options, both in materials and installation. Long-term maintenance adds to ongoing expenses.
• Durability Variability: Exposure to harsh climates, constant moisture, or poor ventilation can lead to cupping, curling, or rot if not properly installed and maintained.
• Fire Considerations: Depending on local codes and home use, cedar is a Class C or treated wood option in some locales; fire-rated treatments or alternative materials may be necessary in high-risk areas.

Installation Overview

Proper installation is crucial to performance and longevity. A qualified contractor should handle roofing or siding projects. Key factors include ventilation, underlayment, nailing pattern, and spacing to accommodate wood expansion and contraction.

• Roof Installations: Cedar shingles are typically installed over a solid roof deck with a suitable underlayment. A continuous eave overhang and ridge ventilation help curb moisture buildup and heat.
• Siding Installations: Cedar shingles on siding require a water-resistive barrier, furring strips for ventilation, and proper flashing around windows, doors, and penetrations to prevent water intrusion.
• Maintenance Access: Design choices should allow easy cleaning and inspection, with accessible gutters, drip edges, and clean transitions at joints.

Maintenance And Care

Regular maintenance preserves cedar shingles’ appearance and performance. A proactive approach typically includes cleaning, sealing, and periodic inspections.

• Cleaning: Remove debris and moss to maintain moisture balance. Gentle washing with low-pressure water and a mild detergent is commonly recommended.
• Sealing And Staining: Apply a high-quality, breathable sealer or stain every 3–5 years (timing depends on climate and exposure). Reapply when color fades or gray patina develops.
• Inspection: Look for cupping, warping, or signs of rot, and address issues promptly. Ensure proper ventilation and avoid prolonged moisture exposure in shade-rich areas.
• Repair: Replace damaged shingles promptly to prevent leaks. Use matching cedar species and thickness for consistency.

Durability, Lifespan, And Regional Considerations

In the United States, cedar shingles commonly last 20–40 years depending on climate, installation quality, and maintenance. Regions with high humidity, heavy rainfall, or insect activity may experience shorter lifespans without diligent upkeep. In colder climates with freeze-thaw cycles, proper installation and ventilation are critical to minimize movement that can lead to cracking.

Environmental factors, such as sun exposure and pollution, influence color fading and surface checking. Homeowners in coastal areas should consider rot resistance and potential salt exposure, while inland regions with dry heat may benefit from sealants that reduce surface drying and cracking.

Cost Considerations

Cost for cedar shingles includes materials, installation, and ongoing maintenance. Materials typically range from $5 to $15 per square foot for shingles alone, with installation bringing total costs to $8 to $20 per square foot for roofing. Siding projects may range similarly, depending on profiles and underlayment requirements.

Long-term value comes from curb appeal, potential energy savings due to natural insulation, and a lifespan that can outlast some alternatives when properly cared for. Budget for periodic staining and sealing to preserve color and protection against moisture.

Environmental And Aesthetic Considerations

Many homeowners value cedar for its renewable source, biodegradability, and reduced environmental footprint compared with some synthetic materials. Look for sustainably harvested cedar with certifications from programs such as the Forest Stewardship Council (FSC). Aesthetic options include selecting species and grades that align with home design goals, whether aiming for a traditional, rustic, or modern look.

Comparing Cedar Shingles To Cedar Shakes

To avoid confusion, understand how shingles differ from shakes. Shingles are sawn, offering uniform surfaces and consistent edges. Shakes are split, resulting in a more textured surface and rustic appearance. Shakes can provide faster water shedding but may require more maintenance to prevent moisture ingress. Both options use cedar and share similar regional considerations, but their texture, installation methods, and maintenance needs vary.

Choosing The Right Cedar Shingles

Owners should evaluate climate, architectural style, maintenance willingness, and budget. For roofs in wet climates, ensure proper ventilation and underlayment, and plan for routine inspections. For siding, consider shading patterns, color retention, and the desired surface texture. Consulting with a licensed contractor ensures correct nailing patterns, gap allowances, and flashing details to maximize performance.
