Natural cedar shingle siding gives a home a distinctive, textured exterior that can weather to a silvery gray or retain a warmer color with maintenance. Its appearance is only part of the decision: species, shingle grade, installation details, climate, and upkeep all affect performance and cost. This guide explains how cedar shingles work, what buyers should compare, and how to plan a durable installation in the United States.
What Is Natural Cedar Shingle Siding?
Natural cedar shingle siding consists of thin, tapered pieces of wood installed in overlapping courses on exterior walls. The overlap sheds rain while creating the characteristic layered appearance. Shingles are generally sawn on both faces; cedar shakes, by contrast, are usually split and have a thicker, more irregular surface. Product terminology can vary, so it is useful to confirm whether a quote specifies shingles or shakes.
Western red cedar is a common siding choice because it is relatively light, easy to work, and naturally resistant to decay compared with many untreated woods. Eastern white cedar is another option, particularly in some regional markets. Cedar is not waterproof or immune to insects, rot, or fire. Its service life depends on sound detailing, installation, exposure, and maintenance.
Why Homeowners Choose Cedar Shingles
- Distinctive appearance: Shingles create a fine-grained, dimensional facade that suits traditional, coastal, cottage, and contemporary designs.
- Flexible finishing: Cedar can be left to weather, stained, or painted, subject to the product manufacturer’s recommendations.
- Repairability: Individual damaged shingles can often be replaced without removing an entire wall covering.
- Relatively low weight: Compared with some masonry claddings, cedar puts less weight on the building structure, though the wall assembly still needs to be properly designed.
- Renewable material: Wood is renewable when sourced from responsibly managed forests. Buyers can ask for documentation such as Forest Stewardship Council certification or other credible chain-of-custody information.
These benefits come with tradeoffs. Cedar generally requires more inspection and finish maintenance than many low-maintenance claddings. It can also cost more than basic vinyl siding, and its performance depends heavily on keeping water out of the wall assembly.
Common Cedar Species, Grades, and Cuts
Species and appearance
Western red cedar often has a warm range of brown, reddish, and pale tones, while eastern white cedar may begin lighter and weather differently. Natural variation is expected: boards can differ in color and grain, even within one package. Exposure to sun, rain, and shade affects how quickly the surface changes.
Grades and defects
Manufacturers classify shingles by appearance and intended use. Higher appearance grades typically have fewer visible defects and a more uniform look; lower or utility grades may have more knots or other variation. Grade names and standards are not always identical across suppliers, so the specification should identify the applicable grading rules and the face intended to be exposed.
Shingle thickness, width, length, and exposure also matter. A larger exposure shows more of each shingle and can reduce the number of pieces needed, but the permitted exposure depends on the product, wall conditions, and local requirements. Follow the manufacturer’s installation instructions rather than selecting exposure based on appearance alone.
Natural Cedar Shingle Siding Costs
Installed prices vary widely across the United States. As a broad planning range, cedar shingle siding may cost roughly $8 to $18 or more per square foot installed, with premium materials, complex architecture, difficult access, regional labor rates, and wall repairs pushing projects higher. This is an estimate, not a guaranteed market price; local bids are essential. “Square foot” usually refers to the siding area, but contractors may calculate openings, waste, and trim differently.
Material-only prices can also vary substantially by species, grade, profile, finish, and supplier. The siding itself is only one part of the budget. A complete estimate may include tear-off and disposal, sheathing repair, water-resistive barrier, flashing, furring for a rainscreen, starter strips, corner details, trim, fasteners, finish, scaffolding, and permit fees.
For comparable bids, ask contractors to state the product and grade, measured wall area, expected waste, installation exposure, underlayment and drainage details, finish system, and warranty terms. Confirm whether rot repair, window flashing, and disposal are included. A low bid that omits essential moisture-control work may not represent a lower-cost project over time.
How Cedar Shingle Siding Is Installed
A durable installation begins with a sound, dry wall substrate and a drainage strategy. Cedar shingles are a cladding layer, not the building’s primary water barrier. Behind them, the wall typically has a water-resistive barrier (WRB), properly integrated flashing, and—where specified—a drainage or ventilation space. Local codes, climate, wall design, and manufacturer instructions determine the appropriate assembly.
- Inspect and prepare the wall: Correct damaged sheathing and address existing moisture problems before covering the structure. Install a compatible WRB and tape or lap seams as specified.
- Flash openings and transitions: Integrate head flashing, sill details, doors, windows, roof-wall intersections, and penetrations with the WRB so water is directed outward.
- Provide drainage where required: A rainscreen gap can help water drain and promote drying behind the siding. Furring strips or a drainage mat may be used in suitable assemblies; details should match the design and code requirements.
- Establish the layout: Install starter courses and corners carefully. Stagger joints between courses so adjacent joints do not line up, and maintain the specified side and end clearances.
- Fasten correctly: Use corrosion-resistant fasteners suitable for cedar and the exposure conditions. Fastener type, length, placement, and penetration into framing or sheathing should follow the product instructions and applicable code.
- Finish and protect: Apply any specified primer, stain, or paint to the correct surfaces and at the recommended time. Keep siding clear of soil and other surfaces that can hold moisture.
Installation details around windows, decks, roofs, and corners deserve particular attention. Poorly integrated flashing can allow water behind the siding, where damage may remain hidden. In regions with heavy rain, wind-driven precipitation, snow, or high humidity, a qualified contractor familiar with local building practices can help design the wall assembly.
Should Cedar Be Left Natural, Stained, or Painted?
“Natural” can describe cedar’s material rather than a finish choice. If left unfinished, exposed cedar generally changes color as ultraviolet light and moisture weather the surface. In many locations it gradually becomes gray, but the result may be uneven: shaded walls, eaves, and areas protected from rain can age differently from sunny, exposed elevations. Dirt, algae, and pollution can also affect appearance.
A transparent or semitransparent stain can add color while allowing some grain to show. A solid-color stain or paint provides more uniform color and can offer additional surface protection when applied as a compatible system. No finish eliminates maintenance. Finish performance depends on exposure, surface preparation, product quality, application, and local climate.
Follow the siding and coating manufacturers’ instructions, including requirements for priming, back-priming, end-grain treatment, and application timing. If a uniform look matters, test the finish on sample shingles and view them on different sides of the home. Cedar can absorb finishes differently from one piece to another.
Maintenance and Inspection
Inspect cedar siding at least once a year and after severe storms. Look for loose, cracked, split, or missing shingles; failed caulk where caulk is specified; damaged flashing; clogged drainage paths; and signs of staining or moisture. Check areas near gutters, downspouts, decks, roof edges, and ground level, where water exposure is often greatest.
- Keep gutters and downspouts clear and direct water away from the walls.
- Trim plants so the siding can dry and is not continuously rubbed or shaded by dense growth.
- Maintain clearance between siding and soil, paving, roofing, and other surfaces according to product instructions and local code.
- Replace damaged shingles promptly, matching the original size, species, grade, and exposure as closely as practical.
- Clean gently with methods approved by the siding and finish manufacturers; aggressive pressure washing can damage wood and force water behind the cladding.
- Renew stains or paint when the finish shows wear, following the coating manufacturer’s preparation and recoat guidance.
Maintenance intervals cannot be predicted by a single rule. A sunny, wind-driven-rain exposure may need attention sooner than a sheltered wall. A homeowner should assess each elevation separately and keep records of finishes and repairs.
Fire, Moisture, and Building-Code Considerations
Wood siding is combustible. Cedar’s natural decay resistance does not make it fire-resistant, and fire performance depends on the complete wall assembly and any tested treatment. In wildfire-prone areas, local rules may limit wood products or require ignition-resistant materials, noncombustible detailing, or specific fire-retardant-treated products. Requirements can vary by state, county, and municipality, so confirm them with the local building department and insurer before purchase.
Fire-retardant treatment is not the same as making wood noncombustible. Treated siding must be suitable for exterior exposure, installed as directed, and maintained according to its documentation. Buyers should obtain product labels and test or evaluation information rather than assuming that any coating meets local requirements.
Moisture control is equally important. Cedar can absorb water and decay if it stays wet, while trapped moisture can damage sheathing and framing behind it. Proper flashing, drainage, ventilation where designed, and clearance from persistent moisture sources help protect the wall. The International Residential Code provides model requirements, but adopted code editions and local amendments differ. Permits and inspections may be required.
How Cedar Compares With Other Siding
| Material | Appearance | Maintenance and considerations |
|---|---|---|
| Natural cedar shingles | Real wood grain and layered texture | Needs inspection and periodic repair or finish care; combustible |
| Fiber-cement shingles | Can imitate wood profiles with consistent dimensions | Finish maintenance still applies; heavier, and cutting requires dust precautions |
| Vinyl siding | Available in many colors and profiles, but lacks natural wood grain | Often lower upfront cost; can crack or deform and has different repair and recycling considerations |
| Engineered wood siding | Wood-based appearance with manufactured profiles | Product-specific installation and clearance rules; inspect finish and edges |
No material is best for every house. Cedar is a strong choice when authentic wood texture and repairability matter, and the owner is prepared for upkeep. A competing product may suit a project better when fire restrictions, minimal maintenance, budget, or a uniform factory finish takes priority.
How to Choose a Contractor and Product
Request written proposals from contractors experienced with wood shingle siding. Ask for recent projects, references, proof of insurance, and a clear description of the wall assembly. Confirm who is responsible for permits, substrate repairs, flashing, waste removal, and finish application. The contract should specify products, grade, exposure, fastening method, and how concealed damage will be priced if discovered.
For materials, compare more than the sample’s color. Verify species, grade, dimensions, moisture condition, intended exposure, finish compatibility, and applicable certifications. Ask the supplier how the product should be stored before installation and whether it is approved for the intended climate and application. For homes in regulated fire zones, obtain written confirmation that the proposed product and assembly meet local requirements.
Frequently Asked Questions
How long does natural cedar shingle siding last?
There is no guaranteed lifespan. Service life depends on installation quality, climate, exposure, maintenance, and moisture management. A well-detailed wall with prompt repairs can last for decades, while persistent leaks or poor clearances can cause early failure.
Will cedar shingles turn gray?
Unfinished cedar commonly weathers toward gray, but the pace and uniformity vary. Sun, rainfall, shade, and pollution create differences between walls. Stains and paints alter the color and may delay the visible effects of weathering, but they require upkeep.
Can cedar shingles be installed over existing siding?
Sometimes, but only if the existing wall condition, flatness, fastening support, moisture layers, and code requirements allow it. Covering damaged siding or concealing an unresolved leak is not a sound repair. A contractor should inspect the wall and determine whether removal is needed.
Are cedar shingles environmentally friendly?
They are a renewable wood product, but environmental impact depends on forest management, transportation, processing, service life, and disposal. Buyers can seek credible sourcing documentation and choose a durable installation that avoids premature replacement.
