Shakes vs. Shingles: The Difference Matters
The terms "wood shake" and "wood shingle" are often used interchangeably, but they describe two distinct products. Wood shingles are sawn on both sides, producing a smooth, uniform surface with consistent thickness from butt to tip. Wood shakes are hand-split on at least one face, creating a rougher, thicker, more textured product with a distinctly rustic appearance.
For replacement projects, shakes are far more common than shingles — their thicker profile and rough texture are what most homeowners are trying to recreate. Wood shingles are more often found on historic homes where a smoother look was original to the structure.
Wood Species Options
Western red cedar is the industry standard — it has a natural resistance to moisture and insects, a straight grain that splits cleanly, and decades of proven performance in North American climates. Three other species are available depending on region and budget:
- White cedar: Slower-growing and denser than western red; slightly more expensive; common in the Northeast
- Alaskan yellow cedar: Extremely durable and rot-resistant; premium pricing; harder to source outside the Pacific Northwest
- Treated pine: Significantly cheaper than cedar; requires pressure treatment to resist rot and insects; shorter lifespan and less aesthetic appeal
What Does a Wood Shake Roof Cost in 2026?
Cedar shakes installed cost $8–$14 per square foot. Wood shingles run slightly less at $6–$11 per square foot installed, reflecting their lower material cost and simpler installation. Both ranges assume professional installation with proper underlayment (typically 30-lb felt or a synthetic equivalent), ridge cap, and flashing.
Note on Class A fire treatment: In jurisdictions requiring Class A-rated wood products, add $1–$2 per square foot to the prices below. Treatment must be applied by a certified applicator and is separate from standard wood preservative treatments.
| Roof Size | Cedar Shakes Installed | Wood Shingles Installed |
|---|---|---|
| 1,500 sq ft | $12,000–$21,000 | $9,000–$16,500 |
| 2,000 sq ft | $16,000–$28,000 | $12,000–$22,000 |
| 2,500 sq ft | $20,000–$35,000 | $15,000–$27,500 |
The Fire Rating Problem
Untreated cedar shakes carry a Class C fire rating — the lowest level of protection — or may be unrated entirely depending on the installation method. Class A is the highest rating, required in most wildfire-prone jurisdictions and many urban areas. Class C shakes burn readily and can allow a fire to spread rapidly across a roofline.
Class A fire-treated cedar shakes are available and are accepted in most jurisdictions that require Class A roofing. The treatment process involves pressure-impregnating the wood with fire retardants. The cost premium is real — $1–$2 per square foot more — but so is the performance difference. Critically, fire treatment does not last the life of the roof; retardants leach out over time. Many manufacturers recommend re-treatment every 10–15 years and require documentation for warranty purposes.
California's Wildland-Urban Interface (WUI) designation covers hundreds of thousands of properties. If your home is in a WUI zone, verify fire rating requirements with your local building department before ordering any wood roofing product. Some California counties have stricter local ordinances than state minimums.
Maintenance Requirements
Wood shakes are not a low-maintenance product. Unlike asphalt shingles that can largely be ignored between replacements, cedar shakes require an active maintenance schedule to reach their full service life:
- Annual inspection: Check for cracked, split, or missing shakes; inspect flashing and ridge cap; look for soft spots in the deck
- Biennial cleaning: Remove debris accumulation, especially in valleys and at eaves where organic matter accelerates decay
- Preservative treatment: Apply wood preservative every 3–5 years to slow moisture absorption and UV degradation
- Moss and algae treatment: As needed, particularly in shaded areas and in humid climates
Properly maintained cedar shakes last 25–35 years. Neglected shakes begin aggressive degradation within 10–15 years — a shortfall that eliminates any cost advantage over asphalt in a hurry.
Moss and Algae: The Pacific Northwest Problem
Moss is a cedar shake's most persistent enemy in high-moisture climates. It holds water against the wood surface, accelerating rot. Algae creates a similar problem with the added issue of making the roof surface slippery and visually dark and stained.
One passive control measure: zinc or copper strips installed at the ridge. Rainwater carries trace amounts of zinc or copper down the roof surface, creating an environment hostile to moss and algae growth. Zinc strips cost $1–$3 per linear foot installed and can meaningfully extend the interval between cleanings. They are not a substitute for cleaning, but they reduce the frequency.
30-Year Cost of Ownership: Cedar vs. Asphalt
The financial case for cedar shakes is difficult to make on a pure cost-of-ownership basis. A quality architectural asphalt shingle roof costs $6–$10 per square foot installed and lasts 25–30 years with minimal maintenance. Cedar shakes cost 40–100% more upfront and require several thousand dollars in cumulative maintenance costs over their lifespan.
The scenario where cedar shakes make financial sense: a high-value property where curb appeal materially affects resale value, in a temperate climate (Pacific Northwest or New England), with an owner who will reliably maintain the roof. The aesthetic premium is real. The financial premium is also real — buyers should go in with clear eyes about what they're paying for.
Insurance and Wildfire Risk
In wildfire-prone states — California, Oregon, Washington, Colorado, Arizona, and others — some insurers have stopped offering coverage for homes with untreated wood shake roofs. Even where coverage is available, premiums may be significantly higher. Before purchasing a home with existing wood shakes, verify insurability and get premium quotes. A roof replacement to a Class A material may be required to obtain coverage at all in certain zip codes.
Where Wood Shakes Still Make Sense
Despite the challenges, cedar shakes remain the right call in specific situations: historic homes where original materials are part of the property's character or are required by a historic preservation commission; high-end properties in temperate, lower-fire-risk climates where the aesthetic commands a price premium at resale; and owners who genuinely enjoy the maintenance relationship with their home and treat the annual inspection as stewardship rather than obligation.
