Cedar Shake Roofing in Indiana: Complete Homeowner's Guide
Cedar shake roofing has a look that no other material can replicate. The natural grain patterns, warm tones, and textured surface of hand-split cedar shakes give a home character that factory-made materials simply cannot match. Cedar has been used as a roofing material in North America for centuries, and it remains a popular choice for homeowners who value craftsmanship and natural aesthetics.
But cedar is also a demanding material. It requires more maintenance than asphalt shingles or metal, has specific fire safety considerations, and performs differently in Indiana’s climate than it does in the Pacific Northwest where most cedar originates. Here is what you need to know before choosing a cedar shake roof for your Indiana home.
Cedar Shakes vs. Cedar Shingles
These terms are often used interchangeably, but they describe different products:
Cedar shakes are hand-split or taper-sawn from cedar logs. The split surface creates a rough, textured appearance with natural grain patterns exposed. Shakes are thicker (typically 3/4 inch at the butt end) and provide a rustic, dimensional look. Hand-split shakes have the most character; taper-sawn shakes have one smooth side and one textured side.
Cedar shingles are machine-sawn on both sides, producing a smooth, uniform appearance. They are thinner than shakes and create a more refined, even roofline. Cedar shingles work well on homes where a cleaner aesthetic is preferred.
Both products come from Western Red Cedar, which is naturally resistant to moisture, insects, and UV degradation. The choice between shakes and shingles is primarily aesthetic.
Cedar Grades and What They Mean
Cedar roofing products are graded by the Cedar Shake & Shingle Bureau (CSSB). The grades that matter for roofing:
Certi-Split (shakes) / Blue Label (shingles) — Premium grade. 100% edge grain, 100% heartwood, no defects. This is what you want on a roof. Heartwood contains the natural oils that make cedar resistant to moisture and rot. Edge grain ensures the wood expands and contracts evenly with moisture changes.
Certi-Sawn (shakes) / Red Label (shingles) — Good quality but allows some flat grain and limited sapwood. Acceptable for roofing but will not perform as long as premium grade in Indiana’s moisture-heavy climate.
SPG Roofing & Exteriors uses only premium-grade Certi-Split or Blue Label cedar on roofing installations. The cost difference between grades is modest compared to the lifespan difference.
How Cedar Shake Performs in Indiana
Indiana’s climate creates specific challenges and advantages for cedar roofing.
Moisture management is critical. Indiana averages 42 inches of rainfall annually plus significant humidity in summer. Cedar is naturally moisture-resistant, but it needs airflow to dry properly between rain events. A cedar shake roof must have a ventilated underlayment system — typically a matrix of furring strips over synthetic felt — that allows air to circulate beneath the shakes. Without this ventilation layer, trapped moisture accelerates rot. This is the single most common installation error with cedar roofs.
Freeze-thaw cycles are manageable. Cedar’s cellular structure handles freeze-thaw expansion better than rigid materials like clay tile. The wood fibers flex rather than crack. Premium heartwood cedar resists water absorption, which further limits freeze-thaw damage. In Indiana’s climate, a properly installed cedar roof handles winter well.
Hail is a concern. Cedar is softer than asphalt, metal, or tile. Hail impacts can split or crack individual shakes, especially older ones that have dried and hardened. After a significant hail event, cedar roofs need inspection and replacement of damaged shakes. This is a maintenance reality in Central Indiana.
UV exposure causes weathering. New cedar has a golden-brown color. Over 1 to 3 years of UV exposure, untreated cedar weathers to a silver-gray patina. Some homeowners prefer this natural aging; others want to maintain the original color. UV-protective treatments can slow the weathering process, but they require reapplication every 3 to 5 years.
Fire Safety and Cedar Roofing
Untreated cedar is rated Class C for fire resistance — the lowest class. This is a legitimate concern, and building codes in some jurisdictions restrict untreated wood roofing.
The solution is fire-retardant treated (FRT) cedar. Pressure-treated FRT cedar shakes achieve Class A or Class B fire ratings, meeting the same standard as asphalt shingles and metal. The treatment penetrates the wood fibers and does not wash off in rain.
SPG Roofing & Exteriors recommends and installs fire-retardant treated cedar for all Indiana projects. The cost premium for FRT treatment is typically 15 to 25 percent over untreated material — well worth the safety improvement and code compliance.
Maintenance Requirements
Cedar demands more maintenance than asphalt shingles or metal roofing. Homeowners who choose cedar should expect:
-
Annual inspection: Check for cracked, split, or missing shakes, especially after storm events. Look for moss, lichen, or algae growth on north-facing slopes.
-
Debris removal: Keep the roof surface clear of leaves, pine needles, and branches. Trapped organic debris holds moisture against the wood and promotes decay. This is especially important in fall.
-
Moss and algae treatment: Indiana’s humidity encourages organic growth on cedar. Zinc or copper strips installed at the ridge line help prevent growth. Existing moss should be removed gently — never pressure wash a cedar roof, as it strips away the soft wood fibers and dramatically shortens the roof’s life.
-
Re-treatment every 3 to 5 years: If you want to maintain the original cedar color or apply UV/water protection, the roof needs periodic treatment with a cedar-compatible preservative or stain.
-
Individual shake replacement: Cracked or split shakes should be replaced as they appear. A skilled roofer can replace individual shakes without disturbing the surrounding installation.
For homeowners willing to invest this maintenance effort, a cedar roof can look beautiful and perform well for 30 to 40 years. For those who want a low-maintenance option with a similar long lifespan, metal roofing or premium asphalt shingles are better choices.
Cedar Shake Roofing Costs in Indiana
Installed costs for cedar shake roofing in the Indianapolis area typically fall in these ranges:
- Cedar shakes (premium grade, FRT): $12,000 to $30,000 for an average-sized home
- Cedar shingles (Blue Label): $10,000 to $25,000
- Periodic maintenance (annual): $200 to $600 depending on roof size and access
- Full re-treatment (every 3–5 years): $1,500 to $4,000
By comparison, an asphalt shingle roof costs $8,000 to $20,000 but lasts 20 to 25 years versus 30 to 40 for cedar. A standing seam metal roofing costs $15,000 to $35,000 and lasts 50+ years with virtually no maintenance. The total cost of ownership over 50 years often favors metal, but cedar wins on aesthetics for homeowners who value the natural wood look.
Is Cedar Shake Right for Your Indiana Home?
Cedar shake roofing is the right choice if you value natural aesthetics above all else, are committed to the maintenance schedule, and want a roof material with genuine character. It is not the right choice if you want set-it-and-forget-it durability, are concerned about hail damage in Indiana’s storm season, or prefer the lowest possible total cost of ownership.
