Fiber Cement vs Cedar Siding
Independent research · Last reviewed August 2026 · Costs are 2026 planning estimates
The short answer
Choose fiber cement for a wood look that resists fire and rot and needs repainting only every ~12 years. Choose cedar for unmatched natural authenticity, if you'll refinish it every 3–5 years. It's durability-and-low-upkeep vs the real thing.
How Fiber Cement and Wood / Cedar really differ
Both give you a wood look, but they ask very different things of you. Cedar is the genuine article — warmth nothing engineered fully matches — at the price of a refinishing cycle every few years. Fiber cement mimics wood convincingly and is non-combustible, rot-proof, and far lower maintenance. If you love wood but not the ladder, fiber cement usually wins; if authenticity is everything, cedar does.
Side by side
| Fiber Cement | Wood / Cedar | |
|---|---|---|
| Installed / sq ft | $6–$14 | $5–$15 |
| Lifespan | 30–50 yrs | 20–40 yrs |
| Repainting | ~12 yrs | ~4 yrs |
| Maintenance | Medium | High |
| Fire | Non-combustible | Melts / burns |
| Wood look | Good | Excellent |
| DIY | Hard | Moderate |
The decision, factor by factor
Cost
Fiber cement runs about $6–$14/sq ft installed; cedar $5–$15. They overlap upfront — but cedar's refinishing every 3–5 years ($1–$3/sq ft each cycle) pushes its lifetime cost well above fiber cement, which repaints only every ~12 years.
Authenticity & looks
Cedar is the genuine article — natural depth, grain, and the way it silvers with age that fiber cement imitates but doesn't fully match. Up close, purists prefer cedar; from the street, quality fiber cement is very convincing and holds its finish far longer.
Maintenance
The widest gap. Cedar needs refinishing every 3–5 years and fails fast if you skip it; fiber cement needs repainting every ~12 years, or 15+ with factory ColorPlus. If you won't keep a ladder handy, fiber cement is the realistic choice.
Durability & fire
Fiber cement lasts 30–50 years, is non-combustible, and resists rot, termites, and impact. Cedar is naturally rot- and insect-resistant but combustible — a poor fit for wildfire zones — and vulnerable if its finish lapses.
Repairability
Cedar wins on repairs: individual boards can be replaced and refinished to blend in. Fiber cement repairs are heavier work and color-matching factory finishes can be tricky, though damage is rarer.
Which should you choose?
Choose Fiber Cement if…
- You want a wood look without the maintenance
- Fire resistance matters (Class A, non-combustible)
- You want the longest lifespan (30–50 years)
- You'd rather repaint every ~12 years than every 3–5
Choose Wood / Cedar if…
- Genuine wood authenticity is non-negotiable
- It's a historic or craftsman home where cedar fits
- You'll commit to refinishing every 3–5 years
- You're not in a wildfire-prone area
The cost difference
Fiber cement runs about $6–$14/sq ft installed; cedar about $5–$15. They overlap upfront — but cedar's refinishing cycle makes its lifetime cost higher. Price both for your home.
