Cedar Shingles vs Composite Siding — Which Is Right for Your Project?
Composite and synthetic siding have their place. But for DIY projects, accent walls, outdoor structures, and anywhere natural material wins on character and cost — Western Red Cedar is hard to beat. Here's the honest comparison.
| Factor | Western Red Cedar | Composite / synthetic |
|---|---|---|
| Material origin | Natural softwood (Thuja plicata) | Engineered wood fibers + resins, vinyl, or fiber-cement |
| Appearance | Real grain, natural color variation, ages to silver-gray | Uniform, printed wood-look or solid color |
| Natural rot/insect resistance | Yes — cedar's own oils | Depends on product; treatments vary |
| DIY-friendly installation | Yes — cuts and nails easily with basic tools | Varies; some products need special blades or fasteners |
| Environmental impact | Renewable, biodegradable, low carbon footprint | Plastics, adhesives, often non-recyclable |
| Longevity (well-maintained) | 40+ years exterior, decades interior | 20–40 years depending on product |
| Maintenance | Optional staining/sealing every few years; natural weathering looks great | Low maintenance (cleaning only) |
| Upfront cost | Low for #3/#4 undercourse grade — DIY-friendly pricing | Often higher per square foot installed |
| Flavor-enhancing wood (natural cedar) | Yes (natural, untreated) | No — synthetic materials don't impart natural flavor |
| Off-gassing / VOCs | None — cedar is natural and untreated | Varies; resin- and adhesive-based products may off-gas |
When composite makes sense
If your goal is the lowest possible maintenance and you don't mind a synthetic look, composite is a reasonable choice for whole-house siding. Cedar requires a bit more involvement — and rewards it with character and longevity.
When cedar is the better call
Siding for contractors and homeowners who want a distinctive look, DIY projects, accent walls, sheds, gazebos, pergolas, dog houses, man caves, and anywhere natural beauty matters. Cedar delivers warmth, character, and value composite simply can't match.
