What Are the Disadvantages of Cedar Siding? 7 Real Problems
Joe's Note: Cedar is beautiful — I won't argue that. But after 20+ years replacing siding in Minnesota, I've torn off more rotted cedar than I can count. Homeowners deserve the full picture before they commit to it. Here are the real disadvantages I've seen firsthand.
What Are the Disadvantages of Cedar Siding?
Cedar siding has genuine appeal — natural beauty, a warm aesthetic, and decent insulation value. But it comes with significant trade-offs in cost, maintenance, and longevity that many homeowners don't fully understand until they're already committed. In Minnesota's climate especially, cedar demands more attention and investment than most alternatives.
About Modern Exterior Systems
We're a women-owned, family-operated exterior contractor in Eden Prairie, Minnesota, with 20+ years of construction experience. We're BBB A+ rated, NRCA members, and install cedar, LP SmartSide, James Hardie, and vinyl siding. We've replaced enough cedar to know exactly where it fails — and where it still makes sense.
The 7 Biggest Disadvantages of Cedar Siding
1. High Upfront Cost
Cedar siding typically costs $8–$14 per square foot installed in Minnesota, compared to $7–$12 for LP SmartSide and $6–$8 for vinyl. For a typical 2,000 sq ft home, that's a difference of $8,000–$16,000 more than engineered wood alternatives.
2. Intensive Maintenance Requirements
This is cedar's biggest practical drawback. Cedar siding needs staining or painting every 3–5 years , annual inspections for cracks and moisture damage, regular cleaning to prevent mildew, and prompt repair of any damaged boards. Over a 30-year period, maintenance costs can add $15,000–$25,000 beyond the initial installation.
3. Vulnerability to Moisture and Rot
Despite cedar's natural rot resistance (from its oils), it's not rot-proof — especially in Minnesota. Our freeze-thaw cycles drive moisture deep into wood grain, and when cedar's natural oils deplete over time (typically after 10–15 years), the wood becomes increasingly vulnerable.
Most common failure points: Bottom courses near grade, areas behind downspouts, anywhere caulking has failed, and north-facing walls that stay damp longer.
4. Susceptibility to Insects
While cedar's natural oils repel insects initially, that protection fades as the wood ages. In Minnesota, the main concerns are carpenter ants (they'll nest in softened, moisture-damaged areas), woodpeckers (they'll drill into cedar siding looking for insects), and termites (less common in Minnesota but still a risk).
5. Splitting, Cracking, and Warping
Cedar is a softwood that moves significantly with moisture changes. In Minnesota, where we go from bone-dry winter air to humid summers, cedar boards can cup and warp, split along the grain at nail points, and check from UV exposure. Engineered products like LP SmartSide resist these issues because the wood fibers are treated and bonded under pressure.
6. Inconsistent Quality
Not all cedar is created equal. Much of what's sold today is faster-grown plantation cedar with wider grain, lower oil content, and reduced durability. Unless you're specifying premium clear-grade cedar, the product you get may not perform like cedar installed 30 years ago.
7. Environmental and Sustainability Concerns
Harvesting old-growth cedar raises environmental questions. Engineered wood products like LP SmartSide use fast-growth, sustainably harvested wood strands — getting more siding from less timber.
Cedar Siding vs. Alternatives: Cost and Maintenance Comparison
| Factor | Cedar | LP SmartSide | James Hardie | Vinyl |
|---|---|---|---|---|
| Installed cost (per sq ft) | $9–$16 | $7–$12 | $7–$12 | $6–$9 |
| Repaint/restain interval | 3–5 years | 7–15 years | 10–15 years | Never |
| Lifespan | 20–40 years | 30–50+ years | 30–50+ years | 20–40 years |
| 30-year maintenance cost | $15,000–$25,000 | $3,000–$6,000 | $3,000–$5,000 | $500–$2,000 |
Premium Alternatives We Recommend Instead
- LP SmartSide — Our top recommendation. Engineered wood treated with SmartGuard for rot, termite, and fungal resistance. 50-year substrate warranty.
- James Hardie Fiber Cement — The gold standard for fire resistance and dimensional stability. ColorPlus factory-applied finish carries a 15-year warranty.

- Metal Panel and Rain Screen Systems — For contemporary or mixed-material designs. Zero maintenance and 40+ year lifespan.
When Cedar Still Makes Sense
- Historic homes where maintaining original materials matters

- Homeowners who enjoy hands-on maintenance
- Budget allows for premium-grade cedar and professional maintenance
Frequently Asked Questions
How long does cedar siding actually last in Minnesota?
With diligent maintenance, 30–40 years. Without proper maintenance, I've seen it fail in as few as 15 years.
Is cedar siding worth the extra cost over LP SmartSide?
For most Minnesota homeowners, no. LP SmartSide gives you a similar wood-grain aesthetic at lower upfront cost, with dramatically lower maintenance requirements.
Can cedar siding be repaired, or does it need full replacement?
Individual boards can be replaced, but matching the color and weathering of existing cedar is difficult.
Does cedar siding add to home resale value?
It depends. In upscale neighborhoods where natural materials are expected, well-maintained cedar can add value. Poorly maintained cedar is a red flag for buyers.
What's the best alternative to cedar siding in Minnesota?
LP SmartSide is our top recommendation. James Hardie fiber cement is another excellent option if you prefer a smoother finish.
