Composite vs. cedar decking in Colorado: what actually lasts

This is the question we get on almost every deck estimate: cedar or composite? Both can be beautiful. But our Colorado weather is hard on a deck — thin air, fierce UV, big hailstorms, heavy spring snow, and freeze-thaw all winter. Here's how each one actually holds up out here, what they cost to own, and when cedar is still the right call.

The Colorado sun is the real test

At our altitude there's less air to block UV, so the sun hits a deck harder here than almost anywhere else. That's the single biggest factor.

Cedar fades fast. Left unsealed, that warm reddish-brown can turn silvery-gray in a single summer — sometimes one season. The dry air also pulls moisture out of the wood, which causes surface checks and splits, especially on south- and west-facing decks that bake all afternoon.

Capped composite is built for this. Brands like TimberTech and Deckorators wrap each board in a protective shell with UV inhibitors baked in. That's why they carry fade-and-stain warranties of 25 years on the entry lines, 30 on the mid-tier, and up to 50 years on the PVC boards. The color you pick is roughly the color you keep.

Hail, snow, and freeze-thaw

Colorado is in Hail Alley, and our decks see it. Cedar can dent, bruise, and splinter when big hail comes through. Premium composite shrugs most of it off — many boards are rated to take 1.75-inch hail without damage.

Winter is the other test. Wet spring snow can dump heavy on a deck that was dry the day before, and our temperatures swing across freezing again and again. Wood expands and contracts with that, which over time loosens boards and opens gaps. Quality composite is engineered with the right gapping and hidden fasteners to move with the temperature without buckling or cupping. One nice bonus at our elevation: advanced PVC boards from TimberTech stay up to 30° cooler underfoot than older composites, so they're comfortable in the July sun.

Maintenance: the part people forget

This is where the two materials really split apart.

• Cedar needs a UV-blocking stain or oil every 1 to 2 years in our climate to hold its color and keep from drying out. Each round runs roughly $450 to $850 if you hire it out, plus a weekend if you do it yourself. Skip it and the deck grays and checks early.
• Capped composite needs almost nothing — sweep it, and wash it once or twice a year with soap and water. No sanding, no staining, no sealing. Annual upkeep is more like $5 to $15 in soap.

What it costs over time

Cedar wins on day one. A cedar deck on the Front Range runs about $35 to $55 per square foot installed, while capped composite runs about $50 to $80. So composite costs more to build.

But add up the years. A cedar deck staining bill of a few hundred dollars every other year, plus board replacement down the road, often pushes the 10-year cost of a wood deck past a composite one — by thousands of dollars in many cases. And the lifespans aren't equal: cedar in Colorado tends to last 15 to 20 years (lower end if it's not kept sealed), while capped composite commonly lasts 25 to 30, and premium PVC even longer. If you plan to stay in the home a while, composite usually comes out ahead.

So when does cedar still make sense?

Plenty of times. Cedar is the right pick when:

• You want real wood — the look, the grain, the smell — and you're okay maintaining it.
• Your budget is tighter up front and you'd rather spend less now.
• The deck is shaded or smaller, so the sun does less damage and upkeep is easier.
• You don't plan to stay in the home for the long haul, so the longer lifespan of composite matters less.

And composite is the better call when you want set-it-and-forget-it, the best hail and fade resistance, and the longest life from a deck that bakes in full sun.

Bottom line: in Colorado's sun, hail, and freeze-thaw, capped composite from TimberTech or Deckorators is the easiest deck to own long-term — but a well-kept cedar deck is still a great, lower-cost choice if you love real wood.
