Composite Decking vs Wood Decking in Central Oregon
Composite decking runs about 35 to 55 dollars per square foot installed in Central Oregon, roughly twice the cost of pressure treated wood, but it holds up far better against the region's intense high elevation UV and wide day to night temperature swings that crack and gray wood decking. Wood costs less upfront and can look great, but plan on restaining it every one to two years here instead of the three to four years typical in milder, wetter parts of the state.
How Central Oregon's Climate Puts Extra Stress on Deck Materials
Bend sits around 3,600 feet in elevation, and that altitude means more intense UV exposure than most homeowners are used to, even on days that don't feel especially hot. That extra UV breaks down the surface fibers of wood decking faster than it would at sea level, leading to graying, splintering, and surface checking sooner than the same board would show in a milder, lower elevation climate.
The region's big swings between summer daytime heat and cool nights, plus very low humidity most of the year, also dry wood out and cause it to expand and contract repeatedly. That repeated movement is what eventually opens cracks along the grain and loosens fasteners over time.
Cost, Lifespan, and Climate Performance Compared
Here's how the two options generally compare for a typical Central Oregon deck project.
| Wood (Cedar or Pine) | Composite | |
|---|---|---|
| Installed cost per sq ft | $18 to $35 | $35 to $55 |
| Typical lifespan | 15 to 20 years with regular upkeep | 25 to 30-plus years |
| Climate performance | Prone to checking, splitting, and graying from intense UV and dry heat, needs restaining every 1 to 2 years | Resists UV fading better when capped, doesn't absorb moisture, but dark colors can get hot underfoot in full sun |
Which One Makes Sense for Your Deck
If you plan to stay in your home long term and want to spend less time on upkeep, composite usually pencils out despite the higher installed cost, since it skips the recurring staining and repair work wood needs in this climate.
If budget is the priority, or you like the look and feel of natural wood and don't mind maintaining it, cedar or pressure treated wood remains a reasonable choice, as long as you're realistic about restaining it more often than you would on the west side of the state.
Frequently asked questions
Does composite decking get too hot to walk on barefoot in Central Oregon summers?
Yes, dark colored composite can reach well over 120 degrees in direct July or August sun, often hotter than wood decking in the same spot. Lighter colors and shaded areas help a lot.
How often does a wood deck need to be restained in this climate?
Because of intense high desert UV and low humidity, most wood decks need restaining every 1 to 2 years to prevent cracking and graying, more often than in wetter, lower elevation climates.
Is composite decking worth the higher upfront cost?
For homeowners planning to stay long term, composite usually pays off because it avoids the recurring staining and repair costs wood needs in this climate. For a shorter hold or tighter budget, wood is still a reasonable choice.
Can Central Oregon's temperature swings crack a wood deck on their own?
Yes, large day to night and season to season temperature swings cause wood to repeatedly expand and contract, which speeds up checking and splitting, especially on boards that aren't sealed on a regular schedule.
