Best Siding Materials for Pacific Northwest Homes: A Complete Comparison

Your home's siding is its first line of defense against the Pacific Northwest's notorious moisture, temperature swings, and severe weather. Choosing the right siding material isn't just about curb appeal—it's about durability, maintenance requirements, and long-term protection. In Spokane and throughout the region, different materials perform vastly differently. This comprehensive guide compares the most popular options to help you make the best choice for your home and climate.

Understanding Pacific Northwest Siding Challenges

The Pacific Northwest presents unique challenges for exterior siding:

The best siding for this climate resists moisture penetration, expands and contracts predictably, and maintains integrity through weather extremes.

Vinyl Siding

Vinyl Siding

Vinyl is the most popular siding choice in North America, prized for affordability and low maintenance. Modern vinyl resists fading, moisture, and rot. However, it has limitations in extreme climates.

Cost Range

$3.50 - $8.00 per square foot installed — The most budget-friendly option. Standard vinyl is cheaper; premium vinyl costs more but resists fading better.

Pros

  • Lowest upfront cost
  • Minimal maintenance (occasional cleaning)
  • Won't rot or attract termites
  • Wide color selection
  • Quick installation
  • Compare the actual written warranty and exclusions

Cons

  • Brittles in extreme cold
  • Expands/contracts significantly with temperature changes
  • Can warp or buckle if installed improperly
  • Damage requires board replacement
  • Lower-end vinyl fades noticeably
  • Less resale value than premium materials

Performance in Pacific Northwest

Compare the proposed vinyl product’s appearance, temperature limitations, installation requirements and warranty for the actual home. Expansion allowances and fastening details must come from that product’s current written instructions.

Fiber Cement and Engineered Wood Siding

Fiber Cement Siding

Fiber cement and engineered wood are different siding materials. James Hardie offers fiber cement siding; LP SmartSide is engineered wood. Compare the actual product, finish and care requirements instead of treating the two as interchangeable.

Cost Range

$6.50 - $12.00 per square foot installed — Mid-to-premium pricing. James Hardie commands slightly higher prices than LP SmartSide.

Pros

  • Excellent moisture resistance
  • Won't rot, warp, or attract termites
  • Service life depends on the product, installation, exposure and care
  • Authentic wood appearance
  • Confirm the fire classification of the specific product and wall assembly
  • Holds paint well
  • Strong resale value

Cons

  • Higher upfront cost than vinyl
  • Review the selected finish’s care and recoating requirements
  • Joint and flashing details must follow the actual siding instructions
  • Heavier than vinyl (requires skilled installation)
  • Follow the selected product’s written instructions for cut edges and finish care
  • Can splinter if damaged

Performance in Pacific Northwest

For a Spokane home, compare fiber cement, engineered wood and vinyl by appearance, finish care, budget and the requirements of the wall assembly. James Hardie and LP SmartSide belong to different material families and have different product instructions. Confirm the finish and written warranty rather than assuming one repainting interval or lifespan.

James Hardie vs. LP SmartSide

James Hardie fiber cement and LP SmartSide engineered wood are different material families. Compare actual profiles, finish options, handling and care requirements. Use the current instructions for the selected product; do not substitute another brand’s installation details.

Natural Wood Siding

Natural Wood Siding

Cedar, redwood, or pine siding offers classic beauty and excellent insulation, but requires significant maintenance in wet climates.

Cost Range

$8.00 - $15.00 per square foot installed — Premium material with premium maintenance costs.

Pros

  • Beautiful, authentic appearance
  • Excellent insulation value
  • Can be stained or painted
  • Can be repaired by replacing individual boards
  • High-end aesthetic

Cons

  • Requires frequent maintenance (annual inspection)
  • Finish care depends on the actual wood and coating system
  • Prone to rot in wet climates
  • Attracts termites and insects
  • Warps and splits with temperature changes
  • Very expensive to maintain long-term
  • Long-term condition depends on the wood, finish, installation and care

Performance in Pacific Northwest

Natural wood may suit some homeowners’ appearance and care preferences. Compare the actual species, profile, finish and exposure with other siding options. Confirm the wall assembly, installation details and ongoing finish care before deciding.

Metal Siding

Metal Siding

Aluminum or steel siding is less common in residential applications but offers excellent durability in harsh climates.

Cost Range

$7.00 - $12.00 per square foot installed — Similar to premium vinyl or fiber cement.

Pros

  • Review the actual metal, coating and written warranty
  • Doesn't rot, warp, or attract insects
  • Excellent in freeze-thaw climates
  • Low maintenance
  • Lightweight (easier installation)
  • Recyclable material

Cons

  • Can dent from impact
  • Conducts cold/heat (insulation issues)
  • Confirm the complete wall assembly and selected product requirements
  • Industrial appearance (not common residentially)
  • Rust concerns (aluminum corrodes over time)
  • Limited residential availability

Performance in Pacific Northwest

Metal siding performs well in harsh climates but is rarely chosen for residential homes in the PNW due to appearance and thermal issues. It's more common on commercial buildings or harsh-climate applications. Not recommended unless you specifically prefer the industrial aesthetic.
