What is the best siding material for Vancouver's rainy climate?

Fiber cement siding is the top choice for Vancouver's wet climate, offering superior moisture resistance, durability, and low maintenance while handling our 1200mm+ annual rainfall exceptionally well.

Fiber cement (brands like Hardie Board) leads the pack because it's engineered specifically for wet climates. It won't rot, warp, or attract insects like wood, and it handles Vancouver's freeze-thaw cycles without cracking. The material breathes naturally, preventing moisture buildup behind the siding, and typically comes with 30-50 year warranties. Installation costs run $8-15 per square foot including labor, making it a solid mid-range investment that pays off long-term.

Vinyl siding offers excellent value at $6-12 per square foot and performs well in our rainy conditions. Modern vinyl won't fade as quickly as older versions, requires virtually no maintenance, and handles moisture beautifully. However, it can become brittle in extreme cold and may not suit Vancouver's character neighborhoods where design guidelines favor more premium materials.

Engineered wood siding (like LP SmartSide) provides the natural wood look many Vancouver homeowners want while offering better moisture resistance than traditional cedar. It's treated with zinc borate for pest and moisture protection, costs $7-13 per square foot, and works particularly well on Vancouver Specials and newer construction where you want wood aesthetics without the maintenance headaches.

Vancouver-Specific Considerations

Our coastal climate demands proper rain screen installation behind any siding material - this isn't optional in BC. The rain screen creates an air gap that allows moisture to drain and dry, preventing the building envelope problems that plagued some 1990s Vancouver condos. BCBC 2024 requires rain screen assemblies for most wall systems, and any reputable contractor will install this as standard practice.

Cedar siding remains popular for character homes in Kitsilano and Mount Pleasant, but requires significant maintenance in our wet climate. Budget for re-staining every 3-4 years ($3,000-8,000 for an average home) and expect some boards to need replacement every 10-15 years. If you choose cedar, ensure proper installation with adequate ventilation and drainage.

Professional installation is crucial regardless of material choice. Improper flashing, inadequate drainage, or poor rain screen installation can lead to expensive building envelope problems. Technical Safety BC doesn't regulate siding installation, but WorkSafeBC coverage is mandatory for all contractors, and you'll want someone experienced with Vancouver's specific moisture management requirements.

For heritage-designated properties or character homes, check with the city's heritage department before choosing materials - some neighborhoods have design guidelines that may influence your options.
