Choosing the right decking material has never been more important and this Decking Material Guide can help with the decision.
Especially now, as the Lower Mainland heads into its relentless rainy season, moisture becomes your deck’s biggest enemy. Creeping into cracks, accelerating rot, and compromising structural integrity far faster than most homeowners realize. Your deck is a major investment, one that impacts curb appeal, resale value, and long-term maintenance costs. Selecting the right material today can mean the difference between a deck that thrives in our wet coastal climate and one that deteriorates season after season.
With so many options available — wood, composite, vinyl, innovative polyurethane systems, etc. — the choices can feel overwhelming. But when rain and moisture are a constant concern, a few factors rise to the top:
- Waterproofing & moisture protection (critical for the BC coast)
- Long-term durability
- Maintenance requirements
- Appearance and customization
- Upfront vs. lifetime cost
- Warranty and peace of mind
In this post, we break down four of the most popular decking types side-by-side, including a comparison chart. and highlight two standout choices designed to perform exceptionally well in wet climates: premium composite decking and the revolutionary OmegaDeck polyurethane waterproofing system from NewPort Dry Deck.
Traditional Wood Decking
Pressure-treated pine, cedar, redwood, and tropical hardwoods like Ipe have been the traditional choice for decades. Wood offers that classic, warm, natural beauty that many homeowners love.
Pros:
- Lowest initial cost
- Authentic wood grain and feel
- Can be stained any colour
Cons:
- High maintenance — annual cleaning, sealing, staining
- Prone to warping, cracking, splintering, rot, and insect damage
- Absorbs water easily → mould, mildew, and structural failure over time
- Typical lifespan 10–15 years even with diligent care
Wood is best for budget-focused homeowners who enjoy DIY upkeep and don’t mind replacing boards periodically.
Composite Decking
Composite decking (wood-plastic composite) exploded in popularity over the last 15 years and remains one of the top choices in 2025. Made from recycled wood fibres and plastic, modern capped composites have a protective polymer shell that dramatically improves performance.
Pros:
- Very low maintenance — just occasional soap-and-water cleaning
- Excellent resistance to rot, insects, warping, and splintering
- Wide range of colours and realistic wood-grain textures
- 25–30+ year lifespan with proper installation
- Many brands now offer 25–50 year fade/stain warranties
Cons:
- Higher upfront cost than wood
- Can get very hot in direct sun (newer “cool-touch” technology helps)
- Not 100% waterproof — water can still penetrate between boards and damage substructure unless properly flashed and sealed
Composite is ideal for homeowners who want the look of wood with minimal upkeep. Newport Dry Deck installs premium composite lines that deliver outstanding durability and beauty.
Vinyl Decking
Sheet vinyl or membrane decking has been the standard waterproof deck solution in Western Canada for 40+ years.
Pros:
- Provides a continuous waterproof membrane
- Moderate cost
- Good colour selection
Cons:
- Glued seams can fail over time
- UV damage causes chalking and fading
- Can peel, bubble, or tear at edges and walls
- Often requires removing siding and doors for proper installation
- Typically 10–15 year lifespan before major failures
Many homeowners end up replacing vinyl multiple times over the life of their home.
OmegaDeck (Polyurethane Membrane)
This is the newest and most advanced category — a trowel-applied, seamless polyurethane system that chemically bonds to the plywood substrate. NewPort Dry Deck’s OmegaDeck (also called OmegaStone) is the premier example.
Pros:
- 100% seamless — no seams, no glues, no leaks ever
- Becomes part of the plywood — literally impossible to peel or tear off
- Extremely tough polyurethane (same material used in mining truck beds that carry 350-ton loads over sharp rocks)
- 20-year full waterproofing warranty
- Beautiful custom flake finishes that hide imperfections and provide slip resistance
- Can be applied over existing vinyl without removing siding or doors
- Minimal maintenance — sweep and hose, no power washing needed
- UV-stable, eco-friendly, LEED-compliant
Cons:
- Requires professional installation (not DIY)
- Slightly higher upfront cost than vinyl, but usually similar or lower lifetime cost
OmegaDeck is rapidly becoming the gold standard for waterproof decks in British Columbia and beyond.
Side-by-Side Decking Materials Guide Comparison Chart
Here is Newport Dry Deck’s Decking Materials Guide – a comprehensive comparison of four of the most popular categories:
Spotlight: The Two Best Options
If you want the absolute best performance, we recommend either:
- Premium Composite Decking from Newport Dry Deck Perfect when you love the rich wood-look but hate maintenance. We install top-tier capped composite lines that stay beautiful for decades with almost zero work.
- OmegaDeck Polyurethane Waterproofing System The ultimate solution for anyone who wants a 100% dry space below their deck forever. Seamless, indestructible, beautiful, and backed by an industry-leading 20-year warranty. No other system matches its longevity and leak-proof performance.
Many clients choose to combine both — composite or wood on top with OmegaDeck waterproofing underneath for the driest, longest-lasting deck possible.
Final Recommendation
Stop settling for decking that fails in 10–15 years. The smartest investment is a system built to last a lifetime with minimal upkeep.
