Installing a new deck or replacing an old one is a significant investment in your home. To protect that investment, more homeowners and contractors are now seeking durable, weatherproof decking materials that resist rot, warping, cracking, and fading over time—all while requiring minimal maintenance. But which materials are considered weatherproof vs. weather resistant, and how do these materials compare to one another? The Northern Building Supply experts are ready to help you make an informed decision.
The Most Effective Weatherproof Decking Materials
When it comes to truly weatherproof decking, composite and PVC lead the way. Let’s walk through why these materials are excellent choices for withstanding the elements.
Composite Decking
Composite decking is crafted from a blend of wood fibers, plastics, and binding agents. These materials combine to create decking that’s denser, stronger, and more durable than traditional wood. Composite decking often comes with protective coatings to make it resistant to stains, scratches, and fading.
Some of its main benefits include:
- Resistant to moisture, rot, and insects
- Minimal maintenance—no sanding, sealing, staining, or painting
- Long-lasting with a high-quality appearance
Trex is an industry leader in composite decking, known for offering the highest quality materials and construction. Its decking products feature deep wood-grain details for a sleek and authentic appearance. Plus, protective shell technology adds another layer of weatherproofing. It is also an eco-friendly option made from 95% recycled materials. Trex provides a range of options for durability, aesthetics, and budget, all featuring impressive fade resistance and vibrant color retention.

PVC Decking
PVC is another popular type of weatherproof decking. Its entirely plastic composition holds up well against weather over time. Unlike composite, PVC decking doesn’t contain any wood, making it completely immune to moisture and rot. This makes it an ideal choice for regions with high humidity, heavy rainfall, or near water—such as lakes, ponds, or even pools.
Thanks to advanced manufacturing techniques, PVC decking often includes UV inhibitors that help maintain its vibrant color, even after years of sun exposure. Additionally, its nonporous surface resists staining and makes it a low-maintenance option. Aside from staining, PVC is also highly resistant to scratches, dents, and other types of wear, ensuring it maintains its pristine appearance over time—even in high-traffic outdoor spaces.
Some of its main benefits include:
- 100% waterproof
- Excellent resistance to fading and staining
- Lightweight and easy to install, especially when compared to wood
TimberTech’s Advanced PVC decking stands out for its exceptional durability and realistic wood styles. The four-sided protective cap, absence of wood or organic fillers, and solid core construction protect against moisture and degradation over time. Plus, they are engineered from 100% polymers to provide a strong, low-maintenance decking solution for your outdoor space. They are designed to effectively resist scratches, fading, and stains for decades. Northern Building Supply carries TimberTech’s Advanced PVC collections, including:
- Vintage™: Sophisticated highlights, lowlights, and loss-gloss treatments make these PVC deck boards closely resemble high-end hardwoods, such as ipe and teak. While capturing the beauty of natural wood, it also boasts a Class A flame spread rating—making it a better choice for fire-prone areas.

- Harvest™: A painted-wood look without the upkeep. Engineered to resemble wood grain patterns, these decking boards come in a few refreshing shades ideal for creating an inviting-but-modern outdoor gathering area.
Whether you choose composite or PVC, you’re investing in a decking material built to last—even in the most extreme weather events or climates.
Additional Weather-Resistant Options for Decking Projects
If you’re not ready to invest in a fully weatherproof decking material, several other options offer strong resistance to weather-related damage while maintaining a natural wood aesthetic.
Pressure-Treated Wood Decking
Pressure-treated wood is a cost-effective, widely available option that’s often milled from Southern Yellow Pine and chemically treated to repel rot, fungus, and insects. While it’s not maintenance-free, it’s a durable choice for those seeking a traditional wood deck. It remains the top decking material sold in the United States.
Cedar Decking
Cedar is prized for its natural beauty, rich color, and weather resistance. Its oils and tannins naturally repel decay and insects, making it a strong contender for decks exposed to the elements. The deck boards also maintain their shape well over time, resisting warping, cupping, and twisting. When left untreated, it naturally ages to a gentle silvery-gray hue.
Hardwood Decking
Hardwood decking, often crafted from exotic woods, boasts exceptional strength and longevity. Certain species, such as Ipe, are particularly durable and resistant to insects and weather. However, hardwood can be costly and may require consistent upkeep to maintain its appearance. Just like cedar decking, hardwoods can develop a soft silvery finish if not stained.
Signs of Weather Damage on Your Deck
If you’re deciding whether to replace your current deck with a weatherproof option, consider these telltale signs of weather damage:
- Warping or Cracking: Wooden decking, in particular, is prone to warping or cracking after prolonged exposure to moisture or sunlight. These changes in shape can compromise the deck’s structural integrity, creating uneven surfaces or potential tripping hazards. Warping often occurs due to repeated cycles of wetting and drying, while cracking may result from the wood shrinking as it dries out.
- Rot or Mold: Signs of rot, such as dark spots, soft areas, or fungal growth, indicate that moisture has infiltrated the material. Mold and mildew not only weaken the structure but can also pose health risks. Even composite decking with wood fibers may be susceptible to mold if not properly maintained, making it critical to address these issues promptly.
- Fading: Prolonged sun exposure can cause wood and lower-grade composite materials to fade, leaving your deck looking dull and aged. UV rays break down the surface of the material, leading to discoloration that diminishes your deck’s aesthetic appeal. Fading is especially common in regions with intense sunlight, where unprotected materials are exposed year-round.
- Loose Boards or Railings: Over time, weather fluctuations can weaken fasteners and connections, causing boards, railings, or posts to become loose. This not only impacts the deck’s stability but also creates safety concerns. Loose components should never be ignored, as they can signal more extensive underlying damage to the structure.
If you notice these issues, investing in a weatherproof decking material could save you time, money, and headaches in the long run.
Why Weatherproof Decking is Worth the Cost
Although composite and PVC decking may cost more upfront than wood, their long-term benefits make them a smart investment. Here’s why:
- Minimal Maintenance: Forget sanding and sealing—weatherproof decking materials stay low-maintenance for years to come. On average, maintaining a wood deck can cost between $200 and $500 annually for cleaning, sealing, and repairs. Over 10-15 years, these costs can add up to thousands of dollars, making the higher initial cost of composite or PVC a more economical choice in the long run.
- Long Lifespan: Weatherproof decking is built to last, reducing the need for frequent repairs or replacements. While wood decks typically last around 15 years, composite and PVC options can last 25–30 years or even longer in many cases.
- Enhanced Aesthetic: High-quality finishes ensure your deck remains beautiful year after year, regardless of season, without requiring re-staining or repainting. While premium options can cost more upfront, they often feature advanced technologies like capped finishes, which protect against scratches, stains, and fading.
- Sustainability: Many composite and PVC brands, including Trex and TimberTech, use recycled materials to construct their weatherproof decking materials. You’re not only investing in your home’s value—you’re investing in the environment, too.
How to Maintain Your Weatherproof Decking
Even though composite and PVC decks are low-maintenance, there are a few simple steps to keep them looking their best. Here’s what our experts recommend:
- Regular Cleaning: Hose down your deck to remove dirt and debris, and occasionally use a mild soap with a soft brush for a deeper clean.
- Prevent Stains: While these materials are very stain resistant, you can exercise extra caution by using furniture glides and cleaning up spills quickly.
- Inspect for Damage: Periodically check for scratches or signs of wear to ensure your deck remains in top condition.
- Seasonal Care: Remove leaves or snow buildup in the fall and winter to prevent any surface blemishes, especially on lighter-colored boards, though most debris will not leave a mark and can be easily hosed off.
