Should I Cover My Deck or Dock in Winter? Myths vs. Facts for Indiana Weather

December is here, and with it comes the unpredictable winter weather that Central Indiana and Pittsburgh residents know all too well. Whether your home sits near Geist Reservoir or you manage a dock along White River, keeping your outdoor wood structures safe through the winter is a serious concern. 

One of the most common questions Premier Deck Coating receives each year is: “Should I cover my deck or dock in winter?” Let’s separate myths from facts and discover the smartest strategies for safeguarding your investment against Indiana’s frosty seasons.

Why Winter Protection Matters in Indiana

Indiana winters can be tough—freeze-thaw cycles, icy rain, snow buildup, and the region’s relentless moisture can take a toll on decks and docks. Untreated wood can warp, crack, or develop mold, leaving behind major damage by spring. Protecting your wooden surfaces isn’t just recommended, it’s essential for minimizing repairs, prolonging lifespan, and preserving your property value.

Myth #1: A Tarp or Cover Is Enough to Protect Your Deck or Dock

Fact: While covering your deck or dock with a tarp sounds like a quick fix, it often does more harm than good, especially in Indiana’s fluctuating winter climate. Moisture trapped under a cover leads to mold growth and wood rot. Wind can whip tarps loose, causing scratches and physical damage. 

If you do opt for a cover:

• Choose breathable materials that allow air circulation.
• Ensure the cover is tightly secured — but not in direct contact with the wood.
• Regularly remove snow and standing water to prevent weight stress on the surface.

However, a professional-grade protective coating—like the elastomeric coatings provided by Premier Deck Coating—is a much more effective and long-lasting solution.

Myth #2: Only New Decks or Docks Need Protection

Fact: Both old and new wood structures benefit from winter protection. In fact, older decks and docks are more susceptible to moisture intrusion and surface degradation. Elastomeric coatings with ceramic microspheres deliver enhanced adhesion, sealing out winter moisture, whether your structure is newly built or in need of restoration.

Myth #3: It’s Too Late to Coat My Deck in December

Fact: Many homeowners think they’ve missed the window for protection once winter arrives. The truth is, professional-grade coatings from Premier Deck Coating can be applied even in early winter, as long as weather conditions are right (dry surface and mild temperatures). Applying a coating now adds a critical layer of defense against Indiana’s harshest months and sets you up for a maintenance-free spring.

Does Snow Damage Unprotected Wooden Decks and Docks?

Absolutely! Snow and ice accumulation can cause several problems for unprotected wood:

• Accelerated cracking from freeze-thaw cycles.
• Wood swelling, cupping, or warping as moisture seeps in.
• Mold and mildew take hold when melting snow remains trapped on the surface.

A professionally applied elastomeric coating forms a waterproof barrier, so snowmelt runs off rather than absorbing into the wood. This is especially crucial for properties bordering lakes or rivers in the Indianapolis and Pittsburgh regions, where moisture is persistent well into spring.

Winter Deck and Dock Care Tips for Indiana Homeowners

Local winter weather brings unique challenges, so here’s how to ensure your deck or dock looks beautiful when spring arrives:

• Sweep off leaves and debris before the first winter storm to reduce mold risk.
• Shovel snow gently with a plastic shovel, going with the grain of the wood.
• Avoid using salt or harsh chemicals, which can degrade wood and coatings.
