Tips to Protect Your Outdoor Living Space This Winter

As the winter months settle in, we’ve definitely felt the bite. Record low temperatures from the Artcic has prompted us to consider more robust ways to protect our properties from extreme weather. And though it’s commong for homeowners to turn their attention to indoor comfort, it’s also important to remember to maintain the exterior of your home — especially your deck.

Extreme cold temperatures, snow, ice, and even high winds can all contribute to wear and tear on your deck, potentially causing damage that can lead to costly repairs in the spring. However, with a little preparation and care, you can protect your deck and extend its lifespan. In this article, we’ll walk you through essential tips for maintaining your deck during the cold winter months.

Cold Weather Deck Care Tips

1. Inspect Your Deck for Winter Readiness

Before the first heavy snowfall or frost, it’s a good idea to inspect your deck for any existing damage. Freezing temperatures and moisture can cause wood to contract and expand, which might lead to cracks, splinters, or warped boards.

  • Check for Loose Boards or Nails: Make sure all the deck boards are securely fastened, and look for any loose nails or screws that could cause tripping hazards.
  • Examine for Rot or Mold: Winter moisture can exacerbate any existing rot or mold. If you spot any signs of decay, now is the time to address them before they worsen.

If you’re unsure whether your deck is in good shape, consider having a professional inspection done by Noble Roofing. Catching small issues early can save you from larger, more expensive repairs come spring.

2. Remove Snow and Ice Off Your Deck — the Right Way

Having just received around a foot of snow, this tip is very timely. While it may seem like a simple task, clearing snow and ice off your deck requires a bit of care. Using the wrong tools or techniques can damage your deck’s surface, so here are a few tips to do it right:

  • Use a Plastic Shovel: Metal shovels can scratch the surface of your deck, so always use a plastic shovel to remove snow. So take the time to grab the right tool for the job and skip on the metal tipped shovel you would use for a sidewalk or driveway.
  • Avoid Rock Salt or Deicers: While salt may melt ice quickly, it can be harmful to your deck, especially if it’s made from wood! Salt can cause discoloration, drying, and premature aging of your deck. Instead, opt for a non-toxic, deck-safe ice melt or sand to improve traction without damaging the surface.
  • Shovel Gently: When clearing snow, use gentle strokes to avoid scratching or gouging the deck’s surface. Start at the edges and work your way toward the middle. If the snow is light, you may even consider using a gentle broom before the snow hardens and sticks.

Pro Tip: If you don’t want to worry about shoveling at all, you might consider installing a roof or canopy over your deck, which will reduce the amount of snow accumulation.

3. Protect Your Deck with a Sealant

Winter’s moisture — combined with freezing and thawing cycles — can cause wood to expand and contract, leading to cracking and splitting. One of the best ways to protect your deck during winter is by applying a high-quality sealant or protective coating before the cold weather hits. Preferably, in the spring or fall.

  • Why Sealant Matters: A protective coating helps repel water, prevent rot, and protect against UV damage. It also reduces the absorption of snowmelt and rainwater, which could otherwise seep into the wood and cause long-term damage.
  • Timing Is Key: The best time to apply sealant is in the fall, before temperatures dip too low. Spring is okay too, but this often runs into prime outdoor entertaining season. Don’t worry if you missed these windows though! It’s still a good idea to apply a sealant in early winter or any other time of the year if weather permits.

4. Prevent Winter Damage to Your Deck with Covers

For those particularly harsh winters or if you don’t use your deck during the colder months, a deck cover might be an option worth considering. Covers can shield your deck from snow, ice, and falling debris, preventing excess moisture from building up on the surface. They can also protect the finish and reduce the need for snow shoveling.

Be sure to choose a breathable cover that allows air to circulate, which will prevent mold or mildew growth. A tightly sealed cover might trap moisture underneath, leading to problems. Alternatively, a deck membrane can protect your deck without needing a cover while also enhancing its look and function.

5. Monitor Your Deck Throughout the Winter

Even with proper preparation, it’s important to keep an eye on your deck during the winter months. Extreme cold temperatures and winter storms can cause unexpected damage. Periodically check for:

  • Ice Dams: If you have gutters above your deck, be mindful of ice dams that could form and drip excess water onto the deck surface. This moisture can cause swelling or wood rot. While ice dams are most commonly associated with roofs, they can also affect decks.
  • Structural Integrity: High winds and heavy snow can stress your deck. Ensure the railing and foundation are intact, and keep an eye out for any signs of shifting or instability.

If you spot any issues, address them immediately to avoid costly repairs when the weather warms up.

The Verdict: Winter Deck Care Pays Off

Taking the time to properly care for your deck during the cold winter months not only helps preserve its beauty and functionality, but it can also save you from expensive repairs and replacements in the spring. Inspecting your deck, shoveling snow carefully, applying sealants, and using covers can all make a big difference in protecting your outdoor space.
