No. In most cases, it’s not colder or freezing temperatures that affect decking materials but the amount of moisture that seeps into the materials as a result. For example, wood decking material is more likely to suffer from rot or decay when exposed to excess moisture from snow or ice. An extreme change in temperature can cause wood to expand or contract, but only if it’s not properly treated beforehand.

In most cases, there should be a small gap between the house and the deck, usually no more than ½ to ¾ of an inch. This space allows water and moisture to flow through instead of pooling against the side of your house. It also lets flashing protect your siding from runoff, which is one of the most common issues with decks.

Floating decks are a cost-effective and versatile option, but they come with some compromises. Since they sit on smaller footings instead of being deeply anchored, they’re more likely to shift over time, especially in areas with heavy rainfall or freeze-thaw conditions. Their low-to-the-ground design makes them more susceptible to moisture buildup and potential water damage.

The life expectancy of deck boards varies widely based on the material, climate, and maintenance. Untreated wood boards typically last 10 to 30 years with proper care, while pressure-treated boards can last up to 50 years. Hardwoods generally outlast softwoods. Composite boards also tend to last longer than natural wood. Environmental factors like arid or humid climates can shorten a deck's lifespan. To extend the life of wood decking, it's important to consistently clean and seal it to protect against moisture, UV light, and insects.
