The Best Decking Materials for Minnesota’s Climate

In Minnesota, building a deck means more than creating a beautiful outdoor space — it means selecting materials that can withstand harsh temperature changes, heavy snow, and intense summer sun.

Whether you’re hosting a weekend barbecue or enjoying a quiet coffee outdoors, the decking material you choose matters. The wrong material can lead to warping, cracking, or early deterioration in our challenging climate.

In this guide, we’ll cover the best decking materials for Minnesota’s tough conditions.

Composite vs. Wood: Which Decking Material Performs Best in Minnesota?

Composite decking materials have become a popular alternative to wood in Minnesota due to their superior durability and low maintenance requirements.

Made from a blend of recycled plastics and wood fibers, composite boards resist rot, warping, insect damage, and moisture penetration. Unlike natural wood, composite materials do not require annual staining or sealing, which is especially advantageous during Minnesota's long, wet springs and harsh winters.

On the other hand, traditional wood decking—such as pressure-treated pine, cedar, or redwood—offers a classic look and feel that many homeowners appreciate. However, these materials are prone to weathering over time. Moisture can lead to warping, cracking, or even mold and mildew without proper and regular maintenance. With freeze-thaw cycles in Minnesota, untreated or poorly maintained wood decks may require more frequent and costly repairs.

For Minnesota homeowners seeking longevity with less maintenance, composite often offers a more practical solution. Companies like Olson Construction & Remodeling help homeowners choose high-performance products that maintain their aesthetic and structural integrity across all four seasons.

Their extensive experience in building decks ensures that each installation is tailored to the local climate.

Maintenance Needs for Different Decking Materials

The level of upkeep required varies widely depending on the material. Composite decking is the most maintenance-friendly.

It requires only periodic cleaning with soap and water to remove dirt or mildew buildup. It never needs to be sanded, stained, or sealed, and it resists splintering and color fading, even after years of exposure to UV rays and snow.

Wood decks, by contrast, demand regular attention. Most wood materials need annual staining or sealing to protect against moisture intrusion. During winter, the expansion and contraction caused by freeze-thaw cycles can lead to cracking. In spring and summer, high humidity can accelerate the growth of rot, mildew, or pest infestations if the surface isn’t treated correctly. Homeowners should inspect their deck for loose boards or signs of wear at least twice a year.

When selecting the best material for your climate, it’s essential to strike a balance between maintenance tolerance and aesthetic preferences. In the long term, low-maintenance materials like composite can reduce overall upkeep costs and time commitments.

Designing a Deck That Withstands Minnesota Winters

Decks in Minnesota must be built with winter durability in mind. Snow loads, ice buildup, and repeated freezing and thawing require structural resilience and moisture management.

A critical aspect of design involves using moisture-resistant materials, such as composite or pressure-treated lumber, that are rated for ground contact. The framing should use galvanized or stainless steel fasteners to prevent corrosion over time.

Proper drainage is essential. Deck boards should be spaced to allow melting snow and ice to drain off the surface, reducing pooling and preventing water from freezing and expanding in place. Builders may also recommend sloped framing to direct runoff away from the structure and home foundation. Skirting or lattice work can help block wind-blown snow from collecting beneath the deck, reducing freeze impact on support structures.

While aesthetic design matters, structural integrity is non-negotiable. Designing for Minnesota’s winters means selecting resilient materials and employing professional installation techniques to ensure year-round usability and safety.

Popular Decking Trends Among Minnesota Homeowners

In Minnesota, homeowners are combining function with design to create outdoor spaces that can be used for most of the year.

One trend includes multi-level decks that separate entertainment zones from dining and relaxation areas. Built-in seating and planters are popular for maximizing space and reducing furniture needs.

Lighting integration is also on the rise. LED lights built into stairs and railings improve both ambiance and safety, especially during long winter nights. Composite decking in rich grays, browns, and natural wood tones remains a popular choice, providing modern aesthetics with less upkeep. Railings in contrasting colors or with cable or glass insets are also gaining popularity for a sleek, open look that doesn’t block views of the yard or lake.

Covered decks and pergolas have become common additions, offering shade during summer and making it easier to use the space during spring and fall. These elements contribute to a deck that’s as usable as it is stylish—key for homeowners who want year-round value from their outdoor investment.

Cost Comparison of Decking Materials in Minnesota

The cost of decking materials can vary significantly depending on the type of material and size of the project.

Composite decking generally comes with a higher upfront price—ranging from $30 to $60 per square foot installed—but offers long-term savings in reduced maintenance and longer lifespan. Popular brands like Trex and TimberTech offer warranties of 25 years or more, making them a smart investment for homeowners seeking long-term value.

Wood decking, such as pressure-treated lumber, typically costs less upfront, around $15 to $25 per square foot installed. However, when factoring in the cost of annual maintenance (staining, sealing, and repairs), the long-term expense can exceed that of composite. Cedar or redwood, while more attractive and naturally rot-resistant, can also push prices closer to those of composite materials.

For homeowners weighing their options, it’s essential to calculate the total cost of ownership, rather than just the initial installation price. Olson Construction & Remodeling helps clients understand these long-term differences and tailor material choices to their budgets and performance expectations.
