LP SmartSide Siding: Pros, Cons, and Is It Right for Minnesota Homes?
LP SmartSide is one of the most popular siding choices among Minnesota homeowners right now, and for good reason. It handles cold winters well, holds paint better than most wood products, and installs faster than fiber cement. But it is not the right choice for every home or every budget.
This guide covers the real pros and cons of LP SmartSide, how it performs in Minnesota’s freeze-thaw climate, how it stacks up against James Hardie fiber cement, and what you can expect to pay for an installation in the Twin Cities metro and greater Minnesota area.
What Is LP SmartSide Siding?
LP SmartSide is an engineered wood siding product manufactured by Louisiana-Pacific. Unlike traditional wood siding, it is made from wood strands bonded with a resin adhesive and treated with LP’s proprietary SmartGuard process, which incorporates four components throughout the entire product: adhesive resins, water-resistant waxes, zinc borate preservative, and a resin-saturated overlay bonded to the surface. This treatment runs through the core of the panel, not just the face.
The result is a product that looks like real wood, accepts paint the same way real wood does, but resists moisture, fungal decay, and insects far better than natural wood siding. It is available in lap siding, vertical panels, soffit, fascia, and trim profiles, making it a full exterior system rather than just a siding product.

Pros of LP SmartSide Siding in Minnesota
1. Engineered for Cold, Wet Climates
LP SmartSide was not adapted for cold climates as an afterthought. It was originally engineered with northern climates in mind. The zinc borate component of the SmartGuard treatment runs through the entire product, not just the surface, which means moisture penetration from freeze-thaw cycling does not reach untreated wood fiber. According to LP’s own product documentation, the SmartGuard process specifically helps the product withstand damage from freeze-thaw cycles and high humidity. Minnesota homeowners who have had problems with wood siding warping, cupping, or rotting after harsh winters tend to find LP SmartSide a significant upgrade.
2. Exceptional Impact Resistance
According to LP’s product specifications, LP SmartSide lap siding is designed to withstand wind gusts of up to 200 miles per hour. The warranty also covers hail damage up to 1.75 inches in diameter when properly installed and maintained. In Minnesota’s hail season, which runs roughly from May through September and produces some of the highest hail frequency in the country, this matters. Many Minnesota homeowners have filed successful insurance claims after hail events where LP SmartSide showed damage. The product’s documented impact performance makes the claims process more straightforward.
3. Outstanding Warranty Coverage
LP SmartSide is backed by what LP calls its 5/50 limited warranty: the first five years provide 100% labor and material replacement coverage, followed by a 50-year prorated limited warranty on the substrate. The warranty is transferable to subsequent homeowners, which adds real value if you plan to sell. It also covers termite damage, fungal decay, and hail damage up to 1.75 inches in diameter. For comparison, most vinyl siding warranties run 20 to 40 years depending on the manufacturer and product tier.
4. Superior Paint Adhesion and Finish Longevity
LP SmartSide accepts paint the same way natural wood does, which means it holds paint significantly longer than fiber cement or vinyl. The factory prime coat is designed to accept any acrylic latex topcoat. Most manufacturers and contractors recommend repainting LP SmartSide every 8 to 12 years under normal conditions. In Minnesota, given the UV intensity in summer, temperature extremes, and the physical stress of winter on exterior finishes, budgeting for repainting every 8 to 10 years is prudent. If you prefer a prefinished option that skips the initial paint step, LP now offers LP SmartSide ExpertFinish, which comes factory-finished in 16 colors and carries an additional 15-year finish warranty on top of the 5/50 substrate warranty.
5. Lighter and Faster to Install Than Fiber Cement
According to LP, LP SmartSide lap siding installs up to 25% faster than comparable fiber cement and weighs up to 39% less per square foot. This weight difference matters for installation speed and labor cost. LP SmartSide can also be cut with standard woodworking tools, whereas fiber cement requires specialty blades and generates silica dust that requires respiratory protection. Faster installation with standard tools means lower labor cost in most cases, and that savings is typically reflected in the total project price.
6. Real Wood Aesthetic
LP SmartSide looks like wood because it is made from wood. The grain texture is natural rather than embossed, which gives it a depth that vinyl siding and some fiber cement profiles cannot fully replicate. For neighborhoods with architectural character or HOA requirements that specify a wood-look siding, LP SmartSide satisfies the visual standard while outperforming natural wood on durability.
Cons of LP SmartSide Siding
1. Moisture Vulnerability at Cut Edges and Penetrations
The SmartGuard treatment protects the manufactured surface and core of the board, but cut edges expose raw wood fiber that is more moisture-vulnerable. LP’s installation guidelines require field-applied end-cut sealant at every cut, proper flashing at all windows, doors, and penetrations, and a minimum ground clearance of 6 inches. When these steps are skipped or done poorly, moisture can wick into cut ends and cause swelling, delamination, or decay over time. This is an installation quality issue as much as a product issue, which is why choosing an experienced installer matters as much as choosing the product itself.
2. Requires Regular Painting
LP SmartSide ships primed but not finish-painted (unless you choose ExpertFinish). You will need to apply a topcoat at installation and repaint every 8 to 12 years. If you prefer a low-maintenance exterior that never needs painting, fiber cement with a factory finish such as James Hardie’s ColorPlus, or quality vinyl siding, are worth considering. For many homeowners the ability to change color at each repainting cycle is a benefit; for others, the maintenance schedule is a drawback.
3. Higher Cost Than Vinyl
LP SmartSide costs more than vinyl siding in both materials and total installed cost. However, it is generally less expensive than fiber cement on a total installed basis in most Minnesota markets. See the cost section below for current estimates.
4. Not as Moisture-Proof as Fiber Cement
Fiber cement is a non-organic material. It does not absorb moisture under any conditions. LP SmartSide is an engineered wood product and, while treated, is not fully impervious to moisture the way fiber cement is. Homes with chronic moisture exposure from irrigation spray, snowmelt pooling at the base, or north-facing walls that rarely dry out may show earlier wear on LP SmartSide than on fiber cement if the installation and flashing are not executed carefully.
LP SmartSide vs. James Hardie: Side-by-Side Comparison
The most common question homeowners ask when considering LP SmartSide is how it compares to James Hardie fiber cement. Both are excellent products widely used in Minnesota. The right choice depends on your priorities.

Is LP SmartSide a Good Choice for Minnesota Homes?
For most Minnesota homes, yes. The combination of freeze-thaw durability, 200 mph wind resistance, hail warranty coverage, 5/50 warranty, and natural wood appearance makes LP SmartSide one of the strongest value propositions in the siding category for this climate.
Minnesota’s weather puts siding through more stress than most other states. Temperatures swing from -30°F in winter to 95°F in summer, a range of more than 120 degrees. Siding products expand and contract with those swings repeatedly for decades. LP SmartSide is engineered to handle that thermal cycling. Its zinc borate treatment means that when snow melts against the base of the siding or spring rains hit repeatedly, the product is not silently absorbing moisture and degrading the way untreated wood does.
LP SmartSide is particularly well suited for homes in the Minneapolis-St. Paul metro, Monticello, Rogers, Elk River, Coon Rapids, and surrounding communities where hail events are common and homeowners are often replacing siding after storm damage. The product’s documented impact ratings and warranty hail coverage make it easier to work with insurance adjusters, and give homeowners confidence that the new siding will hold up through future storm seasons.
Where LP SmartSide may not be the first choice is on homes with chronic moisture issues, such as siding facing north with no sun exposure and consistent snow contact throughout winter, or homes with known drainage problems near the foundation. In those situations, fiber cement or a premium vinyl product may be more appropriate. A Perfect Exteriors consultant can assess your specific conditions and help you decide.
What Does LP SmartSide Cost in Minnesota?
LP SmartSide installation costs in Minnesota typically range from $8 to $13 per square foot installed, depending on the profile selected, the complexity of the home’s exterior, and current labor rates. A 2,000-square-foot home with a straightforward exterior might run $16,000 to $24,000 for a full re-siding project. Homes with multiple gables, dormers, complex trim work, or significant existing siding removal will run toward the higher end.
Factors that affect the total cost include:
- Profile selected – lap siding, vertical panels, and shake profiles vary in price per square foot
- Whether existing siding needs to be removed or the new siding can be overlaid
- Condition of the housewrap and sheathing underneath
- Number of windows, doors, and penetrations requiring trim and flashing
- Whether you choose standard primed LP SmartSide or the ExpertFinish prefinished product
LP SmartSide is generally less expensive than a full James Hardie installation, typically by 15 to 25 percent on the total project cost, while offering a longer warranty period. For homeowners replacing storm-damaged siding, insurance proceeds often cover a significant portion of the project cost.

Frequently Asked Questions About LP SmartSide in Minnesota
How long does LP SmartSide last in Minnesota?
With proper installation and regular repainting on schedule, LP SmartSide routinely lasts 30 to 50 years in Minnesota’s climate. The 50-year prorated substrate warranty reflects LP’s confidence in the product’s longevity. The most common reason for early failure is improper installation, specifically unsealed cut ends or inadequate flashing at window and door penetrations, rather than product failure itself.
Does LP SmartSide hold up to Minnesota winters?
Yes. LP SmartSide’s SmartGuard process specifically addresses freeze-thaw cycles. The zinc borate treatment and resin binders run through the entire core of the product, protecting against moisture infiltration even when snowmelt saturates the base of the wall repeatedly through a Minnesota winter. Homeowners across northern Minnesota and the Twin Cities metro have used LP SmartSide for decades without the swelling, cupping, or rot issues common to untreated wood siding.
Can LP SmartSide be installed in winter in Minnesota?
LP SmartSide can be installed in cold weather, though most contractors recommend temperatures above 20°F during installation for proper fastener seating and end-cut sealant performance. Many Minnesota contractors complete LP SmartSide projects into late fall. Finish paint application, however, requires temperatures above 50°F, so the topcoat is typically deferred to spring if the installation happens in October or November.
How often does LP SmartSide need to be repainted?
LP SmartSide should be repainted every 8 to 12 years under normal conditions. In Minnesota, given UV intensity in summer, temperature extremes, and the physical stress of winter on exterior finishes, budgeting toward the 8 to 10 year end of that range is the more prudent approach. Using a high-quality 100% acrylic latex exterior paint in a satin or semi-gloss sheen will extend the repaint cycle and provide better moisture resistance than flat finishes.
Is LP SmartSide better than James Hardie for Minnesota homes?
Both are strong products and both are widely installed in Minnesota. LP SmartSide has a longer and stronger warranty (5-year full coverage + 50-year prorated vs. Hardie’s 30-year), installs faster and at lower labor cost, and is warranted against hail damage. James Hardie is a non-organic material that is fully impervious to moisture under any conditions, and its ColorPlus factory finish can extend the repaint cycle to 15 years. For most Minnesota homeowners, LP SmartSide delivers comparable performance at a lower price point. The best choice depends on the specific conditions of your home, your maintenance preferences, and your budget.
Does LP SmartSide qualify for insurance replacement after hail damage?
Yes. LP SmartSide is covered under standard homeowners insurance policies for hail damage the same as any other siding material. Notably, LP’s own warranty covers hail damage up to 1.75 inches in diameter when the product is properly installed and maintained, which is a separate layer of protection beyond your homeowners policy.
