LP SmartSide vs. Vinyl Siding for Iowa Homes

Vinyl usually costs less to finish and never needs paint, while LP SmartSide engineered wood gives a real board look and stronger hail results in LP's own testing, but it needs paint over time. We install both, so the right pick comes down to budget, the look you want and how long you plan to stay.

What each one is made of

LP SmartSide is engineered wood. LP treats every board with its SmartGuard process, which uses resins, water-resistant waxes and zinc borate to fight moisture, termites and fungal decay. Its 38 Series lap comes in 16 foot lengths, 3/8 inch nominal thickness, in cedar texture or smooth. Vinyl siding is a thin, flexible panel that hangs loose on its nails so it can move with the temperature. Thickness varies by line: Alside lists its Charter Oak panel at .046 inch, and its Prodigy insulated siding adds a 1-1/2 inch EPS foam backer attached to the panel. Those differences matter more than the word on the box.

Cost side by side

Angi's October 2026 siding guide lists material costs of $3 to $12 per square foot for vinyl and $1 to $6 for engineered wood such as LP, plus $1 to $4 per square foot for labor. Those numbers leave out finish. Primed LP SmartSide needs a 100 percent acrylic exterior paint, which adds a painting step, while LP's ExpertFinish boards come prefinished. Vinyl is done the day it goes up. Your actual price comes from a free estimate that compares both products on your walls.

Hail, wind and Iowa cold

The National Weather Service calls hail severe at 1 inch, about quarter size. LP says third-party testing it commissioned found its cedar texture lap resists hail better than fiber cement and vinyl, and LP's published coverage terms for SmartSide include hail impacts up to 1.75 inches, golf ball size. LP also rates its lap for wind gusts up to 200 mph. Vinyl has a cold weakness: Angi notes it can become brittle and break in extremely cold temperatures, and the vinyl industry's install manual calls for wider gaps when installing below 40 degrees. Alside adds impact modifiers to Charter Oak for dents and dings. Read each maker's terms before you choose.

Moisture and install details that matter

Both products fail early when water gets behind them. LP's instructions call for at least 6 inches of clearance between siding and finished grade, 1 inch above roofing, a water-resistive barrier, metal flashing above openings and a seal on every cut end. Vinyl needs a 1/4 inch gap at corner posts and J-channel, raised to 3/8 inch below 40 degrees, and nails left about 1/32 inch loose so the panel can slide. A rushed crew that nails vinyl tight or leaves LP cut ends bare causes many of the problems people blame on the material. Working seamless gutters matter too, because overflow soaks the walls below.

Paint, color and upkeep

LP's 2026 catalog lists 16 ExpertFinish colors, from Snowscape White to Garden Sage and Abyss Black, and says primed boards take paint well and can be repainted over time. That gives you any color you want, and a chance to change it later. Vinyl color is baked in. Alside lists 29 colors for Charter Oak and says you will never have to stain or paint it again, and Angi notes vinyl cleaning is simple enough for a beginner. Plan on caulk and paint touch-ups with LP over the years, and on washing with either one.

Lifespan and resale

Angi gives vinyl and engineered wood the same typical life, about 20 to 40 years, and says the real number depends on installation and upkeep. The 2025 Cost vs Value report's Des Moines page tracks a vinyl re-side at 68.6 percent of cost recouped at resale, but it has no engineered wood line, so there is no local resale number for LP. In plain terms, neither one is the long-life winner on paper. Pick the look and upkeep you want, then make sure the wrap, flashing and gutters under and around it are done right.

Which one fits your house

Vinyl often makes sense on rentals, on long ranch walls where budget rules, and for owners who never want to paint. LP SmartSide fits homeowners who want a deep board shadow line, a painted color that can change later, or tougher boards on a hail-exposed wall. Some houses use both: vinyl on the body with LP trim around windows and corners.
