Fiber Cement or Engineered Wood Siding for Your Ames Home? A Head-to-Head

Fiber cement weighs roughly 2.5 pounds per square foot. Engineered wood siding covering the same wall weighs closer to 1 pound. On a full Ames re-side that is a difference of well over a thousand pounds hanging on your sheathing, and it shapes everything from the fasteners the crew uses to how the panels handle a summer of Iowa humidity swings. If you are weighing fiber cement against engineered wood for a re-side this fall, that weight gap is where the two materials start to part ways.

Both are legitimate, long-lived choices. Neither is a gimmick. But they behave differently on an Iowa home that takes hail, wind, and a 100-degree temperature spread between January and July, so it is worth knowing what you are actually buying.

What each one costs installed in the Ames area

Ballpark numbers first, because that is usually the real question. Installed, fiber cement siding tends to land somewhere around $9 to $14 per square foot in the Ames market, depending on the product line, the trim package, and how much prep the walls need. Engineered wood, meaning the resin-and-wood-fiber boards sold under names like LP SmartSide, usually runs a little lighter, often $8 to $12 per square foot installed.

Say a homeowner is re-siding a 1,900-square-foot two-story on the north side of Ames. In round terms, that is a spread of maybe $17,000 to $27,000 for fiber cement and roughly $15,000 to $23,000 for engineered wood, before you factor in tear-off surprises like rotted sheathing. The gap is real but it is not enormous, and it can flip depending on which trim and finish you pick.

That closeness is the point: this is rarely a decision you make on price alone. You make it on how the material lives on your specific house. For a fuller breakdown of what goes into a re-side number, our siding replacement service page lays out the scope.

Weight, hail, and how they take an Iowa beating

That 2.5-pound-versus-1-pound difference matters most in two places: installation and impact.

Because fiber cement is heavier and more brittle, the crew handles it differently. Boards get supported, cut with the right blades, and fastened on tighter spacing. Done right, that mass is an asset. Fiber cement shrugs off dime-sized hail that would dent softer materials, and it does not feed a fire. If you want the longer version of how it holds up to hail, we walked through that in “Is Fiber Cement Siding Worth It on an Iowa Home That Takes Hail?”

Engineered wood is lighter and more forgiving to carry and cut, and it has real impact toughness of its own. In a bad hailstorm it can bruise or crack rather than shatter, and the resin binder resists the kind of splitting you would see in old-fashioned hardboard. Say a storm drops golf-ball hail across a west elevation. Both materials can survive it, but the failure modes differ: fiber cement is more likely to chip at edges, engineered wood more likely to dent or gouge. Either way, your insurer cares about the damage, not the brand, which is worth remembering when you file. We covered how impact claims work in our storm and insurance walk-through.

Moisture and freeze-thaw: the Iowa deciding factor

This is where a lot of Ames re-sides get decided. Our climate throws water at siding constantly, then freezes it, then bakes it.

Fiber cement is essentially cement, so it does not rot and it does not swell. Its weak point is the caulk and paint at joints, which need to stay maintained, and its bottom courses if they sit too close to grade and wick moisture. We wrote a whole piece on that failure, “Soft, Swollen Bottom Courses,” because it is a preventable problem the crew handles with proper clearance and flashing.

Engineered wood is treated to resist moisture and comes factory-primed, and quality installs hold up well. But it is still wood fiber at the core. If a cut edge goes unsealed, or flashing fails, water can eventually find the fiber and cause swelling. Fiber cement gives you a little more margin against a small detail being missed. For a home where you plan to stay 20-plus years and want the lowest-worry envelope, that margin is often what tips people toward fiber cement.

Looks and upkeep over the long haul

Both materials come in lap, shake, and vertical panel profiles, and both can be had factory-finished or ready for paint. Engineered wood tends to show a slightly deeper wood-grain texture that some Ames homeowners love. Fiber cement can be had in crisper, more architectural profiles.

Upkeep is similar in spirit: rinse the walls, keep the caulk sound, and repaint when the finish dulls, typically on a 10-to-15-year cycle for a quality factory coat. Fiber cement’s finish warranties often run long, and we broke down what those actually cover in “What Fiber Cement Siding Warranties Really Cover.”

If you are still torn, the honest answer is that both are good when installed well, and the seams and details matter more than the label. That is the whole reason to use a crew that does siding and only siding. Want a second opinion on which fits your house and budget?

Frequently Asked Questions

Can I mix fiber cement and engineered wood on the same house?

It is possible but rarely worth it. Different expansion rates and fastener needs make the transition details fussy, and matching the paint sheen across two materials is a headache. If you want a mixed look, most Ames crews get it with two profiles of the same material instead, say lap on the main walls and shake in the gables.

Does one hurt resale value more than the other?

Both read as premium upgrades to a buyer over old vinyl or aluminum. Appraisers in the Ames market generally treat quality fiber cement and quality engineered wood similarly. What actually moves resale is a clean, well-detailed install, not the brand on the box.

My house has failing 1970s siding. Does the old material change which I should pick?

Not directly, but tear-off can. Older walls sometimes hide rotted sheathing or missing housewrap, and lighter engineered wood is a touch easier to hang on questionable substrate while repairs happen. Either way, budget for what the tear-off reveals before you lock in a material.

Is engineered wood a good pick if I might move in five years?

For a shorter stay, either material is more house than you strictly need, and the lower up-front cost of engineered wood can make sense. For a long-term home in Iowa’s freeze-thaw climate, fiber cement’s moisture margin often wins out.
