This particular page is a pure material comparison; there is no lead form on it, and nothing on this page routes you to one.
I do not make "best installer in [city]" recommendations and I do not rank contractors. Sourced specs and warranty extractions below; nothing here is hands-on testing.
Why "which siding is best" is the wrong question
Every siding-comparison page you'll find ranks materials on an overall winner — usually fiber cement, with vinyl as the budget pick and wood as the high-maintenance premium option. That framing hides the thing that actually matters once you own the house: what happens when something goes wrong, and who pays for it. A "lifetime warranty" on vinyl siding and a "50-year warranty" on engineered wood sound like comparable promises. Read the actual documents and they aren't — one is a percentage-based proration schedule that decays starting in year six, the other pays material cost only after year five and caps those payments at twice what you paid, and a third pays a declining per-square-foot amount that hits zero after fifteen years for one specific type of damage. None of that is disclosed anywhere a search snippet would show you. Vinyl siding cost in 2026 examines the per-square price and the CertainTeed and Mastic warranty clauses in more detail. Cedar siding cost in 2026 compares profiles, lumber grades, maintenance intervals and local WUI restrictions. Metal siding cost in 2026 compares installed steel and aluminum prices, named finishes, and manufacturer hail and corrosion exclusions. Board and batten siding cost in 2026 compares installed material ranges, vertical panel seams, and HardiePanel, LP SmartSide, and Mastic warranty terms. Stucco siding cost in 2026 compares installed three-coat, one-coat, and EIFS estimates with LaHabra assembly warranties and Seattle drainage requirements.
So instead of picking a winner, this page does three things: a comparison table across five materials on six properties, each cell sourced to a document I actually opened; a plain-English translation of what each manufacturer's warranty PDF actually promises and where its teeth are missing; and a California building-code section that rules one common material out entirely in a specific set of jurisdictions, which no marketing page for that material will tell you.
The comparison table
Five materials, six properties. The cost and lifespan cells are disprovable — click the link and check whether the source still says what I claim. The warranty cells are the ones a scraper couldn't produce: I pulled three manufacturer warranty PDFs directly rather than relying on a dealer's summary of them.
| Property | Vinyl | Fiber cement (James Hardie) | Engineered wood (LP SmartSide) | Aluminum | Natural wood / cedar |
|---|---|---|---|---|---|
| Installed cost, national aggregate | $6.13/sq ft (This Old House, retrieved 2026-09-27) | $9.00/sq ft (This Old House, retrieved 2026-09-27) | Not broken out separately by any national aggregator we found; regional sources cluster it $3–$12/sq ft, overlapping vinyl at the low end and fiber cement at the high end (see Siding Replacement Cost 2026) | $7.32/sq ft (This Old House, retrieved 2026-09-27) | $11.70/sq ft, cedar (This Old House, retrieved 2026-09-27) |
| Expected lifespan | 20–40 years is the common regional-contractor range (see companion cost article); manufacturer warranties run to "lifetime" for the original owner only (see below) | 30-year limited product warranty for the HZ10 products listed in the document (James Hardie warranty PDF, retrieved 2026-09-30, primary-document extraction) | Manufacturer's own warranty document is titled a "Prorated 50-Year Limited Warranty" (LP SmartSide warranty PDF, retrieved 2026-09-27, primary-document extraction) — but "50-year" and "50-year prorated at 2.22%/year, material only" are not the same promise; see below | 30–40 years "with proper maintenance," some products carrying "limited lifetime" finish warranties (Fixr, "Aluminum Siding Guide 2026," published 2026-02-13, retrieved 2026-09-27) | — |
| Warranty structure (read from the actual PDF) | Lifetime, non-prorated, but only for the original individual owner of a single-family home. Every other owner — including the very next buyer of the house — gets a prorated 50-year warranty that steps down from 100% (years 0–5) to 10% (years 14–50) (CertainTeed Vinyl Siding Products Lifetime Limited Warranty, effective 03/01/2026, retrieved 2026-09-27, primary-document extraction) | 30-year HZ10 product warranty; separately, the 15-year ColorPlus finish warranty caps cash reimbursement at $1.00 per sq ft in year one, declining 6.67% per year, reaching $0 after year 15 (James Hardie ColorPlus warranty PDF, retrieved 2026-08-08, reused) | Years 1–5: full labor-and-material repair or replace, valued using the RSMeans construction-cost index. Years 6–50: material cost only (no labor), prorated at 2.22% per year, and those year 6–50 payments are capped in total at 2× the original purchase price (LP SmartSide warranty PDF, retrieved 2026-09-27, primary-document extraction) | — | Typically no manufacturer product warranty at all; it's a natural material, not a manufactured assembly, so warranty coverage (where it exists) usually applies to a factory finish/stain, not the wood itself |
| What voids or limits the warranty | Painting, varnishing, or refinishing the product voids the warranty unless CertainTeed authorizes it — the opposite requirement of engineered wood (CertainTeed PDF, retrieved 2026-09-27) | Mold, mildew, "any organism," third-party paint/coatings, and normal fade/chalk are all expressly excluded; natural disasters including hurricanes and exceeding designed wind loads are excluded from the 30-year HZ10 product warranty (Sections 2 and 5; retrieved 2026-09-30) | The opposite of vinyl: field-painting exposed cut edges is a condition of keeping the warranty, not an option — LP's installation instructions state failure to follow application instructions "could result in… denial of coverage" (LP SmartSide installation instructions, retrieved 2026-08-08, reused) | Not independently verified this session | Moisture intrusion behind a failed paint/stain seal accelerates rot; this is a maintenance failure, not usually a manufacturer exclusion, because there is typically no product warranty to void |
| Hail damage | Warranted, but only as a secondary payer: the homeowner must first file an insurance claim, and CertainTeed pays only the gap between the insurer's payment and the repair cost, excluding the deductible and never exceeding the value of the damaged product (CertainTeed PDF, retrieved 2026-09-27, primary-document extraction) | The HZ10 product warranty expressly includes resistance to hail damage (Section 1; retrieved 2026-09-30) | Covered under a specific "Hail Damage" definition — a crack, chip, or dent exceeding 3/8 inch — but excluded entirely for hailstones larger than 1.75 inches in diameter (LP SmartSide warranty PDF, retrieved 2026-09-27, primary-document extraction) | Dent-prone; Fixr notes aluminum is "a soft metal, which makes it prone to dents" from hail and debris (retrieved 2026-09-27) | Not typically a named warranty category |
| Wildfire/WUI code eligibility (see below) | Not listed as a compliant material under California's ignition-resistant exterior-wall-covering requirements in the state's wildland-urban-interface building code | Noncombustible; compliant | Engineered wood is a treated wood product; compliance depends on the specific tested assembly, not the material class generically — check the product's listing, not the marketing page | Metal siding is frequently marketed for wildfire-prone regions; Fixr specifically calls it "one of the best siding materials for homes in wildfire-prone states" (retrieved 2026-09-27) | Untreated natural wood does not qualify without a tested ignition-resistant assembly |
What the warranty documents actually say, past the table
CertainTeed's vinyl warranty: lifetime is a one-owner promise
I read CertainTeed's current Vinyl Siding Products Lifetime Limited Warranty directly (effective for installs on or after March 1, 2026 — the document confirms the version we pulled is the live one). Three things in the PDF don't show up in "lifetime warranty" marketing copy:
- The non-prorated lifetime coverage belongs to one specific person: the original individual owner of the single-family home it was installed on. Everyone else — a subsequent buyer of the house, an HOA, a landlord, a school, a church — is covered by a prorated 50-year warranty measured from the original install date, stepping down from 100% coverage (up to 5 years) to 10% coverage (14 to 50 years). If you buy a house with 12-year-old vinyl siding, you are already down to roughly 30% coverage on day one of ownership, under this schedule, regardless of how the siding looks.
- Fade coverage is separately non-transferable, even when the rest of the warranty transfers. The document states plainly: "The fade protection coverage of this Warranty is not transferable." A home buyer inherits the structural/defect warranty on a prorated basis but not the fade warranty at all.
- Excess fade has a specific, numeric definition: a color change "greater than four (4) Hunter units," measured per ASTM D2244. That is a different standard and a different unit than James Hardie's ColorPlus warranty, which defines excess color change as "greater than four (4) delta E units" — the two brands both use "4 units" as their threshold, but Hunter units and delta E are not the same measurement, so the two numbers are not directly comparable despite looking identical on the page.
(Source: CertainTeed LLC, "Vinyl Siding Products Lifetime Limited Warranty," effective date 3/1/26, retrieved 2026-09-27 — primary-document extraction. This document was not extracted in the companion cost article, which explicitly flagged CertainTeed's warranty as not independently verified; this page closes that gap.)
LP SmartSide's "50-year warranty" is a 5-year warranty with a 45-year afterthought
The LP SmartSide Prorated 50-Year Limited Warranty and Arbitration Agreement, read directly from the current PDF (effective for purchases on or after 08/01/2025), is structured in two very different pieces:
- Years 1 through 5: LP will "repair or replace the affected Product, including the reasonable cost of labor and material, as established by independent construction cost estimator RSMeans." Full coverage, both labor and material.
- Years 6 through 50: LP will "compensate the Owner for the material cost of the affected Product or a similar wood-based siding or trim product (no labor or other charges shall be paid) less an annual pro-rata reduction of 2.22% per year (for example, 6th year – 2.22%, 7th year – 4.44%, etc.)." No labor. And the total LP will ever pay out under this section, years 6 through 50, is capped at two times the original purchase price of the affected product — a hard ceiling that a "50-year warranty" headline gives you no reason to expect.
- Hail damage is a named category with a hard upper limit. Damage is covered only if it's a crack, chip, or dent larger than 3/8 inch, and coverage is void outright for "any damage caused by a storm in which hail was larger than 1.75 inches (45 mm) in diameter" — a specific, disqualifying hailstone size stated nowhere on LP's product marketing pages.
- The warranty is arbitration-bound. The document opens with: "BY INSTALLING AND/OR RETAINING THE PRODUCT, OWNER AGREES TO THE FOLLOWING TERMS AND CONDITIONS OF THIS LIMITED WARRANTY WHICH REQUIRE BINDING ARBITRATION AND WAIVING CLASS ACTION CLAIMS."
Put plainly: the headline "50-year" is true as a document title, but the economically meaningful warranty — full labor-and-material coverage — is five years. The next forty-five years pay a shrinking fraction of material cost only, capped at 2x what you paid, which is a real but much smaller promise than "50-year warranty" implies on its own.
(Source: Louisiana-Pacific Corporation, "LP® SmartSide® Prorated 50-Year Limited Warranty and Arbitration Agreement – Exterior Use," effective 08/01/2025, retrieved 2026-09-27 — primary-document extraction.)
The James Hardie ColorPlus finish warranty (reused from the companion article)
The companion cost article already extracted this one, and it belongs in this table rather than being re-derived: the 15-year ColorPlus finish warranty caps cash reimbursement at $1.00 per square foot in year one, declining 6.67% annually, reaching $0 after year 15 — the manufacturer's own ceiling on the worst-case finish repair, not visible on any marketing page (James Hardie ColorPlus Technology Express Limited Finish Warranty, document HS12121 04/19, retrieved 2026-08-08, reused from Siding Replacement Cost 2026).
The wildfire code section that quietly rules out one common material
This is the region-specific fact a national comparison page won't carry, because it only binds in one state and only in certain jurisdictions within it. I pulled the actual code text rather than a summary.
California's building code for construction in wildland-urban interface (WUI) fire hazard severity zones has historically been Chapter 7A of the California Building Code. I confirmed directly (up.codes' listing for the 2025 California Wildland-Urban Interface Code, Title 24, Part 7, retrieved 2026-09-27) that a new, standalone California Wildland-Urban Interface Code took effect January 1, 2026; industry sources describe it as consolidating the former Chapter 7A, the California Residential Code's Section R337, and Fire Code Chapter 49 into one code, though I could not independently verify that consolidation language from the code's own text during this session (see "What we could not verify"). Chapter 7A remains the correct citation for projects permitted before that date, and its exterior wall covering section — titled "Materials and Construction Methods for Exterior Wildfire Exposure" and numbered 707A.3 — is the section that matters for siding. It permits exactly three categories of exterior wall covering material:
- Noncombustible material;
- Ignition-resistant material, "labeled for exterior use," tested to the code's ignition-resistant material standard; or
- Fire-retardant-treated wood, labeled for exterior use and meeting the wood-treatment standard referenced elsewhere in the building code.
Standard vinyl siding is not listed as compliant under any of the three categories, because it does not carry the ignition-resistant material test rating the code requires — a threshold tied to a flame-spread performance standard (ASTM E84 / UL 723) that ordinary PVC vinyl siding is not tested or labeled to meet. Fiber cement is noncombustible and clears the first category outright. This means that in a California jurisdiction mapped into a designated Fire Hazard Severity Zone, a straightforward vinyl re-side may not be a code-legal option at all, regardless of what a national aggregator's "vinyl is the value pick" framing suggests — the homeowner has to check the state's Building Materials Listing for an approved product in the "Exterior Sidings and Sheathings" category, not just call a vinyl installer.
This is exactly the kind of fact This Old House's national cost guide or a "vinyl vs. fiber cement" listicle has no reason to carry: it is true only for a subset of homes in one state, it changes which materials are even legal to bid, and it only shows up if you open the actual code section instead of a marketing comparison.
Vinyl siding
Homewyse's September 2026 vinyl siding model starts at $7.59–$12.94 per square foot installed for basic, readily serviceable work. Peak & Valley Roofing's January 2026 Northeast Ohio guide publishes $4–$12 per square foot installed. These are different planning references, rather than matched local bids or installed prices for a named product line.
Vinyl fits a project where you want a manufactured cladding without routine repainting and can specify a suitable profile, color, and accessory package. Ask the bidder to identify the product line, profile, and color alongside the measured exterior walls. Settle wall area versus floor area before multiplying any unit price: the home's indoor living area does not measure its siding.
The caveat is scope. Homewyse treats old-siding removal as an option and excludes permits, tax, hidden framing repair, and general contractor supervision. Ask for old-siding removal and disposal explicitly. Also identify warranty labor: a product remedy does not automatically pay to remove and reinstall siding.
Insulated vinyl siding
Angi's insulated-vinyl guide, updated September 17, 2026, gives $4,000–$12,000 for 1,000 square feet of exterior wall. Dividing those project totals gives $4–$12 per square foot installed, a calculated allowance rather than a quoted unit price. HomeGuide's visibly dated January 28, 2025 guide lists $6–$12 per square foot installed for insulated vinyl; that older national estimate remains dated context.
Foam-backed vinyl fits when you want an integrated siding-and-backing product and have compared it with standard vinyl over any separately proposed insulation. Request the exact profile and its profile-specific R-value, with the wall layers and window transitions drawn. A foam thickness or the word premium does not establish the performance of the completed wall.
The caveat is the installed premium. These overlapping publisher ranges do not measure an upgrade on the same house. Angi's opening prose also has an apparent unit error; the calculated allowance above uses its expressly labeled exterior-wall project table. Price both alternatives against identical removal, repair, flashing, trim, and cleanup scope.
Vinyl shake and polymer shingle siding
RemodelingExpense's vinyl guide, updated July 5, 2026, lists $9–$16 per square foot installed for vinyl shake and $6–$10 for basic lap. Its Cedar Impressions guide, updated June 18, 2026, gives $10–$15 per square foot installed for that polymer shake-style category. These are national publisher planning estimates, not manufacturer offers or matched contractor bids.
Shake-style panels fit when you want a wood-shingle appearance on the whole exterior or selected gables and accent walls. Have the proposal mark exactly which elevations receive the pattern. Specify material and profile, course exposure, color, and the starter, corner, and receiving-pocket accessories. Keep the finished coverage separate from the quantity ordered for cuts.
The caveat is the material label. CertainTeed's Northwoods sheet, marked ©01/26, identifies PVC; its Cedar Impressions sheet, marked ©01/2026, identifies modified polypropylene copolymer. Calling both vinyl shake hides a real product distinction. Require the ordered resin and governing installation instructions instead of assuming visually similar panels share accessories or movement details.
Fiber cement siding
Homewyse's September 2026 fiber cement model puts basic installed work at $9.32–$15.28 per square foot. Cornerstone Renovations' 2026 Portland Hardie guide publishes $15–$25 per square foot of wall area for a broader local scope including tear-off, wall preparation, flashing, trim, and cleanup. Neither range is a quote for your elevations or a universal brand price.
Fiber cement fits when its appearance and documented assembly suit the project and you are prepared to specify the finish and installation details. Ask for factory finish versus field paint, identifying who supplies and completes each coating operation. Request wall area, not floor area, with openings and gables shown on the takeoff.
The caveat is the full wall assembly. Homewyse models favorable basic conditions, lists removal as an option, and excludes permits, tax, hidden framing repairs, and supervision. A lower modeled rate can therefore buy less work than the Portland contractor's range. Compare complete preparation, flashing, finish, and cleanup descriptions, then ask who pays replacement labor under the selected warranty.
Metal siding
Fixr's metal-siding guide, updated April 2, 2026, publishes $7–$16 per square foot installed for coated or painted steel, $4–$12 for Galvalume steel, and $3–$18 for aluminum. These are national budgeting categories based on exterior wall area, not dealer prices for Alside or Rollex lines. Keep the finish category attached rather than blending the steel rows into one price.
Metal fits when you want a specified steel or aluminum panel and its appearance, coating, and maintenance obligations suit the site. Ask for measured wall area and a panel specification identifying thickness or gauge, profile, coating, and accessories. Have alternatives cover the same removal, repairs, trim, and access before comparing their totals.
The caveat is that finish and damage protection depend on the ordered product. Ask for the hail remedy and corrosion exclusions, including salt-spray and dissimilar-material conditions that affect the address. A limited finish warranty does not promise unchanged color or automatically pay installation labor. Keep the governing warranty beside the panel specification so a coating substitution remains visible.
Stucco siding
CountBricks' February 3, 2026 U.S. estimate lists $6–$9 per square foot installed for traditional three-coat stucco over wood framing, $8–$12 for one-coat with acrylic finish, and $9–$13 for EIFS insulated finish. Its scope includes standard labor and materials at average wall heights, excluding sheathing repair and custom textures. These proprietary-database estimates do not price a named LaHabra assembly.
Stucco fits when you want a continuous rendered exterior and have selected the complete assembly, finish, and drainage approach for the existing wall. Ask the estimator to distinguish a finish recoat from removal and replacement of the underlying system. Record the measured wall area and which layers remain.
The caveat is retained scope. The same source gives $3–$8 per square foot installed for re-stucco over existing substrate; that is not a tear-off-and-rebuild allowance. A cheaper recoat can leave preparation and concealed damage unresolved. Request the drainage detail, opening transitions, and issued warranty for the exact components before treating any installed range as the complete wall budget.
Board and batten siding
Heritage Exteriors' January 20, 2026 Northern California guide publishes installed estimates of $5–$9 per square foot for vinyl, $9–$16 for James Hardie fiber cement, $7–$13 for LP SmartSide engineered wood, and $10–$18 for real cedar. These are regional contractor planning ranges, not matched prices for the manufacturer configurations or your walls.
Board and batten fits when a vertical pattern suits the elevations and you have chosen the underlying material separately. Request a measured wall area and a drawn batten layout around windows, corners, and changes in height. Price the panels, battens, accessories, and finish together; the appearance alone does not identify the assembly being purchased.
The caveat is horizontal seams. Different panel systems have different flashing, movement, and seam requirements, so a continuous decorative batten arrangement cannot replace the selected manufacturer's instructions. Ask the installer to show where water drains at each interruption and assign finish responsibility for exposed cuts and field painting. Keep that drawing and the specified material with the accepted total.
Engineered wood siding
Minnesota Roofing Company's 2026 LP SmartSide guide, showing a September update when retrieved September 30, 2026, publishes $8–$15 per square foot installed for Minnesota homeowners. Its planning range converts to $800–$1,500 per siding square, using the guide's definition of a square as 100 square feet of wall covering. The conversion is arithmetic from the same observation, not another price source.
Engineered wood fits when you want a wood-based manufactured cladding and can commit to its specified installation and finishing duties. Decide primed versus ExpertFinish before accepting a total. Have the bidder identify the profile, measured wall area, trim, flashing, and included installation scope, including who completes painting and seals field cuts.
The caveat is that the contractor range is local, not a national LP price list. It does not guarantee that removal, sheathing repairs, and finishing are included in every proposal. Also check replacement labor under the actual substrate and finish warranties: a long prorated product term can provide a different remedy after its initial period.
Cedar siding
Angi's cedar guide, updated July 9, 2026, gives $5–$11 per square foot overall, with installation-discussion categories of $5–$7 for clapboard, $6–$10 for board-and-batten, and $7–$11 for combined shakes/shingles. Homewyse's September 2026 wood-siding model starts at $10.99–$17.19 per square foot, but models primed wood boards generally rather than cedar specifically.
Cedar fits when the natural wood appearance matters enough to accept ongoing finish care and to choose a documented species, profile and grade. Specify the exposed face, course exposure, and measured wall area so the order can be traced to actual coverage. Identify who handles finish and cut-end treatment, including surfaces concealed after installation.
The caveat is category scope. Angi groups shakes with shingles and does not establish a price difference between them; Homewyse does not establish a cedar-only rate. Do not average these ranges into a new cedar estimate. Before ordering wood for a wildfire-prone address, also resolve local WUI applicability for the exact proposed wall covering and assembly.
Brick veneer siding
HomeGuide's brick-veneer guide, visibly dated June 16, 2025, gives $12–$18 per square foot installed for full-size face-brick veneer and $8–$18 with installation for thin brick. These remain historical U.S. estimates. Angi's July 8, 2026 guide gives $4–$22 per square foot to fully install brick siding, a broader category that does not isolate the two assemblies.
Brick veneer fits when you want a masonry finish and can specify the veneer assembly, backing, support and attachment for the existing structure. Mark whether the work covers the whole exterior or selected elevations. Have each bidder show drainage connections, flashing, and transitions at windows alongside its measured wall quantity.
The caveat is support. Full brick and thin brick carry their weight through different assemblies; a similar appearance does not make their retrofit work interchangeable. Ask what carries the veneer and what connects it to the existing wall. The dated ranges do not price an engineering review, a new ledge, or repairs automatically. Request those scope decisions before comparing complete alternatives.
