Metal Siding Cost in 2026: Steel, Aluminum, Gauge, and Finish Warranties

Installed metal prices begin with the finish and wall area

Fixr's metal-siding guide, updated April 2, 2026, publishes $7–$16 per square foot installed for coated or painted steel, $4–$12 for its Galvalume steel category, and $3–$18 for aluminum. These are national budgeting categories. They do not establish a dealer price for Alside Satinwood, Satinwood Select, or Rollex aluminum.

The denominator matters: Fixr explicitly prices siding against exterior wall area, rather than interior floor area. Ask for the measured wall area, the treatment of openings, and the material allowance separately. A proposal described only by the size of the house leaves the amount of cladding unresolved. Request an elevation schedule showing which walls receive metal and which existing surfaces remain.

For the broader material decision, see siding materials compared. The vinyl siding cost guide investigates the lower-cost alternative and its own warranty conditions. Here, the useful metal comparison is between the supplied panel, its coating, and the remedy available if that particular product fails.

Steel and aluminum overlap with vinyl and fiber cement

The table keeps the current and historical estimates separate. The first column comes from Fixr's April 2026 installed-material tables. The second comes from HomeGuide's metal-siding article, whose visible body is dated August 1, 2023, despite its current search title. That older column is a historical reference, not a new 2026 survey.

Sources: Fixr's metal guide, material and comparison tables, and HomeGuide's installed comparison table. The steel overall category includes a different surface scope from the coated-steel row. Neither publisher provides matching bids for the same house in every material.

The ranges overlap enough that the material name cannot determine the cheapest complete proposal. Ask each bidder to price the same elevations, removal work, wall repairs, trim, finish, and access. An aluminum proposal can include more work than a steel proposal; a premium vinyl proposal can include different accessories from a basic metal one. Read the actual scope before assigning the difference to the panel alone.

Do not subtract the lowest endpoint of one category from the highest endpoint of another to calculate a saving. The endpoints represent different purchases. Likewise, a published per-square-foot range does not tell you whether a particular company includes disposal or surrounding finish repair. Ask it to identify those items beside its total.

Why the aluminum estimates disagree

Fixr's February 13, 2026 aluminum guide gives $3–$10 per square foot in its installation discussion. Its later general metal guide expands aluminum to $3–$18. The documents therefore disagree on the upper end even within the same publisher. Keep both scopes and dates attached; averaging them would create a figure neither document publishes.

Neither document provides a matched project sample establishing why the upper endpoints differ. Use the narrower guide as one budget reference and retain the wider published range alongside it. Ask a company whose quote falls outside either range to explain the actual ordered product and work.

The same caution applies when comparing a published category with an advertised product price. A panel supplied without installation is a different purchase. Have the installer identify the exact panel, all required accessories, and the labor included. Record whether removal, disposal, permits, access equipment, and concealed wall repairs are fixed, excluded, or separately authorized.

You can then compare the proposals without manufacturing a national average. If one bidder changes the profile or finish to lower the price, request a revised specification beside the revised total. Keep the original and alternative descriptions together so that the apparent saving does not conceal a different installation or warranty.

Named products: coating and warranty differences

The Alside April 2026 catalog, printed pages 56–57, distinguishes Kynar-coated Satinwood Select from PVC-coated Satinwood. The Rollex 2025 product guide, C11, identifies smooth J-8HS019 and woodgrain J-8HT aluminum siding. Those catalog names need to appear in the order, rather than disappear into the word “metal.”

Sources: Alside catalog, Alside steel warranty, Satinwood Select warranty, Rollex product guide, and Rollex aluminum warranty. The judgment row translates differences into order questions; it does not rank brands or estimate their prices.

Gauge belongs to the exact manufactured item

Alside's catalog, printed page 63, lists the gauge figures above for seamless steel coil used to form identified profiles. It is a different entry from the factory-panel listings. Request the panel specification for what the installer will actually supply, including whether it is factory formed or formed from coil.

Rollex's 0.019 inch figure belongs to the aluminum siding entries in C11 of its product guide. The guide also contains soffit, fascia, and trim-coil dimensions. Those neighboring specifications should not become the siding thickness simply because they appear in the same catalog. Keep the stock code attached to the figure.

A useful order names the metal, profile, thickness specification, finish, color, and accessory system. Ask the bidder to show the manufacturer's document row for each substitution. If a seller supplies only a steel gauge for one option and an inch thickness for the other, ask for clarification rather than inventing a conversion or a performance score.

Thickness information also does not establish the outcome of a hail test. Request a report for the selected product if the seller makes a tested-impact claim. Keep that report distinct from the warranty remedy. A construction specification explains what is supplied; a test explains a particular evaluated condition; a warranty explains responsibility under its stated rules.

Finish protection permits defined change

The Alside steel warranty limits its chalk and color-change protection to 15 years. Its coverage uses measured thresholds after foreign deposits are removed. Ask which complaint process applies to fading, chalking, peeling, and substrate damage; the same visible symptom does not necessarily fall under the same clause.

For Select, the separate PDF extends the color-change period to 35 years, with a Delta E threshold of 5 Hunter Units. Its hail remedy remains conditional and material-only. A longer finish period therefore does not turn storm repair into a complete installed replacement.

Rollex's aluminum warranty provides 25 years of defined chalk and color protection and excludes nonuniform changes from unequal sunlight exposure. It also declines to guarantee an exact color match when only defective portions are replaced. Ask how the supplier handles a partial repair on a highly visible elevation.

The purchase implication is to separate your appearance preference from the remedy promised. Inspect physical samples and request the exact color code, then retain it with the invoice. Ask who evaluates a later finish complaint and whether a replacement may differ from neighboring panels. Do not assign an assumed repainting allowance or an unchanged-color lifespan from the headline term.

Hail coverage leaves different costs with the homeowner

The Alside steel PDF, Remedies section, requires the homeowner to pursue insurance first; its hail remedy becomes available if coverage is denied. Both Alside PDFs limit hail protection to the continental United States. The authorized remedy supplies replacement material, while the owner remains responsible for labor and other replacement costs. The document specifies a $200 payment per incident and building or structure.

Ask the seller to explain the claim sequence before describing the product as covered for hail. Identify who documents the damage, who contacts the manufacturer, and whether work must await authorization. Request the applicable document with the proposal. A verbal promise that “hail is covered” leaves the central installation-cost question unanswered.

The Rollex aluminum PDF expressly excludes hail storm damage. Its defect remedy and long finish term do not reverse that exclusion. If the installer offers separate damage coverage, ask for that agreement and its responsible party instead of attributing it to Rollex.

Consider the cost of reaching and repairing the damaged area when comparing proposals. Ask for the repair method, likely extent of panel removal, availability of matching material, and any separate workmanship promise. These are matters for a project-specific response, rather than a made-up national storm-repair price or an assumption that the entire elevation will be replaced.

Great Plains hail exposure is a reason to inspect the remedy

A 2023 hail-climatology paper by Battaglioli and colleagues, hosted by NOAA, PDF page 13, identifies spring concentrations of modeled large and very large hail in the southern Great Plains, including Texas and Oklahoma. It describes modeled summer hail activity shifting north, with a maximum across western Nebraska and South Dakota. This is regional climatology, not a prediction that a particular house will be hit.

For a project in those named regions, bring the hail clause into the initial material conversation. Ask the company to show the ordered product's test evidence where claimed, the manufacturer's damage remedy, and its own workmanship terms. Ask your insurer separately about the property's policy. The regional finding gives a reason to ask; it supplies neither an insurance discount nor a local installed price.

Do not treat a long warranty term as evidence that a panel cannot dent. Also avoid assuming that a product without a hail warranty is unsuitable for every home. The relevant comparison is the homeowner's chosen appearance, documented exposure evidence, and accepted repair responsibility. Have the bid state which promised protections actually accompany the order.

Coastal corrosion exclusions survive the metal label

Alside's steel warranty limitations distinguish manufacturing defects causing substrate deterioration from damage due to listed environmental causes, including salt spray. Rollex's aluminum limitations likewise exclude salt spray in the atmosphere and direct contact or runoff from specified dissimilar materials.

For an Atlantic, Gulf, or Pacific coastal property, request written confirmation that the selected product and accessory system suit the address. Ask the installer to identify the corrosion exclusions and show how adjacent flashing, gutters, masonry, and treated materials will be handled. The cited exclusions establish a warranty boundary; they do not prove that every coastal installation will fail.

A useful drawing identifies interfaces as well as the broad field of siding. Ask where different metals meet, where runoff crosses a panel, and which details are prescribed by the manufacturer. Have the bidder resolve those details before promising general corrosion resistance. Ask it to identify the approved care instructions and the contact for a coating problem.

Avoid replacing those questions with a salt-fog number borrowed from an unrelated component sheet. A laboratory result for one coating or accessory would need its product scope stated. For a coastal purchase, the decisive evidence is applicability to the ordered siding and its actual installation, together with the complete exclusions in the governing warranty.

Removal, repairs, and trim need their own scope

HomeGuide's historical guide treats old-siding removal as an extra, giving $0.70–$2.00 per square foot in its 2023 estimate. Keep that date visible if you use the figure. Ask current bidders whether their complete installed totals already include removal and disposal before adding any allowance.

Request an explanation of what happens after the old siding comes off. Have the company distinguish included preparation from repairs requiring separate authorization. Ask it to record findings with photographs and obtain your agreement on repair scope. An open-ended reference to “necessary repairs” is difficult to compare against a proposal that identifies the excluded work.

Treat trim, soffit, fascia, and gutters as specified products. They may be quoted alongside siding, but the panel warranty does not by itself describe every accessory. Ask which pieces are replaced, which are retained, and which finish and warranty apply. Have the company explain any reuse that affects the appearance or the installation detail.

At openings and transitions, request a written description of the flashing and surrounding finish work. Keep that scope attached to the siding total so that another bidder can price an equivalent purchase. Ask who restores disturbed fixtures, landscaping, and adjacent surfaces. These questions make the proposal reviewable without inventing an allowance for every possible complication.

A manufacturing-defect remedy has its own timeline

The Alside steel warranty, Remedies section, treats a manufacturing-defect claim differently from hail. Within the first three years from installation, Alside chooses repair, refinishing, or replacement at no cost to the owner. After that initial period, the document specifies a $100 payment per incident and building or structure for warranted material and labor work. This is a homeowner service charge, not an installation estimate.

Ask a bidder discussing lifetime coverage to identify that distinction. A manufacturing problem and a storm-damaged panel should have separately described claim paths. Request the manufacturer document, the installation date used for coverage, and the evidence the company expects with a claim. Keep any additional dealer service agreement separate so that the responsible party remains clear.

For transferred Alside coverage, the PDF's schedule reduces the manufacturer's share from 100% in years 1–5 to 10% from year 14 through the applicable term. Its schedule defines basic-coverage costs as material and labor, while hail costs mean material only. The percentage therefore cannot be understood without the covered-cost definition. Ask the seller to explain the schedule for the ownership category that applies to the property.

This changes how a subsequent homeowner should read the long term. The remaining years identify the period during which a qualifying claim can be considered; they do not promise that all future repair expenses are paid. Preserve the original installation paperwork when the house changes hands and ask the manufacturer about transfer requirements. Avoid treating the remaining term as a cash value to add to the house.

Partial replacement and authorization affect a repair

The Rollex warranty allows replacement of only defective portions and substitution when the original product is unavailable. Its remedy does not commit to renewing every unaffected panel on an elevation. Ask how the supplier will assess an appearance difference between new material and the surrounding installation before expecting a complete wall replacement.

The Alside steel warranty likewise reserves substitution rights if the original siding is unavailable. Ask which stock codes and colors are being supplied and keep photographs of carton labels. If a bidder offers spare panels, request the amount and storage instructions in its proposal. Spare material can be useful to discuss without claiming that it guarantees a future exact match.

Both documents require a manufacturer opportunity to respond before corrective work is undertaken. Rollex's PDF specifies written permission before homeowner-arranged corrective work. Ask the installer to explain when a concern should be reported to it and when it must go to the manufacturer. Keep claim correspondence and photographs together; do not commission a repair on the assumption that any expense will later be reimbursed.

At proposal stage, request a description of service access and responsibility for disturbed adjacent work. An accepted panel-defect claim still needs a defined repair plan. Have the supplier identify which work follows the manufacturer's remedy and which work requires another agreement. That makes the later service discussion as concrete as the original installation comparison.

Ownership, maintenance, and later repairs

The Alside steel warranty separates original-owner coverage from prorated coverage upon transfer. Rollex's aluminum warranty also changes the cost-sharing arrangement for subsequent owners. Ask which ownership category applies when buying for a rental, entity-owned property, or recently purchased home.

Request the registration and transfer instructions with the completed order. Keep the installation date, invoice, stock codes, color, and warranty together. Ask the installer to identify the manufacturer claim contact and its own workmanship contact. A future buyer should receive the actual documents rather than an unsupported description of transferable lifetime coverage.

Rollex's registration wording deserves a careful read: it first describes validity after registration, then expressly says failure to register within the stated period will not void the warranty. Registration helps establish the purchase date. Ask the supplier to complete the paperwork and retain your own proof rather than summarizing the first sentence as an automatic forfeiture. If registration or transfer has been missed, contact the manufacturer about the actual record and applicable requirements. That preserves the distinction between documenting the purchase and deciding whether a particular claim is covered.

For cleaning, follow the supplied product instructions. The Alside PDF cautions against abrasive or solvent cleaners; the Rollex PDF includes cleaning and surface-alteration conditions. Ask for approved treatment of a scratch or stain instead of assuming any metal paint or cleaner preserves coverage.

Before accepting the work, inspect the delivered and installed surfaces with the company. Record damage, substitutions, and unfinished details, and request a response against the signed specification. Retain approved spare material if offered and ask how it should be stored. The completed purchase should leave you with an identifiable product, a defined installation, and a documented path for service.

What we could not verify

• Mastic's 2020 specification-guide PDF returned HTTP 403 on plain fetch, HTTP 404 with a browser user agent, and an internal error on web open. A same-site search did not recover that 2020 document. Mastic gauge and warranty claims are omitted; the comparison uses fetched Alside and Rollex documents.

Questions to ask before you compare quotes

• What measured wall area and installation work does the total cover?
• Which panel, gauge or thickness, and finish are being supplied?
• Does the hail remedy pay installation labor?
• Which salt-spray and dissimilar-material exclusions apply at this address?
