Corrugated sheet metal at Home Depot commonly costs about $20-$70 per panel, with an average near $35-$45 for a standard 8- to 12-foot galvanized steel panel. Price depends on panel length, gauge, coating, local availability, and whether the project also needs fasteners, trim, delivery, or installation.

| Installed metal roofing | $6 | $10 | $16 | Per sq ft; regional labor and tear-off affect total |
What Home Depot corrugated panels cost by length
For budgeting, a standard galvanized corrugated panel is often about $20-$45 for an 8-foot length and $35-$70 for a 12-foot length. Painted versions, heavier gauges, and specialty profiles can run roughly $25-$85 per panel. Store prices and stock are location-specific, so the product listing or local store quote is the best check before purchase.
Panel width is not the same as usable coverage. Overlaps between sheets reduce the area covered, and some profiles have a narrower effective width than their overall width. A common panel may be around 26-36 inches wide, while its coverage can be several inches less. Divide the roof or wall area by the panel’s stated coverage, then add material for overlaps, cuts, and waste.
A practical materials budget for a small 100-square-foot shed roof is often $250-$600 before labor. That estimate assumes basic steel panels, ordinary overlap, standard fasteners, and modest trim; unusual roof geometry or a premium finish can push the total higher.
Assumptions: U.S. retail pricing varies by store, panel profile, gauge, and inventory; figures are planning ranges, not guaranteed Home Depot quotes.
How panels, trim, and fasteners shape the receipt
The panel price is only one part of a complete roofing or siding purchase. A roof needs compatible fasteners and may need ridge caps, eave trim, gable trim, closure strips, and underlayment. Wall cladding can require corner trim and base flashing instead. Confirm that accessories match the panel profile and metal finish before buying.
| Quote item | Typical range | Pricing basis | What changes it |
|---|---|---|---|
| Corrugated steel panels | $20-$85 | Per panel | Length, gauge, coating, profile |
| Roofing screws with washers | $8-$30 | Per box | Count, screw length, finish |
| Ridge cap or flashing | $15-$45 | Per piece | Length, metal type, shape |
| Closure strips | $5-$20 | Per pack | Profile compatibility and pack size |
| Underlayment | $0.15-$0.60 | Per sq ft | Product grade and roll coverage |
| Delivery | $0-$150 | Per order | Distance, order size, service option |
For a modest roof, accessories may add $50-$200, while a larger or more detailed project can need several hundred dollars in trim, flashing, and underlayment. A missing ridge cap or incorrect screw can lead to another trip or water-entry problems. Check the package coverage and product specifications rather than estimating from the number of panels alone.
Fasteners, flashing, and delivery commonly add 15%-35% to a basic panel-only materials total. The share is usually higher on small projects because minimum quantities and delivery charges are spread over fewer panels.
Gauge, finish, and coverage change the panel price
Metal gauge is one of the clearest price drivers: a lower gauge number generally means thicker metal. Many retail corrugated panels are sold in lighter gauges, while heavier products may cost more and be stocked less consistently. Compare the listed gauge and product specifications, not just the panel price. Thicker material can be useful where durability or handling matters, but the structure still must support the roof assembly.
Coating affects both appearance and cost. Unpainted galvanized steel is often the budget choice. Painted or color-coated panels can add roughly $5-$20 per sheet, depending on length and finish. Specialty metals, including aluminum or copper, are not direct price equivalents to basic galvanized steel and can cost substantially more.
Panel length changes the price per piece, but not necessarily the cost per square foot. Longer sheets can reduce seams and installation time, yet they may require more careful transport and handling. Before comparing products, calculate the usable coverage and add overlap. A quote that looks cheaper per panel may cover less roof area.
Compare cost per covered square foot, not just cost per sheet. For example, a $40 panel covering 18 square feet costs about $2.22 per covered square foot before accessories, while a $32 panel covering 13 square feet costs about $2.46.
Example: $40 ÷ 18 sq ft = $2.22 per covered sq ft; confirm actual coverage on the selected product label.
Three project budgets for shed, porch, and garage roofs
A small shed roof can need 6-10 panels, depending on dimensions, panel coverage, and roof slope. At $20-$45 each for basic 8-foot sheets, panels may total $120-$450. Add $50-$150 for screws and simple trim, bringing the material estimate to about $170-$600. A complicated cut pattern or premium color adds cost.
A 200-square-foot porch roof might use 10-14 panels, with sheets priced around $25-$70 each depending on length and coating. Panels could total $250-$980, with roughly $100-$300 for fasteners, flashing, and closures. A basic materials budget could therefore land near $350-$1,280, excluding framing, underlayment, and labor.
A 600-square-foot detached garage roof can require about 30-40 sheets, depending on usable coverage and waste. At $30-$70 per panel, the panel portion may run $900-$2,800. Accessories and underlayment could add $300-$900. A realistic material range is about $1,200-$3,700, before tear-off or installation.
These examples are planning estimates, not bills of materials. Roof pitch, eaves, valleys, penetrations, and panel layout change sheet counts. A contractor should measure the actual roof and specify the panel system before materials are ordered.
Why roof pitch and 12-foot sheets affect the quote
Roof size is not simply the building’s footprint. A pitched roof has more surface area, and ridges, valleys, dormers, skylights, and chimneys create additional cuts and flashing work. A simple gable roof may need about 5%-10% extra material for overlaps and waste; complex layouts can need 10%-15% or more.
Long panels can reduce horizontal seams, but lengths above 10-12 feet can be harder to carry, lift, and cut safely. Transport may require a truck or special delivery, and some stores have limits on what they can load or deliver. If a panel must be cut on site, account for clean-cut tools and protection against sharp edges or coating damage.
Installation cost depends on labor and existing roof conditions. A straightforward installation over sound framing may cost around $4-$9 per square foot for labor, while a full installed project commonly falls around $6-$16 per square foot when materials and labor are combined. Tear-off, roof repairs, steep pitch, or difficult access can take the price above those ranges.
For illustration, a two-person crew working 10-16 hours at a combined billing rate of $100-$180 per crew-hour produces about $1,000-$2,880 in labor. Actual hours depend on roof area, safety setup, removal, and detail work; installer rates and minimum charges vary by market.
Roof complexity and removal can matter more than the retail price difference between two panel brands. Get labor, tear-off, disposal, and repair allowances listed separately so a low initial quote does not hide excluded work.
Regional delivery and installation rates across the U.S.
Retail panel prices can differ by store and supply, but labor usually creates the larger regional spread. In lower-cost rural markets, installed pricing may be about 10%-20% below a national metro benchmark. Large coastal cities and areas with high contractor demand can run 15%-35% higher, especially when access, parking, or building rules complicate delivery.
Climate and local building practices also affect the specification. Areas with heavy snow, high winds, or coastal exposure may require particular fastening patterns, underlayment, or corrosion-resistant materials. Those requirements can raise the material and labor budget even when the basic panel price is similar. Verify local code and manufacturer instructions before relying on a low-cost assembly.
Delivery can be free, discounted, or charged separately depending on the order and service. A small order may face a delivery fee around $50-$150, while a remote address or special handling can cost more. Long panels can be especially difficult to transport in a standard vehicle, and damage during transport can erase savings from picking up the order.
Use local quotes for installation and delivery rather than applying one national labor rate. Ask whether the contractor is collecting the panels, whether delivery is included, and who pays for damaged or incorrect sheets.
What installation, removal, and roof accessories add
For a new roof on prepared framing, installers may charge roughly $4-$9 per square foot for labor. Removal of existing roofing can add about $1-$4 per square foot, depending on material, layers, access, and disposal fees. Rotten decking is usually a separate repair, often priced by sheet or by the affected area after inspection.
Small jobs can have a minimum service charge of approximately $300-$800, even when the roof is only a few panels. Contractors must still schedule a crew, transport tools, and manage safety. A diagnostic or site visit may be free, credited toward the job, or charged separately; confirm this when requesting a quote.
Accessories are easy to underestimate. Ridge caps, drip edges, sidewall flashing, foam closures, and compatible screws must fit the selected profile. A simple roof may need $75-$250 in trim and fasteners, while multiple valleys, roof-wall intersections, or penetrations can increase those costs. Underlayment and ventilation components may also be required by the design or local rules.
Ask for a written scope that separates panels, accessories, tear-off, disposal, decking repairs, and labor. That format makes it easier to compare bids and identify whether a quote assumes existing sheathing is sound.
Corrugated steel versus plastic and standing-seam panels
Corrugated galvanized steel is often among the lower-cost durable roofing choices, but it is not the only option at a home-improvement store. Corrugated polycarbonate panels may cost around $25-$70 each, depending on length and light transmission. They are commonly used for covered patios or greenhouse applications, but should not be treated as a direct substitute for steel roofing unless the product is rated for the intended use.
Painted steel usually costs more than basic galvanized panels but offers color choices and can reduce the need for later painting. Standing-seam metal systems typically cost more because panels, clips, and installation require a different system. Installed standing-seam roofs can run roughly $10-$20 per square foot or more, depending on metal, roof geometry, and region.
For a small shed, asphalt shingles can have a lower material price, especially if the structure already supports them and no specialty trim is needed. However, shingles require an appropriate roof slope and underlayment. Compare total installed estimates, not just the price of sheets or bundles, and check expected maintenance and warranty terms.
Choose a substitute by intended use, roof pitch, and full installed price. A cheaper panel that is not approved for the application can create repair costs or fail to meet local requirements.
Cut the Home Depot materials bill without risking coverage
Measure the roof carefully and calculate panel coverage before ordering. A clear layout can reduce offcuts, but do not eliminate the allowance for overlap, damaged sheets, and cuts around edges. For a simple roof, keeping waste near 5%-10% may be possible; a roof with valleys or several penetrations may need more.
Compare the same specifications across products: panel length, usable width, gauge, finish, and accessory compatibility. A lower per-sheet price is not a saving if it requires extra sheets or does not match the trim already selected. Ask the store to confirm local inventory and delivery timing before arranging a crew.
Keep upgrades tied to the project’s actual requirements. A premium color or heavier panel may be unnecessary for a low-risk shed, while wind exposure or coastal conditions can justify a more robust specification. Avoid buying accessories by guesswork; use a measured takeoff and check the manufacturer’s installation details.
Combining materials into one delivery may lower transport expense, and scheduling outside a contractor’s busiest period can improve availability. If only a few sheets are damaged, replacing those panels may cost less than reroofing, provided the existing system is compatible and the repair restores proper flashing and fastening.
The safest savings come from accurate quantities and a complete, comparable quote—not from removing required flashing or fasteners. Keep receipts and product information, and confirm return rules before purchasing cut or special-order sheets.
