Homeowners typically pay more for aluminum roofing than for steel, with cost driven by material grade, panel size, installation complexity, and regional labor rates. The main price factors are material cost, coating options, and roof features such as pitch and drainage requirements.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Material Cost per Sq Ft | $4.50 | $7.50 | $12.00 | Aluminum generally higher than steel depending on alloy and coating |
| Installed Cost per Sq Ft | $6.50 | $9.50 | $14.50 | Includes removal, fasteners, insulation, and underlayment |
| Total Project (1,500 sq ft) | $9,750 | $14,250 | $21,750 | Assumes typical single-story roof |
| Labor Hours | 40 | 60 | 90 | Varies by pitch and complexity |
Assumptions: region, roof size, pitch, and crew availability.
Overview Of Costs
Starter note: Aluminum roofs command a premium upfront but offer long-term corrosion resistance and lighter weight, potentially reducing structural needs. Steel roofs are typically cheaper to install but may require protective coatings to extend life in corrosive climates.
Cost Breakdown
When evaluating price, consider four main components: Materials, Labor, Permits, and Miscellaneous. The numbers below show a typical mix for each metal type and a standard 1,500 square foot roof. The table includes totals and per-square-foot estimates to help compare value.
| Component | Aluminum — Low | Aluminum — Average | Steel — Low | Steel — Average | Notes |
|---|---|---|---|---|---|
| Materials | $4.50 | $7.50 | $3.50 | $5.50 | Coatings (PVDF or Kynar) add cost on aluminum |
| Labor | $4.00 | $5.50 | $2.50 | $3.50 | Pitch and complexity drive hours |
| Permits | $200 | $400 | $200 | $400 | |
| Delivery/Disposal | $150 | $300 | $150 | $300 | |
| Warranty | $100 | $200 | $100 | $200 | |
| Contingency | $150 | $300 | $100 | $250 | |
| Taxes | $0 | $0 | $0 | $0 | |
| Total (1,500 sq ft) | $9,450 | $14,250 | $6,000 | $16,700 | Assumes mid-range materials and standard crew |
Two niche drivers: aluminum coatings add 10–25 percent to material cost, and steel with advanced coatings may add 5–15 percent.
What Drives Price
Major cost factors include material selection, roof pitch, and coating quality. Aluminum often uses PVDF or silicone-modified coatings that protect against fading and corrosion, increasing cost. Steel relies on galvalized or stainless options, which vary by climate, with higher costs for premium rust inhibitors. Additional drivers are roof size, removal of old roofing, attic ventilation, and insulation upgrades. A steeper pitch or larger overhangs increases labor time and materials for flashing and underlayment.
Ways To Save
Smart budgeting steps can reduce up-front spending without compromising performance. Consider alternative profiles (standing-seam vs exposed-fastener) and limit premium coatings to critical areas. Purchasing off-season or during promotions may lower material costs. A lighter-substrate option can reduce structural reinforcement needs, and selecting a local installer with high-throughput work can reduce labor rates.
Regional Price Differences
Prices vary by region due to labor markets and material shipping. In the Northeast, expect higher installed costs due to labor rates and weather protection needs. The Midwest can be more affordable, while the West Coast often carries premium charges for coastal corrosion protection. Typical regional deltas are around: Northeast +8–14%, Midwest +2–8%, West Coast +10–16% compared with national averages.
Labor & Installation Time
Labor costs depend on crew size and roof complexity. A standard crew of three to four installers can take 2–4 days for a 1,500 sq ft roof, with pitch and attic access driving hours. On high-pitch roofs or multi-story homes, labor may exceed 6 days. Expect per-hour rates: aluminum installations typically $60–$90 per hour; steel installations $50–$80 per hour, depending on local wage scales.
Additional & Hidden Costs
Hidden charges can affect final price. Flange flashing, ridge caps, and snow guards are often sold separately. If old roofing contains asbestos or requires extensive removal, disposal fees and permits rise. Specialty fasteners, seam sealants, and warranty extensions can add 5–15 percent to the final bill. Some regions mandate permits with inspection fees that can range from $200 to $600.
