PermaLock aluminum shingles typically cost about $14-$24 per square foot installed, with roof size, tear-off, roof shape, and local labor rates driving the quote. For a 2,000-square-foot roof, that usually means roughly $28,000-$48,000 before unusual repairs or complex details.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Installed PermaLock roof | $28,000 | $38,000 | $48,000 | 2,000 sq ft of roof surface |
| Installed price per sq ft | $14 | $19 | $24 | Standard to complex roof scopes |
| Material allowance | $7 per sq ft | $10 per sq ft | $13 per sq ft | Shingles and typical system components |
| Removal and disposal | $1 per sq ft | $2 per sq ft | $4 per sq ft | Varies with layers and access |
Assumptions: U.S. pricing, a 2,000-square-foot roof surface, standard colors, sound decking, and ordinary access; confirm current product availability and local installer pricing.
What a 2,000-Square-Foot PermaLock Roof Usually Costs
Installed pricing commonly falls around $14-$24 per square foot, or $1,400-$2,400 per roofing square; one roofing square covers 100 square feet. A straightforward roof with open access may land near the lower end, while steep slopes, many valleys, and premium trim can push a quote upward.
A reasonable planning budget is about $38,000 for 2,000 square feet, with a practical range of $28,000-$48,000. The estimate assumes installation over a typical residential roof, not necessarily the home’s floor area. Roof surface measurements can exceed the house footprint because of pitch and overhangs.
How Shingles, Labor, and Tear-Off Shape the Quote
Quotes combine the metal roofing package with installation labor and job-specific work. Ask whether the price includes underlayment, flashing, starter and ridge components, fasteners, and cleanup; product and installation scopes can differ between contractors.
| Quote component | Typical range | Pricing basis | What changes it |
|---|---|---|---|
| Shingles and system materials | $7-$13 per sq ft | $14,000-$26,000 for 2,000 sq ft | Finish, components, supplier quote |
| Installation labor | $4-$8 per sq ft | $8,000-$16,000 for 2,000 sq ft | Pitch, details, crew rates |
| Underlayment and flashing | $1-$3 per sq ft | $2,000-$6,000 for 2,000 sq ft | Roof condition and code needs |
| Removal and disposal | $1-$4 per sq ft | $2,000-$8,000 for 2,000 sq ft | Existing layers and dump fees |
| Permits and site protection | $300-$1,500 | Per project | Local rules and site logistics |
Labor and materials overlap in some installed quotes, so the component ranges are budgeting aids, not amounts to add automatically. Compare written bids by matching included work and product specifications.
Roof Pitch, Valleys, and Panel Details That Raise Price
Roof geometry is a major cost driver. A simple gable roof with a pitch below 6:12 may need fewer cuts and safety measures; a roof above 8:12 can require slower handling and additional fall protection. Multiple dormers, valleys, hips, and skylights add trim work and installation time.
Scope also changes with roof area and deck condition. A roof over 2,500 square feet may have a lower per-square-foot rate than a small, intricate 1,000-square-foot roof, but its total remains higher. Replacing damaged decking can add roughly $3-$8 per square foot of affected area, depending on material and access.
Get the quote based on measured roof surface, pitch, and a written count of penetrations and trim details. An estimate based only on house size can miss meaningful labor and material differences.
Installation Hours and Crew Costs for Aluminum Shingles
A typical 2,000-square-foot roof may take a crew of three or four about 4-8 working days, depending on tear-off, weather, pitch, and detailing. Labor pricing varies widely by market; residential roofing crews may be billed at an effective $50-$100 per worker-hour, though contractors commonly quote the complete project rather than hourly work.
Longer installation time is most likely when the roof has steep sections, many transitions, or repairs discovered after removal. Confirm the expected start date, working-day estimate, weather plan, and whether temporary protection is included if the roof is opened in stages.
Removal, Deck Repairs, and Other Costs Outside the Shingle Price
Removing one layer of asphalt shingles and hauling it away often adds $1-$4 per square foot. Multiple layers, difficult driveway access, or heavy local disposal fees can raise that charge. Old metal removal may be priced differently, so the estimate should identify the existing roof type and number of layers.
Deck repairs, new flashing, gutter changes, and chimney or skylight work are often separate. Set aside a contingency of about 5%-10% for uncertain repairs, but ask the installer to seek approval before exceeding the agreed allowance.
Separate confirmed work from allowances so unexpected expenses do not disappear inside a vague lump sum. A clear proposal should list disposal, decking rates, flashing, and any permit charges.
Regional Labor Rates Can Shift a PermaLock Installation
For comparable roof size and scope, labor-heavy markets in the Northeast, West Coast, and major metro areas can run about 10%-25% above national planning figures. Rural markets and parts of the South or Midwest may come in about 5%-15% below them, although installer availability and travel distance can reverse that pattern.
Use local written bids rather than applying a national average as a guaranteed price. Ask whether the installer regularly handles interlocking aluminum shingles; familiarity with the specific system can affect both labor assumptions and warranty terms.
Three PermaLock Roof Quotes for Different House Shapes
A 1,500-square-foot simple roof at $15 per square foot would total about $22,500, with roughly 100 labor hours at an assumed $60 per hour included in the installed rate. A 2,000-square-foot moderate roof at $19 per square foot would be about $38,000, with approximately 150 labor hours. A steep, detailed 2,400-square-foot roof at $24 per square foot would reach $57,600, with around 220 labor hours.
These examples illustrate scope-based budgeting, not manufacturer-set prices or guaranteed bids. Actual estimates depend on measured roof area, local wage rates, product terms, removal, and repairs.
Ways to Lower the Aluminum Shingle Quote Without Cutting Corners
Keep the scope consistent while comparing at least three itemized bids. Choose a standard finish if available at a lower price, avoid upgrades that do not serve a clear need, and schedule before urgent leaks force rush work. Combining roof work with planned flashing or skylight repairs may reduce repeat mobilization charges.
Homeowners can reduce uncertainty by clearing driveway access and discussing existing roof layers before the crew arrives. They should not skip underlayment, flashing, or required safety and code work to lower a bid.
The most useful savings usually come from simpler scope, planned timing, and comparable quotes—not from omitting essential installation details. Verify that each proposal specifies the PermaLock system, installation method, cleanup, and applicable workmanship and product warranties.
