A standard 2,000 square foot single-family roof replacement in 2026 runs $7,000 to $17,000 installed for 30-year architectural asphalt shingles (average $10,250 per HomeGuide and This Old House 2026 data), $16,000 to $36,000 for standing-seam metal (Angi, Modernize 2026 reporting), $14,000 to $38,000 for concrete tile, $22,000 to $44,000 for clay tile, and $36,000 to $77,000 for natural slate. Those numbers include tear-off of one existing layer, synthetic underlayment, ice and water shield in valleys and eaves, drip edge, ridge cap, and a workmanship warranty on a simple gable roof in a mid-cost US market. Cut-up hip roofs, steep slopes over 8/12, multi-layer tear-offs, and rotted decking add 15 to 35 percent on top.
The calculator applies broad installed-rate tables to entered roof area, then adjusts the range by material, pitch band, story count, region, and optional tear-off. It displays a 40/60 material-and-labor allocation for planning; that split is not a supplier quote or crew estimate. Geometry, waste, accessories, decking repairs, disposal constraints, permits, and project-specific labor remain outside the model, so use the result as a comparison range rather than a line-item bid.
Use measured sloped roof area, not ground footprint. This calculator does not convert footprint and pitch into area; use a roof measurement or the separate roof-area calculator first.
Choose the covering represented by the broad installed-rate table. Product grade, manufacturer, fastening system, underlayment, flashing, and warranty can move an actual quote outside the displayed range.
The selected bands apply coarse multipliers to the installed range. They do not measure valleys, dormers, hips, access, staging, local wage rules, or job-specific production rates.
The toggle adds a broad regional tear-off range once. Layer count, material type, disposal, access, deck condition, and hazardous-material requirements still need a separate scope.
Take off waste, underlayment, flashings, ventilation, fasteners, accessories, decking repairs, permits, disposal, overhead, and margin as explicit lines. Reconcile the final bid against current supplier and subcontractor quotes.
A standard 2,000 SF architectural asphalt shingle roof replacement runs $7,000 to $17,000 installed in 2026 (average $10,250 per HomeGuide and This Old House data), or $5.09 to $6.66 per square foot on the national average. Standing seam metal runs $16,000 to $36,000 ($10 to $18/SF per Angi and Modernize 2026 data). Concrete tile runs $14,000 to $38,000. Clay tile runs $22,000 to $44,000. Natural slate runs $36,000 to $77,000+. Pitch, complexity, tear-off scope, and region drive 20 to 50 percent variance on top.
3-tab asphalt shingles are the cheapest residential roofing at $343 to $500 per square installed (materials $90 to $120/sq, labor $150 to $300/sq). Most contractors no longer install 3-tab on new replacements because 30-year architectural asphalt is only $100 to $300 more per square and lasts 50 to 100 percent longer with better warranty coverage. The cheapest practical replacement in 2026 is architectural asphalt from GAF, CertainTeed, or Owens Corning at $550 to $800 per square installed.
Standing seam metal is roughly 2x the installed cost of architectural asphalt: $1,000 to $1,800 per square installed vs $550 to $800 (per Angi and Modernize 2026 data). The premium pays back over the 40 to 70 year galvalume service life vs 15 to 25 for asphalt, plus avoided reroof cycles. Corrugated metal narrows the gap to $500 to $1,200 per square and is common on workshops, barns, and budget-conscious residential roofs. Class 4 impact-rated metal also qualifies for 5 to 35 percent homeowners insurance discounts in hail markets.
Industry pricing is per square — a roofing square equals 100 square feet of roof surface. A 2,000 SF roof is 20 squares. Asphalt shingles come in bundles: 3 bundles cover one square of architectural; 3 to 4 bundles cover one square of 3-tab and designer. When a homeowner quote shows $/SF, it is converted from the contractor-side $/square — same math, different denominator. Always confirm before comparing bids.
Single-layer asphalt tear-off runs $100 to $150 per square in 2026, plus $40 to $60 per square in disposal ($50 to $150 per ton landfill fee on 3 to 5 tons of debris per typical residential job, per SquareDash and HomeGuide). Multi-layer tear-offs (two or three layers, which require deck inspection and increase risk) run $150 to $250 per square. Tear-off is usually 8 to 15 percent of the total replacement cost.
This calculator is a planning range, not a bid-accuracy promise. It uses roof area, material, pitch band, stories, region, and optional tear-off, but it cannot see geometry, waste, accessories, access, deck condition, permits, supplier quotes, or crew production. Build those items explicitly and verify the scope on site before quoting.
Most US homeowners policies cover sudden damage from wind, hail, or fallen trees (Actual Cash Value or Replacement Cost Value depending on policy). They do not cover gradual wear or age-related failure. A storm-damaged roof files a claim where the carrier sends an adjuster, sets scope per Xactimate-aligned line items, and pays out minus the deductible (typically $1,000 to $5,000 for standard policies, higher in hail zones). Class 4 impact-resistant roofing (UL 2218 tested) qualifies for 5 to 35 percent premium discounts on the homeowner policy.
