How Much Does a Roof Replacement Cost? Full 2026 Data

What Goes Into a Roof Replacement Quote?

A roof replacement estimate covers four cost buckets: tear-off and disposal, underlayment and decking repairs, new roofing material, and labor. The material line item is the most variable — architectural shingles cost roughly $4.50–$6.50 per square foot installed, while standing seam metal runs $14–$22 per square foot for the same coverage area. That spread is why two identical-sized homes can receive estimates that differ by $20,000.

Contractors price in roofing squares, where one square equals 100 square feet of roof surface. A 2,000-square-foot home with a moderate-pitch hip roof has approximately 22–26 roofing squares. Every line in your estimate — materials, underlayment, ice-and-water shield, ventilation upgrades, disposal — is priced per square, so understanding your square count is the first step to evaluating any bid.

Roof Replacement Costs by Material Type

Material choice is the single largest cost driver in a roof replacement. The table below reflects installed costs — materials plus labor — per square foot for a typical residential roof in 2026.

• 3-tab asphalt shingles: $4.00–$5.50/sq ft — 20-year warranty, adequate for mild climates
• Architectural (dimensional) shingles: $4.50–$7.00/sq ft — 30-year warranty, standard for most homes
• Impact-resistant shingles: $5.50–$8.50/sq ft — Class 4 rated, may qualify for insurance discounts
• Standing seam metal: $14–$22/sq ft — 40–70 year lifespan, excellent in snow and high-wind zones
• Metal shingles or panels: $9–$16/sq ft — metal durability with shingle appearance
• Concrete tile: $10–$18/sq ft — 50+ year lifespan, common in Southwest and Florida
• Clay tile: $15–$30/sq ft — 75–100 year lifespan, requires structural support assessment
• TPO/EPDM flat membrane: $6–$12/sq ft — commercial and low-slope applications

How Home Size Affects Total Cost

The relationship between home footprint and roof area is not 1-to-1. Roof area depends on pitch, the number of planes, dormers, hips, and valleys. A 1,500-square-foot ranch home with a simple gable roof might have 18 roofing squares. A 1,500-square-foot home with a complex hip roof and multiple dormers could have 26 squares — 44% more roofing surface and proportionally more cost.

Regional labor rates add another dimension. Labor in coastal metros like San Francisco, Boston, and Seattle runs 30–45% higher than national averages. Labor in the Southeast and Midwest is typically 10–20% below the national average. When comparing estimates across contractors, always verify whether the quote includes ice-and-water shield (required in cold climates), upgraded ventilation, and permit fees — these add-ons significantly affect final cost.

What a Replacement Quote Should Include

A complete roof replacement quote should itemize: tear-off and disposal of old roofing, decking inspection and repair allowance, starter strip, underlayment (and ice-and-water shield in applicable climate zones), new field material, ridge cap, all flashing (pipe boots, step flashing, valley metal), ventilation components, and a cleanup and haul-away line. Any quote that lists only materials and a total labor number without these line items is incomplete.

Warranty terms are equally important to price. Manufacturer warranties on architectural shingles typically run 30 years on the material, with a separate workmanship warranty from the contractor covering installation defects for 1–10 years depending on contractor certification level. GAF Master Elite and CertainTeed SELECT ShingleMaster contractors can offer enhanced system warranties that cover both material and labor. Always ask for the warranty certificate in writing at job completion.
