# Metal Roof Cost Calculator

> Metal roof cost estimator: enter footprint, pitch, panel type and tear-off to get roof area, squares and installed cost. Rates are yours to set, not our guesses.

## Key facts

- Roof pitch changes what you pay for: the same 2,000 sq ft footprint is 2,062 sq ft of roof at 3:12 and 2,828 sq ft at 12:12, a 37% difference in area before anyone talks about price.
- A roofing square is 100 square feet, so a 2,000 sq ft footprint at a 6:12 pitch is 22.4 squares, not 20.
- Roofing is not on the IRS list of property qualifying for the energy efficient home improvement credit, and that credit only applies to qualifying property placed in service before December 31, 2025, so there is no federal metal roof tax credit for a 2026 installation.

## Data

- Roof pitch to real roof area, squares and installed cost. Methodology: Roof area = footprint x slope multiplier, where the multiplier is the square root of 1 plus (rise/run) squared. That part is geometry and is exact. Squares = roof area / 100, the unit US roofers quote in. Order area adds a 10% waste allowance. The cost column multiplies roof area by $15.50 per square foot, the calculator's default of $14 standing seam installed plus $1.50 tear-off; those two rates are typical 2026 US quote figures, not sourced from any official publication, and both are user inputs on the calculator so you can substitute your own. Every row here is computed with the same expressions the calculator runs.
