surface = 2,000 × 1.118 = 2,236 sq ft
Modernize: 2,236 × $6 to $9 = $13,420 to $20,120 + tear-off $4,470 to $11,180
RoofingCalc: 2,236 × $4.50 to $6.50 = $10,060 to $14,530 + tear-off $1,120 to $13,420

Installed prices per square foot, as each guide publishes them, times your roof surface. The permit is added to the total above.
These are national published ranges, and they’re wide. Get two or three local quotes, and compare them per square.
Every guide says a steep pitch or a second storey pushes the price toward the top of its range; none gives a number for it.
Rotten roof decking found during the tear-off is extra. Ask each roofer for their price per sheet before the job starts.
How we work it out
Roofers price by the square, 100 sq ft of roof surface. The surface is the footprint from above times the pitch factor, so a steeper roof costs more for the same house. We multiply your surface by each guide's installed price per square foot and add its tear-off price.
cost = footprint × √(1 + (pitch ÷ 12)²) × installed price per sq ft
We only use figures each guide gives as installed, materials and labor together, and we checked each one on the guide's own page. Fixr's architectural shingle price isn't called installed, so it's left out. Modernize gives clay the same range as concrete, which we show as it is.
No guide we could read prices a tile lift and relay, where the tiles come off and go back on new underlayment. For that we add up the parts Fixr does price, removal and new underlayment with labor, and leave the relaying to your quotes.
