Is this roof quote actually paying you? Free, no signup.
Profit per square after materials, labor, and overhead. A 20-sq house at $100/sq profit is $2,000 in your pocket.
Shingle $/sq should include your waste factor. Architectural shingles often land $150-200/sq with waste baked in.
Labor $/sq is what the crew costs you per square installed, before the pitch adder.
Jobs like this one to hit your take-home goal.
Roof quotes die on flat per-square pricing. A $400 per square number looks fine until the tear-off layers, the steep pitch, and the valleys quietly eat it, so this calculator builds the quote from every cost line. Start with your bar: the minimum profit per square you want to clear (100), plus a monthly take-home goal. Pick a preset: Ranch (22 squares, 1 tear-off layer), 2-story (24 squares, 15 percent pitch adder), or Steep (26 squares, 2 layers, 35 percent adder), all editable starting points. The leaks card holds the steep-pitch percent adder on labor, valleys and dormers by the count, flashing and vents flat, dumpster and dump fees, crew labor per square, and travel plus permits. Results show a line-item breakdown, true cost per square as the big number, and the recommended quote, which adds your per-square profit and rounds up to the nearest $100 so the bid lands clean. The quote check grades your instinct total with LOSING MONEY, WORKING TOO CHEAP, or PRICED FAIRLY verdicts and the exact dollars left on the table. The month planner turns the goal into roofs. No signup; runs on your phone.
Example only, not typical pricing. 2-story preset at a $100 per square profit bar: 24 squares. Materials = 175 shingle + 40 underlay + 1 x 50 tear-off = $265 per square. Labor with the 15 percent pitch adder = 125 x 1.15 = $143.75 per square. Extras = 4 valleys x 150 + 600 flashing + 500 dumpster + 200 travel = $1,900. True cost = 24 x (265 + 143.75) + 1,900 = $11,710, or $487.92 per square. The recommended quote adds 100 x 24 = $2,400 of profit: 11,710 + 2,400 = $14,110, rounded up to the nearest $100 = $14,200 ($591.67 per square). A $12,000 gut quote keeps 290 of profit, which is $12.08 per square, so the verdict is WORKING TOO CHEAP with $2,110 left on the table. A $10,000 gut quote is $1,710 short of true cost, so LOSING MONEY. A $10,000 month goal needs 10,000 / 2,400 = 4.17, rounded up to 5 roofs.
**Q** Why is the bar per square instead of per hour?
Because roofers bid and think in squares. Your bar is profit per square after materials, labor, and overhead, and a 24-square house at a $100 bar is $2,400 in your pocket. The tool does the hourly math for you through the labor line.
**Q** How do tear-off layers change the quote?
Enter the layer count and your tear-off cost per square per layer. Two layers at $50 is $100 per square of real work before a shingle goes on. The breakdown shows it as its own line so skipping it is impossible.
**Q** What does the pitch adder do?
It raises crew labor by your percent for steep work. A 15 percent adder turns $125 per square of labor into $143.75, and the labor line renders in amber so the pitch cost is visible in the total.
**Q** Why round the quote to the nearest $100?
Because a bid of $14,200 reads cleaner than $14,110 and the rounding is always up, in your favor. The exact need-quote number still shows in the breakdown for your records.
**Q** What does the month planner assume?
That every roof this month looks like this one. Five 2-story roofs to hit a $10,000 goal is a different month than five steep ranches. Run each job type separately for honest numbers. ---
