On insurance work, an accurate supplement is often the difference between a break-even roof and a profitable one — this shows the swing.
The math, in plain terms.
Revenue is squares times your price per square, plus any supplement recovered on insurance work. A square is 100 square feet of roof; pricing and costs are easiest to reason about per square.
Costs are material and labor per square times the number of squares, plus an overhead allocation as a percentage of revenue. Gross profit is revenue minus all three; margin expresses it as a percentage.
Profit per square is the fast field metric — it tells you whether a job is worth the crew-day and how much a supplement adds. Recovering a legitimate supplement flows almost entirely to gross profit because the material and labor were already accounted for.
Questions, answered.
What is a roofing supplement?
A supplement is additional scope submitted to an insurer for work an initial estimate missed — code-required items, extra layers, or damage found on inspection. It documents observed conditions; it does not predict what a carrier will approve.
How do I calculate profit per square?
Divide total gross profit by the number of squares. It's a quick way to compare jobs and to see the profit impact of an approved supplement.
Is this a guarantee of profit or carrier approval?
No. It's a planning estimate. It excludes taxes, callbacks, and financing, and it never predicts insurer decisions. Verify supplement scope with your state DOI and licensing board.
