Budget estimate

$48,000 – $100,000

The maximum contract value is $484,000. Assuming a typical contractor net profit margin of 10‑20% for specialized roofing work, the expected earnings for the prime contractor would be roughly $48,000 to $97,000 after accounting for labor, materials, insurance, bond, and overhead costs. Factors influencing the range include the final material costs, any change orders, and efficiency of project execution.
