Budget estimate

$250,000 – $1,500,000

No contract value is disclosed. Based on the number of facilities (city hall, civic center, water‑treatment plant, multiple parks, and a sports complex) and the variety of roof types, a municipal roof‑replacement program of this scale typically ranges from several million to low‑double‑digit millions of dollars. Assuming an average of $150,000‑$300,000 per site for demolition, disposal, materials, and labor, and estimating 30‑50 sites, the total contract value likely falls between $5 million and $15 million. The contractor’s profit margin on such projects usually sits around 5‑10 %, so the expected earnings for the winning bidder would be roughly $250,000‑$1,500,000.
