Calculates total roof repair cost by evaluating damage type (missing shingles, flashing failure, leak point, sagging deck, or storm damage), affected area in square feet, roof material (asphalt, metal, tile, slate, flat membrane), roof pitch accessibility factor, and whether repair requires partial tear-off and re-layering versus surface patching — producing an itemized estimate covering materials, labor, debris removal, and permit fees where applicable.

Data Sources:

• RSMeans 2024 Residential Roof Repair and Maintenance Data
• HomeGuide roof repair cost surveys (60,000+ verified repair projects)
• National Roofing Contractors Association repair cost benchmarks
• Bureau of Labor Statistics roofing craft labor rates by metropolitan area

Key Assumptions:

• Roof decking beneath the repair area is structurally sound unless inspection reveals rot
