Understanding Roof Replacement Costs
Replacing a roof is one of the most significant investments a homeowner can make. The total cost is determined by several factors, primarily the "squares" (a roofing term for 100 square feet), material choice, and the physical complexity of the structure.
Key Factors in Your Estimate
Square Footage: Most roofers charge by the "square." Our calculator converts your total square footage into a comprehensive price estimate.
Material Choice: Asphalt shingles are the most affordable and common. However, materials like metal or slate offer longer lifespans but come with a much higher upfront cost.
Pitch and Complexity: A steep roof or one with many valleys, skylights, and chimneys requires more labor and safety equipment, increasing the final price.

Example Calculation
If you have a 2,000 sq. ft. roof with Architectural Shingles ($8/sq.ft. material cost) and Average Complexity (1.2 multiplier), the calculation works as follows:
(Area × Material Price) + (Area × Labor Rate × Complexity) = Total
