How Roof Replacement Costs are Calculated
A roof replacement is one of the most significant investments a homeowner can make. Our estimator uses current market data for materials and labor to give you a reliable budget range for your project.
Understanding "Roofing Squares"
In the roofing industry, materials are measured in "squares." One square is equal to 100 square feet of roof surface. While your home might be 1,500 square feet, your roof surface area is often 20-40% larger due to the pitch (slope) and overhangs.
Material Choice Impacts
The material you choose is the single biggest driver of cost. Asphalt shingles are the most common and affordable, while metal and tile offer superior longevity at a higher initial price point.
- Asphalt Shingles: Durable and cost-effective; lasts 20-30 years.
- Metal Roofing: High durability and energy efficient; lasts 40-70 years.
- Clay/Concrete Tile: Premium aesthetic and extremely long-lasting; lasts 50-100 years.
Labor and Local Factors
The complexity of your roof (number of valleys, steepness, and height) and local labor rates are factored into your estimate. Removing old layers of roofing and disposing of debris also contributes to the final labor cost.
Signs You Need a New Roof
Don't wait for a leak to start thinking about replacement. Look for curling or missing shingles, excessive granules in your gutters, or daylight peeking through the roof boards in your attic. Catching these signs early can prevent expensive structural damage from water infiltration.
