Understanding Your Roof Replacement Estimate
Replacing a roof is one of the most significant investments a homeowner will make. The total cost is determined by several factors beyond just the size of your home. Use our calculator to get a realistic ballpark figure based on current 2024 market averages.
Key Factors That Influence Cost
Square Footage: Roofing is measured in "squares," where one square equals 100 square feet. The more surface area, the more materials and labor required.
Material Choice: Asphalt shingles are the most budget-friendly, while premium materials like slate or clay tile can quadruple the price due to material cost and specialized labor.
Pitch and Slope: Steeper roofs are more dangerous and difficult to work on, requiring specialized safety equipment and more man-hours.
Complexity: Chimneys, skylights, dormers, and multiple roof lines increase the time spent on flashing and cutting shingles, which raises the labor cost.
Example Cost Breakdown
A standard 2,000 sq. ft. roof with architectural shingles and a standard pitch typically costs between $12,000 and $18,000. However, if you choose premium metal or tile, that same roof could cost upwards of $35,000.
When Should You Replace Your Roof?
Most asphalt roofs last 20-25 years. Look for signs like curling shingles, bald spots (loss of granules), or daylight visible in the attic. If your roof is nearing the end of its lifespan, it is better to replace it before active leaks cause structural damage to your home.
