How Does a Roof Replacement Cost Calculator Work?
A roof cost calculator estimates total expenses by factoring in your roof’s square footage, material type, labor, and extras like removal or permits. Start by measuring your roof (not house) area—add 10-20% for pitch and overhangs. Multiply by $4-$11 per square foot for asphalt shingles, the most common choice. Online estimators provide quick ballparks, but for precision, consult local pros.
Pro tip: In high-wind areas like Florida, add 10-20% for impact-resistant materials.
