Many things change the final price. The size of your roof is a big one. A bigger roof needs more materials and more work. The shape of your roof also matters. A roof with many angles or steep slopes takes more time to replace. Removing your old roof adds to the cost too.
Getting a few quotes from local roofers is a smart step. This helps you compare prices and understand the job. Ask about the materials they plan to use. Asphalt shingles are a common choice.
Remember, the national range for asphalt shingle roofs is $3.50 to $6 per square foot, as of 2026, per This Old House. Your specific cost in Miami will depend on your home's unique needs. Always get detailed estimates.
