Roof replacement budget estimator

Enter measured roof surface area, including slopes. Your home’s floor area is a different measurement.

About $32,300 at 3,000 sq. ft.

JLC Cost vs. Value, 2025, South Atlantic region: standard 3,000 sq. ft. replacement.

Third-party planning figures, not a 3MG quote. Estimates multiply the published benchmark rate by roof area and round to the nearest $100. Pitch, tear-off, decking and structural work can change the price. Tile figures are statewide; specialty roofs and repairs require a separate assessment.

Questions worth asking.

How much does roof replacement cost?

Cost depends on measured roof area, roof shape, material, access and what needs replacing underneath. Use the estimator for planning, then request a written scope.

Can I switch from shingles to tile or metal?

It may be possible. The team should review structure, slope, roof details and applicable requirements before recommending a new material.

What happens if the decking is damaged?

Ask how decking is inspected and how any additional work will be documented, priced and approved before it proceeds.

How long will the replacement take?

Installation time depends on roof size, access, weather and what is uncovered during tear-off. Ask for a start window and an expected installation duration separately.

Do I need to leave home during installation?

Ask your project team about noise, driveway access, pets and any areas to keep clear while work is underway.

What should I compare between replacement quotes?

Compare the same measurements, material, flashing, ventilation, disposal, decking allowances and written warranty coverage.
