Quality level
Roof replacement cost is driven mostly by two things: the square footage (and pitch) of your roof and the material you choose. Asphalt shingles are the budget default; metal, tile, and slate cost multiples more but last decades longer. This calculator estimates a full tear-off and replacement for a typical single-family home.
What drives roof replacement cost
- Roof size and pitch — steep, complex roofs with many valleys and dormers cost more to work on safely
- Material — asphalt shingle is the baseline; metal, clay tile, and slate multiply the price
- Tear-off and disposal of the old roof, plus any rotted decking that has to be replaced underneath
- Number of roof penetrations — chimneys, skylights, and vents each need new flashing
Roof Replacement cost — frequently asked questions
How much does it cost to replace an asphalt shingle roof?
For a typical home, an asphalt shingle tear-off and replacement usually falls in the lower-to-middle part of this range. Larger or steeper roofs and premium architectural shingles push it higher. Keep the quality on Budget or Mid-range for standard asphalt.
Is metal roofing worth the extra cost?
Metal costs roughly 2-3x asphalt up front but can last 40-70 years versus 15-25 for shingles, plus it's more energy-efficient and fire-resistant. Set quality to High-end to model a metal or tile roof. It's a strong long-term value if you're staying in the home.
Can I just add a layer over my old roof?
An overlay (roofing over existing shingles) is cheaper because it skips the tear-off, but most codes allow only two layers total, it hides deck damage, and it shortens the new roof's life. A full tear-off is what this calculator estimates and is generally the better long-term choice.
