How Much Does a New Roof Cost?

Roof replacement cost depends mainly on three things: the size of your roof, the material you choose, and how complex the roof shape is to work with. Asphalt shingles remain the most affordable option for most homeowners, while metal, tile, and slate cost more upfront but typically last two to three times longer. A steep or multi-angled roof takes longer to install safely and requires more scaffolding and material waste, which is why complexity adds meaningfully to the final price. This calculator gives a national-average estimate — always get two or three quotes from local, licensed roofers before budgeting, since labor costs vary significantly by region.

Tips

Asphalt shingles are cheapest upfront; metal and tile cost more but last longer.

Ask about warranty length — it varies a lot between contractors.
