Project location

Used to match your project with professionals in your area. Estimates use US baseline pricing and are not adjusted by ZIP code.

Roof size and shape
Which measurement do you have?

The ground-floor area under the roof, including an attached garage and covered porches. For a two-story home, count one floor only.

Roof pitch

Pitch is the rise in inches for every 12 inches of run. Most homes are moderate. A steep roof is one you could not comfortably walk on.

Metal roofing and existing roof

Metal can often be installed over a single layer of asphalt shingles where local code allows. The deck is the plywood or board layer under the roofing.

Your estimated project budget

Budget$ –

Thinner gauge panels with a standard paint finish.

Standard$ –

Mid-gauge panels with a durable factory finish.

Premium$ –

Heavy gauge, premium finish or a higher-cost market.

Rough planning figures based on US baseline assumptions, not a contractor quote. Actual contractor pricing may vary.

How this estimate is calculated
  • Roof area is multiplied by an installed price per square foot (materials and labor) for the metal roof type you choose, plus tear-off and disposal or the preparation needed to install over existing shingles.
  • If you enter a home footprint, roof area is estimated by adding 8% for overhangs and adjusting for pitch.
  • Steeper pitch, a more complex layout and taller buildings add labor. Complex roofs also need more trim, flashing and cut panels.
  • Roof deck condition adds an allowance for replacing damaged sheathing.
  • Each range is shown as about 10% either side of the calculated figure, then rounded.
  • Not included: permit fees, structural repairs, gutters, snow guards, skylight or chimney work.
