  • National Average – base for calculation.
  • New England: +7.37%
  • Mid Atlantic: +6.67%
  • South Atlantic: -6.42%
  • East South Central -9.51%

How Are Roofing Costs Calculated?

These calculations are based on an average roof replacement job, which has the following specs:

Roof Size: 30 squares.
Slope: 4 in 12.
Dormers: 2
Valleys – about 80 ln. ft.
Chimneys: 1
Skylights: 2

Roof Installation Includes:

Tear off existing roofing down to the wood decks.
Install new felt underlayment.
Install new fiberglass asphalt shingles (min. 25-year warranty) – these would be 3-tab shingles ,
Install galvanized drip edge and mill-finish aluminum flashing.

The job includes about 5-squares of hip roof, custom flashing for two average-size skylights (these flashings are always provided by skylight manufacturers, so “custom” is a gimmick, and a premium vented ridge.

  1. We are a roofing company from Sofia, Bulgaria and we working with PVC/TPO membranes from 2002. Here in Europe, the value of a ready finished installed commercial roof with TPO membrane of 60mil is 1.15 USD/sqft. For us the shown in you website prices are crazy high.

  2. Living in Central Florida, is metal roofing less expensive during the fall and winter months vs. just before and during hurricane season?

    1. During & after hurricane, all roofing is MUCH MORE expensive, because of immense demand and short supply. My friend from Connecticut goes to Florida after hurricane and has work there for at least 3 months going forward.

      Because there is so much work, roofers can charge higher than normal prices. On top of that, shortage of materials further increases the costs.

      So it’s best to replace the roof during “off season” – during the winter.
