These are rough estimates of what a roofing company costs to install a new roof or replace an existing one and are intended as a starting point only. For licensed and insured roofing contractors, add about 5 per cent to the cost.

Costs can differ enormously depending on where in the United States you live, the size of the home or unit and whether its single storey or multiple storeys, the "tear-off" time it takes to remove an existing roof, the pitch (slope) of the roof, whether attic windows or skylights are to be installed, the types of materials being used to cover the roof, accessibility, and (in the instance of replacing a roof) whether beams and other structures in the roof need to be partly (or wholly) replaced.

You need to contact roofing contractors and roof companies and get at least three quotes in order to get a reasonable idea of how much it will cost to install a new roof or replace an existing one.
