Whether you are rebuilding your old roof or constructing a new house, the cost of asphalt shingled roofing is not something that should be taken lightly. The general cost of the asphalt shingles themselves is between $0.43 and $2. This translates to about $700 to $4,000 for a 1,600 to 2,200 square foot roof. When you factor in labor, a contracted job will generally cost twice as much, a total of $1 to $4 per square foot. This results in a charge of $1,600 to $8,500 for the same job mentioned above.
