I paid almost $13,000 to have Duration Premium shingles installed on my central Florida home in late 2007. I went with Owens Corning Duration Premium shingles because of their premium quality, their lifetime warranty and their high wind resistance. Within 3 months of the installation, I started having leaks.
Local labor and material costs and the difficulty of the installation can result in significant price differences. 1  Standard 3 tab asphalt shingles installation costs approximately $2.50 to $4.50 per square foot. For a roof measuring 1,500 square feet, the total cost might be around $3,750 to $6,750. At this price, you can expect a warranty of approximately 20 to 30 years. Architectural roof shingles cost approximately $5 to $10 per square foot installed, or roughly $7,500 to $15,000 for a 1,500 square foot roof. These higher quality asphalt shingles should come with a 40 year warranty.
