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.
Asphalt shingles cost slightly more than comparable fiberglass shingles, although the two products fall in the same general price range. In most cases, budget about $60-$120 per square for materials, $80-$200 per square for installation and $80-$150 per square for removal of the old shingles.1  For a 1,500-square-foot roof, the total cost for materials and installation would be $2,100-$4,800.ost fiberglass shingles fall in the range of $60-$120 per square, not including installation. A square covers 100 square feet. On the low end of that price range, youâll find 25-year shingles. On the high end, the shingles are often warrantied for life.
