HOW MUCH DOES A NEW ROOF COST?

These factors will determine where your shingle replacement cost falls on the spectrum for single-story and two-story homes:

• Quality of the shingles: Basic, Better or Best
• Tear-off or Not: Most local building codes allow for two layers of asphalt shingles. When old shingles are torn off, new roofing paper, starter shingles, ridge vent and moisture barrier are installed.
• The complexity of the roof: The more peaks, valleys, skylights and other obstacles the roof has, the higher the installation cost will be. Ranch homes, for example, are much easier to roof than Tudor or Victorian styles.
• Who Does the Work: Unlicensed roofers charge less than licensed roofers. However, most shingle manufacturers don’t honor their warranties unless the roof is installed by a licensed installer.
• The Warranty Protection you Want: Owens Corning, CertainTeed, GAF and other manufacturers offer several warranty packages in Basic/Better/Best coverage. To get the best warranties, your roofing project must include the brand’s best accessory materials including premium roofing paper, moisture barrier and starter shingles.
• High Wind-zone Installation: Most dimensional shingles have a 110MPH wind warranty. It can be increased to 130MPH with enhanced shingle installation using more nails and roofing cement at a higher cost.
• Slope of the roof: The estimates above for how many square feet of roofing average single-story and two-story homes have are based on a roof with a 6/12 slope.
