Gable Roof Costs. The following costs are based on roof installation during new home construction. Changing your existing roof to a gable roof can easily add $5,000 to $10,000 to the project cost. As a VERY general guideline, labor for framing a gable roof costs $8 to $12 per square foot of roof surface. For an average 1,500 square foot roof this works out to $12,000 to $18,000. Multiple gables and dormers can result in prices as high as $25,000.
Decorative dormers range from $583 to $933, according to a 2013 report by Dryden Mutual Insurance. An average 10-by-15 shed dormer costs between $11,270 and $16,904, while the same size gable dormer ranges from $14,400 to $21,602.ut this extra bit of headroom comes with a high price tag, and dormer installation is not a DIY project. Plan to spend between $10,000 and $30,000 for your new dormer, depending on size and style.
