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.
Raising the pitch of a roof often requires not only tresses but new supports, new roofing and, in the end, a full replacement of the rooftop itself. According to Costhelper.com, a typical new shingle roof can cost between $1,700 and $8,400 to have built.
