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.
In a 2014 report, Dryden Mutual Insurance Company estimates the cost of basic shed dormers, where the roof of the dormer slopes out away from the house, at $11,647 to $17,470. Fancier gabled dormers with peaked roofs ring in between $14,883 and $22,235.n areas prone to seismic activity, for example, adding a large attic dormer to raise the roof may require a whole-house seismic upgrade. Other homeowners may face costs associated with beefing up roof trusses to support the weight of the new living area.
