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.
1 The above figures place the cost of the addition at $124 per square foot. 2  This pricing structure assumes that carpenters charge an average of $70 per hour, electricians between $65 to $85 per hour, and painters between $20 and $35 per hour. According to Hanley Wood and their Remodeling magazine the average basic addition in which a foundation is added, vinyl siding is applied, adequate roofing is done, interior walls are insulated and finished, new carpet and windows are installed and all electrical and HVAC works is completed will cost $23,804.
