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.
It depends on the type of roof. A single story low pitch asphalt shingle roof will cost around $40 - $80 per square (100 sq. ft.) to tear off and $75 - $100 per square to install new shingles. If the plywood sheathing underneath is damaged, it will cost extra, up to $50 per sheet replaced.Some contractors charge for flashing chimneys ($150 - $300) and pipes ($25). All labor performed on steep pitch roofs (7/12 and higher) will be about 10% or 15% higher. Two story housed may be 5% to 10% more.Other types of roofing have a wide range of prices. It really depends on which state you live and how steep the roof is and how many roofs already are on the house.ne of the most popular types of metal roofs being use â¦ d today is the 29 gauge thick exposed fastener panel, this type of roof typically cost from $2.25 to $4.00 per square foot complete with all materials and labor needed for instalation, depending on the complexity and difficulty of job.
