Scissor Truss Over Existing Roof

For a 2 000 square foot home roof truss installation typically costs between 7 200 and 12 000 you ll spend anywhere from 1 50 to 4 50 per square foot for materials alone or between 35 and 150 though extremely long and complex types can reach 400 each labor runs anywhere from 20 to 75 per hour ranges in both materials and labor are due to location size and roof complexity.
