When it comes to installing or repairing a roof, labor and materials are going to drive up the most costs. Paying a crew for their professional installation skills accounts for 20-30% of the overall cost of your roof replacement. This includes the careful removal and disposal of the old roof and underlayment. Costs may vary depending on the size and angles of your roof.
Roofing materials are generally expensive, and between 70-80% of the overall cost goes to materials. Materials can also include accessories such as fresh drip edges, fasteners, new ventilation, and new flashing.
Equipment is another factor that can affect the cost of a roofing project. This category may include equipment such as roof jacks, shingle cutters, air compressors, pneumatic nailers, liability insurance, and fuel.
