Estimate the total cost and the cost per square for furnishing and laying three-tab asphalt shingles on a wood roof decking whose area is 4,800 sf. The roof will have numerous valleys, hips, and dormers. Reference table 13.2 for the representative labor-hours. A 15-lb roofing felt underlayment will be installed prior to installing three-tab, 235-lb asphalt shingles. The labor-hours for installing roofing felt is known to be 0.5 hour/square. Assume material costs of felt, shingles, and nails as $3.40/square, $55.00/square, and $1.45/lb, respectively. Labor costs of carpenters and laborers are $28.00/hr and $21.00/hr, respectively
