A built-up roof system requires 4 plies of felt with hot asphalt. If the roof area is 8,500 square feet and asphalt coverage is 25 pounds per 100 square feet per ply, how many pounds of asphalt are needed?
Correct Answer
C) 8,500 pounds
Asphalt per ply = 8,500 sq ft × (25 lbs/100 sq ft) = 2,125 lbs. For 4 plies: 2,125 × 4 = 8,500 pounds.
Why This Is the Correct Answer
Asphalt per ply = 8,500 sq ft × (25 lbs/100 sq ft) = 2,125 lbs. For 4 plies: 2,125 × 4 = 8,500 pounds.
