An asphalt-shingle roof has a slope of 3:12. Under the IBC low-slope asphalt-shingle provisions, what underlayment arrangement is required?
Correct Answer
C) Two layers of underlayment applied as prescribed for slopes from 2:12 up to less than 4:12
For asphalt shingles on slopes from 2:12 up to less than 4:12, the IBC requires the two-layer underlayment method. Other choices omit the low-slope requirement, use the steeper-slope single-layer approach, or turn the ice-barrier rule into full-roof underlayment.
