Standing seam roof

Metal roof panels (interlocking metal sheets with a minimum weather exposure of 3 square feet) may have different minimum allowable slopes depending on whether they are lapped, nonsoldered with or without lap sealant applied. With applied lap sealant, what is the minimum units vertical : units horizontal?
A. 1/4 vertical in 12 units horizontal (2%)
B. 1/2 vertical in 12 units horizontal (4%)
C. 2 vertical in 12 units horizontal (17%)
D. 3 vertical in 12 units horizontal (25%)

AnswerB. 1/2:12 or 4% slope. Without lap sealant, it's 3:12
