What is the minimum pitch for an EPDM roof?

(A minimum slope of 0.25 inches per foot [2 percent] is recommended for all low-slope roofing systems.) For adhered systems, the substrate must be one that is approved by the system supplier. Higher-density products provide improved impact resistance.

Does EPDM have to be glued down?
