A mil is a unit of measure where 1 mil is equal to 0 001 inches. The bottom layer of a single ply membrane roofing system is the roof deck or substrate.

Rigid foam insulation installation prepare roof deck. Whereas a 60 mil membrane is 0 06 inches thick and so on. So a 45 mil roofing membrane is actually 0 045 inches thick. When it comes to estimating the weight of an existing roof field verification of the in place construction is necessary.

If the tapered maximum thickness exceeds that permitted by 457 a thermal barrier may be required. Built up 3 8 thick plies. The most common thickness is probably 60 mils. Also see below at wood.
