EPDM rubber (as found)

Its weight

The table
43 lb a squareThe sources give 30 to 300 lb.
Loose volume
Not known: it counts in the tons aloneNo source found gives a loose debris volume for torn-off membrane; it rolls or folds, and a hauler's volume for it was not found.
How it was chosen
A 60-mil EPDM sheet, the common one, weighs 40 to 47 lb a square (Firestone 0.43 lb a square foot); 43 lb is the figure. Xactimate disposes of a torn-off square at 300 lb (6.66 squares a ton); its definition does not say what else it counts, so it stands as the high end. Ballast and insulation coming off are their own entries.
