TPO or PVC membrane (as found)

The table

40 lb a squareThe sources give 29 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 sheet weighs 29 to 44 lb a square (Carlisle, Johns Manville, Sika); 40 lb is the figure. Xactimate disposes of a torn-off square at 300 lb (6.66 squares a ton), far above any sheet; its definition does not say what else it counts, so it stands as the high end. Insulation and cover board coming off are their own entries.
