What is the maximum size sheet for EPDM membrane?

There is a difference between 'maximum size' - 'practically available maximum size' and 'practical to use maximum size'.

It is readily available in rolls large enough to do your house without leaking, and with a minimum of planning.

I've never used the stuff on a roof. [my pond is lined with it, though] It glues readily, and takes a crap-load of abuse. . . . and is heavier than all get out. I would think that a roll a foot wider than one flat on your roof should be plenty heavy to manhandle on a roof.

Can any roofers expound on my *theory*.
