What is involved in re-roofing over LWIC?
In many instances, it may be acceptable to cast LWIC directly over an existing membrane and insulation system. If the membrane is removed and there are base sheet nails of holes left on the deck, they shall be handled per specific job conditions. Unlike insulation board systems, just remove the existing membrane and install a new membrane per local requirements for acceptability. The LWIC system is permanent and does not need to be replaced.
