Abstract
When reroofing, there are two basic options for both low and steep sope roofs; either tear off the existing membrane and insulation down to the roof deck, or leave the existing roof covering in place and add a new membrane (and perhaps insulation) over it. While the recover option is not new, there appears to be some disturbing trends appearing in articles in other trade publications advocating this approach. The recover option is now cited as an answer to minimizing waste disposal costs. And there appears to be a re-emergence of the concept of leaving insulation with a high moisture content in place.
