Ins and Outs of Reroofing
Reroofing of existing buildings—both replacement and re-covering—is roughly 75 percent of the roofing industry. To that end, understanding how to determine whether a building requires a roof replacement or re-cover is key to a successful reroofing project. Reroofing-specific code requirements, investigation methods, and analysis of decks and insulation will be discussed, as well as the necessary aspects of wind resistance and energy efficiency upgrades (insulation, air barriers). In addition, the presentation will provide information to assist with the design and installation of flashing details given existing conditions.
