Energy Code Brochure Explains New Reroofing Clarifications in 2015 IECC
A new energy code brochure, “The International Energy Conservation Code as Applied to Commercial Roofing,” has been released explaining reroofing clarifications in the 2015 International Energy Conservation Code (IECC). The reroofing clarifications make it very clear that almost every commercial reroofing project involving the removal and replacement of the existing roof covering must be upgraded to the current IECC R-value levels.
The Institute for Market Transformation (IMT), with the assistance of the Center for Environmental Innovation in Roofing (the Center) and the Polyisocyanurate Insulation Manufacturers Associations (PIMA), developed and released the new energy code brochure.
The new code clarification establishes specific definitions for each major type of roofing activity that may occur on a commercial building:
Reroofing. The process of recovering or replacing an existing roof covering. See “Roof Recover” and “Roof Replacement.”
Roof Recover. The process of installing an additional roof covering over a prepared existing roof covering without removing the existing roof covering.
Roof Replacement. The process of removing an existing roof covering, repairing any damaged substrate and installing a new roof covering.
Roof Repair. Reconstruction or renewal of any part of an existing roof for the purposes of its maintenance.
