Reroofing Clarifications Explained In New Resource

Roof Replacement Projects May Require Energy Code Updates

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.

“Billions of square feet of low-slope of commercial roofs (roofs with insulation above the deck) are replaced every year in the United States,” said Jared Blum, President, PIMA. “The clarification in the IECC means that whenever an existing low-slope roofing membrane is removed before a new roofing membrane is installed, the underlying roof insulation must be brought up to current code-mandated R-value levels.”

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.

The new brochure, similar in format to many other IMT brochures, contains:

  • A detailed listing of the key definitions and energy regulations that apply to commercial roofing;
  • Illustrations of typical roofing conditions; and
  • A decision tree to determine the specific compliance path for any roofing application. 

“Because it is considered a clarification rather than a new addition to the code, officials can start enforcing the update now and don’t have to wait until the 2015 version of the IECC is adopted in their jurisdiction. This brochure is succinct, easy to follow and clearly explains how to comply with the clarification,” added Blum.

“The International Energy Conservation Code as Applied to Commercial Roofing” brochure will help local code officials better understand the energy efficiency requirements for all types of commercial roofing projects and also serve as a useful guide to explain the code requirements to roofing contractors seeking construction permits, design professionals (architects, engineers, roof consultants) involved in roofing selection and specification, as well as building owners as the ultimate end-user of the code.

“The brochure is a part of a comprehensive effort by PIMA to inform members of the design community about their legal obligations to comply with the reroofing energy upgrade requirement,” added Blum.

In addition to advocating for increased building energy efficiency via improved building codes, IMT also works to increase compliance with energy codes by developing and distributing informational materials suitable for use in local code jurisdictions, not only for code officials but also for owners, designers, and contractors.
