A new addition

Professional Roofing



2014; NRCA Roofing Manual; architectural metal flashing; condensation and air leakage control; reroofing

As indicated in the title, the 2014 volume specifically provides recommendations for air leakage control in roof assemblies. NRCA’s newly developed air leakage control guidelines address 2012 I-code requirements for building envelope air leakage control. The new content is among the revisions in the section titled Condensation and Air Leakage Control, formerly titled Condensation Control. As the final volume in the current set, the new manual benefits from the previous years’ work by NRCA’s Manual Update Committee. A significant number of revisions within the 2014 manual resulted from revisions the committee introduced in the earlier three volumes.
