About Roof HuggerRoof Hugger notched sub-purlins enable replacement of new metal roof panels over an old metal roof. They can be used over
screw-down or standing seam roof systems and can accommodate new standing seam or screw-down panels. Roof Huggers also maintain integrity of original design loadings; achieve "thermal break" air space between old and new roof sheets; allow for
optional insulation; and are laboratory and load tested—with certified load charts. For more information on metal-over-metal retrofit re-roofing, contact Roof Hugger at 800-771-1711 or visit www.roofhugger.com.
