238T Metal-Over-Metal Recover – Standing Seam Metal Roof System
Recover aging metal roofs quickly and cleanly—without tear-off or disruption.
McElroy Metal’s 238T Metal-Over-Metal Recover System installs directly over existing metal roofs, providing a frameless, long-term replacement solution without tear-off or disposal. Its symmetrical standing seam design allows installers to start or stop anywhere on the roof and remove or replace individual panels as needed.

238T Metal-Over-Metal Recover Ideal Applications
-
Commercial, industrial, and institutional buildings with aging metal roofs.

238T Metal-Over-Metal Recover Top 3 Benefits
-
No Tear-Off Required: Installs directly over existing metal roofs, saving time, labor, and disposal costs.
-
Individual Panel Replaceability: The symmetrical 238T design allows individual panels to be removed or replaced anywhere on the roof.
