Commercial Roof Recover

Problem Roof? Recover! McElroy Metal's industry-leading roof recover systems offer building owners a long-term, economical solution without costly removal and replacement for aging commercial roofs.

roof recoverRemove and replace is a common but often unnecessary roof replacement method. Recover roofing solutions entail installing a new roof directly over existing, worn-out metal or shingle roofs.

Metal-Over-Metal and Metal-Over-Shingles Solutions

McElroy Metal offers innovative and proven recover solutions for both metal-over-metal and metal-over-shingle applications. Both solutions provide the following benefits:

  • Symmetrical standing seam panels
  • Eliminates the expense and hassle of existing roof tear-off
  • More economical
  • Symmetrical panels are replaceable in the event of future damage or roof changes
  • Energy Efficiency

A Closer Look at the 238T Metal-Over-Metal Recover System

McElroy Metal's 238T frameless Metal-Over-Metal recover system provides a low-cost reroof solution over existing exposed fastener metal panels. This system utilizes McElroy's easily repairable 238T symmetrical standing seam panel while providing a long-term solution for existing metal roofs that have completed their service life.

McElroy’s Metal-Over-Metal recover system is competitive with single-ply recover and will last two (2) to four (4) times longer at a cost that is less than removing and replacing.

A Closer Look at the 138T Shingle Recover System


For commercial buildings with existing shingle roofs, McElroy’s 138T Shingle Recover System offers a long-term, economical solution.

This system is installed directly over existing shingles and utilizes patented clips to create above sheathing ventilation (ASV). ASV air-spaces enable airflow under the metal roof which allows air to circulate and vent into the atmosphere resulting in lower utility expense.

Check out the animation video below showing the 138T installation process.


Individual panel replaceability is an advantage of both 138T and 238T systems. In the event of roof panel damage or roof changes due to rooftop mechanical equipment modifications, individual panels can be replaced.
