The problem was in the panel layout
The existing commercial metal roof on this Oklahoma City building used 25-foot panels across sections that were approximately 50 feet long. That layout meant each run needed a horizontal seam partway down the slope where two panels overlapped.
RedZone's project account identifies failures at those horizontal seams in several areas over time. Rather than chase the seams one by one, the replacement approach addressed the layout itself as part of a full metal roof and siding replacement.
The owner was not facing one isolated leak. According to the project account, the seam failures appeared in several areas over time, which pointed to the layout as the common thread rather than a single bad spot.
Why horizontal seams deserve attention
On a metal roof, any place where one panel overlaps another across the slope is a joint that water has to flow over. These end laps rely on correct overlap, sealant and fastening to stay watertight, and they can be affected by the roof's normal expansion and contraction. When a layout calls for many of them, each one is another detail that has to perform.
That is general background, not a diagnosis of any particular roof. What it explains is why, on this project, removing the intermediate seam was worth the extra effort.
Panels that span the whole section
RedZone installed 51-foot panels that ran the full length of each section without an intermediate horizontal seam. This changed the arrangement that had contributed to the earlier problems. Each panel now runs continuously from top to bottom.
The work also included new metal siding. The completed photographs show the finished roof from above, gray vertical metal siding around a loading-bay door, and the building with two RedZone trucks out front.
Planning for unusually long panels
Panels of that length do not handle like standard material. Handling them required additional planning, and RedZone's project account describes a custom platform built for a telehandler to lift and position the panels on the roof.
That was a project-specific installation approach, reflecting the practical handling needs of the selected material. It is a good example of why the installation plan belongs in the conversation alongside the material choice. A long panel solves a seam problem only if it can be moved and placed without damage.
Questions to ask about your own metal roof
On a metal roofing project, the finished look is only part of the story. The layout and installation plan deserve just as much attention.
- How long are the proposed panels, and where will any horizontal seams fall?
- How will penetrations, curbs and rooftop equipment be flashed?
- How are transitions to walls, gables and siding handled?
- What fastening and panel profile are proposed, and why?
- How will long material be delivered, staged and lifted on this site?
- Which manufacturer and workmanship warranties apply?
Plan your commercial metal roofing in Oklahoma City
If your building has recurring leaks at seams, laps or transitions, start with an inspection that looks at the layout as well as the condition of the panels. RedZone's commercial roofing team discusses metal, TPO and other low-slope options based on drainage, existing conditions, building use and budget, and coordinates access and scheduling around your operations.
