Commercial Metal-Over-Metal Retrofit in Texas, Recover Without a Tear-Off

Here's a bit of context that usually helps before you price anything. A metal-over-metal retrofit is one path inside ARP's commercial metal roofing family, and it's the one that spares you a tear-off. It sits between two other decisions: doing nothing and watching the leaks spread, or ripping the whole roof off and starting over.

The retrofit only applies when your building already wears a metal roof. If you're re-roofing a building with a new metal system from the deck up, that's a standing seam conversation, not a recover, and it lives on the commercial standing seam page. If your existing metal roof is failing and you're weighing recover against a full replacement, you're on the right page.

Strip the jargon and a retrofit is straightforward. You keep the metal roof you have, and a new metal roof goes on over the top of it. The old roof stays put as a work platform, so the building stays dry the whole time.

The engineering that makes that work is the Roof Hugger sub-purlin system. Roof Hugger framing is a notched sub-purlin that seats down over the ribs of your existing panels, bridges the space between the old high points, and re-establishes a flat, structurally sound plane to attach to. The new panels fasten into that framing, not into the tired old fastener holes. Because the sub-purlin loads the new roof back into your building's existing purlins in a controlled, engineered pattern, the assembly meets the wind uplift numbers a Texas commercial roof has to hit.

That design buys you three things a tear-off can't. The old roof never leaves, so it works as a platform and there's no open deck exposed to weather mid-project. There's no disposal, so you skip the dumpsters, the landfill fees, and the crane time it takes to strip an old metal system. And your tenants keep working. On most retrofits the building stays occupied and dry from the first panel to the last, which is usually the whole reason a property manager calls about a recover in the first place.

ARP is a lead Roof Hugger installer, and on a retrofit that experience is the job. The recover lives or dies on how the new fastener pattern loads back into the existing purlins, and getting that attachment right is what separates a 40-year roof from a callback in year six.

This is the whole decision, so let's be straight about it. A metal-over-metal retrofit is the smarter money about the time your building's bones are still good. It is the expensive shortcut the rest of the time. The line between the two is structural, and it's the first thing an ARP estimator reads when walking your roof.

A retrofit is the right call when:

• The structure underneath is sound. Your purlins, deck, and framing can carry the added load of a sub-purlin and a new panel. Most metal buildings can, but it gets confirmed on the roof, not assumed from the parking lot.
• The existing metal is leaking at the seams and fasteners, not rusted through. Aging washers, backed-out screws, and worn end laps are exactly what a recover is built to solve. The panel itself is tired at the connections, not gone.
• You want to stay open and avoid disposal. Occupied buildings, tenants you can't displace, and the cost and mess of hauling an old metal system all push the math toward recover.

A retrofit is the wrong call, and a full tear-off-and-replace is the honest answer, when:

• The existing metal is rusted through or the deck is structurally tired. You cannot build a 40-year roof on a substrate that's already failing. Covering a rusted deck just seals the problem in and hands you the same bill again in a few years.
• The structure can't take the added load. If the framing is already maxed out, the retrofit needs structural work first, which changes the whole equation.
• Trapped moisture or prior damage has compromised what's underneath. Recovering over a hidden problem is how a shortcut turns into the most expensive roof a building owner ever buys.

The candidacy question, recover versus tear off, is the entire conversation, and the answer comes from the assessment rather than the sales pitch. When the structure is sound, recover beats replace on cost and on disruption every time. When it isn't, ARP will tell you that a full commercial roof replacement is the right spend, even though it's the bigger one. That's the answer you want from the company that has to warranty the result.

A commercial metal-over-metal retrofit in Texas runs $10 to $12 per square foot installed, Roof Hugger framing and new panels included. A 10,000-square-foot roof lands near $131,000 to $157,500, well under a full tear-off. Final price depends on deck, drainage, prep, and access.

The table below is a Texas baseline for a metal-over-metal recover. Actual roof area runs larger than a building's stated floor area once you account for pitch and overhangs, so the totals are keyed to approximate roof square footage.

That $10 to $12 per square foot covers the Roof Hugger sub-purlin framing, the new metal panels and fasteners, the flashing details, and the full ARP scope: a structural assessment with photos, a written scope before you sign, manufacturer-specified installation, and a final walkthrough. The number moves with the sub-purlin gauge and spacing your wind zone requires, how much slope or drainage correction the roof needs, how much prep the old surface takes, and how hard the roof is to reach and stage. As with any commercial system, the final price depends on your existing roof condition, deck substrate, drainage requirements, and access complexity.

Here's why the recover math works. A full tear-off-and-replace runs higher because you're paying to strip and haul the old system before the new one goes on:

The retrofit lands below a tear-off on a roof that qualifies, and it does it without closing your building. The full commercial metal breakdown, with sample totals by building size and system, lives in the commercial metal roofing cost guide.

A recover is only as good as the framing pattern under it and the warranty behind it. Metal-over-metal is a specialty, not a sideline, because the retrofit is an attachment problem before it's a panel problem. Three things back every ARP metal retrofit:

• We're a lead Roof Hugger installer. The sub-purlin system is what makes a recover hold, and specifying and setting that framing correctly is on-staff experience here, not something subbed out to whoever's available.
• GAF GoldElite Commercial Contractor. ARP holds GAF's top commercial designation, which anchors the rest of our commercial work across EverGuard single-ply. Metal itself is largely site-formed and brand-agnostic, so what actually backs your retrofit is the panel gauge, the Galvalume and the Kynar 500 / PVDF finish, and the engineered fastening schedule, not a sticker.
• Everything is documented. A structural assessment with photos, a written scope before signing, and a warranty ARP personally backs.

A metal retrofit isn't right for every roof or every owner. Here's the honest read.

You're probably the right fit if you:

• Manage a commercial or industrial building in Texas with an aging metal roof that's sound underneath but leaking at the seams and fasteners
• Want a structural assessment and a written scope before anyone touches the roof, every time
• Need to keep the building occupied and dry through the project instead of shutting down for a tear-off
• Need photo documentation to justify the capital spend to ownership
• Plan to hold the property long-term and want a partner, not one transaction

You're probably not the right fit if you:

• Need the lowest number in the market, a priority we respect but can't always match
• Have a metal roof that's rusted through or a deck that no recover can honestly carry
• Want work to start within 24 hours with no assessment and no documentation
• Manage a building under roughly 1,000 sq ft, where our minimum scope isn't economical

If you want to make a six-figure roof decision with the structural read and the real numbers in front of you, book a commercial metal assessment and we'll put the scope and the pricing on paper before anything is decided.

Whether you hire ARP or someone else, ask every contractor who bids a metal recover these three. The answers tell you more than any rating.

1. "Are you engineering the attachment with a real sub-purlin system, or just laying panels over the old roof?" A metal-over-metal retrofit needs an engineered sub-purlin, like Roof Hugger, that loads the new fasteners back into the existing purlins and hits your wind uplift numbers. If the answer is "we just screw the new panels down over the old ones," walk away. That's how a recover turns into a callback.

2. "Will you confirm the structure and check for rust-through before you quote the recover?" A retrofit over a rusted-through deck or a maxed-out frame seals the problem in and fails early. A contractor who quotes a recover from the ground, without reading the structure and the fastener condition on the roof, is gambling with your capital budget. The structural read is the entire decision.

3. "Show me the written scope, panel gauge, finish, and fastening schedule before I sign anything." A real retrofit proposal names the sub-purlin spec, the panel gauge, the Galvalume and Kynar/PVDF finish, and the engineered clip and fastener pattern, in writing, before a deposit. Vague quotes are where recovered metal roofs leak in year eight.
