Recover Systems: Getting a New Roof Without Tearing Off the Old One
Recover is the strategy we reach for most in Shreveport-Bossier, given how much of this market's commercial building stock is older and still watertight enough to build on rather than demolish. Installing a new membrane over an existing roof - instead of tearing the old system off first - keeps a building dry throughout construction and generally costs less than full replacement, provided the roof underneath qualifies.
Why Recover Fits So Much of This Market
Manufacturing plants, casino properties, and medical office buildings across Shreveport-Bossier were often built with multi-ply asphalt roofs designed for a long service life through periodic maintenance. When that original roof reaches the point where patching no longer keeps up, a lot of facilities managers assume the next step is full tear-off. Often it isn't. If the deck and insulation underneath are still dry and structurally sound, recovering over that roof with a new membrane - TPO, PVC, or another cap sheet system - gets you a new roof surface at meaningfully lower cost, with far less disruption to operations below.
The Moisture Survey: The Step That Decides Everything
Every recover conversation we have starts with a moisture survey of the existing roof, usually done with infrared scanning or core sampling in representative areas. This tells us whether water has already worked into the insulation or deck. If it has, recovering over it just traps that moisture under a new membrane, where it keeps degrading the roof from the inside while looking fine on the surface. That's the scenario we're most careful to rule out before recommending recover, because a recover job that fails early costs more in the long run than an honest tear-off recommendation up front.
Code Limits on Roof Layers
Building code generally limits how many roof layers a structure can carry before a full tear-off becomes mandatory, and that limit varies depending on what's already up there. If your building has already been recovered once before, we check the layer count and code requirements before scoping another recover, since some buildings are already at their limit and need tear-off regardless of deck condition.
What a Recover Project Typically Involves
- Moisture survey across the existing roof to confirm dry, sound substrate
- Verification of existing roof layer count against current code limits
- Removal of loose gravel, blistered sections, or other unstable surfacing
- New insulation layer where slope correction or added R-value is needed
- New membrane installation - TPO, PVC, or modified bitumen depending on building needs
- Full detail work at drains, curbs, penetrations, and perimeter edge metal
The membrane choice depends on what's actually happening on your roof - chemical or grease exposure points toward PVC, a straightforward warehouse field usually runs TPO, and buildings already dealing with granulated cap sheet often stay in that family with modified bitumen. We can walk through TPO options in more detail depending on what your building actually needs.
Cost and Downtime Compared to Full Tear-Off
Recover generally costs less per square foot than full tear-off and replacement, since you're not paying for demolition, disposal, or the added labor of removing an existing system before installing the new one. It also keeps the building weathertight throughout the project instead of opening the deck to sky during construction, which matters for a casino floor, a production line, or patient space below that can't tolerate any exposure risk. We'll run both numbers for you - recover now versus tear-off now versus deferred tear-off after more patch repairs - so the decision is based on your building's real condition and your budget cycle, not a default assumption either way.
When Recover Isn't the Right Call
We turn down recover scopes more often than people expect. If a moisture survey shows widespread wet insulation, if the deck has structural issues, or if the building is already at its code-allowed layer limit, recommending recover anyway just sets you up for a failed roof and a wasted budget line a few years down the road. In those situations we'll walk you through what a proper tear-off actually costs and why it's the more honest answer, even though it's a bigger number upfront than the recover quote would have been.
If you're managing more than one property across Shreveport-Bossier with roofs of similar age and construction, it's also worth having each one surveyed on the same visit rather than reacting to leak calls one building at a time. That gives you a real picture of which roofs are strong recover candidates, which need tear-off soon, and which can wait - useful information for building a multi-year capital plan instead of budgeting roof work one emergency at a time.
Common Questions About Roof Recover and Overlay Systems
How do we know if our roof qualifies for recover instead of tear-off?
A moisture survey and a check of existing roof layers against code limits tells us. We do both before quoting anything.
Is recover actually cheaper than tear-off long term?
Usually cheaper up front, and often cheaper overall if the existing roof is a good candidate. We'll show you both numbers so you can decide based on your capital plan.
What happens if the moisture survey finds wet insulation?
We'll recommend tear-off for the affected areas rather than recovering over trapped moisture, even though that's a less convenient answer.
Can any membrane be used for a recover, or does it depend on the existing roof?
It depends on what's underneath and what the building needs going forward - we'll recommend TPO, PVC, or a modified bitumen cap sheet based on your specific situation.
How many times can a roof be recovered before it has to come off?
It depends on code limits for your jurisdiction and the layers already in place. We check that before scoping any additional recover.
