Roof Recover and Overlay Systems in Springfield, MO
The Moisture Survey a Recover Bid Should Never Skip
A recover - installing a new membrane over an existing roof rather than tearing it off - can save real money on disposal and labor, but it only works when the roof underneath actually supports building on top of it, and that is where a lot of recover bids cut a corner.
Skipping the Moisture Survey Is the Most Expensive Shortcut in the Business
Wet insulation trapped under a new recover membrane does not dry out - it stays wet, keeps degrading the deck underneath, and eventually forces a tear-off anyway, except now there are two membranes to remove instead of one. A bid that quotes a recover price without a moisture survey is pricing based on hope, not on what is actually under the existing membrane.
We run an infrared or capacitance moisture scan before quoting any recover, and we mark wet areas on the roof plan so the owner can see exactly where the existing roof has already failed, even if the surface still looks intact.
Code Layer Limits Aren't Optional, Even If a Bid Ignores Them
Building codes limit how many roof layers a structure can carry, and a roof that has already been recovered once is frequently already at that limit, meaning a second recover requires tearing off at least the top layer regardless of what a bid promises. Ignoring the layer count and quoting a straightforward recover on a roof that legally cannot take another layer sets up a change order the moment an inspector gets involved.
We check layer history before quoting, using existing documentation or a core sample where records are not available, so the recommended scope is one that can actually be permitted and built, beyond simply priced.
What a Recover Board Actually Buys You Beyond a New Membrane
A quality recover system includes a cover board over the existing roof before the new membrane goes down, adding insulation value, a smoother substrate for the new membrane to adhere or attach to, and additional puncture resistance against hail and rooftop foot traffic. Skipping the cover board to cut cost undermines several of the performance benefits a recover is supposed to deliver.
We include a cover board as standard on our recover systems rather than treating it as an optional upgrade, because the membrane's long-term performance depends on what it is adhered or fastened to underneath.
A recover is usually the wrong call, and tear-off the right one, in situations like these:
- Moisture scan shows wet insulation across a significant portion of the roof
- The building has already been recovered once and is at the code layer limit
- Deck damage is suspected from a prior leak history that was never fully repaired
- Rooftop equipment needs curb height changes that a recover layer would complicate further
- The owner plans a long-term hold where tear-off's higher upfront cost pays off over time
When a Recover Is the Wrong Call
A recover is not always the cheaper or smarter option, and there are situations where it just delays a more expensive problem to a later date when the deck damage has spread further and the tear-off costs more than it would today.
What a Complete Recover Bid Should Include
A complete bid includes documented moisture scan results, confirmed layer count against local code limits, and a stated cover board specification rather than a bare membrane-only price.
It should also address roof edge and curb height changes, since adding a recover layer raises the roof surface and can affect flashing height at existing curbs, parapets, and doors that open onto the roof.
Questions We Get About Roof Recover and Overlay
How do I know if my roof can be recovered instead of torn off?
It comes down to a documented moisture scan and a check against local code layer limits. A dry substrate at or below the allowed layer count is a good recover candidate; a wet or already-layered roof usually is not, no matter how good the surface still looks.
Does a recover cost significantly less than a tear-off?
Generally yes, mainly from avoided disposal and labor costs, but the savings only hold up if the existing roof is actually in condition to support it. A recover installed over a problem roof ends up costing more overall once it fails early and needs to be removed anyway.
What happens to rooftop equipment curbs during a recover?
Curb height needs to be extended to match the new, slightly raised roof surface, and that detail should be priced into the recover bid rather than discovered as a change order once the crew is on site.
Can a metal roof be recovered with a single-ply membrane?
In some cases, using a system designed specifically for that transition, though it depends on panel condition, slope, and how the seams are handled underneath. We evaluate it case by case rather than assuming it always works the way it does on a low-slope roof.
How long does a recover system typically last compared to tear-off and replace?
A well-executed recover over a sound substrate can perform comparably to new construction for many years, but it depends heavily on the condition of what it was built over, which is exactly why the moisture survey and layer check matter so much before committing to the approach rather than after the new membrane is already down.
