A lot of the roofs we're called out to inspect around Vanderburgh and Warrick counties have already been recovered once, sometimes twice, before we ever see them. Deciding whether another recover makes sense or whether it's time for a full tear-off isn't a judgment call we make from the ground, it comes from what's actually inside the roof assembly.
A recover, installing a new membrane over the existing roof rather than tearing it off, works when the existing insulation is dry, the deck is structurally sound, and building code allows another layer. It costs less than a full tear-off and generates less disruption for occupied buildings, which matters on hospital campuses and active manufacturing plants where downtime has a real cost.
On plant buildings around the manufacturing base near US-41, where production can't stop for an extended roof project, a properly evaluated recover often gets the roof back to full performance without the schedule disruption a tear-off requires.
Retail and office buildings undergoing a broader renovation or tenant improvement project sometimes bundle a roof recover into that larger scope, since access equipment and site logistics are already in place for other construction work happening at the same time.
Most commercial building codes cap the number of roof layers allowed before a full tear-off is required, and older downtown buildings that have already been recovered once or twice are often already at or near that limit. We check the roof's layer history, through visual inspection or existing records, before recommending a recover as an option at all.
Beyond the code limit, added weight from multiple recover layers is a real structural consideration on older buildings, particularly ones not originally engineered with extra dead-load capacity for a stacked roof assembly.
We also check whether a previous recover was documented with a permit, since undocumented prior work sometimes surfaces during a moisture scan or deck inspection in ways that change the layer count assumption a building owner started with.
Wet insulation underneath an existing roof does not dry out under a new membrane, it gets sealed in permanently, continuing to degrade and eventually causing the new roof to fail from underneath. An infrared or capacitance moisture scan identifies wet areas before we recommend anything, and it's a step we won't skip regardless of how confident a visual inspection looks.
Infrared scanning works best performed after sunset, once the roof surface has absorbed a full day of heat and wet insulation areas retain that heat differently than dry sections, which is why we schedule scans for evening hours rather than midday.
A recover bid that skips the moisture scan step is a bid that's guessing at what's actually inside your roof assembly, and that guess tends to come due a few years later as a leak that's much more expensive to trace and fix than it would have been to catch upfront.
Once a recover is confirmed as viable, the process typically includes cleaning and repairing the existing surface, addressing any localized wet insulation with cut-out and patch repairs, and installing the new membrane system over the prepared substrate. On a recover project we confirm:
For hospital buildings at Deaconess or Ascension St. Vincent campuses, or manufacturing plants that can't shut down production, the downtime difference between a recover and a full tear-off is often the deciding factor once both options are structurally viable. We lay out both paths honestly, including what a moisture scan found, so building owners can weigh cost and disruption against long-term roof performance themselves.
Phased recover projects, where a large roof gets divided into sections completed over several weeks rather than all at once, are common on manufacturing plants that need at least partial roof coverage in service at all times during the project.
We also document our findings clearly, including moisture scan results and code layer counts, which is useful reference material for future capital planning even beyond the immediate project decision.
It comes down to existing layer count against code limits, dry insulation confirmed by a moisture scan, and adequate structural capacity, all of which we check before recommending it.
Usually, but not always once repair work for wet insulation is factored in. We give a real comparison rather than assuming recover is automatically the lower-cost path.
We identify the affected area for cut-out and repair, or recommend tear-off instead if the wet area is extensive enough that patching isn't practical.
Often yes, with proper phasing and coordination around occupied and critical sections, which is part of how we scope healthcare roof projects.
Limits vary by code edition and jurisdiction, which is why we check the applicable code and the roof's actual layer history before proposing another recover.
