Every aging Fort Worth commercial roof faces the same decision: tear off and replace, or install a new system over what's there. The answer depends on facts we gather before we make a recommendation.

The replace-vs-recover decision is the first fork in the road for any Fort Worth commercial roof that's past the midpoint of its warranty life. It determines the project budget, the warranty path, the capital horizon, and the maintenance obligation going forward. Making the decision without data produces the wrong answer about as often as it produces the right one.

We gather the data before we give an opinion. That means pulling moisture cores in enough locations to characterize the insulation's moisture condition across the whole roof — not just the areas with visible damage. It means inspecting the deck under wet core locations. It means reviewing the existing warranty documents to understand what's still in force and what a recover vs. replacement would do to coverage. It means asking about the owner's capital horizon and what they're planning to do with the building over the next 10-20 years.

The deliverable is a written analysis with a documented recommendation — not a sales pitch for the more expensive option, not a rubber stamp on whatever the owner wants to hear, but an honest assessment of what the physical evidence supports and what the financial picture implies. Fort Worth building owners who go through this analysis before contracting with anyone get a recommendation they can take to any contractor and hold the contractor accountable against.

The Physical Evidence: What We Gather Before Any Recommendation

Moisture core sampling: We pull cores at five to ten locations on roofs up to 30,000 sq ft, with additional cores for larger roofs on a density proportional to the roof's size and prior leak history. Core locations are distributed across the roof — not clustered at known leak points, which would bias the sample toward wet areas. Each core is documented with a photo, a location on the zone diagram, and a wet/dry/borderline classification. We use the core results to estimate the percentage of the roof's insulation area that is wet.

Deck inspection: At wet core locations and at any point of visible deck deflection, we pull deck inspection ports to assess deck condition. On steel deck buildings — the majority of Fort Worth industrial and commercial construction — we look for rust, section loss, and fastener pull-through. On wood deck buildings, mostly in the Near Southside historic commercial inventory and in older retail strips west of downtown, we look for rot, delamination, and structural movement.

Existing system assessment: We document membrane condition (age, surface weathering, seam condition, blister count), flashing condition at every penetration type, drain condition, and the state of any prior repairs. Prior repairs that reveal themselves as recurring leak points indicate substrate problems that a recover would not address.

Hail-event history: We pull NOAA storm data for the address and cross-reference it with the roof's age and the documented repair history. Fort Worth roofs that went through the 2017 Cultural District hail event or the 2019 Tarrant County storm sequence without documented hail inspection may have un-repaired impact damage that affects the recover decision — you don't put a new system on top of damaged substrate.

The Decision Framework

Moisture threshold: If more than 25% of core samples read wet, we recommend full replacement. Recovering wet insulation traps the moisture, degrades the new system from below, and voids the incoming warranty. Most manufacturers will not issue an NDL warranty over insulation that tested wet at install — and if they do, the warranty excludes moisture-related failures. Below 25% wet, targeted insulation replacement at wet zones followed by a recover is a defensible path.

Deck condition: Any deck deterioration that requires structural repair eliminates the recover option for those areas — the deck work requires removing the existing system. If deck issues are widespread, the cost difference between repair-and-recover and full replacement narrows enough that replacement is often the more defensible scope.

Existing warranty status: If there is an active NDL warranty with years remaining, the recover decision has to be reviewed against the warranty terms. Many manufacturer warranties allow a recover (if the installer is a credentialed contractor and the new system is manufacturer-spec'd), but some require full tear-off to maintain coverage. We check the specific warranty language before making a recover recommendation.

Capital horizon: A building owner with a 4-year disposition horizon has a different math than an owner holding for 20 years. A recover that costs 55% of replacement and extends the roof 15 years is an excellent answer for a long-term holder; it may be a reasonable answer for a near-term seller if it stabilizes the asset for due diligence; it is a poor answer if the recover system won't outlast the hold period and the owner ends up paying for both the recover and a replacement during the hold.

Insurance and warranty interaction: The Fort Worth insurance market's approach to roofs is increasingly explicit about system age and condition. Buildings going through insurance renewal with roofs over 15 years old face underwriting questions that a documented recover-with-new-warranty answers better than a 'maintained existing system' narrative.

Facing the replace-vs-recover decision on a Fort Worth building?

We pull the moisture cores, inspect the deck, review the warranty status, and deliver a written recommendation that's backed by data — not by which option has a better margin for the contractor.
