When moisture is present within a commercial roof system, the visible condition of the roof does not tell the entire story. The question is not simply whether moisture exists. The more important question is whether the data supports replacement, restoration, or another course of action.At this facility, Aerial Infrared (AIR) data gave the client that clarity.A 2021 AIR scan identified significant moisture within the existing Lightweight Concrete (LWC) roof system. A complete tear-off and replacement was estimated at $1,058,000. Instead of relying on assumptions about the roof's condition, RAM Companies used objective moisture data to support a more targeted strategy utilizing the Wind Vented System (WVS).The result was a $451,423 reduction in project cost, with subsequent aerial data documenting a significant reduction in moisture within the roof system.
The commercial facility had an existing Modified Bitumen roof over a Lightweight Concrete deck with an unvented metal deck.In 2021, RAM Companies collected Aerial Infrared data across the roof. The resulting imagery identified significant areas of moisture within the LWC insulation.The findings created an important capital planning question: Did the condition of the roof require a complete tear-off and replacement, or could the existing system support a more targeted approach?A complete replacement was estimated at $1,058,000. Beyond the capital required, a full tear-off would also remove existing roofing materials that would otherwise remain in place.The AIR data provided the visibility needed to evaluate the roof based on documented condition rather than assumption.Figure 1: 2021 AIR Scan showing significant moisture within the LWC insulation. Yellow, orange, and red areas represent identified moisture conditions. Data accurate as of the image date.
Based on the conditions documented through aerial infrared data, RAM Companies proposed a Wind Vented System instead of a complete roof replacement.The Wind Vented System uses negative pressure vents designed to facilitate moisture removal from the existing LWC system, providing an alternative to removing the entire assembly.
The difference represented a reduction of more than 42% compared with the estimated replacement cost.Just as important, the decision established a measurable baseline. Rather than completing the project and assuming performance, additional aerial data could be collected to evaluate changing moisture conditions over time.
The Wind Vented System was installed in 2022.RAM Companies subsequently collected follow-up AIR data in 2024. The new dataset showed a significant reduction in moisture within the LWC compared with the conditions identified in 2021.That before-and-after comparison is what makes the outcome measurable.The original scan documented extensive moisture conditions. The follow-up scan documented substantially less remaining moisture. Instead of relying solely on visual observations or assumptions about performance, the client had data showing how conditions had changed.Figure 2: 2024 AIR Scan showing significantly reduced moisture conditions following installation of the Wind Vented System. Pink areas represent remaining identified moisture. Data accurate as of the image date.
This project demonstrates why understanding actual roof conditions matters before committing capital.Without objective data, a facility team facing widespread moisture can be left with a costly assumption: replace the entire roof.The 2021 AIR scan created a different path. It identified where moisture was present and provided information that supported an alternative strategy. The 2024 scan then provided another dataset to evaluate the result.For this client, that approach avoided a full tear-off and replacement while reducing the project cost by $451,423.That is the value of roof intelligence. The objective is not simply to collect more information. The objective is to eliminate uncertainty so facility leaders can make defensible decisions about risk, timing, and capital.
RAM Companies delivers objective, high-resolution roof data that gives facility and portfolio leaders greater visibility into asset condition.For organizations managing large portfolios, standardized data collection creates a consistent foundation for prioritizing risk, allocating capital, and determining where spending is actually required.
