What is the best way to evaluate whether low-slope roofing systems should be recovered or replaced?

The most effective method for evaluating whether low-slope roofing systems should be recovered or replaced is to conduct test cuts as part of the evaluation of the existing roof. This approach provides a comprehensive assessment of the roof's structure, materials, and underlying conditions.

Test cuts allow the inspector to examine multiple layers of the roofing system, providing insights into moisture intrusion, the integrity of insulation, and the overall condition of the roofing materials beneath the surface. By obtaining a detailed analysis of the roof's components, it becomes possible to determine whether the roof can be effectively recovered or if a full replacement is necessary due to significant deterioration or structural issues. This proactive approach not only aids in accurate decision-making but also helps in planning the appropriate course of action to ensure the longevity and performance of the roofing system.

Visual inspections alone may provide an overview of surface conditions but often miss critical hidden problems that a more invasive procedure like test cuts can reveal. Relying solely on visible leaks is also not advisable, as they often indicate a more significant underlying issue that needs to be assessed thoroughly. Checking only the roof's surface condition neglects the importance of understanding what lies beneath, which is essential for an informed decision regarding recovery or replacement.
