Conducting a thorough evaluation of a roof assembly is crucial for identifying any underlying issues and determining the overall integrity of the roof. The requirement to remove all wet material before the evaluation is essential because moisture compromises the structural components of the roofing system. Wet materials can lead to further decay, mold growth, and can mask damage that might otherwise be visible.

By removing wet materials, inspectors can accurately assess the condition of the roofing system, including the decking and insulation. This clear view of the roof's condition allows for appropriate repairs or replacements to be identified. In a thorough roof evaluation, it is important for all elements that could obscure an accurate inspection to be removed, and wet materials are one of the most critical components in this context due to their potential for damage.

In contrast, while insulation, existing shingles, or ballast may also play a role in assessing a roof's condition, their removal is not as critical as that of wet materials, which can be actively causing damage and complicating the evaluation process. Removing wet material ensures that any necessary repairs can be executed based on a clear understanding of the structural integrity of the roof assembly.
