How should inspectors evaluate roof decks?

When evaluating roof decks, looking for signs of failure is essential because it helps the inspector identify any existing or potential issues that could compromise the integrity of the roof structure. Signs of failure may include sagging, water stains, buckling, or any physical damage such as cracks or deformities in the decking material. These indicators not only suggest immediate problems but can also be indicative of other underlying issues, such as water intrusion or inadequate support.

Assessing the age of the roof, measuring the roof pitch, or inspecting the attic might provide useful information but do not directly assess the condition of the roof deck itself. The age might indicate potential wear but does not account for the current state. Roof pitch could influence drainage and potential leak issues but does not reflect the actual condition of the deck. Inspecting the attic can reveal signs of moisture or insulation issues but does not evaluate the decking directly. Therefore, focusing on signs of failure provides the most direct and relevant information regarding the current state of the roof deck.
