Which two basic elements must be inspected during a roof inspection?

During a roof inspection, it's crucial to assess the weather-resistant covering and sheathing because these elements play essential roles in the overall integrity and functionality of the roofing system.

The weather-resistant covering, often roofing shingles or other materials, protects the structure from water infiltration, which can lead to significant damage over time. This covering also deflects UV radiation and resists other weather-related threats.

Sheathing, typically made of plywood or oriented strand board (OSB), is the structural foundation on which the roofing materials are installed. It provides support and rigidity to the roof and is critical for a secure installation of the weather-resistant covering.

By inspecting both the weather-resistant covering and the sheathing, home inspectors can evaluate not only the immediate performance of the roof in preventing leaks and structural issues but also determine the long-term durability and potential need for repairs or replacements. Understanding these components allows inspectors to provide a thorough assessment of the roof's condition.
