National Home Inspector Practice Exam

What should your report state if two adjacent manufactured roof trusses have had their webbing removed?

1. No problem exists since only two trusses have been modified, and they are adjacent

2. The trusses are no longer structurally sound, and the best method of correction should be determined by a qualified engineer

3. The trusses remain structurally sound, as the top chord and bottom chords have not been cut

4. The trusses have been compromised, and this area should be monitored for signs of future structural failure

The correct answer is: The trusses are no longer structurally sound, and the best method of correction should be determined by a qualified engineer

The report should state that the trusses are no longer structurally sound, and the best method of correction should be determined by a qualified engineer because the removal of webbing from manufactured roof trusses significantly compromises their structural integrity. Webbing plays a critical role in distributing loads and maintaining the stability of the trusses. When that webbing is removed, it can lead to a failure in the truss system under load, regardless of whether other components, like the top and bottom chords, remain intact. Only a qualified engineer can evaluate the situation and recommend the appropriate corrections or reinforcement strategies to ensure safety and compliance with building codes. This approach emphasizes the importance of consulting with professionals for potentially hazardous modifications to structural elements, thus prioritizing safety and addressing potential risks effectively.
