International Compliance Association (ICA) Home Inspector Practice Exam

What structural deficiencies should home inspectors look for in roofs?

1. Only visible leaks

2. Uneven shingles and sagging areas

3. Presence of moss

4. Color changes in shingle material

The correct answer is: Uneven shingles and sagging areas

Home inspectors should focus on uneven shingles and sagging areas because these indicators can reveal underlying structural issues with the roof. Uneven shingles may suggest that the roof structure is compromised, which could stem from improper installation or damage to the decking beneath the shingles. Sagging areas often indicate that there is a significant problem with support, potentially due to advanced wear and tear, rot, or even water damage. While visible leaks are a critical concern and warrant attention, solely relying on their presence does not provide a comprehensive assessment of the roof's structural integrity. The presence of moss is more related to aesthetic concerns and may not directly indicate a structural deficiency, although it can signal areas where moisture retention occurs. Similarly, color changes in shingle material might indicate UV degradation or other cosmetic issues rather than severe structural problems. Therefore, examining signs like uneven shingles and sagging areas is vital for assessing the overall health and safety of a roof.
