Final answer:
A gap between the wall and soffit may indicate rafter sag or spread, which suggests that the integrity of the roof structure may be compromised. Moisture in the soffit and blocked gutters are separate issues that typically present different symptoms.
Step-by-step explanation:
If a gap exists between the wall and soffit, it may indicate rafter sag or spread. This problem, often stemming from structural issues, suggests that the rafters are not holding up the roof adequately, causing them to bend or move apart. This can lead to gaps where the soffit, which is designed to fit snugly against the house, no longer aligns properly.
It's important to address rafter sag or spread because it can compromise the integrity of the roof structure. Other signs that may accompany this include uneven rooflines or visible bending of the rafters. A professional should inspect and potentially repair any structural issues. Moisture in the soffit and blocked gutters can also cause problems, but these concerns would generally create different signs than a gap between the wall and soffit, such as soffit discoloration or overflow from the gutters.
