Which of the following can cause ridge issues?

Overloaded roof surfaces can indeed lead to ridge issues, as they place undue stress on the structure of the roof, particularly at the ridgeline. When too much weight accumulates—whether from snow, ice, or even excessive layers of roofing material—it can cause the ridge to sag or deform. This distortion not only compromises the integrity of the roof but can lead to issues such as leaks, poor drainage, and even structural failure if not addressed.

In contrast, a proper roof design ensures that loads are distributed evenly and that the roof can bear the weight without leading to problems at the ridge. Similarly, a well-maintained ridge beam will support the structure effectively, resisting any potential sagging or shifting. Regular inspections are crucial in identifying any signs of distress or potential overloads before they escalate into significant issues, but they do not directly contribute to ridge problems in themselves. Thus, while the other choices emphasize positive aspects of roofing, it is the overload on the roof surface that can directly cause ridge issues.
