The answer to 'soffit curling' is that it is a common problem caused by a variety of factors, including poor ventilation, moisture buildup, and improper installation. Soffit curling occurs when the soffit material, typically made of vinyl or aluminum, begins to warp or bend away from the home's exterior.
One of the main causes of soffit curling is inadequate ventilation in the attic or roof space. This can lead to excessive heat and moisture buildup, which can cause the soffit material to expand and contract, leading to curling. Other factors, such as exposure to direct sunlight or extreme temperature changes, can also contribute to the problem.
