Solid tile roofs should be installed over solid sheathing.

The statement regarding solid tile roofs being installed over solid sheathing is considered false. Solid tile roofs, which are heavy and require a sturdy support system, are typically recommended to be installed over a framework that allows for proper drainage and ventilation. This often involves a system of purlins or battens rather than solid sheathing.

Using solid sheathing can trap moisture, leading to potential rot or other damage in the roof structure. Allowing for ventilation is crucial in maintaining the roof's integrity and longevity, especially with the weight and characteristics of tile roofing. Therefore, installing a solid tile roof over a ventilated structure ensures better performance, moisture management, and reduced risk of damage, validating that the correct answer is indeed false.
