What is a key requirement when replacing a roof with heavy tile?

When replacing a roof with heavy tile, it is crucial to check the structure support for the heavy tile load. Heavy tiles, such as clay or concrete, can significantly increase the weight that the existing roof structure must support. Before installation, it is essential to assess the load-bearing capacity of the roof framing and underlying materials to ensure they can safely handle the additional weight. Failing to reinforce the structure accordingly can lead to severe issues, including structural failure, which poses serious safety risks.

The importance of this requirement stems from building codes and safety regulations that dictate how different roofing materials should be supported. Proper evaluation of the existing framework helps prevent potential damage or collapse over time, ensuring that the building remains safe and functional following the roof replacement. This step is a fundamental part of responsible roofing practices and should not be overlooked.
