What does the term "tear-off" refer to in roofing terminology?

The term "tear-off" in roofing terminology specifically refers to the complete removal of existing roofing materials down to the deck before new roofing is applied. This process is essential for ensuring that the new roof is installed on a clean, solid surface, free from old materials that could retain moisture or cause other issues. A tear-off allows for a thorough inspection of the underlying structure, ensuring that any damages or weaknesses in the roof deck can be addressed prior to installation. This practice supports the longevity and effectiveness of the new roofing system, making it a critical procedure in roofing projects.
