What does it mean to "prep" a roof surface before installation?

Preparing a roof surface before installation is crucial for ensuring the longevity and performance of the roofing system. This process typically involves cleaning the surface to remove any debris, dirt, or old roofing materials that could interfere with the adhesion of new materials. It may also include repairing any damaged areas, such as fixing leaks or replacing rotting wood, to create a stable and uniform base for the new roof. Proper surface preparation is essential as it allows for better adhesion of roofing materials, which directly impacts the overall effectiveness and durability of the installation. Without adequate preparation, issues such as water infiltration or premature failure of the roofing system can arise.
