What does the term "counter batten" refer to in roofing?

The term "counter batten" refers specifically to a vertical installation that is used to secure horizontal patterns. In roofing, counter battens are typically placed over existing battens to create a grid system that allows for improved ventilation and drainage beneath the roofing materials. This installation technique helps ensure the durability of the roof and can also help in reducing moisture buildup, which is critical for avoiding roof damage.

This method is particularly beneficial in certain roofing applications, where airflow needs to be managed carefully to prolong the life of the roofing system and enhance energy efficiency. Counter battens provide structural support for the roofing layers, creating a more robust and reliable installation overall.
