How long should a glaze coat be replaced with another coating?

The recommended timeframe to replace a glaze coat with another coating is typically five to ten years. This interval is determined by several factors, including the type of coating used, environmental conditions, and the wear and tear the surface experiences over time. A glaze coat, which serves to protect the underlying roofing material and improve its performance, can lose its effectiveness due to factors such as ultraviolet (UV) radiation exposure, water damage, and mechanical wear.

Replacing the glaze coat within this five to ten-year timeframe helps ensure that the roofing system continues to provide adequate protection and performance. The durability and longevity of the coating can vary, but regular maintenance and timely replacement of materials are crucial to maximizing the lifespan of the roofing system and preventing potential issues from arising due to an ineffective glaze coat.
