What is the purpose of applying a glaze coat in roofing?

The purpose of applying a glaze coat in roofing is primarily to protect the roofing material. The glaze coat acts as a protective barrier that enhances the roofing system's longevity by shielding it from various environmental factors such as UV radiation, moisture, and temperature fluctuations. This protective layer helps to prevent deterioration that can occur due to exposure to the elements, ultimately prolonging the life of the roofing system.

While providing a smooth finish and potentially improving aesthetics can be secondary benefits of the glaze coat, they are not the primary purpose. The emphasis is on protecting the roofing material, ensuring it performs effectively over time and maintains its integrity against potential damage.
