Granule loss on roofing materials is significant because it can indicate potential moisture infiltration issues. The granules serve several purposes, including protecting the underlying layers of the roof from UV rays and preventing water infiltration. When granules are lost, it exposes the asphalt or fiberglass layers beneath, which can lead to deterioration and create pathways for moisture to penetrate the roof system. This increased vulnerability can result in leaks and further structural damage if not addressed in a timely manner.

While granule loss does also relate to aging and wear, its most immediate concern is the increased risk of moisture-related problems. Proper installation practices aim to minimize granule loss and ensure the roofing material performs effectively over its expected lifespan. Hence, understanding the implications of granule loss is crucial for assessing the overall condition and integrity of a roofing system.
