Asphalt shingles are a cornerstone in residential roofing, offering a harmonious blend of durability, aesthetic appeal, and cost-effectiveness. Despite their robustness, they are not impervious to environmental challenges, particularly hail damage. Understanding the effects of hail on asphalt shingles is crucial for maintaining the integrity and longevity of your roof.

The Anatomy of an Asphalt Shingle

Granule Layer: The First Line of Defense

The granule layer, a bed of fine, rough particles, serves as the primary shield. It protects against UV rays and provides fire resistance.

Asphalt Layer: Waterproofing Core

Beneath the granules lies a dense asphalt layer, essential for the shingle’s waterproofing properties.

Reinforcement Mat: Structural Backbone

At the heart of the shingle is a reinforcement mat, typically made from fiberglass or organic materials, providing strength and stability.

Hail Damage: A Closer Look

Granule Loss: The Initial Blow

Hailstones can dislodge granules, leading to significant loss over time. This exposes the asphalt layer to UV rays, accelerating the aging process.
