When hail hits an asphalt shingle roof, three things happen:
- It breaks or cracks the shingle and exposes it to additional damage.
- It damages the asphalt.
- It loosens the granules that top the shingle for protection.
With the granules gone and the asphalt damaged, the shingles are vulnerable to additional damage from the sun’s ultraviolet (UV) rays. The damage might not be obvious after the storm, but your roof will eventually need replacement.
