What Causes Shingle Damage?

Shingle damage in Palm Beach County, Florida is caused by a combination of environmental and installation factors. The most common causes include intense UV radiation that degrades granule coating, hurricane and high-wind events that lift or tear off shingles, hail impact, algae and mold growth in the humid Florida climate, thermal expansion and contraction cycling, and improper original installation. Understanding these causes helps homeowners take preventive action and identify damage early.

Common Causes of Shingle Damage

• UV Degradation: Florida's intense sun breaks down the asphalt binder and dislodges protective granules, leading to cracking and brittleness

• Wind Damage: Hurricane-force winds and tropical storms can lift, crack, or completely remove shingles

• Hail Impact: Hail strikes create impact marks that dislodge granules and compromise shingle integrity

• Algae and Mold: Biological growth causes dark streaking, retains moisture, and can degrade shingle materials

• Thermal Cycling: Daily temperature fluctuations cause shingles to expand and contract repeatedly, leading to cracking and curling over time
