What Causes Shingle Damage?

The most common causes of shingle damage in Palm Beach County include wind uplift from hurricanes and tropical storms, UV degradation from Florida's intense sunlight, hail and impact damage, algae and mold growth from humidity, improper installation, and poor attic ventilation. Understanding these causes helps Palm Beach County homeowners take preventative action and recognize when professional inspection and repair are needed.

Top Causes of Shingle Damage in Florida

• Wind Uplift: Hurricane and tropical storm winds can lift and remove shingles, especially older or improperly nailed shingles

• UV Degradation: Florida's intense sunlight breaks down asphalt shingle granules, causing rapid aging

• Algae and Mold Growth: High humidity promotes black streaking (Gloeocapsa magma algae) that damages granule coating

• Thermal Expansion: Extreme heat causes shingles to expand and contract, leading to cracking and blistering

• Poor Installation: Incorrect nail placement, insufficient fasteners, or improper underlayment reduce shingle performance

Frequently Asked Questions

Why do shingles fail faster in Florida than other states?

Florida's combination of intense UV radiation, extreme heat, high humidity, and hurricane-force winds puts far greater stress on shingles than climates in northern states. This is why impact-resistant, algae-resistant architectural shingles are the recommended choice for Palm Beach County.
