What Causes Shingle Damage?

The most common causes of shingle damage in Palm Beach County are hurricane and tropical storm winds, UV radiation degradation, poor attic ventilation that causes heat buildup, algae and mold growth accelerated by Florida's humidity, improper installation by unlicensed contractors, and normal aging. Understanding these causes helps homeowners take proactive steps to extend their shingle roof's lifespan.

Top Causes of Shingle Damage in Palm Beach County

• Hurricane and Tropical Storm Winds — High winds lift, tear, and remove shingles. Shingles with insufficient wind rating (3-tab shingles) are particularly vulnerable.

• UV Degradation — Florida's intense year-round solar radiation breaks down the asphalt binder in shingles, causing granule loss and brittleness.

• Poor Attic Ventilation — Attic temperatures of 150-180°F are common in Florida without proper ventilation. This extreme heat cooks the adhesive strips on shingles, causing them to buckle or delaminate.

• Algae and Mold Growth — Black streaks and mold on shingle surfaces indicate biological growth that can retain moisture and accelerate shingle breakdown.

• Improper Installation — Incorrectly driven nails, wrong nail placement, or insufficient nail quantity reduces wind resistance and accelerates failure.

• Foot Traffic — Walking on a shingle roof without proper care can crack or dislodge shingles.

Frequently Asked Questions

How do I know if wind has damaged my shingles?

After a storm, look for missing shingles, exposed decking, uplifted shingle edges, and shingles with loosened adhesive strips. However, many forms of wind damage are not visible from ground level and require a professional inspection.
