What Causes Shingle Damage?

The primary causes of shingle damage in Palm Beach County include UV radiation from Florida's intense sun (which breaks down asphalt binders and causes granule loss), hurricane and tropical storm wind uplift, impact damage from storm debris, algae and mold growth in the humid Florida climate, poor installation or improper nailing, and thermal cycling from daily heat expansion and contraction. Understanding what damages shingles helps Palm Beach County homeowners take protective action.

Common Causes of Shingle Damage in Florida

• UV radiation — Florida's sun is among the most intense in the US and accelerates granule loss and asphalt brittleness

• Hurricane and wind damage — Wind events lift, curl, and tear shingles from the roof

• Impact damage from storm debris — Flying branches and debris fracture shingles during storms

• Algae and mold growth — Breaks down shingle surfaces and holds moisture against the material

• Improper installation — Over-driven nails, under-nailing, or wrong nailing patterns compromise performance

• Poor ventilation — Excess attic heat accelerates shingle aging from the inside out

Frequently Asked Questions

What causes shingles to lose granules in Florida?

Granule loss is primarily caused by UV radiation, rain impact over time, and normal aging of the asphalt binder. Extensive granule loss is a sign the shingle is approaching the end of its serviceable life.
