How Long Does Soffit Last?
Lifespan by Material

National lifespan estimates for soffit are based on moderate-climate data. Florida's conditions are significantly more aggressive:

• HumidityYear-round high humidity accelerates wood rot and corrodes fasteners. Aluminum and vinyl are not affected by humidity, but the wood nailer boards behind them can still rot, which eventually causes the soffit panels to fail.
• UV RadiationFlorida receives some of the highest UV index readings in the continental US. UV degrades vinyl faster than aluminum — south and west-facing vinyl can become brittle 3–5 years earlier than national averages suggest.
• Hurricane SeasonAnnual wind events (and the major storms every few years) physically damage soffit panels, bend fascia, and create gaps that allow water and pest intrusion. A Category 1 pass can take years off any soffit's life.
• WildlifeCentral Florida has an active wildlife population: raccoons, squirrels, roof rats, and bats all actively look for soffit gaps. A small opening becomes a large one quickly once an animal starts working it.
