The one rule that decides everything
Insurance covers sudden and accidental, not slow and expected.
Every standard homeowners policy in Florida is built on one idea: it pays for damage that happens suddenly, by accident, from a specific event the policy lists. Insurers call those listed events "covered perils." A windstorm that lifts shingles on a Tuesday afternoon is sudden and accidental. A tree limb that crashes through the deck during a hurricane is sudden and accidental. A roof that slowly dried out, curled, and lost its granules over fifteen Florida summers is neither. It is expected. The sun was always going to do that, and the policy was never meant to pay for the ordinary aging of your house.
That single distinction is why two roofs with similar-looking damage get opposite answers from the same insurer. The question your adjuster is really asking is not "is this roof damaged?" It is "what caused this, and when?" If the answer is a covered peril on a datable day, the claim has a path. If the answer is time, heat, and neglect, it does not, no matter how bad the roof looks. Most claim fights, and most of the frustration homeowners feel, come down to a disagreement about that one question of cause.
So before you file, it helps to understand both columns: the events that count as covered perils, and the conditions that insurers treat as your responsibility to maintain. Below is the plain-English version of each, written for a Florida Gulf Coast roof that lives under brutal UV, summer storms, and the threat of a named system every hurricane season.
