Why this is happening to so many Florida homeowners
It is not your roof. It is the Florida insurance market.
For most of the last decade, Florida's property insurance market took a beating. Carriers paid out heavily on storm claims, then watched the cost of reinsurance, the insurance that insurers buy to cover their own catastrophe risk, climb sharply. On top of that, the state saw a wave of roofing-related claims and litigation, much of it driven by aggressive solicitation and assignment-of-benefits abuse. Several carriers went insolvent. The ones that survived got strict, and a lot of them got strict about the same thing: the age of your roof.
Here is why age became the lever. A roof is the single most expensive part of a home to replace, and it is also the part most likely to fail in a hurricane or a wind event. From an underwriter's desk, an older shingle roof is a bet they would rather not take. So instead of inspecting each roof one by one, many carriers wrote age caps straight into their underwriting rules. The common ones you will run into on the Gulf Coast: shingle roofs older than roughly 15 to 20 years get non-renewed or refused, while tile and metal roofs, which last longer, get more runway, often into the 25 to 40 year range depending on the carrier. The key thing to understand is that these caps are frequently applied by age alone, regardless of how good your roof looks. A perfectly sound 17-year-old shingle roof can get a non-renewal letter while the shingles still have plenty of grit on them.
That is the part that stings. You did nothing wrong. The roof is doing its job. But the carrier is making a portfolio decision, not a judgment about your specific house. Knowing that changes how you respond, because the right move is not to argue that your roof is fine. The right move is to use the tools the state gives you to either prove the roof has useful life left, or to reset the clock with a new roof on your own timeline instead of theirs.
