Your renewal just jumped. Here is what actually causes it.

Florida homeowners insurance rates dropped in 51 of the state's 67 counties this year. Citizens approved an average statewide decrease of 8.7%. Private carriers have been filing reductions too.

So when a renewal notice arrives with a higher number on it, the natural reaction is that something has gone wrong. Usually something specific has, and it is worth working out what before you accept it.

1. Your roof crossed an age threshold

This is the most common cause by a distance.

Most Florida carriers price roofs in bands, and the bands matter enormously. A shingle roof at nine years is priced very differently from the same roof at eleven. Some carriers will not write a shingle roof over fifteen years at all; others will, but at a rate that reflects the risk.

Nothing about your house changed. The roof simply got a year older and crossed a line in the carrier's rating.

What to do: if your roof is newer than the carrier thinks, tell them. Roof replacement dates get recorded wrongly more often than you would expect, particularly after a change of ownership. And if the roof genuinely is ageing, other carriers draw the line in different places — it is worth finding out where.

2. The carrier reinspected and did not like what it found

Carriers periodically send an inspector round, or use aerial imagery. If they find something they consider a hazard, the rate moves or conditions get added.

Common findings: a tree overhanging the roof, missing shingles, a fence in poor repair, an unfenced pool, debris in the garden, or evidence of a leak.

What to do: ask for the inspection report. You are entitled to see what they found. A surprising number of these are fixable within a few weeks, and carriers will often reconsider once you send photographs of the work.

3. The rate decrease genuinely did not reach you

Statewide averages are exactly that — averages. Individual carriers file their own rates, and they take effect at renewal rather than on a fixed date.

So if your carrier has not filed a decrease, or filed one that takes effect after your renewal date, you will not see it. Someone renewing in April and someone renewing in August with the same carrier can have very different experiences.

What to do: this is the case where shopping helps most. The decrease is real, it is just uneven — and a carrier who filed a reduction is out there even if yours did not.

4. Something changed that you did not think mattered

A claim, even a small one. A lapse in coverage, even briefly. A change in the dwelling coverage amount as building costs are recalculated. Adding a pool, a trampoline, or a dog of a breed the carrier will not accept.

Some of these are worth arguing. Others are simply the new reality and the question becomes whether another carrier prices them differently.

What not to do

Do not just pay it. A renewal notice is a proposal, not a bill you are obliged to accept. You can move carriers at any point, and a mid-term cancellation is prorated.

Do not reduce your coverage to hit a number. Raising a deductible is a legitimate choice made deliberately. Quietly cutting your dwelling coverage below what it would cost to rebuild is a problem you will only discover after a claim.

And do not assume your agent has already shopped it. Some do automatically. Many do not, particularly if they only represent one or two carriers.

The order worth working through

Get the declarations page and compare it line by line against last year's. Find what actually changed — often it is one field.

Ask your agent to explain the increase specifically. "The market went up" is not an explanation.

Check whether you have wind mitigation credits applied. If not, that inspection may be worth more than anything else on this list.

Then get quotes from carriers your current agent does not represent. That is the part most people skip, and it is where the difference usually is.
