This page does not print an age threshold, because there is no single one. Underwriting rules are set carrier by carrier and filed state by state, and a number that was right for one company this year is wrong for another. What is general enough to be useful is what they look at, and what you can do about it.
Why the roof and not the rest of the house
Wind damage tends to start at an edge and work inwards. Once the covering or the deck goes, water follows, and a roof claim quickly becomes a contents and interior claim. That is why mitigation standards concentrate on how the deck is fastened and sealed and how the roof ties to the walls, and why a roof's age, material and condition carry more weight in a coastal file than almost anything else about the building.
What actually gets looked at
- Age and material. An architectural shingle roof and a metal roof of the same age are not the same risk. Typical Gulf Coast service lives are shorter than national averages because heat, humidity and UV do more work here, which is what the Borrowed Time Calculator is built on.
- Condition, from an inspection. Lifted, curled or missing shingles, exposed fasteners, failed flashing and soft decking. Some of this is visible from the ground with binoculars, which is a task on the maintenance calendar for exactly this reason.
- Documented mitigation. This is the part homeowners can change. Features that reduce the chance of the roof coming off can earn premium credits when they are documented by an inspection or a certificate, which has its own page here. An insurer prices what it can verify, not what is probably up there.
What to do before the renewal notice
- Find out how old it actually is. If the previous owner left you nothing, the county appraisal record and any permit history are the usual starting points, and a roofer can date a covering by looking at it.
- Get the wind mitigation inspection. In Florida the state program performs one free, which is on the My Safe Florida Home page, and the report is useful whether or not you take the grant. Elsewhere it is an inspection you pay for and it can pay for itself in credits.
- Ask your agent the direct question. "What does my carrier do with roof age, and what documentation would improve my position?" is a question an agent can answer in a phone call.
- If the roof is near the end anyway, look at the grant first. Four Gulf states put money toward rebuilding to a stronger standard, and doing it as a planned job rather than an emergency one is the difference between choosing a contractor and taking the one who knocked. The programs, state by state.
If you are non-renewed or cannot find cover
It happens on this coast and it is not automatically the end of the conversation. Shop the ordinary market through an agent first. If nobody will write it, every Gulf state has an insurer of last resort, which has its own page here. And your state insurance department takes questions and complaints for free:
- Mississippi Insurance Department
- Alabama Department of Insurance
- Louisiana Department of Insurance, consumers
- Florida Department of Financial Services, consumer services
- Texas Department of Insurance, consumer help
- The Borrowed Time Calculator · how much life your roof and three other systems likely have left, from one number.
- Wind mitigation discounts · the credits documented mitigation earns.
- Wind pools and insurers of last resort · what happens when the ordinary market says no.
