Do Impact-Resistant Shingles Lower Your Insurance Costs?

They might, but nobody can promise it, and the answer depends on your insurer. Florida law pushes insurers to reward features that reduce windstorm losses. An impact resistant shingle is tested against hail, and that is a different thing from a wind rating.

This guide covers what the law says, how an impact resistant shingles insurance discount differs from wind mitigation credits, what to ask for in writing, and what to ask your insurer about class 4 shingles insurance. It is general information as of October 2026. No savings figures appear here, because we found no official Florida source that states one.

What Florida law says about discounts for roof features

The statute is section 627.0629 of the Florida Statutes (2026 edition). It states the Legislature’s intent: “It is the intent of the Legislature that insurers provide savings to consumers who install or implement windstorm damage mitigation techniques, alterations, or solutions to their properties to prevent windstorm losses.”

It also sets a rule for how insurers price. A residential rate filing “must include actuarially reasonable discounts, credits, or other rate differentials, or appropriate reductions in deductibles” for qualifying features. The list of features includes “wind uplift prevention, roof strength, roof covering performance.”

Notice what the statute is about. It is about windstorm loss. It does not mention hail, and it does not name any impact rating. It also doesn’t say how much any discount is, or that every insurer must offer one for a specific shingle. Those details sit in each insurer’s filed rates, which is why your agent has the final word.

How a roof-covering discount differs from wind mitigation credits

A wind mitigation credit rewards documented features. On Citizens’ discount page these include roof-deck attachment, roof-to-wall connection, roof shape, opening protection and roof covering. A hail rating answers a different question. It describes how a shingle handled a steel ball in a lab.

Citizens Property Insurance Corporation shows the gap on its public pages. We only reviewed Citizens, so other insurers may differ. Its discount page says its wind discounts “Apply only to the wind portion of your policy premium.” Under roof covering, it lists “FBC-equivalent asphalt shingles,” “FBC clay tiles” and “All other FBC-equivalent roof coverings.” FBC means the Florida Building Code. That list ties the roof-covering credit to code equivalence, and the page does not mention an impact class.

Citizens’ wind mitigation page is careful about outcomes. Documenting qualifying features “may save you money by helping you qualify for mitigation discounts on your insurance policy.” It says may, not will. The same page describes the covered feature as “Roofing materials and coverings that are rated to resist high winds and water intrusion.” The discount page also tells you where to start: “Speak with your agent to see if you qualify or what you need to do to qualify.”

The takeaway: a Class 4 label does not automatically earn a wind credit, and on Citizens’ list a roof-covering credit does not mention one. For what the Class 4 rating actually measures, see our explainer on class 4 impact resistant shingles.

Hail resistant shingles, coverage and deductibles

Hail resistant shingles are shingles tested for hail impact, for example under UL 2218. The IBHS Fortified program describes Class 4 as meaning “the product was still functional after being struck twice in the same spot by 2-in. steel balls.” That is a product test. It says nothing about what your policy covers.

Your policy decides how a hail loss is handled. Florida defines hurricane coverage narrowly: Section 627.4025 says “Hurricane coverage” is “coverage for loss or damage caused by the peril of windstorm during a hurricane.” A hail loss from an ordinary thunderstorm may therefore fall under a different deductible than a hurricane loss. Whether your policy uses a separate wind or hail deductible, a flat dollar deductible or a percentage varies by insurer and policy.

Look at your declarations page, the summary page of your policy. Find the line for deductibles, and ask your agent in plain words: “If hail damages my roof, which deductible applies?” For what hail does to a roof and the steps after a storm, our guide to hail damage to your roof covers it.

Don’t pay extra on a promised discount

A contractor, a manufacturer’s brochure or a neighbor may tell you an impact-rated roof will cut your premium. Treat that as a question, not a fact. The only party that can confirm a discount is your insurer, and the safest proof is a written answer from your agent before you order materials.

If the answer is “no discount,” you can still choose a tougher shingle for other reasons, such as the hail protection it was tested for. Just make that choice with the right expectation, and get the extra cost itemized in your quote so you know what you are paying for.

What documentation to ask for

If you install an impact-rated roof and want your insurer to consider it, paperwork is what turns a good roof into something an underwriter can rate. Citizens says “Documentation is required before any discounts are applied, and the cost of any required certification of discount-eligible features is the homeowner’s responsibility.” Other insurers set their own rules, so ask which they accept.

Ask your roofer for these, and keep copies:

• The product data sheet. It should show the UL 2218 class (or other test) for the exact shingle installed, plus its wind rating.
• The invoice or contract. It should name the product and the scope, so the roof covering is described the way the data sheet describes it.
• The building permit. Ask your roofer whether your address needs one and who pulls it, since the rules vary by county or city.
• Dated photos. Photos of the roof as it goes on, including the underlayment, show what was installed under the shingles.
• An inspection report or form. If your insurer wants a wind mitigation inspection or a roof inspection, ask which form and who may sign it.

A roofer can supply the first four. The fifth depends on your insurer’s requirements. None of it guarantees a discount.

Questions to ask your insurer or agent about class 4 shingles insurance

Call before you buy. A five-minute call can save you from paying extra for a feature your insurer doesn’t price.

1. Do you offer a discount or credit for an impact-rated roof covering, and for which classes or tests?
2. Is it a hail credit, a wind credit, or both, and does it change the wind part of my premium?
3. What documents do you need, and in what form?
4. Do I need a wind mitigation inspection or roof inspection, and who is allowed to sign it?
5. Which deductible applies to a hail loss, and how is it calculated?
6. Does my policy pay replacement cost or actual cash value for the roof?
7. If I install the roof and send the paperwork, when would any change show up?

Write down the answers, with the date and the person’s name.

Questions homeowners ask about impact resistant shingles and insurance

Do impact resistant shingles lower insurance costs in Florida?
Sometimes, depending on the insurer. Florida law directs insurers to include discounts for windstorm-loss features in rate filings, but it doesn’t promise any amount for hail ratings. Ask your insurer which credits apply to your roof.

Is an impact resistant shingles insurance discount the same as a wind mitigation credit?
No. A wind mitigation credit is based on documented wind features. An impact class is a hail test result. Your insurer may price one, both or neither.

What documents do I need for a roof discount?
It varies. Expect to be asked for the product data sheet, invoice, permit, photos and possibly an inspection form. Citizens, for one, says documentation is required before it applies any discount.

Can my roofer get me an insurance discount?
No. A roofer can give you the product data sheet, invoice and photos. Whether a discount applies is your insurer’s decision, so ask your agent.

Will my deductible change with a Class 4 roof?
Not automatically. Your deductible is set by your policy, and your insurer decides whether a roof feature affects it. Ask your agent.
