Will Class 4 Shingles Lower My Insurance?

Will class 4 shingles lower my insurance? They can, but only if your insurer offers a credit for them and applies it to your policy. The credit is never automatic. Whether you get one depends on your insurer, your policy, and your home.

Florida law requires insurer rate filings to include certain credits for windstorm-reducing features, and roof covering is one of them. This guide explains how the impact rating works, what Florida rules say, and what to gather before you call your insurer. It is written for homeowners in Miami, Fort Lauderdale, West Palm Beach, Kendall, Boca Raton, Naples, and Fort Myers.

What Class 4 Impact Resistance Means

Class 4 is the highest impact rating in the UL 2218 test standard for roof coverings. The test drops a steel ball onto the shingle from a set height. A shingle rated Class 4 passed a harder version of that test than a lower-rated shingle. UL Solutions roofing testing describes how roof coverings are evaluated through recognized UL testing.

Think of the rating as a test result, not a promise. It shows how the shingle performed in a controlled test. It does not guarantee the roof will avoid damage in every storm.

Florida Statute § 553.8425 addresses demonstrating compliance with Florida Building Code windload requirements for local product approval. Under Fla. Stat. § 553.8425, products or systems of construction shall demonstrate compliance with the structural windload requirements of the Florida Building Code through one of the following methods, such as a commission-approved certification mark, test report, product-evaluation report, or statewide product approval. So ask for approval paperwork, not just a sales claim.

Can Class 4 Shingles Lower Your Homeowners Insurance?

Yes, they can, but only when the insurer offers the credit and applies it to your policy. Fla. Stat. § 627.0629 requires residential rate filings to include actuarially reasonable discounts, credits, or other rate differentials for properties with features shown to reduce windstorm loss. Roof covering performance is one of the listed features.

The statute also requires credits for features that meet the minimum requirements of the Florida Building Code. Those credits must be included in the rate filing itself.

A credit is not something you receive automatically at installation. You need to confirm it on your policy. Under Fla. Stat. § 627.711, an insurer issuing a personal lines residential property insurance policy must, using a form prescribed by the Office of Insurance Regulation, clearly notify the applicant or policyholder at issuance and at each renewal of the availability and range of each premium discount, credit, other rate differential, or reduction in deductibles, and combinations of these, for properties on which fixtures or construction techniques demonstrated to reduce the amount of loss in a windstorm can be or have been installed or implemented. Review your renewal paperwork closely.

Do Class 3 Shingles Save on Insurance?

Class 3 may qualify for a credit with some insurers, but the answer depends on the company. Class 3 is a lower impact rating than Class 4 on the same UL 2218 scale. Insurers set their rating rules within the framework Florida law sets. That means two classes can be treated differently.

Because each insurer sets its own criteria, the safe step is to ask. Ask which impact class qualifies for a credit on your specific policy. Ask whether the credit applies to the roof covering alone or depends on other features too.

Get the answer in writing. A written answer shows exactly which rating your insurer accepts. It also gives you something to compare at renewal.

Florida Wind Mitigation Credits and Your Roof

A wind mitigation credit is a discount tied to features that reduce windstorm loss. Your roof is one of those features, along with other parts of the home. Fla. Stat. § 627.0629 lists roof covering performance, roof strength, roof-to-wall strength, and window, door, and skylight strength among these features.

Many insurers rely on a standard inspection form. Under Fla. Stat. § 627.711, the Financial Services Commission develops a uniform mitigation verification inspection form. A home inspector licensed under s. 468.8314 who has completed at least 3 hours of hurricane mitigation training approved by the Construction Industry Licensing Board, and a proficiency exam, qualifies.

Inspections can cost money.

Ask your insurer whether a wind mitigation inspection could support a credit alongside an impact-rated roof. The answer tells you what documentation the insurer will need.

Documents to Gather Before You Call Your Insurer

Gather the product rating paperwork, the installation contract or invoice, permit records, and photos of the finished roof. These records show what was installed, when, and under what rating. Keep them together in one folder.

Florida generally requires a permit before work like this. Projects that change a building’s structure generally require a permit before work begins. Your permit record shows the work was done under that requirement.

For a single-family home, the roof replacement itself has required techniques. Under Fla. Stat. § 553.844, Florida Building Commission rules must address site-built, single-family homes in the wind-borne debris region that have an insured value of $300,000 or more (or, if uninsured or without documented insured value, a just valuation of $300,000 or more for ad valorem taxation). For these homes, a roof replacement must incorporate the techniques specified in subparagraph (2)(b)3., subject to the conditions and limits that the statute and those rules set out. Make sure your installation paperwork lists these items.

Write down the exact product name and rating too. Also record your policy number, the date of each call, and the name of the person who answered.

Assessing Your Roof After a Storm

Describe the roof in plain facts: the material, the impact rating, the installation date, and any damage you know about. Answer the question that was asked. Don’t guess about causes or timing you haven’t confirmed.

Deadlines matter after a storm. Fla. Stat. § 627.70132 says a claim or reopened claim (not a supplemental claim) is barred unless notice is given within 1 year after the date of loss. This time limit is tolled during a named insured servicemember’s deployment to a combat zone or combat support posting that materially affects their ability to file. A supplemental claim has an 18-month limit. For hurricanes, the date of loss is the date the hurricane made landfall; for other weather-related events, it is the date the National Oceanic and Atmospheric Administration verifies the event.

Ask for any decision or denial in writing. Keep copies of every letter, email, and photo. A clear paper trail makes each step easier to follow later.

What Class 4 Shingles Typically Cost

Cost depends on the product, roof size and pitch, tear-off needs, and permitting. Each home is different, so a single price rarely fits. Your estimate should reflect your own roof.

Weigh the added upfront cost against a possible insurance credit. Don’t assume the credit will cover the difference. Ask for an itemized written estimate that shows the standard-shingle price and the impact-rated price separately.
