If you've ever stood in a big-box home improvement store staring at rows of shingles and underlayment, you already know how overwhelming roofing materials can be. Add Florida's strict building codes and a notoriously fragile homeowners insurance market into the mix, and the stakes get even higher. Choosing the wrong products — even if they look identical to the right ones — can cost you code compliance, insurance discounts, and, worst of all, your roof during the next big storm.
Understanding what "hurricane impact rated" actually means, and how to confirm a product qualifies, is one of the most practical things a Lakeland homeowner can do before any roofing project begins.
What Florida Product Approval Actually Means
Florida operates one of the most rigorous building product approval systems in the country, administered by the Florida Department of Business and Professional Regulation (DBPR) through its Florida Building Commission. The system is called Florida Product Approval, and it lives in an online database at the Florida Building Code website.
Before a roofing material — shingle, underlayment, metal panel, tile, or adhesive — can legally be installed on a Florida home, the manufacturer must submit it to an approved testing laboratory. That lab subjects the product to a battery of tests simulating real-world conditions: wind-driven rain, uplift pressure, impact from wind-borne debris, and long-term UV and moisture exposure.
If the product passes, it receives a Florida Product Approval Number (often formatted as FL#####). That number is the product's permission slip to be used on Florida roofs. Without it, no licensed contractor can legally install the material on a permitted job.
This system exists because Florida learned painful lessons from Hurricane Andrew in 1992, which exposed catastrophic failures in both construction practices and material standards. The result was a complete overhaul of the Florida Building Code, creating what is now one of the toughest sets of roofing requirements anywhere in the United States.
What "Impact Rated" Means for Roofing Materials
The term "impact rated" most commonly applies to windows, doors, and skylights — but roofing products also carry impact resistance ratings that matter enormously in Florida.
For roofing, the two most relevant performance standards are:
- TAS 100 and TAS 105 — Florida-specific test protocols that evaluate resistance to large-missile and small-missile impacts, simulating debris carried by hurricane-force winds.
- UL 2218 — An industry-standard impact resistance test that rates products Class 1 through Class 4, with Class 4 being the highest. Many Florida insurers specifically recognize Class 3 or Class 4 ratings for premium discounts.
- FM 4473 — Another widely recognized impact test used by some manufacturers as an alternative path.
A shingle or panel earns an impact rating by surviving repeated strikes from a steel ball (or standardized projectile) at defined velocities without cracking, splitting, or allowing water infiltration. Passing isn't just about surface appearance — the product has to remain watertight under the impact, because a roof that lets water in after debris hits it has failed its fundamental job.
It's worth noting that an impact rating and a Florida Product Approval number are related but not identical. A product can carry a FL# and still not be rated for the highest wind or impact zones. Always check both the approval status and the specific performance category listed in the approval.
How to Verify a Product Is Impact Rated
Homeowners don't have to take a contractor's word for it. Verification is straightforward:
1. Ask for the FL# number. Any reputable contractor should be able to provide the Florida Product Approval number for every major material they plan to use before the contract is signed.
2. Search the Florida Building Code Product Approval database. The public search tool (available at floridabuilding.org) lets you enter a product name, manufacturer, or FL# and see exactly what was tested, what conditions apply, and whether approval is current or expired.
3. Check the product packaging. Legitimate impact-rated materials will display test standard references (TAS 100, UL 2218 Class 4, etc.) directly on the packaging or in the manufacturer's spec sheet.
4. Request the Notice of Acceptance (NOA) for Miami-Dade. If you're in a High-Velocity Hurricane Zone (HVHZ) — which includes Miami-Dade and Broward counties — products must meet even stricter Miami-Dade County Product Control approval. An NOA is that approval document, and it's publicly searchable as well.
If a contractor can't produce these numbers or seems unfamiliar with the approval process, that's a meaningful red flag. Read more guides on our site for additional help evaluating contractor bids.
Why It Matters: Code Compliance and Real Insurance Savings
Installing non-approved or non-rated materials isn't just a technical violation — it has direct financial consequences.
Code compliance: Lakeland, like every Florida municipality, requires permitted roofing work to use products that carry valid Florida Product Approval. If an inspector discovers non-approved materials, the work can be rejected, requiring tear-off and reinstallation at the homeowner's expense. A failed inspection can also complicate a future home sale.
Insurance premiums: Florida's insurance market has been in crisis, with carriers leaving the state or dramatically raising rates. One of the levers homeowners actually control is the Florida Uniform Mitigation Verification Inspection form (OIR-B1-1802), commonly called the "wind mitigation inspection." When a licensed inspector documents that your roof uses qualifying impact-rated materials, your insurer must credit you for that in the form of a premium discount. Depending on your coverage, that discount can be substantial — sometimes hundreds of dollars per year — making the investment in better materials pay for itself over time.
Storm performance: Beyond paperwork, impact-rated products are simply built to take more punishment. During a storm damage event, a roof with tested, code-compliant materials is meaningfully more likely to stay intact and keep your home dry.
A roof replacement or even a roof repair is an opportunity to upgrade your home's protection. Our service areas page can confirm that Lakeland Roof Co serves Lakeland.
Don't Guess on Materials — Get a Pro Involved Early
The best time to discuss Florida Product Approval and impact ratings is before a single shingle is ordered, not after. A licensed local roofer familiar with Lakeland's specific wind zone requirements and insurance landscape will know exactly which products qualify, which earn the best insurance credits, and how to document everything for your wind mitigation inspection.
