Post-Hurricane Impact Window Damage Inspection Guide

Florida's Florida Building Code requires that impact windows in High-Velocity Hurricane Zones (HVHZ) meet Miami-Dade Notice of Acceptance (NOA) standards before installation. HVHZ covers all of Miami-Dade and Broward County. That rigorous standard means your windows are designed to take a hit. However, even a window that passes a storm with its glass intact can lose critical performance properties. Seal failure, gasket compression damage, and hardware misalignment are all common outcomes of sustained wind-loading at 120+ mph. Insurance carriers in Florida treat these functional failures as legitimate hurricane damage. They fall under the windstorm portion of a homeowners policy, subject to your hurricane deductible — typically 2-5% of your home's insured value. Knowing that distinction matters before you pick up the phone to call your adjuster. A thorough impact window damage inspection, completed within 24-48 hours of the storm passing, gives you the strongest possible foundation for a successful claim.

3 distinct categories govern how post-storm impact window damage is classified. Each has a different repair or replacement path. Category 1 is cosmetic: surface scratches, minor paint scuffs on the frame, or small edge nicks in the aluminum. These do not affect the window's ability to open, close, lock, or perform under pressure. They are real damage but do not reduce your hurricane protection. Category 2 is functional: seal failure between insulated glass unit (IGU) panes, gasket deterioration, or hardware failure. The glass retains its impact rating, but the insulating value drops a lot once the IGU seal breaks. You'll see this as fogging or condensation between the 2 panes of glass. Category 3 is structural: visible cracking in the glass, delamination (the PVB or SGP interlayer separating from the glass layers), or missing panes. A window in Category 3 has lost its impact rating entirely and must be replaced — not repaired. To understand how these interlayers work, see our guide on laminated PVB impact glass.

Delamination is the most misunderstood outcome of a severe wind event, and missing it has serious safety consequences. Impact glass is manufactured as a laminated assembly: 2 or more layers of glass bonded to a polyvinyl butyral (PVB) or sentry glass plus (SGP) interlayer. That interlayer is what prevents the glass from shattering into dangerous fragments on impact. When a storm-pressure cycle causes the interlayer to separate from the glass, the window may look intact — no cracks, no visible holes — but it has lost its impact rating entirely. A subsequent wind event, even a minor one, can cause catastrophic failure. Delamination appears as a milky, bubbled, or wrinkled zone in the glass, usually starting at the edges and spreading inward. It is not repairable. The entire window unit must be replaced. To review your window's original performance ratings and whether a full replacement is required, check our impact window ratings guide for the technical specs. SafeGuard's crew checks for delamination on every post-storm walkthrough.

Florida homeowners insurance covers hurricane window damage under the windstorm portion of the policy. The process is more straightforward than most homeowners expect — IF you have your documentation in order. After completing your inspection, call your insurer's claims hotline within 24-72 hours of the storm. Most carriers have specific post-storm protocols and may schedule an adjuster visit within 3-7 business days. Have 4 things ready: your photo and video documentation, your original impact window installation records (including the NOA product approval numbers), your permit records, and any temporary repair receipts. Insurers can and do ask for NOA documentation to confirm the window met code at installation. This protects you from a denial based on "unapproved product." If you're unsure whether your windows qualify for a Citizens Insurance wind mitigation discount, that same NOA paperwork drives the credit. The hurricane deductible — typically 2-5% of insured value — applies separately from your standard deductible.

Not every storm-adjacent issue requires an emergency call. Cosmetic damage — frame scuffs, minor glass surface scratches — can be documented and reported to your insurer. Address cosmetic damage during a non-emergency service appointment. Functional damage like a fogged IGU is not urgent from a safety standpoint. The glass still provides impact protection. Schedule a professional inspection within 1-2 weeks and use that time to gather your claim documents. Structural damage — cracking, delamination, or missing panes — is a different matter entirely. Board up the opening immediately and call a licensed installer within 24 hours. Do NOT operate the damaged window under any circumstances. Even a minor edge chip can propagate under wind-load pressure. That can turn a Category 1 problem into a Category 3 failure. SafeGuard maintains a warranty callback rate below 3%. That means 97+ out of every 100 completed projects close out without a return visit. When storm damage does require a call-back, our licensed crew responds with documented repair or replacement specs. Your adjuster can use those specs directly. Homeowners throughout Miami-Dade and Broward County can reach us for post-storm inspections.

If your inspection reveals 1 or more windows needing full replacement, use the project as a chance to audit all your opening protection. Windows installed before 2002 may not meet current Florida Building Code requirements for HVHZ zones. Replacing storm-damaged units with a modern, high-performance product can improve your wind mitigation score. A better score can lower your annual insurance premium.
