Retro-FORTIFIED™ Spray Foam Roof Upgrade Now Available in Louisiana & Mississippi
Homeowners across hurricane-prone Louisiana and Mississippi are facing higher risks — and higher costs — as Gulf Coast weather becomes more intense. Stronger wind events, wind-driven rain, and repeated storm seasons make roof resilience more important than ever. A Retro-FORTIFIED™ spray foam roof upgrade gives homeowners a practical way to improve protection and potentially qualify for meaningful wind mitigation savings, without the disruption or expense of a full tear-off.
This retrofit approach focuses on what matters most during hurricanes: keeping the roof deck sealed, reducing uplift risk, and improving overall roof system performance. If your roof is in good condition and your attic is accessible, this upgrade may be one of the fastest paths to a stronger roof deck and verified documentation.
Why a Retro-FORTIFIED™ Closed Cell Spray Foam Retrofit Can Beat Full Replacement
In Southeast Louisiana and Coastal Mississippi, the roof is your home’s first line of defense. Full roof replacements can be effective — but they are also costly, time-intensive, and not always necessary when the existing roof cover is still in good shape. That’s why more homeowners are exploring a sealed roof deck retrofit using closed cell spray foam as a non-invasive way to strengthen performance where it counts.
Instead of removing shingles, this system reinforces the underside of the roof deck by sealing panel seams and strengthening critical connections. The result is a sealed roof deck that supports wind resistance goals aligned with IBHS FORTIFIED™ technical requirements — with no tear-off and no structural redesign.
Cost-Effective Upgrade for Existing Roofs
Installing a brand-new FORTIFIED™ roof system can cost thousands more than a retrofit. By comparison, a spray foam roof deck retrofit for a roof that is less than five years old often costs roughly half as much — and in some cases even less — while still delivering measurable protection improvements. Many homeowners see the strongest value when the existing roof cover is still serviceable but they want enhanced hurricane performance.
Fast Installation, Minimal Disruption
While a full roof replacement may take multiple days, most Retro-FORTIFIED™ spray foam upgrades can be completed in as little as one day, depending on attic access and preparation requirements. There is no need to remove shingles or panels — only attic access is required. This can reduce labor, simplify scheduling, and minimize disruption to daily life.
Flexible and Non-Invasive by Design
This upgrade is designed for homeowners who want better hurricane resistance without a full exterior tear-off. In practice, it’s a cleaner job site and a simpler project path for many occupied homes:
- No tear-off debris — landscaping, gutters, and solar equipment remain undisturbed
- Compatible with many common roof cover types
- No structural modifications required, which can simplify permitting in many parishes and municipalities
When the roof cover is still in good condition, a retrofit approach can be the most efficient way to strengthen the deck without restarting the entire system.
Insurance Discounts and Wind Mitigation Eligibility
A certified sealed roof deck retrofit may qualify for windstorm insurance discounts of up to 55%, depending on your provider, your location, and your policy structure. Savings vary by carrier and underwriting requirements. Eligibility can also depend on how documentation is submitted and verified.
Incentives and programs differ by state and change over time. If you are evaluating this upgrade based on insurance or potential incentives, we recommend confirming details directly with a licensed insurance agent familiar with wind mitigation credits in your area.
Delivered by Certified Experts Across Louisiana and Mississippi
Southern Home Improvement Center (SHIC) provides this next-generation retrofit across the Gulf Coast, helping homeowners strengthen what they already have — without starting from scratch. Our focus is simple: evaluate the roof, seal the deck correctly, document the work, and help homeowners get verified results.
How the Retro-FORTIFIED™ Spray Foam Roof Upgrade Works
Although the system is technically advanced, the upgrade process is designed to be efficient, clean, and consistent. Every step is completed by trained professionals and verified through documentation.
1) Certified Evaluation
A licensed FORTIFIED™ Evaluator assesses attic conditions and roof deck integrity. To qualify, the roof should be in good condition, free of active leaks, and typically less than five years old. Many post-storm roof replacements may qualify, provided the roof system and local code requirements support certification eligibility.
2) Preparation & Access
Technicians prepare the attic, protect work areas, and ensure clear access to the roof decking. In some cases, insulation or HVAC components may be temporarily relocated to create a clean application path.
3) Closed Cell Spray Foam Application
Closed cell polyurethane foam is applied to decking seams, intersections, rafters, and key transition zones — forming a continuous sealed surface that helps resist water intrusion and uplift forces.
4) Documentation & Certification
Work steps are documented by the evaluator and submitted for review. Once approved, the homeowner receives an official FORTIFIED™ Roof Certificate confirming the retrofit upgrade documentation.
5) Insurance Notification
The certificate can be submitted to your insurer for consideration at renewal or policy update. Discount application and timing depend on the provider.
Engineered to Perform in Hurricane Conditions
The Retro-FORTIFIED™ sealed roof deck retrofit follows technical requirements intended for reliable performance in high-wind regions. The purpose is not comfort insulation — it is roof deck sealing and structural reinforcement aimed at storm survival and reduced water intrusion.
Spray Foam Specifications
To support a sealed deck retrofit, the material and application must meet strict criteria. Typical specifications include:
- Type: Two-component closed cell polyurethane
- Density: 1.5 – 3.0 pcf (per ASTM D1622)
- Application: From within the attic (not applied on top of the roof)
- Coverage: Continuous foam applied to panel seams, intersections, and valleys
This approach is designed to create a continuous sealed surface where roof decks typically fail during wind-driven rain and pressure cycling.
Wind Resistance Testing
Performance testing for sealed roof deck systems is commonly tied to recognized standards. Testing may reference protocols such as ASTM E330 and TAS 202-94, with performance targets varying by zone classification:
- Hurricane zones — must resist 110 psf (often tested to 165 psf or more)
- High-wind zones — must resist 80 psf (often tested to at least 120 psf)
Structural Reinforcement Benefits
Beyond sealing out water, closed cell foam increases bond strength between roof decking and framing. This reinforcement can significantly reduce the risk of roof deck blow-off or progressive failure during major wind events.
Who’s a Good Fit for This Retrofit?
Not every roof needs full replacement to improve hurricane performance. Your home may be a strong candidate for this retrofit if the roof structure is sound and the attic allows proper access. Most qualified homes fit the following profile:
- The roof is in good condition with no major leaks or widespread damage
- The roof is typically less than 5 years old
- The attic is accessible and the roof deck can be reached safely
- You live in hurricane-prone areas of Louisiana or Mississippi
- You want verified roof deck sealing with potential wind mitigation benefits
A certified evaluator can confirm eligibility and explain the best path based on your roof’s condition, local requirements, and documentation goals.
