FORTIFIED Roof Replacement Project in Gretna, Louisiana
The available project record documents the construction scope and FORTIFIED evaluation path used for this Gretna home. It does not establish that Louisiana Fortify Homes Program funding was used on this project. FORTIFIED grants, Louisiana tax incentives, and homeowners insurance discounts are separate programs with their own eligibility, application, documentation, and approval requirements.
A FORTIFIED Roof can also be completed without a state grant. Homeowners should verify any expected financial benefit with the responsible agency, insurer, or tax authority before including it in a project budget.
The construction details below describe this specific Gretna project. They should not be treated as a universal specification for another home. IBHS states that projects permitted on or after November 1, 2025 must meet the 2025 FORTIFIED Home Standard. Where roof permits are not required, roofs installed on or after November 1, 2025 must meet the current standard.

This Gretna roof replacement was planned as a complete FORTIFIED Roof project rather than a shingle-only reroof. The documented scope included upgraded roof sheathing, enhanced deck attachment, a fully adhered secondary water-control layer, reinforced perimeter details, Atlas Pinnacle® Sun shingles, and independent FORTIFIED evaluation.
The project shows why homeowners comparing a conventional roof replacement with a FORTIFIED path should look beyond the finished shingles. Many of the critical differences are found in the deck, water-control layer, perimeter, fasteners, flashing, documentation, and construction-stage verification that become concealed as the roof is completed.
Project summary
What Was Installed on This Gretna Home
Beyond the finished shingles
Why This Was More Than a Standard Reroof
A finished asphalt-shingle roof can look similar from the street even when the construction underneath is very different. On a FORTIFIED project, many of the important details disappear from view as installation progresses.
That is why roof-deck attachment, secondary water protection, perimeter metal, starter material, flashing, roof-cover installation, and required construction photographs must be coordinated before those components are concealed.
For this Gretna home, the work did not stop with removal and replacement of the visible roof covering. The project addressed the roof deck, added a continuous secondary water-control layer, incorporated reinforced perimeter details, and coordinated construction with the independent evaluation process.
FORTIFIED is a construction and verification standard, not a shingle brand. Atlas Pinnacle® Sun was the selected roof covering for this project, but installing these shingles by themselves does not make a roof FORTIFIED.
Stage one
Strengthening the Roof Deck
The documented project scope called for new 15/32-inch sheathing over the home's existing 3/8-inch roof deck. The new sheathing was fastened into the rafters with 3-inch ring-shank framing nails at 4 inches on center.
The roof deck is the structural base beneath the water-control layer and finished roof covering. Ring-shank fasteners and enhanced attachment patterns can improve the connection between sheathing and framing compared with less robust fastening methods.
The exact roof-deck repair or fastening method for another home should not be copied from this project. It must be based on the existing construction, framing, deck condition, applicable building code, current FORTIFIED standard, and project-specific evaluator requirements.
Stage two
Secondary Water Protection and Stronger Roof Edges
After the deck work, a self-adhered ice-and-water membrane was installed across the roof surface as part of this project's documented assembly.
This secondary layer serves a different function from the finished shingles. If the primary roof covering is damaged or displaced during severe weather, a properly installed sealed-roof-deck assembly is intended to help reduce water passing through openings and joints in the roof deck.
The perimeter also received 26-gauge drip edge and adhered starter material. Roof edges are especially important because wind can act on vulnerable perimeter components and work beneath the roof covering when those details fail.
A sealed roof deck is designed to reduce water intrusion if the primary roof covering is compromised. It does not guarantee that water can never enter a home during severe weather and does not replace proper roof covering, flashing, drainage, vents, maintenance, or repairs.
Deck Attachment
The new sheathing was connected to the framing using the documented fastener type and spacing specified for this project.
Secondary Water Control
A fully adhered membrane was installed across the deck as the secondary water-control layer used on this roof.
Perimeter Details
Drip edge, starter material, fastening, membrane transitions, and perimeter details were coordinated as part of the roof assembly.
Construction Documentation
Critical details were recorded while they remained visible for the independent FORTIFIED evaluation process.
Stage three
Installing Atlas Pinnacle® Sun Shingles
Atlas Pinnacle® Sun architectural shingles were selected as the finished roof covering for this Gretna project.
Current Atlas product information identifies Pinnacle® Sun shingles as Class 3 impact resistant and lists 3M™ Cool Roofing Granules, Scotchgard™ Protector, and a 130-mph Wind Limited Warranty among the product features.
The wind figure is a manufacturer warranty term subject to Atlas installation and warranty requirements. It does not mean that the entire roof or home is guaranteed against damage in a storm producing winds at or below that speed.
Whole-roof performance depends on much more than the shingle product: roof-deck attachment, sealed-deck method, edges, starter, flashing, roof-mounted components, workmanship, roof geometry, surrounding exposure, and actual storm conditions all matter.
Construction and verification
FORTIFIED Requires Independent Evaluation
The roofing contractor performs the construction, but the roofing contractor does not independently issue the official FORTIFIED designation.
A certified FORTIFIED Evaluator documents applicable construction details and submits the required project information through the FORTIFIED process. This is especially important for components such as deck attachment and secondary water protection because those details can no longer be inspected once the completed roof covering conceals them.
Descriptions such as “high-wind roof,” “hurricane-ready,” or “built like FORTIFIED” should not be confused with an official FORTIFIED designation.
What a Written FORTIFIED Roof Scope Should Clarify
- Which current FORTIFIED standard applies to the project
- Who will serve as the independent certified FORTIFIED Evaluator
- Which evaluator costs are separate from the roofing contract
- How the existing deck and framing will be evaluated
- How concealed deck deterioration or repairs will be priced
- The required roof-deck attachment method
- The applicable sealed-roof-deck method
- Drip edge, starter, flashing, penetration, and roof-cover requirements
- Which construction stages must be photographed or inspected before they are concealed
- What happens if an existing condition prevents the planned designation requirements from being satisfied
Jefferson Parish conditions
Why the Complete Roof Assembly Matters in Gretna
Gretna and surrounding Jefferson Parish homes can experience long heat cycles, high humidity, intense rainfall, wind-driven rain, thunderstorms, and tropical-weather exposure.
Those conditions affect more than the visible shingles. Roof edges, deck joints, flashing, roof-to-wall transitions, vents, pipe penetrations, drainage paths, and other components can become water-entry or failure points when they are damaged, deteriorated, or poorly integrated.
A stronger roof does not make a home hurricane-proof, and no roofing system can guarantee that storm damage or water entry will never occur. The practical purpose of the FORTIFIED approach is to address multiple known roof vulnerabilities through a coordinated construction and verification process.
Financial programs are separate
Does This Gretna Project Prove Grant or Insurance Eligibility?
No. The construction record available for this page does not establish that the project received an LFHP grant, and this page does not make that claim.
LFHP is administered by the Louisiana Department of Insurance. FORTIFIED roofs can also be self-funded outside the grant program.
As of August 2026, LDI states that lottery registration is closed and that additional grant rounds will be announced later.
Current LFHP information →A FORTIFIED designation can affect insurance treatment in Louisiana, but the financial effect depends on the applicable designation, location, insurer, policy, and rating rules.
Louisiana Regulation 136 establishes benchmark discounts that must be implemented no later than January 1, 2027. The published benchmark percentages apply to the hurricane portion of the premium rather than automatically to the entire homeowners premium.

Homeowner questions
Questions About This Gretna FORTIFIED Roof Project
Was this project funded by a Louisiana Fortify Homes grant?
The available project record does not establish that LFHP grant funding was used, so this page does not make that claim. A FORTIFIED Roof can be self-funded, while LFHP participation requires a separate application and program process.
Does installing Atlas Pinnacle Sun shingles make a roof FORTIFIED?
No. Pinnacle® Sun is the roof-covering product used on this project. A FORTIFIED designation depends on the complete applicable roof system, construction details, documentation, independent evaluation, and FORTIFIED review process.
Does a 130-mph wind warranty mean this roof is hurricane-proof?
No. Atlas describes Pinnacle® Sun with a 130-mph Wind Limited Warranty, subject to its warranty and installation requirements. That figure is not a guarantee that the complete roof or home cannot sustain damage during a particular storm.
Why was new sheathing installed over the existing roof deck?
The documented scope for this home added 15/32-inch sheathing over the existing 3/8-inch deck. Another property may require a different deck repair, replacement, overlay, fastening, or engineering approach based on its condition and applicable requirements.
Can I copy the same FORTIFIED specification for my house?
No. This page documents one completed Gretna project. Current construction must be evaluated for the specific home and follow the FORTIFIED standard, building code, manufacturer requirements, evaluator findings, and other requirements that apply when the new project is performed.
Will a FORTIFIED Roof automatically lower my insurance premium?
No specific final premium should be assumed from the roof project alone. Louisiana has established FORTIFIED premium-discount benchmarks, but application depends on the designation, geographic zone, insurer, policy, and applicable rating rules. The benchmark percentages are applied to the hurricane portion of the premium.
Does a FORTIFIED Roof automatically qualify for an LFHP grant?
No. FORTIFIED is a construction and verification program. LFHP is a separate Louisiana grant program with its own eligibility, lottery, application, approval, evaluator, contractor, funding, and construction requirements.
Can the roofing contractor issue the FORTIFIED designation?
No. The roofing contractor completes the construction. A certified independent FORTIFIED Evaluator documents applicable work and submits the project through the FORTIFIED review process.
Project and program notice: This page documents a specific completed roofing project and was reviewed in August 2026 against current public information from IBHS, Atlas Roofing, and the Louisiana Department of Insurance. Construction requirements, product specifications, warranties, FORTIFIED standards, grant availability, and insurance rules can change. Project details shown here should not be treated as a universal specification or a guarantee of financial benefits for another property.
Planning a Roof Replacement in Gretna?
Southern Home Improvement Center can evaluate your existing roof and provide a written estimate for conventional roof replacement or a FORTIFIED roof path. If a grant, tax credit, or insurance discount is important to your decision, verify that program separately before authorizing work based on expected financial assistance.
