What Is A Fortified Roof?
A fortified roof is a roofing system built using strict standards to resist severe weather. These standards are set by the Insurance Institute for Business & Home Safety (IBHS), an organization dedicated to improving the resilience of homes and businesses. The core idea behind a fortified roof is to provide substantially higher resistance to wind, rain, and hail than typical code-minimum roofing systems. By enhancing the roof’s strength and water resistance, homeowners gain powerful protection against storm damage.
Key Components Of A Fortified Roof
The effectiveness of a fortified roof lies in its carefully engineered components. Each element is chosen or installed to strengthen the entire roofing system against threats from nature. Four primary features define a roof as “fortified.”
Sealed Roof Deck
A sealed roof deck helps prevent water from entering the home even if shingles or other outer materials are blown off. Specialized tape or a membrane is used to seal the seams between roof decking panels. This crucial step significantly cuts the risk of water intrusion during a storm.
Enhanced Roof Deck Attachment
The roof deck is fastened with improved nails (ring-shank nails recommended) rather than basic staples or smooth nails. This upgraded attachment method increases the deck’s resistance to being peeled away by strong winds.
Impact-Resistant Coverings And Shingles
Fortified roofs often use shingles or other coverings that are rated for high-impact resistance. These materials can withstand wind-driven hail and flying debris, protecting the home’s interior from expensive water and structural damage.

Better Roof-To-Wall Connections
For higher levels of FORTIFIED certification, roof-to-wall connections are critical. Metal connectors or hurricane ties create a continuous load path from the roof to the walls, helping the structure resist “uplift” during wind events.
FORTIFIED Roof™ Program: Certification Levels
The IBHS FORTIFIED™ program offers three escalating levels of certification, letting homeowners choose the right degree of protection. Each level has strict requirements and must be validated by a certified evaluator.
- FORTIFIED Roof™ – Focuses solely on strengthening the roof system itself, like sealed roof deck and better roof fasteners.
- FORTIFIED Silver™ – Includes all roof upgrades plus enhanced protection for openings such as windows and doors, and verified roof-to-wall connections.
- FORTIFIED Gold™ – Highest level: adds load path continuity to keep the entire building system intact during extreme weather events.
Many homeowners insurance companies offer discounts for verified FORTIFIED certifications due to the proven reduction in losses after storms.
How A Fortified Roof Protects Your Home
The core purpose of a fortified roof is providing superior wind and water protection in hurricanes, tornadoes, and severe thunderstorms. The system is designed so that, even if the roof’s shingles or tiles are compromised, the underlying deck remains sealed and attached, preventing catastrophic water intrusion and interior damage.
During powerful storms, a sealed and well-fastened roof deck resists pressure from upward winds that can “peel off” standard roofs. Impact-resistant materials shield against hail, and improved flashing techniques stop water from seeping into vulnerable roof valleys and edges. This comprehensive approach dramatically reduces the chance of costly roof failure.
Standards And Testing For Fortified Roofs
FORTIFIED Roof standards are influenced by decades of research and real-world post-storm investigations by IBHS and other authorities. Roofs are tested for resistance to:

- High winds (up to 130-150 mph, depending on certification level)
- Wind-driven rain
- Impact from hail up to 2 inches in diameter
- Flying debris
Certification requires third-party verification. Homeowners must work with a FORTIFIED Evaluator, who inspects the installation and documents each step with photos and reports.
Benefits Of A Fortified Roof For Homeowners
Choosing a fortified roof is an investment in safety, resilience, and peace of mind. Here are key advantages:
- Reduced storm damage and losses: Studies show homes with fortified roofs suffer significantly less damage compared to standard roofs in hurricanes and other disasters.
- Insurance discounts: Many insurers offer savings on premiums for homes certified as FORTIFIED.
- Greater home resale value: The added protection is attractive to buyers, especially in storm-prone areas.
- Lower repair and maintenance costs: Enhanced materials and construction mean fewer leaks, less mold growth, and less roof deterioration over time.
- Peace of mind: Homeowners can feel confident that their property is ready for the next big storm.
Who Needs A Fortified Roof?
A fortified roof is ideal for anyone living in regions vulnerable to hurricanes, tornadoes, or severe hailstorms, including:
- Gulf Coast states (Texas, Louisiana, Mississippi, Alabama, Florida)
- Atlantic coastal areas (Carolinas, Georgia, Virginia)
- Midwestern “Tornado Alley” (Oklahoma, Kansas, Nebraska, Iowa)
- Parts of the Rocky Mountains and Great Plains affected by severe hail
For new homes, major renovations, or roof replacements, upgrading to a fortified system provides lasting protection and value.
How To Get A Fortified Roof: Step-By-Step Guide
Securing a FORTIFIED roof requires working with trained professionals and adhering to the IBHS guidelines. Here is a typical process:
1. Consult With A FORTIFIED Contractor
Find a roofing contractor certified or experienced with FORTIFIED Roof installations. IBHS maintains a national database to help homeowners connect with qualified professionals.
2. Hire A FORTIFIED Evaluator
An independent evaluator ensures that every aspect of the roof—materials, installation, sealing—is completed to standard. The evaluator documents with photos, checklists, and reports for insurance and certification purposes.
3. Select The Right Certification Level
Choose between FORTIFIED Roof, Silver, or Gold—based on your risk, budget, and desired level of protection.
4. Begin The Roof Replacement Or Upgrade
Specific steps include:
- Old roofing removed down to deck (plywood or OSB)
- Deck inspected, repaired, and possibly re-nailed with ring-shank nails
- Sealing applied to all seams—special tape or spray membrane
- Flashing installed around valleys, edges, and penetrations
- Impact-rated shingles or approved coverings installed
- Attic ventilation and insulation checked and improved as needed
This process ensures all elements work together as a system—no “weak links.”
5. Final Inspection And Certification
Once installation is complete, the evaluator conducts a thorough inspection. If all standards are met, a FORTIFIED certificate is issued—the key to insurance discounts and proof of protection.
Cost Of Fortified Roofs: Investment And Savings
The initial cost of a fortified roof is typically 10-30% higher than a conventional roof replacement. This premium reflects better fasteners, sealing materials, enhanced underlayment, and certified labor.
On a $10,000 shingle roof, expect to pay $1,000–$3,000 more for FORTIFIED compliance. However, insurance premium reductions (often 5–30%) and reduced storm damage offer excellent return on investment.
| Roof Type | Standard Roof Cost | FORTIFIED Roof Cost | Est. Insurance Premium Savings |
|---|---|---|---|
| Asphalt Shingle | $8,000–$12,000 | $9,000–$15,600 | 5–30% yearly |
| Metal | $12,000–$25,000 | $14,000–$30,000 | 5–20% yearly |
Repairs, insurance deductibles, and loss of home use following a storm can far surpass the upfront expense of FORTIFIED upgrades.
FORTIFIED Roof Materials And Manufacturers
Materials used in fortified roofs must meet rigorous standards for impact, wind, and water resistance. Popular options include:
- Asphalt shingles – “Class 4” impact-rated
- Standing seam metal panels
- Concrete and clay tiles
- Synthetic/composite shingles
Products from leading brands like Owens Corning, GAF, CertainTeed, and TAMKO offer FORTIFIED-compliant lines. Always verify certification with the installer and IBHS documentation.
Common Myths And Facts About Fortified Roofs
- Myth: Only New Roofs Can Be Fortified – Fact: Many existing roofs can be upgraded, particularly at reroofing time.
- Myth: Fortified Roofs Look Unattractive – Fact: Appearance is identical to standard roofs—upgrades are hidden beneath surface materials.
- Myth: Fortified Roofs Are Only For Coastal Homes – Fact: Valuable wherever severe weather strikes, including inland tornado and hail zones.
- Myth: Maintenance Is Difficult – Fact: Maintained like any standard roof—periodic inspection and minor repairs.
How To Verify A Fortified Roof System
Not every upgraded roof meets FORTIFIED standards. The official FORTIFIED certificate, issued by IBHS through a licensed evaluator, is the only proof of compliance. Ask potential contractors for references and previous FORTIFIED projects.
Check your insurance company’s requirements—they may request inspection reports or photos as proof for discounts.
FORTIFIED Roof Vs. Standard Roof: What’s The Difference?
| Feature | Standard Roof | FORTIFIED Roof |
|---|---|---|
| Code Requirements | Local minimums | Exceeds code; IBHS tested |
| Deck Sealing | Not required | Required on all seams |
| Fasteners | Staples or smooth nails | Ring-shank nails |
| Shingle/Material | Standard | Impact-rated |
| Certification | None | IBHS Certificate |
Real-World Examples: Fortified Roof Success Stories
After hurricanes like Ike (Texas) and Michael (Florida), FORTIFIED homes were consistently less damaged than their neighbors. In pilot programs in Alabama, fortified roofs reduced insurance claims by as much as 50% following severe storms.
Post-storm aerial photos show entire neighborhoods with conventional roofs destroyed, while fortified roofs remain in place, keeping families and their possessions safe.
Frequently Asked Questions About Fortified Roofs
How Long Does Certification Last?
IBHS FORTIFIED certification is valid for up to five years, after which re-evaluation is recommended to ensure all components remain up to standard. Maintenance or replacement of damaged roof sections may be needed to maintain certification and insurance discounts.
Can You Retrofit An Existing Roof?
In many cases, yes. During roof replacement (when old shingles/tiles are removed), it’s possible to seal the deck and upgrade fasteners for FORTIFIED compliance. Some improvements—like metal connectors—may require access from inside the attic.
Do FORTIFIED Roofs Work With Solar Panels?
Absolutely. Roofs can be fortified before solar installation, or panels can be replaced after a FORTIFIED retrofit. Discuss with your contractor to ensure all penetrations are properly sealed to maintain resilience standards.
How Do I Find FORTIFIED Contractors Or Evaluators?
The IBHS website (https://fortifiedhome.org/) maintains a public searchable database of certified contractors and evaluators by region. Always verify credentials before starting your project.
Is A Fortified Roof Right For Your Home?
With increasing storm risk, a fortified roof is one of the best investments homeowners can make in property protection. Evaluate your local risks, budget, and potential insurance savings by talking with contractors, insurers, and the IBHS. Upgrading your roof to FORTIFIED standards could be the difference between minor storm cleanup and catastrophic property loss.
