Quick answer
FORTIFIED is a voluntary construction and re-roofing standard from the Insurance Institute for Business & Home Safety. It is not a roofing brand or a hurricane-proof guarantee. Its practical goal is to make it harder for wind to start peeling the roof away, keep the wood roof connected to the home, and limit rain entry if shingles or panels are damaged. The technical methods include stronger edges, a sealed roof deck, enhanced deck attachment, and a tested roof covering. An independent evaluator documents the work before IBHS issues a designation.
- FORTIFIED protects more than the visible surface. Hidden layers help keep rain out and the roof connected when storms damage shingles or panels.
- Metal panels, asphalt shingles, tile, and other approved roof covers can be part of a FORTIFIED Roof.
- The evaluator should be involved before work begins because key details must be documented during installation.
- Insurance benefits vary. A designation may help, but the homeowner must confirm eligibility and savings with the insurer.
What FORTIFIED is
FORTIFIED is a voluntary program developed by the Insurance Institute for Business & Home Safety, often called IBHS. The standard is designed to reduce damage from severe weather by strengthening vulnerable parts of a home and documenting that the required work was completed.
For a homeowner replacing a roof, the most relevant level is usually FORTIFIED Roof. Higher FORTIFIED levels address additional parts of the home, but the roof designation concentrates on keeping wind and rain from turning roof-cover damage into a larger failure.
FORTIFIED is more than choosing a product with a strong wind label. It combines materials, installation details, observation, documentation, and review. A roof that uses some FORTIFIED-like details is not the same as a roof that earned an active designation.
The four roof protection layers homeowners should understand
Stronger roof edges
Wind can get beneath a vulnerable edge and begin peeling the roof system away. FORTIFIED specifies edge and starter-strip details intended to make that starting point harder to lift.
Backup protection from rain
If shingles or panels are damaged, gaps in the wood beneath them can let rain into the attic and living space. A sealed roof deck covers those gaps with a backup water barrier.
A roof that stays connected
High wind pulls upward on the roof. Stronger fasteners placed in a tested pattern help keep the wood roof deck connected to the home instead of lifting away.
Proof the visible roof fits the home
The shingles, metal panels, tile, or other covering must be tested for the wind forces expected at the home. This product testing is the proof behind the technical rating.
Metal and asphalt can both qualify
FORTIFIED is not a metal-roof-only program. IBHS allows several roof cover types when they meet the applicable requirements. This matters because a homeowner can start with budget and appearance, then decide whether metal panels, metal shingles, asphalt shingles, tile, or another eligible system fits the project.
For homeowners, the important question is whether the chosen metal panel or asphalt shingle has proof that it can handle the wind forces at the home. Metal uses site-specific design-pressure testing, while asphalt uses qualifying high-wind ratings. Both still need protected edges, a backup water barrier, strong attachment, sealed roof openings, and documentation beneath or around the visible covering.

Contractor, evaluator, and designation: three different roles
- 1
Discuss the goal before the quote is final
Tell the contractor that an official FORTIFIED designation is a project requirement, not simply a preference for stronger materials.
- 2
Engage an independent FORTIFIED evaluator
The evaluator plans the documentation process, observes required stages, and records details that will be hidden after the roof is complete.
- 3
Install the specified system
The contractor completes the work that keeps the roof attached and water out, including the wood deck, backup water barrier, protected edges, ventilation, sealed wall and vent connections, and the visible roof covering.
- 4
Submit documentation for review
The evaluator sends the required evidence through the FORTIFIED process. IBHS reviews it before issuing a designation.
- 5
Maintain the designation and roof
Keep the designation, invoices, product records, photos, warranties, and maintenance information. Confirm renewal requirements with FORTIFIED and the insurer.
Insurance and incentives: ask before assuming
Some states and insurers offer discounts, grants, tax benefits, or other incentives connected to wind-mitigation work or FORTIFIED designations. Availability, eligibility, documentation, timing, and savings vary.
Ask the insurance agent what designation is required, whether the policy recognizes it, which documents must be submitted, whether the benefit continues at renewal, and whether the roof material affects underwriting. Do not approve a larger project solely because someone promises an insurance discount that has not been confirmed in writing.
Questions to answer before signing
- Which FORTIFIED standard applies to the permit date and location?
- Who is the independent evaluator, and when must the evaluator inspect the work?
- Which exact roof covering and wind or design-pressure rating are proposed?
- How will the roof stay attached at its edges, keep rain out if the covering is damaged, and seal around walls, vents, and screw points?
- What extra costs belong to the evaluator, documentation, repairs to the wood beneath the roof, or required upgrades?
- What happens if hidden deck damage is discovered after tear-off?
- Which documents will I receive when the work and designation are complete?
- Has my insurer confirmed any discount or underwriting benefit in writing?
