Alabama FORTIFIED Home Discount Calculator (2026)
What FORTIFIED is
FORTIFIED is a voluntary construction and re-roofing standard developed by the Insurance Institute for Business & Home Safety (IBHS) to make homes dramatically more resistant to severe weather — especially the high winds that drive most Alabama insurance losses. It is verified by a certified evaluator and comes in three escalating levels: Roof, Silver, and Gold.
Why Alabama leads the nation
Alabama has more FORTIFIED designations than any other state because it pairs two things: a state law requiring insurers to recognize FORTIFIED with premium credits, and the Strengthen Alabama Homes grant program that helps homeowners pay for the upgrade. The Alabama Department of Insurance publishes the mitigation discount framework insurers use (source: ALDOI Windstorm Damage Mitigation handout).
The three FORTIFIED levels
- FORTIFIED Roof — a sealed roof deck, enhanced edge metal and improved shingle attachment to keep wind and water out. This is the entry level and the focus of most retrofits.
- FORTIFIED Silver — everything in Roof plus protection for openings and attached structures (gable ends, chimneys, porches, soffits).
- FORTIFIED Gold — everything in Silver plus a continuous load path that ties roof, walls and foundation together to resist uplift. Gold earns the largest insurance credit.
Estimated discount calculator
Alabama's FORTIFIED credit applies to the wind (or hurricane) portion of your premium — not your entire bill — and it grows with each level. Coastal homes in Mobile and Baldwin counties receive the largest credits; inland homes receive smaller ones. The table below shows the direction and relative size of the credit by level and region. We deliberately do not publish a single carrier's exact percentage, because those figures are set in each insurer's filing and vary by company and address.
| FORTIFIED level | Coastal (Mobile / Baldwin) | Inland Alabama | Applies to |
|---|---|---|---|
| Roof | Entry-level wind-premium credit | Smallest wind-premium credit | Wind / hurricane portion only |
| Silver | Larger than Roof | Larger than Roof | Wind / hurricane portion only |
| Gold | Largest credit available | Largest inland credit | Wind / hurricane portion only |
Per the ALDOI windstorm mitigation handout, mitigation credits in Alabama can reduce a substantial share of the wind/hurricane portion of premium, with the heaviest discounts reserved for Gold-certified coastal homes. To turn this into a dollar figure, take your current premium, ask your agent what share is the wind/hurricane portion, and apply your carrier's filed credit for your level and county. To estimate yours: note your annual premium and FORTIFIED level, then ask an independent agent to run your address against carriers that price FORTIFIED most favorably.
How to qualify
Earning a designation is a defined process:
- Find a certified FORTIFIED evaluator through IBHS FORTIFIED.
- Complete the qualifying roof work or full retrofit using compliant materials and methods.
- Have the evaluator inspect and submit documentation for the FORTIFIED designation.
- Provide the FORTIFIED certificate to your insurer so the wind-premium credit is applied.
- Keep the certificate and as-built paperwork for renewals, underwriting and any future claim.
Strengthen Alabama Homes grant
The Strengthen Alabama Homes program provides grants to help homeowners retrofit an existing home to the FORTIFIED Roof standard, lowering the out-of-pocket cost of the upgrade. Grant amounts, eligibility and application windows change between funding cycles, so check the official program site for the current round before you plan a retrofit.
Working with an independent agent
TCDS Agency is an independent, carrier-neutral broker. Because FORTIFIED credits vary by insurer, the same designation can be worth more with one carrier than another.

FORTIFIED discounts in Alabama at a glance
Alabama leads the nation in IBHS FORTIFIED construction because state law requires insurers to recognize the standard with premium credits, and the Strengthen Alabama Homes grant helps homeowners pay for the upgrade. The discount applies to the wind portion of your premium, and it grows with the certification level — Roof, Silver, then Gold (source: Alabama Department of Insurance).
Because the credit is a percentage of only the wind portion of premium, your actual dollar savings depend on your carrier, your county and how your premium is split between wind and other perils — coastal Mobile and Baldwin County homes see the largest credits. Use the ranges below to estimate, then ask an independent agent to shop carriers that price FORTIFIED most favorably for your address. We never quote a single carrier's exact percentage here because those figures come from each insurer's filing.
| FORTIFIED level | Typical wind-portion credit range* | Official source |
|---|---|---|
| Roof | Lower-tier credit (smaller % of the wind premium). | ALDOI |
| Silver | Mid-tier credit (larger than Roof). | ALDOI |
| Gold | Top-tier credit (largest % of the wind premium). | ALDOI |
| Coastal vs. inland | Coastal (Mobile/Baldwin) credits exceed inland credits. | ALDOI |
| Applies to | The wind/hurricane portion of premium — not the whole bill. | ALDOI |
| Grant help | Strengthen Alabama Homes can offset retrofit cost. | SAH |
*Exact percentages are set by each insurer's filing and vary by county; ALDOI publishes the schedule insurers use. Ranges compiled from the ALDOI windstorm mitigation handout, IBHS FORTIFIED and Strengthen Alabama Homes. Confirm your carrier's actual credit before relying on any figure.

Frequently Asked Questions
What is a FORTIFIED home?
FORTIFIED is a voluntary construction and re-roofing standard from the Insurance Institute for Business & Home Safety (IBHS) that strengthens a home against severe weather, especially high wind. It comes in three levels — FORTIFIED Roof, Silver, and Gold — each adding protections such as sealed roof decks, stronger edges and attachments, and upgraded connections from roof to foundation.
How much can I save with a FORTIFIED discount in Alabama?
Alabama law requires insurers to give premium credits for FORTIFIED construction, applied to the wind or hurricane portion of your premium. Credits increase from Roof to Silver to Gold and are largest in coastal Mobile and Baldwin counties. Because the credit applies only to the wind portion and exact percentages are set by each insurer's filing, your dollar savings depend on your carrier, county and premium mix — ask an independent agent to compare.
What are the three FORTIFIED levels?
FORTIFIED Roof focuses on the roof system — a sealed roof deck, enhanced edge metal, and better shingle attachment to resist wind and water intrusion. FORTIFIED Silver adds protection for openings and attached structures like gable ends, chimneys and porches. FORTIFIED Gold adds a continuous load path that ties the roof, walls and foundation together so the whole structure resists uplift.
Why does Alabama lead the nation in FORTIFIED homes?
Alabama combines a state law requiring insurers to recognize FORTIFIED with premium credits and the Strengthen Alabama Homes grant program, which helps homeowners pay for retrofits. That pairing of mandated insurance recognition and grant funding has produced more FORTIFIED designations in Alabama than in any other state.
What is the Strengthen Alabama Homes grant?
Strengthen Alabama Homes is a state program that provides grants to help homeowners retrofit existing homes to the FORTIFIED Roof standard, reducing out-of-pocket cost for the upgrade. Eligibility, grant amounts and application windows change over time, so check the official Strengthen Alabama Homes website for current details and to apply.
How do I qualify for a FORTIFIED discount?
Your home must earn an IBHS FORTIFIED designation through a certified evaluator who inspects and documents that the work meets the standard. Once designated, give the certificate to your insurer to apply the wind-premium credit. To start, find an evaluator through IBHS, consider the Strengthen Alabama Homes grant if retrofitting, and keep all certification paperwork for underwriting and claims.
