An engineered construction standard from the Insurance Institute for Business & Home Safety — stronger storm protection, and potentially a lower insurance bill.
Get a Free EstimateFORTIFIED is a voluntary construction standard, not a brand of shingle. The Insurance Institute for Business & Home Safety (IBHS) developed it after decades of storm research. In short, it tells contractors exactly how to build a roof that survives the wind, rain, and hail that ordinary roofs cannot. Think of it less as a product and more as a proven recipe for a stronger roof.
Tennessee sits in the path of severe storms every spring and fall. High winds, driving rain, and hail batter homes across the state. A FORTIFIED roof from Jeff Woods Construction & Roofing is engineered to take that punishment, protect your family, and potentially lower your insurance bill in the process.
This guide walks you through what FORTIFIED actually means, how the roof gets built, what it costs, and how the insurance savings work. If you live in storm country, this is the standard worth understanding.
Most roofs fail in a storm at predictable weak points. Wind peels shingles off the edges first. Then water sneaks through the seams in the roof deck once shingles tear away. In extreme cases, poorly attached decking lifts off entirely under wind uplift. Once any of these fail, water pours into the home and the damage multiplies fast.
IBHS studied these failures for years at its research center, where engineers blast full-size houses with hurricane-force winds and rain. As a result, they learned something important. A handful of targeted upgrades, most of them inexpensive, dramatically improve how a roof survives a storm. FORTIFIED packages those upgrades into one clear standard. For a broader look at how Tennessee weather attacks roofs, our Storm Damage Roofing Guide for Tennessee Homeowners breaks it all down.
FORTIFIED comes in three tiers. Each level builds on the one before it, adding stronger protection. Here is how they stack up.
The foundation level, and most Tennessee homeowners choose it. It strengthens the part of your home that takes the most storm damage — the roof itself — with a sealed roof deck, stronger edges, and better-attached shingles. For most homes here, the biggest protection for the money.
Everything in the Roof level, plus protection for other openings — gable ends, soffits, and the connections that hold the roof structure to the walls. Suits homeowners who want protection beyond the roof surface itself.
The highest tier. It adds a continuous load path, tying the roof, walls, and foundation into one connected system so the whole structure resists storm forces as a single unit. For homeowners seeking maximum resilience.
A FORTIFIED roof differs from a standard roof in the details, and those details demand discipline at every step. Here is how Jeff Woods Construction builds to the standard.
First, we seal the seams of the roof deck so that even if shingles blow off, water still cannot get inside. This single upgrade prevents the majority of storm-related water damage. In fact, it is the heart of the entire FORTIFIED standard.
Next, we fasten the roof deck with ring-shank nails, which grip far more tightly than standard smooth nails. As a result, the deck stays put under extreme wind uplift that would tear off a conventionally nailed deck.
After that, we install stronger drip edge and lock down the perimeter, because wind almost always attacks a roof at its edges first. Reinforcing this zone stops the peeling failure that destroys ordinary roofs.
Then we install wind-rated shingles and nail them to the exact pattern the standard requires. Correct nailing matters as much as the shingle itself, since most wind failures trace back to poor attachment.
Finally, we document every step with photos and submit the package to a certified FORTIFIED evaluator. You then receive an official FORTIFIED designation, which is the proof your insurer needs. This paperwork is what unlocks your potential premium discount.
A FORTIFIED roof costs more than a standard roof, but less than most homeowners expect. The core upgrades — sealed deck, ring-shank nails, and reinforced edges — add only a modest amount to a quality roof replacement.
Why so reasonable? Because the biggest improvements come from better technique and a few inexpensive materials, not from exotic products. Essentially, you pay for precision and proper documentation. Our Roofing Cost Guide for Tennessee Homes puts that added cost in full context against a standard replacement.
Here is the part that changes the math, though. The insurance savings often offset the added cost over time, and the storm protection pays for itself the first time a major storm rolls through. Speaking of which, let’s look at those savings next.
This is where FORTIFIED gets interesting for your wallet. Many insurers offer meaningful premium discounts for a certified FORTIFIED roof, because the data proves these roofs file fewer and smaller claims.
The discount varies by insurer and policy, but homeowners frequently see a reduction on the wind and hail portion of their premium. Over the life of the roof, those annual savings can recover much of the upfront upgrade cost. In other words, you pay a little more once and potentially save every year afterward.
A few practical tips will help you capture the savings:

A FORTIFIED roof makes the most sense in specific situations. Consider it strongly if any of these describe you.
You live in a storm-prone area, which covers much of Tennessee. You are already replacing your roof, since that is the natural moment to upgrade. Your insurer offers a FORTIFIED discount that improves the long-term math. Or perhaps you simply want the strongest protection available and the peace of mind that comes with it.
On the other hand, if your current roof is young and healthy, you do not need to rush a replacement just to go FORTIFIED. Instead, the smart move is to plan for it when your roof reaches the end of its life. Not sure where your roof stands? Our Roof Repair or Replacement guide and a free roof inspection will tell you.
Homeowners often ask how a FORTIFIED roof truly differs from a good standard roof. The table below makes it clear.
| Feature | Standard Roof | FORTIFIED Roof |
|---|---|---|
| Roof Deck Seams | Unsealed | Sealed against water |
| Deck Fasteners | Smooth nails | Ring-shank nails |
| Edge Protection | Basic drip edge | Reinforced edges |
| Shingle Attachment | Standard nailing | Enhanced nailing pattern |
| Third-Party Certification | None | Certified by IBHS evaluator |
| Insurance Discount | Rarely | Often available |
The shingles may look identical from the street. The difference lives in the deck, the edges, and the fasteners, where storms actually do their damage. Our What Is Fortified Roofing and Is It Worth It for Tennessee Homeowners? article explores this comparison in even greater depth.
FORTIFIED defines how a roof gets built, but you still choose the roofing material on top. Most Tennessee homeowners pair the standard with quality asphalt shingles, and we install GAF products certified to the wind ratings FORTIFIED requires. Our GAF Roofing Systems Explained guide explains why certified materials matter for both performance and warranty.
Prefer an even tougher surface? Metal roofing pairs beautifully with FORTIFIED principles, since metal already resists wind and hail exceptionally well. Either way, the FORTIFIED upgrades beneath the surface make a strong material even stronger.
A FORTIFIED roof still benefits from regular care, just like any roof. Good maintenance protects both your investment and your certification. We recommend these habits for Tennessee homeowners.
Stay consistent, and your roof keeps protecting your home and your premium for years. Our Roof Maintenance Guide for Tennessee Homes offers a full seasonal checklist, and our Roofing Maintenance for High-Wind Areas article adds storm-country specifics.

A FORTIFIED roof is built to a voluntary construction standard created by IBHS, a leading insurance research institute. It strengthens the weak points where roofs usually fail in storms, such as the deck seams, edges, and fasteners. A certified evaluator then verifies the finished work. Our What Is Fortified Roofing article explains the full standard.
The discount varies by insurer and policy, and it typically applies to the wind and hail portion of your premium. Many Tennessee homeowners see meaningful annual savings. Always confirm the exact discount with your agent before you start the project.
For most storm-exposed Tennessee homes, yes. The core upgrades add a modest amount upfront, and the insurance savings plus storm protection often recover that cost over time. The peace of mind during severe weather is a real benefit too.
Not exactly. The standard requires wind-rated shingles installed to a specific nailing pattern, along with a sealed deck and reinforced edges. We pair FORTIFIED with certified GAF shingles or metal roofing, depending on your preference.
No. A FORTIFIED roof requires a contractor who knows the standard and follows it precisely, plus a certified evaluator who verifies the work. Without that documentation, the roof cannot earn its designation or qualify for insurance discounts.
FORTIFIED designations carry a renewal cycle, typically five years. When the time comes, we help you re-certify so your protection and any insurance discount stay in place.
Usually not. Because the standard depends on the sealed deck and proper fastening beneath the shingles, FORTIFIED works best during a full roof replacement. That is the natural moment to build the upgrades in correctly.
