    FORTIFIED Roofing

    A FORTIFIED roof is not a product you buy. It is a published construction standard your roof is built to, and then verified against by somebody who did not build it. This page explains both halves honestly — the part we do, and the part that is deliberately not ours.

    Carolina Trophy Roofs is a FORTIFIED certified roofer, serving Rocky Mount, Greenville, Wilson, Tarboro and across Eastern North Carolina.

    What FORTIFIED is, and what it is not

    FORTIFIED is a voluntary resilience construction standard published by the Insurance Institute for Business & Home Safety (IBHS). It is a written set of requirements — fasteners, sealing, edges, coverings, vents — that a building can be constructed to and then independently verified against. Meet them, and IBHS issues a designation for that specific address.

    Voluntary is the key word. Your building code sets a floor. FORTIFIED sits above that floor on purpose, in the places where post-storm investigation keeps finding the same failures. Nobody makes you do it. You choose it, and then you have to prove it.

    It is worth being just as clear about what FORTIFIED is not. It is not a claims service and has nothing to do with how a loss is handled. It is not a product warranty and it is not a guarantee that a roof will survive any particular storm — no honest standard promises that, and neither do we. It is not a brand of shingle. And it is not something a roofing company can award itself, which is the point of the next section.

    Why this matters here specifically

    Eastern North Carolina is flat, low and close to the water, and tropical systems arrive here still organized. Two things about that geography change what a roof has to survive.

    The first is the nature of the load. Wind does not shove a roof down; it lifts it. Air accelerating over the roof plane drops the pressure above the surface while the attic underneath stays close to ambient, and the net force points up and off. That suction is worst where the airflow separates — eaves, rakes, corners and the ridge — which is exactly where FORTIFIED concentrates its attention. And because the wind arrives in gusts, the load is cyclic: a connection that would hold a steady pull can still be worked loose by several hours of pulsing at it.

    The second is the rain. In a hurricane, rain does not fall — it travels horizontally at whatever the wind is doing, and it will find any gap designed on the assumption that water arrives from above: shingle edges, vent openings, every seam in the deck.

    Put those together and you get the failure sequence that repeats across this region after every named storm. An edge lifts. The wind gets under the course above it and the covering peels back. The deck is now exposed, and horizontal rain pours through the seams. Then the deck fasteners start working under the uplift, and if they let go, a whole sheet of decking leaves and the house is open to the sky. Almost every requirement in the FORTIFIED roof level is aimed at interrupting that sequence at one of its steps, which is what makes it a coherent standard rather than a list of upgrades.

    FORTIFIED roof requirements: what the roof actually has to have

    These are the roof-level requirements. Each one exists because something specific fails without it, so they are set out here with the reason attached rather than as a checklist.

    A sealed roof deck

    The plywood or OSB under your shingles is sealed as a water barrier in its own right — a self-adhered membrane over the deck, or the deck seams taped and then covered with underlayment.

    When shingles come off in a hurricane, an ordinary roof is a field of open seams, and the rain is not falling on it — it is being driven into it sideways. IBHS puts the volume in terms anyone can picture: for every inch of rain that hits an exposed roof deck, the equivalent of nine bathtubs of water can pour in. A sealed deck shuts those seams. That is usually the difference between a wet ceiling and a gutted house.

    Ring-shank deck attachment in the enhanced pattern

    IBHS states it plainly: "Instead of common smooth nails, FORTIFIED requires ring-shank nails, installed in an enhanced pattern, to help keep the roof deck attached to your home in high winds." In practice that means 8d ring-shank nails and closer spacing than the minimum a builder would otherwise use.

    Wind does not press down on a roof; it pulls up on it, and it arrives in gusts, so the load is cyclic rather than steady. A smooth nail under repeated uplift works like a nail being drawn — it backs out a fraction at a time. A ring-shank nail has to tear wood fiber to move. Deck attachment is the difference between losing shingles and losing a whole sheet of decking, which is the point at which the house is simply open.

    Locked-down edges

    A wider drip edge than standard practice, and a fully adhered starter strip — installed together, and beyond what the covering manufacturer requires as a minimum.

    Nearly every wind failure on a shingle roof starts at an edge. Wind cannot get under a continuous surface, so it goes looking for a lip: an eave, a rake, a corner. Once one starter course lifts, the wind is underneath the field shingles and the roof unzips from that point. Locking the perimeter denies the storm its first handhold — the cheapest part of the standard and, dollar for dollar, probably the part that earns the most.

    A covering that carries the required ratings

    Asphalt shingles have to meet the highest wind ratings — ASTM D3161 Class F or ASTM D7158 Class H. Metal and tile systems have to be tested for the design pressures at your specific site, and low-slope systems the same.

    A wind rating is a test result at a stated wind speed, not marketing copy. The site-specific part matters here because design pressure is not one number for the state — it changes with distance from the coast, exposure, building height and roof shape. A panel that is correct in Rocky Mount is not automatically correct on a bare lot near the sound.

    Vents tested against wind-driven rain

    Attic vents on a FORTIFIED roof have to be wind and rain resistant — tested, not assumed.

    A vent is an intentional hole in an otherwise sealed plane, and every roof needs them. Ordinary vents are designed to keep out rain that falls; hurricane rain does not fall, and an ordinary vent will pass it straight into the attic while the roof above stays perfectly intact. That is why a house can come through a storm looking untouched with soaked insulation. Tested vents are also the item most often value-engineered out of a bid by someone who has not read the standard.

    What a sealed deck looks like before the covering goes on

    These are from one of our own jobs in Eastern North Carolina, July 2026. This is the part of a FORTIFIED roof nobody ever sees — by the end of the same day it is under underlayment and shingles, and from that point on the only evidence it was done right is a photograph taken while it was open.

    Look at the grid of tape across the deck in the first picture: every seam between every sheet of sheathing, sealed. Note also what is stamped into the corner of each frame — the date and the coordinates. A photograph that carries its own time and place is worth considerably more to an evaluator than one that does not.

    A fully adhered starter at the edge is a FORTIFIED requirement, because the edge is where wind gets its first handhold. This is one product that meets it — a self-adhering starter that bonds to the deck rather than relying on a cut shingle tab and its own sealant strip.

    What these pictures do and do not show: work built to FORTIFIED requirements — a sealed deck and a fully adhered starter are both requirements of the standard. They are not proof that this address was issued a designation, which is not something a photograph can establish. Only IBHS issues a designation, and only after an independent evaluator has verified and submitted the documentation.

    The three designation levels

    The levels ascend, and each one contains the one below it. Which is realistic for you is mostly a question of how much of the building is being opened up.

    1. Level 1

      FORTIFIED Roof

      The roof, done to the standard

      The sealed deck, ring-shank attachment in the enhanced pattern, locked-down edges, a rated covering and tested vents. This is the level nearly every existing home starts at, because it is the level you can reach during a re-roof without touching the rest of the house.

    2. Level 2

      FORTIFIED Silver

      Everything in Roof, plus the openings and what is bolted on

      Silver moves past the roof plane to the other places a storm gets in or gets leverage — stronger garage doors, anchored carports and porches, and reinforced chimneys and gable ends. It is a bigger project than a re-roof and usually planned as one.

    3. Level 3

      FORTIFIED Gold

      Everything in Silver, plus a continuous load path

      Gold requires an engineered continuous load path: a specific plan for how the roof is fixed to the walls and how the walls are anchored to the foundation, so uplift and lateral loads have a positive connection all the way to the ground. It involves an engineer, not just a roofer, and it is most realistic on new construction or a substantial renovation.

    The 2025 standard and the November 1 date

    IBHS states it directly: “All projects permitted on or after November 1, 2025 must meet the requirements of the 2025 FORTIFIED Home™ Standard.” IBHS adds that in locations where roof permits are not required, roofs installed on November 1, 2025 or later must meet those requirements too.

    For anyone planning work now, that means the 2025 standard is simply the standard. The permit date is the hinge, not the contract date and not the date the crew shows up — so if a job has been sitting quoted for a while, the version it was scoped against is worth re-checking before it goes to permit.

    Practically, the thing to guard against is a bid written from an older set of documents. Ask which version of the standard your roofer is building to and which version your evaluator will be checking against, and make sure those two answers are the same one. The current documents, including the standard itself, a summary of what changed, and the evaluator checklists, are published openly by IBHS at fortifiedhome.org. You are allowed to read them. Most homeowners never do, and the ones who skim the evaluator checklist ask noticeably better questions.

    Who does what: the evaluator is not the roofer

    This is the part of FORTIFIED most worth understanding before you hire anyone, because it is the mechanism that makes the whole thing credible. The roofer who builds the roof cannot be the person who certifies it. IBHS describes FORTIFIED Evaluators as independent, third-party contractors trained in the FORTIFIED requirements, and it is the evaluator who documents and verifies the construction process. A designation a contractor could issue to its own work would be worth nothing — not to an insurer, not to a buyer, not to you. The separation is the product.

    Both sides of that split train through the same program. IBHS runs FORTIFIED Wise™, its training and certification course for building professionals, and publishes a public directory of the roofers, builders and evaluators who have completed it. You can look up anybody you are considering — including us — before you sign anything.

    What we do

    Build the roof to the standard, and photograph the work that is about to be covered up — deck condition, fastener type and pattern, sealed seams, edge details, material labels. If it was not recorded while it was open it cannot be verified later. That documentation is the deliverable a roofer new to FORTIFIED work most often underestimates.

    What the evaluator does

    An independent, IBHS-trained evaluator — a separate party from us — verifies the work against the standard and submits the documentation to IBHS. IBHS is explicit that some contractors have evaluators they prefer to work with, but that you should always be free to make your own selection. Take them up on that.

    What IBHS does

    IBHS reviews what the evaluator submits and issues the designation. In their words, the document is issued by IBHS after a review of the documentation provided by a FORTIFIED evaluator, and the certificate goes to the evaluator, who delivers it to you.

    Because the evaluator is a separate party, here is one: NC Fortified LLC is a FORTIFIED evaluation practice covering coastal and eastern North Carolina. Most homeowners pick their own evaluator, and IBHS is clear that you should always be free to make your own selection. You can search the full IBHS provider directory and pick anyone on it.

    FORTIFIED is a program of IBHS. IBHS issues the designation, not the contractor.

    What you end up holding, and what to do with it

    At the end you have a designation certificate for your address. IBHS describes a designation as written certification that a home or business has been built, renovated or re-roofed according to FORTIFIED standards. It runs five years from the date it was issued, and renews by re-inspection — IBHS notes that where the roof is in good condition and no modifications have been made, the inspection is likely the only step required. Renewal is available through the standard process and fees up to a year past expiration, and the expiration date is printed on the certificate. Put it in your calendar the week it arrives.

    You should also end up with the build record: the photographs of everything now sealed under the shingles. Keep that with the certificate — it answers a question in year four that nobody can settle by looking at the roof. And keep the certificate somewhere you can find it when you sell. It is one of the few pieces of paper about a roof that a stranger can read and immediately understand.

    Then there is the insurance question, which is why a lot of people look into FORTIFIED in the first place. We will not tell you what your policy does — no roofer should. What we can explain is the mechanism. Insurance carriers file their rates and their mitigation credit structures with the state, and it is in those filings that the conditions for any wind-mitigation credit are set out, along with what documentation proves it. Where such a credit applies, it attaches to the wind and hail portion of the premium, because that is the portion the roof has anything to do with. The IBHS designation certificate is the trigger: independent, third-party evidence that a specific address meets a specific published standard.

    Whether that produces anything on your bill, and how much, depends on your carrier, your county and your policy form. So do it in the right order: before you commit to the work, take the question to your own insurance agent and ask for a written premium illustration with and without the designation. If a roofing company quotes you a savings figure instead, they are guessing at something they have no way to know. The North Carolina Department of Insurance regulates homeowners insurance in this state and is a reasonable second place to take a question your agent does not answer clearly.

    What to ask any roofer before hiring for FORTIFIED work

    Ask us these too. A contractor who is genuinely doing this work will have quick, specific answers, and one who is using the word as a marketing term will not.

    • Are you listed in the IBHS FORTIFIED provider directory, and under exactly what company name? Look it up yourself before the contract, not after.
    • Which version of the standard are you building to, and when will this job be permitted? Anything permitted on or after November 1, 2025 is a 2025-standard job.
    • Which evaluator are you expecting to use — and am I free to choose my own? IBHS is explicit that you should always be free to make your own selection.
    • Who engages and pays the evaluator, and is that written into my contract or handled separately by me?
    • What exactly gets photographed, and at which stage? Ask for the list of concealed-work items by name. If a roofer cannot tell you what a deck-nailing photograph has to show, that is your answer.
    • What happens if the evaluation turns up something non-conforming — who corrects it, and at whose cost? Settle that before anyone is on the roof.
    • Which shingle, and what is its wind-rating designation? You want the specific ASTM class, not "it is a good shingle."
    • Which vents are on the spec, and are they tested for wind-driven rain? This is the item most likely to be quietly substituted.
    • Will the estimate line out the FORTIFIED-specific materials and labor separately, so I can see what the upgrade actually consists of?

    Grants and insurance credits for a FORTIFIED roof in North Carolina

    There are two pots of money people ask about, and they work differently. The first is an insurance credit. The NC Department of Insurance states that mitigation credits can provide premium discounts for wind and hail coverage on homes with qualifying construction features, that using the FORTIFIED program could mean eligibility for those credits, and that the way to find out is to contact your agent or insurance company. Ask for the answer in writing, with and without the designation.

    The second is a grant. The North Carolina Insurance Underwriting Association — the coastal wind pool that NCDOI describes on its windstorm and hail page — has run a grant program for FORTIFIED Roof upgrades for its own policyholders. The amounts, the eligibility rules and the application windows are set by NCIUA for each round and published by NCIUA (nciua.com), not by roofers; a figure you hear on a sales call is out of date or invented. IBHS maintains a list of current FORTIFIED incentives by state. Our part is the roof and its documentation; the money questions belong to your agent, NCIUA and IBHS.

    FORTIFIED Roofing: Common Questions

    Thinking about a FORTIFIED roof?

    The right time to have this conversation is before the roof is scoped, because the standard changes the specification rather than getting added to it afterwards. We will look at your roof, tell you what it would take, and be straight with you about which parts are ours and which parts are not.
