Hurricane-resistant roofing in North Carolina

A roof that holds in a North Carolina hurricane is a system: a deck nailed down properly, a sealed deck or secondary water barrier, secured edges and ridge, and a covering rated for the wind where the house sits. No roof can be made immune to hurricanes. This guide covers the state's storm record, the coastal wind code, the FORTIFIED Roof standard and what to check before and after a storm.

How often do hurricanes hit North Carolina?

Often: from 1851 to 2019, North Carolina had a direct hurricane landfall every two years on average, according to the State Climate Office of North Carolina, which lists 36 storms that came ashore here at hurricane strength. Storms that make landfall somewhere else still reach the state as tropical storms and remnants.

The Atlantic season runs from June 1 to November 30, and the National Hurricane Center puts its peak on September 10, with most activity from mid-August to mid-October.

Do hurricanes damage roofs far from the coast?

Yes. The State Climate Office says strong storms can still produce damaging winds well inland, and that even weak hurricanes and tropical storms damage well-built homes, mostly through falling branches and trees. Three recent storms show the range:

Hurricane Florence, September 2018

Made landfall near Wrightsville Beach on September 14 as a Category 1 hurricane, with gusts of 105 mph at Wilmington International Airport and 106 mph at Cape Lookout. It stalled, and 35.93 inches of rain fell northwest of Elizabethtown, more than this part of the state had ever recorded from one storm (NWS Wilmington).

Hurricane Matthew, October 2016

Brought 12 to 15 inches of rain from Lumberton and Fayetteville to Goldsboro, with up to nearly 19 inches in spots. The Neuse River set record crests at Smithfield and Goldsboro, and gusts topped 50 mph across most of the state east of I-95 (NWS Raleigh).

Helene, September 2024

Hit western North Carolina hundreds of miles from the coast: 24.41 inches of rain on Mount Mitchell, a 106 mph gust there, and a 66 mph gust at Charlotte's airport. The State Climate Office called the river flooding the new flood of record for the region, replacing July 1916.

What wind speed does a North Carolina roof have to meet?

It depends on where the house is: the North Carolina Residential Code assigns a design wind speed by location, and the coast sits in the higher zones. The 2018 edition is the one in force until the delayed 2024 edition takes effect, according to the Office of State Fire Marshal.

One threshold matters for homeowners near the water. Where the design wind speed is 130 mph or more, the State Fire Marshal's office says the code's standard fastening table no longer applies and the structure needs wind analysis. That is higher than the 120 mph Interlock wind rating (installed to manufacturer specification), so on an exposed coastal lot the engineer or your county or city inspections department sets the requirement for your house, and the roof has to be built to it.

Ask any roofer which design wind speed applies to your address and how the roof will be fastened to meet it. If the answer is a brochure number, keep asking.

What makes a roof hold in a hurricane?

The details under and around the covering matter as much as the covering. These are the parts that fail first, and the parts to ask about on any quote.

Deck attachment

The roof covering is only as strong as the plywood or OSB under it, and the deck is only as strong as its nails. IBHS says ring-shank nails in an enhanced pattern nearly double the roof's strength against wind compared with smooth nails. On a re-roof, the deck is the one chance to fix this for decades.

A sealed deck and secondary water barrier

If wind strips part of the covering, a sealed deck keeps rain out of the attic. The FORTIFIED Roof standard requires the deck seams to be sealed. Ask what goes between the deck and the panels, and how the seams are treated.

Edges, rakes and ridge

IBHS says roof damage often begins when wind gets under the roof edge. Wider drip edge, a fully adhered starter course on shingle roofs, and fastened ridge and rake trim are where a roofer's details show.

A covering tested for the design pressure

FORTIFIED requires metal, tile and low-slope coverings to be tested for the design pressures at the house's location. Ask for the product's wind rating, and what installation the rating assumes.

Vents, chimneys and attached roofs

Ridge and gable vents rated for wind and rain, a braced chimney, and porch and carport roofs anchored to the structure. A detached porch roof can take the main roof with it.

Trees

The State Climate Office notes that even weak hurricanes and tropical storms damage well-built homes, mostly through falling branches and trees. A tree survey is cheaper than a new roof.

What is the FORTIFIED Roof standard?

FORTIFIED Roof is a standard from the Insurance Institute for Business & Home Safety (IBHS) that strengthens the whole roof system: IBHS lists an enhanced deck-nailing pattern with ring-shank nails, a sealed roof deck, a wider drip edge and adhered starter on shingle roofs, and roof coverings rated or tested for the site's wind pressure. A third party verifies each installation before it is designated.

In North Carolina it can affect what you pay for insurance. The NC Department of Insurance says a FORTIFIED Roof gives policyholders insurance credits that reduce their premiums, and the NC Insurance Underwriting Association has run Strengthen Your Roof grant programs for eligible NCIUA policyholders in coastal counties. Discounts vary by insurer and location, and grant programs open and close, so get the current terms in writing from your agent and from NCIUA before you sign a roofing contract.

If you want a FORTIFIED designation, say so before the contract, so the requirements and the evaluator are planned in from the start. The designation is IBHS's decision, not the roofer's.

How does an Interlock aluminum roof handle wind?

Interlock aluminum panels interlock on all four sides with concealed fasteners, so there is no exposed screw head and no loose tab for wind to lift. Wind resistance is warranted to 120 mph when installed to manufacturer specification. Where your site's design wind speed is higher, the roof has to be designed and fastened to that requirement, and we work to what the permit office and engineer set.

Heavy-gauge aluminum does not rust, so it is corrosion-resistant in the salt air from Wilmington to Morehead City and New Bern. The panels weigh roughly 0.4 to 0.7 lb per square foot, and every profile needs a minimum 3/12 slope.

One thing to know before a storm: the Guardian Lifetime Limited Material Warranty covers manufacturing defects in the material and finish and excludes damage from severe weather events. Hurricane damage is a homeowners-insurance matter. Metal Roof NC, an authorized Interlock dealer, installs the system; Interlock Roofing manufactures it.

How should I get my roof ready for hurricane season?

Start in spring, well before the August-to-October peak.

Clean gutters and downspouts in late spring, and again before the peak weeks of August through October.
Have overhanging limbs and dead trees near the house checked by an arborist.
Look at the roof from the ground with binoculars: lifted shingles or trim, loose flashing, damaged vents.
Photograph the roof and attic now, with dates, so you can show the condition before a storm.
Read your homeowners policy: the hurricane or windstorm deductible, and whether you have a separate wind policy.
Keep tarps, plastic sheeting and a list of your insurer's claim contacts where you can reach them.

What should I check after a hurricane?

Safety first, then document everything. The claim steps follow NC Department of Insurance guidance.

Stay off the roof. Check from the ground and from inside the attic, with a flashlight, for daylight, wet decking or drips.
Photograph damage before any temporary repair, and keep receipts for tarps and other protective work (NC DOI).
Report the loss to your insurer promptly, and don't make permanent repairs until the insurer has inspected (NC DOI).
Call your agent or insurer before you sign a repair contract, and don't let a contractor deal with your insurer unless your agent approves (NC DOI).
Get more than one estimate, never sign a contract with blanks, and never pay in full up front (NC DOI).
Look for loose trim and flashing, dents from debris, and gutters pulled away from the fascia.

Hurricane roofing: questions, answered

What kind of roof holds up in a North Carolina hurricane?

One built as a system: a deck fastened with ring-shank nails, sealed deck seams or a secondary water barrier, secured edges and ridge, and a covering tested for the wind pressure where the house sits. No roof can be made immune to hurricanes. The IBHS FORTIFIED Roof standard is a detailed checklist for these details.

Is a metal roof good in a hurricane?

A well-installed metal roof with concealed fasteners and locked panel seams leaves wind little to grab. The details still decide the outcome: deck attachment, edge and ridge trim, and fastening to the manufacturer's specification. Interlock aluminum panels interlock on four sides with concealed fasteners, and wind resistance is warranted to 120 mph when installed to manufacturer specification.

What wind speed does a roof need to meet on the North Carolina coast?

The NC Residential Code sets a design wind speed by location, and some coastal areas are higher than 120 mph. Where the design wind speed is 130 mph or more, the State Fire Marshal's office says the code's prescriptive fastening table no longer applies and the structure needs wind analysis. Your county or city inspections department, or the engineer on the job, sets the requirement for your house.

What is a FORTIFIED Roof?

A roofing standard from the Insurance Institute for Business & Home Safety (IBHS). It calls for an enhanced deck-nailing pattern with ring-shank nails, a sealed roof deck, stronger edges and a roof covering rated for the site's wind pressure. A third party verifies each installation before IBHS designates it.

Do FORTIFIED roofs lower insurance premiums in North Carolina?

The NC Department of Insurance says a FORTIFIED Roof gives policyholders insurance credits that reduce their premiums. The amount depends on your insurer, where the house is and the level of FORTIFIED protection, so ask your agent for the figure in writing before you plan around it.

Are there grants for hurricane roofs in North Carolina?

The NC Insurance Underwriting Association has run Strengthen Your Roof grant programs for eligible NCIUA policyholders in coastal counties, for upgrading to a FORTIFIED Roof. Programs open and close and are first come, first served, so check the current terms with NCIUA before you sign a roofing contract.

Does the roof warranty cover hurricane damage?

No. The Guardian Lifetime Limited Material Warranty covers manufacturing defects in the material and finish, and it excludes damage from severe weather events. Storm damage is a homeowners-insurance matter, which is why the documents and photos from your installation are worth keeping.

When is hurricane season in North Carolina?

The Atlantic hurricane season runs from June 1 to November 30. The National Hurricane Center puts the peak on September 10, with most activity between mid-August and mid-October. Plan roof work and pre-season checks for spring or early summer when you can.

Do hurricanes damage roofs in Raleigh, Charlotte and the Triad?

Yes. Strong storms keep damaging winds well inland. Matthew brought gusts over 50 mph east of I-95 and 40 mph or more across much of the Piedmont, and Helene produced a 66 mph gust at Charlotte's airport. Falling trees are the most common cause of roof damage inland.

How do I get a hurricane-focused roof estimate?

Request an estimate and tell us where the house is and how exposed it is. We look at the deck, the edges and the trees, and the written, project-specific estimate covers what the inspection finds before work begins.
