How Often Do Hurricanes Hit This Coast?

Often. Irene made landfall near Cape Lookout on August 27, 2011, and Florence came ashore near Wrightsville Beach on September 14, 2018. Florence's peak gust at Wilmington International was 105 mph, and inundation along the Neuse River near New Bern reached up to 11 feet above ground level, according to NWS and National Hurricane Center reports.

Why Aluminum Near Salt Water?

Aluminum does not rust. Steel roofing and steel fasteners near salt spray depend on their coatings to hold up, and once the coating is breached, rust starts. Interlock panels are about 98% heavy-gauge aluminum and are corrosion-resistant in salt air, which is why the material makes sense this close to the ocean.

What Wind Rating Does the Code Expect?

The North Carolina Residential Code assigns every location an ultimate design wind speed in Table R301.2(5), and those speeds rise toward the coast. Where the design speed is 130 mph or more, the NC Department of Insurance requires a licensed engineer's structural analysis of framing fasteners. Interlock's warranted wind resistance is 120 mph when installed to manufacturer specification. Your permit office or engineer sets the requirement for your specific house, and the roof has to be installed to meet it.

How Wet Is It?

Very. NOAA's 1991-2020 normals put annual precipitation at 60.15 inches at Wilmington, 55.68 inches at Beaufort and 53.01 inches at New Bern, before counting hurricane rainfall.

What Should Coastal Owners Ask Before Signing?

How the roof will be attached to meet your home's design wind speed, which underlayment and flashing details go at eaves and rakes, and who pulls the permit. Also ask how the warranty works if you sell: the Guardian Lifetime Limited Material Warranty transfers once, covering the second owner to 50 years from substantial completion.
