North Carolina metal roofing for storms, heat and salt air.Interlock® aluminum, installed by Metal Roof NC.

Metal Roof NC, an authorized Interlock aluminum roofing dealer based in Raleigh. Interlock Roofing manufactures the panels; Metal Roof NC sells and installs them for homeowners in the Triangle, the Charlotte area, the Triad and Piedmont, and the North Carolina coast.

An Interlock roof is a strong choice for wind, though no roof is immune to hurricane damage. The panels lock on all four sides with concealed fasteners, and wind resistance is warranted to 120 mph when installed to manufacturer specification. Parts of the North Carolina coast are designed for higher wind speeds, so the permit office, and an engineer where one is required, sets what your house needs.

No. Aluminum does not rust, because there is no steel in it; a thin oxide film protects the metal, which makes it corrosion-resistant in salt air. That is the main reason aluminum suits homes in Wilmington, New Bern, Morehead City, Jacksonville and Beaufort.

Sometimes. A single layer of asphalt shingles may be roofed over only if an inspection finds it suitable and the local code allows it. Cedar shingles and shakes, concrete or clay tile and natural slate always come off first. We tell you which applies at the estimate.

Two. The Guardian Lifetime Limited Material Warranty from Interlock Roofing covers material and finish for the original purchaser while they own the home, transfers once (the second owner is covered to 50 years from substantial completion) and excludes workmanship; the Alunar® coating is warranted 30 years. The installation is covered by the Metal Roof NC 5-Year Labor Warranty for five years.

Metal Roof NC's rule of thumb is that an Interlock aluminum roof typically costs about 2.5 to 3 times a traditional asphalt-shingle roof. Prices vary job to job with roof size, pitch, tear-off and other conditions, so an on-site estimate is required for an accurate price.

Yes. Financing is available through Service Finance for qualified homeowners, subject to lender approval and terms. Applying does not require choosing a roofing system first.

Often. Many subdivisions in the Triangle and around Charlotte have architectural review rules, so check your covenants and get approval before you sign. Slate, Cedar Shingle and Shake keep a traditional look, and we can supply samples and product documents for the application.
