Metal Roofing

Metal roofing done properly comes down to four decisions: gauge, panel length, closures and fasteners. We roll-form our own panels in Farmville, NC, so here is a straight explanation of each โ€” including where spending more is pointless.

Why metal instead of shingles

A metal roof lasts several times longer than an asphalt shingle roof, sheds snow and debris rather than holding them, and does not lose granules into your gutters every storm. It costs more up front. Over a thirty-year horizon in the Southeast the comparison usually favours metal, but if you are selling the house in three years, shingles are the rational financial choice and we will say so.

The four decisions that actually matter

Gauge: 29 is standard and correct for most roofs; 26 earns its price on wide purlin spacing, hail country, or roofs you walk on. Panel length: cut-to-length means one continuous piece from ridge to eave, eliminating horizontal laps entirely. Closures: foam pieces filling the rib profile at ridge and eave, without which your peak is open along its whole length. Fasteners: painted-head screws with bonded washers, sized to your framing. Everything else is preference.

What actually fails, and when

Almost never the panel. The sequence is: washers perish under UV, screws back out with thermal cycling, water enters at fastener holes; or cheap foam closures compress permanently and wind-driven rain tracks under the ribs. Both happen years before the steel gives up. That is why we push customers toward better fasteners rather than heavier gauge โ€” it is where the money changes the outcome.

Over shingles, or tear off first

Going over existing shingles saves tear-off labour and landfill fees, and is common across the Southeast. It requires a sound deck, longer fasteners to reach solid framing, and a check on how many layers are already up there โ€” most jurisdictions cap it. Steel follows the plane it is fixed to, so a wavy deck stays wavy. If the deck is soft, tear off.

Common Questions

How long does a metal roof last?

Several decades with a sound coating and quality fasteners โ€” considerably longer than asphalt shingles. The limiting factor is almost always fasteners and closures rather than the panels, which is why those components are worth specifying properly.

Is a metal roof worth the extra cost?

Over a long horizon in the Southeast, usually yes โ€” longer service life, better weather shedding, no granule loss. If you expect to sell within a few years you may not recover the premium, and we would rather tell you that than take the order.

Are metal roofs noisy in the rain?

Far less than people expect on a roof over decking and insulation โ€” the myth comes from bare panels over open purlins on barns. On a house with a deck beneath, the difference from shingles is minor.

Do metal roofs attract lightning?

No. Metal does not attract lightning, and being non-combustible it is arguably safer if struck. This is one of the most persistent myths in roofing.

What gauge metal roofing should I use?

29-gauge for most residential and agricultural roofs โ€” it is the industry standard. Step up to 26-gauge for wide purlin spacing, hail-prone areas, or roofs walked on regularly. Call (252) 375-3651 and we will tell you which applies rather than defaulting to the upsell.
