Metal Roofing Guide: Types, Cost, Lifespan & Hail Facts

Metal roofing is a roof covering made from steel, aluminum, zinc, or copper, installed as long interlocking panels or as shingle-shaped tiles, instead of the individual overlapping shingles used on an asphalt shingles roof. It tends to make the most financial sense for homeowners who plan to stay in a house long-term, live somewhere hail or wind is a recurring problem, or want a reflective surface that cuts summer cooling bills.

The upfront price is the main trade-off: metal costs meaningfully more to install than shingles, so the decision usually comes down to how many years you expect to own the roof and how much storm exposure it will face. This guide walks through the three residential panel types, real cost and lifespan numbers, hail and wind performance, and what metal roofing does to a homeowners insurance premium. For a side-by-side breakdown against shingles, see metal roof vs. shingles, and for the full lineup of options, types of roofing materials.

Standing seam is the panel type most homeowners picture when they hear "metal roof." Panels run vertically from ridge to eave with raised interlocking seams, and the fasteners are hidden underneath those seams rather than driven through the panel face. Because nothing punctures the metal's weather surface, standing seam is the most watertight and generally the longest-lasting of the three types, and it's what most manufacturers rate for the highest wind speeds.

Exposed-fastener panels (sometimes called corrugated or R-panel) are screwed directly through the panel face into the deck, with the screw heads visible on the surface. They use thinner gauge steel, wider panel coverage, and a simpler installation process, which is why they cost meaningfully less than standing seam depending on gauge and paint system, according to Sheffield Metals' panel comparison. The trade-off is the rubber gaskets under each screw: they degrade with UV exposure and temperature swings, and as they wear, the fastener penetrations become the roof's most likely leak point.

Stone-coated steel panels are steel shingles or shakes coated with a layer of stone granules, built to visually mimic asphalt shingles, wood shakes, or tile while keeping steel's strength underneath. They install with an exposed-fastener-style overlap similar to shingles, which makes them a common choice for homeowners who want metal's durability without a look that reads as an obvious metal roof.

Metal roofing costs $14 to $41 per square foot installed depending on the metal, compared to $4 to $9 per square foot for asphalt shingles, according to This Old House's 2026 cost comparison. On a typical 2,000-square-foot home, that works out to roughly $53,811 for a metal roof versus $14,182 for an asphalt shingle roof — metal usually runs roughly three to four times more at installation.

Exposed-fastener panels sit at the low end of the metal range because of thinner gauge steel and simpler installation, while stone-coated steel and copper sit at the higher end. A roof replacement cost breakdown or the roof cost calculator can help price a specific roof against these ranges.

A well-maintained metal roof can last up to 100 years, according to This Old House, though real-world lifespan depends heavily on panel type. Standing seam roofs need less frequent maintenance than exposed-fastener roofs, which require regular fastener and gasket inspection as the rubber gaskets around each screw wear over time, per Sheffield Metals' panel guide.

At the high end, a Metal Construction Association service-life study of unpainted 55% aluminum-zinc-coated steel standing seam systems found flat-panel service life projections ranging from 60 to 375 years for the metal itself, with sealants conservatively projected at 60 years — the panel substrate essentially outlasts the building components around it. Asphalt shingles, by contrast, typically last 15 to 30 years. That lifespan gap is the core argument for metal despite the higher sticker price: a homeowner who replaces asphalt shingles two or three times over 60 years may spend close to what one metal roof costs upfront. See how long does a shingle roof last for the asphalt-side comparison.

Metal panels that carry a UL 2218 Class 4 rating — the highest impact-resistance classification — resist cracking and puncturing from hailstones better than standard asphalt shingles, though hail can still leave cosmetic dents in the metal surface without compromising the roof's waterproofing. Denting is more visible on thinner exposed-fastener panels and less visible on thicker standing seam gauges, but in either case a dent is typically cosmetic rather than a functional failure. For what hail actually does to a metal roof and how to document it, see can hail damage a metal roof and hail damage roof claim.

On wind, metal roofing systems are commonly rated well above the 90 mph gust design wind speed FEMA's Hurricane Ike recovery advisory uses as the threshold for high-wind installation practices, with many standing seam systems rated well beyond that threshold when properly installed. Installation quality drives wind performance more than the metal itself — panel fastening pattern, clip spacing, and edge detailing determine whether a roof rides out a storm or loses panels. A poorly installed metal roof in a 90 mph gust can fail the same way a poorly installed shingle roof does; see wind damage roof insurance claim for what that looks like from the claims side.

Reflective metal coatings can qualify as cool roof products, and the U.S. Department of Energy's Federal Energy Management Program lists ENERGY STAR-qualified cool roof products at a solar reflectance of roughly 0.5 after three years of weathering, compared to about 0.05 for a traditional dark roof surface — cool roofs can run up to 60°F cooler on the surface in summer. DOE's federal cost-effectiveness analysis found ENERGY STAR-qualified products pencil out if priced no more than $0.64 per square foot above a less efficient roof, with savings compounding over a 30-year product life. Reflective coatings matter most in hot, sunny climates on homes with limited attic insulation; in colder climates the same reflectivity can slightly increase winter heating costs by reducing beneficial solar heat gain.

Most metal roofing qualifies for Class 4 impact-resistance rating once it's tested to UL Standard 2218, and roofing materials tested and classified as Class 1 through 4 are eligible for impact-resistant roofing credits in states like Texas, where the discount amount is set individually by each insurance company rather than by a fixed statewide percentage, according to the Texas Department of Insurance. In practice, discount amounts vary widely by insurer and by how hail-prone the region is, since each company sets its own credit rather than following a fixed statewide rate.

Getting the discount isn't automatic — insurers generally require proof the specific product passed UL 2218 testing at that class rating, along with a contractor-completed installation form before the credit applies. It's worth asking an insurer directly what documentation they require before assuming a metal roof will lower a premium. For the shingle-side version of this same discount, see class 4 shingle insurance discount and are class 4 shingles worth it. Metal roofs also change how insurers handle depreciation and claims, since a longer-lived roof depreciates more slowly; see ACV vs. RCV roof insurance for how that plays out on a claim payout.

Standing seam makes sense when the budget allows for it and the roof needs to perform for decades with minimal maintenance — it's the best choice for wind-prone and coastal regions where hidden fasteners matter most. Exposed-fastener panels fit tighter budgets, outbuildings, or homeowners comfortable scheduling periodic gasket inspections, but they're not the panel to choose for a 40-year hold in a harsh climate. Stone-coated steel is worth considering when the goal is metal's durability with a shingle- or tile-like appearance, particularly in neighborhoods with HOA aesthetic requirements.

Whichever type is under consideration, get quotes from contractors who specifically install metal — the installation techniques, tools, and fastening patterns differ enough from shingle work that general roofing experience doesn't automatically transfer. See how to choose a roofing contractor and roofing quotes before signing anything.

If a metal roof has been through a hail or wind event, the claims process runs on the same fundamentals as any other roofing material: document the damage, understand what the policy actually covers, and don't assume the adjuster's first estimate is final. Dents that are purely cosmetic are sometimes excluded or handled differently than punctures or lost panels, so it's worth reviewing document roof damage insurance claim before an inspection happens. Checking a property's storm history against radar-estimated hail size with the storm history tool is also a useful first step before filing, since it shows what actually passed over a specific address rather than a general area.
