Steel underneath,stone on the surface.
Unified Steel forms steel panels into tile, slate, shake, and shingle profiles, then bonds a granulated stone finish over the top. The result reads like traditional roofing from the curb and carries a Class 4 impact rating with a 50-year warranty.
The short answer
Is stone-coated steel a good roof for Omaha hail?
Yes, and it is one of the strongest cases for the material. The panels carry a UL 2218 Class 4 impact rating because the steel core absorbs a hail strike without cracking, which is how clay tile, concrete tile, and natural slate fail. The stone coating dampens rain and hail noise, the interlocking panels are wind-tested to 120 mph, and the whole system weighs about a third of what concrete tile does, so it goes on standard framing. A Class 4 roof can also earn an insurance premium discount of 10-30% depending on your carrier, so ask your agent what your policy offers.
The profiles
Four looks, one panel system
Every profile shares the same steel core, stone coating, ratings, and warranty. The choice is about which traditional material you want the roof to read as.
| Profile | The look | Worth knowing |
|---|---|---|
| Spanish Tile | Traditional barrel tile with a deep curve | The clay-tile look without clay's weight or fragility |
| Slate | Dimensional slate with a textured face | The stone coating gives it natural color variation and depth |
| Shake | Cedar shake texture and shadow detail | Wood appearance with steel durability, in multiple colors |
| Shingle | Classic architectural shingle lines | The lightest profile, with the same ratings as the rest |
The system
Interlocking panels, no exposed fasteners.
The panels lock into each other and overlap, and the fasteners sit concealed under the panel above, so there are no screw heads exposed to weather on the roof surface. That interlock is what earns the 120 mph wind-tested rating, and the overlapped seams shed wind-driven rain, which matters when the storms that bring hail here bring sideways rain with it. The stone coating on top adds UV protection and keeps the color stable over the years.
Hail
Steel takes the hit that breaks tile.
Hail cracks clay, shatters slate, and bruises asphalt. Steel flexes and springs back, which is how these panels pass the UL 2218 Class 4 test against 2-inch impacts without losing weathertightness. A hard enough storm can mark the stone coating, but a cosmetic scuff is a different outcome than a cracked tile letting water into the deck. If hail is the reason you are shopping for a new roof, this material removes most of what hail can do to one.
The details
Metal lives or dies at the flashing.
Valleys, chimneys, and wall intersections take different techniques on a metal roof than on a shingle roof, and the panel layout has to leave room for the expansion and contraction that comes with our temperature swings. This is where 25 years in the trades earns its keep, because the panel field is the easy part and the transitions are where a metal roof is won or lost. If you are weighing this against a shingle roof replacement, the flashing detail is a fair thing to ask any contractor about.
Up close
The profile holds up at arm's length.
Stone-coated steel is one of the few metal roofs that looks better the closer you get. The granule surface carries real texture, and the formed profile throws the same shadow lines as the material it echoes.
Who's behind it
Built on a builder's standard.
Tailwind Roofing is led by David Nelan, with 25+ years in the trades, two decades of it building and finishing exteriors across the Omaha metro, and a Class B contractor's license. Metal roofing rewards the installer who sweats the transitions, and every Unified Steel job is held to the standard he has worked to since 2003.
Questions
Common questions about Unified Steel roofing
Will a Unified Steel roof dent from hail?
The panels carry a UL 2218 Class 4 impact rating, the highest hail rating there is, and the steel core absorbs a 2-inch hail strike without permanent deformation. A severe storm can scuff the stone coating, but the steel underneath keeps the roof weathertight, which is the part that matters. The Class 4 rating can also earn an insurance premium discount of 10-30% depending on your carrier.
Is a metal roof loud when it rains?
Not this kind. The granulated stone surface dampens impact sound, and the panels go over a solid deck rather than open framing, so rain noise ends up comparable to an asphalt shingle roof. The barn-roof drumming people picture comes from bare metal over open purlins, which is a different construction entirely.
How does Unified Steel compare to concrete or clay tile?
You get the tile look at about one-third the weight of concrete and less than half the weight of clay, so there is no structural reinforcement to pay for. Steel does not crack under hail or foot traffic the way clay and concrete do, the panels install faster than setting individual tiles, and the warranty runs 50 years where many tile products cover 20 to 30.
How long does installation take, and can it happen in cold weather?
Most homes take 2 to 4 days. Steel is not temperature-sensitive the way asphalt and synthetic tiles are, so it installs across a wider stretch of the calendar, including cold months when other materials have to wait. Complex rooflines with valleys, hips, and penetrations add time, and weather can still shift a schedule.
What maintenance does a stone-coated steel roof need?
Very little. An annual look at the fasteners, flashing, and panels covers it, along with keeping valleys and gutters clear. The stone coating sheds some granules early on and then stabilizes, and if a panel ever takes damage, it can be swapped without disturbing the rest of the roof.
