DECRA is a stone-coated metal roofing system: aluminum-zinc coated steel panels topped with acrylic-bonded stone granules, priced at roughly $14 to $22 per square foot installed in 2026, or about $35,000 to $55,000 on a typical 2,400 square foot roof. It mimics shake, shingle, or barrel-tile looks, carries a Class A fire rating and Class 4 impact rating, and lasts 40 to 50-plus years. DECRA is one brand in the stone-coated steel category alongside Gerard, Metro, and Unified Steel (formerly Boral).
What is DECRA stone-coated metal roofing?
DECRA is a stone-coated steel roofing product built from a G90 aluminum-zinc alloy coated steel base, a bonding acrylic layer, and a top surface of crushed natural stone granules. The stone hides the metal look, dampens rain noise, and shields the coating from UV. It reads as tile, shake, or architectural shingle from the street while weighing a fraction of what real tile or slate weighs.
The category is often called stone-coated steel or decorative metal roofing. DECRA (owned by Westlake Royal Building Products) is the brand that popularized it in the U.S. market in the 1950s. Because the granular surface and profile stamping do the visual work, a stone-coated panel gives the curb appeal of a heavy roof without the structural load.
The layers that make up a stone-coated steel panel
A stone-coated steel roof is a multi-layer system, and each layer does a specific job. Understanding the stack explains both the durability and the price. Most competitor guides skip this and quote a number without saying what you are paying for.
- Steel core: 26-gauge structural steel, stamped into the profile shape (shake, tile, or shingle).
- Aluminum-zinc (Galvalume) coating: a corrosion barrier bonded to the steel, rated for decades of exposure.
- Acrylic base coat: primes the surface and bonds the granules.
- Stone granule layer: crushed natural stone or ceramic-coated granules that provide color, texture, and UV protection.
- Acrylic overglaze: a clear top seal that locks the granules and adds weather resistance.
DECRA profiles and product lines
DECRA sells five main profiles, each imitating a traditional roof style. The profile you pick changes the look, the install method, and the price. Shake and shingle profiles run lower; barrel-tile and Villa profiles carry more steel and cost more per square foot.
| DECRA product line | Look it mimics | Install method | Typical installed cost/sq ft |
|---|---|---|---|
| DECRA Shingle XD | Architectural asphalt shingle | Direct-to-deck, hidden fastener | $14 to $18 |
| DECRA Shake XD | Cedar shake | Direct-to-deck, hidden fastener | $15 to $19 |
| DECRA Tile | Spanish / Mediterranean barrel tile | Batten-mounted | $16 to $21 |
| DECRA Villa Tile | Low-profile clay tile | Batten-mounted | $16 to $22 |
| DECRA Shake | Split cedar shake, deeper profile | Batten-mounted | $16 to $21 |
The XD lines use a batten-less, direct-to-deck system with a hidden fastening clip, which speeds installation and lowers labor. The tile and traditional shake profiles usually mount on a batten grid, which adds material and labor but delivers a deeper, more authentic shadow line.
How much does a DECRA roof cost in 2026?
A DECRA stone-coated metal roof costs roughly $14 to $22 per square foot installed in 2026, which works out to about $1,400 to $2,200 per roofing square (100 square feet). On a typical 2,400 square foot roof, expect $35,000 to $55,000 total. Material alone runs $450 to $650 per square; the rest is labor, tear-off, underlayment, trim, and accessories.
Price depends on profile (tile costs more than shingle), roof pitch and complexity, tear-off of the old roof, and regional labor rates. Stone-coated steel sits above standard corrugated or exposed-fastener metal and lands near premium standing seam. For the wider category math, see our metal roof cost breakdown.
| Cost component | Typical range (per square, 100 sq ft) |
|---|---|
| Stone-coated steel material | $450 to $650 |
| Labor (install) | $550 to $1,000 |
| Tear-off of existing roof | $100 to $250 |
| Underlayment and accessories | $150 to $300 |
| Installed total | $1,400 to $2,200 |
DECRA vs Gerard vs Metro vs Unified Steel
DECRA is one of four major stone-coated steel brands sold in the U.S. All four use the same basic Galvalume-steel-plus-stone construction, so the differences come down to profile selection, fastening system, warranty terms, and price. Here is how they compare on the points buyers actually weigh.
| Brand | Owner | Profiles offered | Installed cost/sq ft | Notable feature |
|---|---|---|---|---|
| DECRA | Westlake Royal | Shingle, shake, tile, Villa | $14 to $22 | Batten-less XD lines, hidden fastener |
| Gerard | Roser / TAMKO distribution | Shake, tile, shingle | $13 to $20 | Long track record, canopy interlock |
| Metro (Metro Roof Products) | Metro Roof Products | Shake, shingle, tile, slate | $12 to $19 | Slate-look profile, lighter panels |
| Unified Steel (ex-Boral) | Westlake Royal | Pine-Crest shake, Granite-Ridge shingle, Barrel-Vault tile | $14 to $20 | Now under same parent as DECRA |
Treat brand choice as roughly a wash on core performance. Local installer availability and who honors the warranty in your region often matter more than the brand name. Note that DECRA and Unified Steel now share the same parent company, Westlake Royal Building Products.
Pros and cons of stone-coated metal roofing
Stone-coated metal roofing trades a high upfront cost for a very long service life and strong weather resistance. It suits homeowners who plan to stay in the house, live in a fire or hail zone, or want a tile or shake look without the structural weight. It is a weaker fit if the budget is tight or the roof is being flipped short-term.
Pros
- Lifespan of 40 to 50-plus years, often with a limited lifetime or 50-year warranty.
- Class A fire rating and Class 4 impact rating, the top tiers, which can qualify for insurance discounts. See our guide to the Class 4 insurance discount.
- Wind rated to 120 to 160-plus mph when installed to spec, strong in hurricane and high-wind zones.
- Light weight, around 1.5 pounds per square foot, roughly a quarter of concrete tile, so most structures need no reinforcement.
- Energy reflectivity, the granule surface reflects solar heat and can cut cooling load in warm climates.
- Curb appeal, delivers a tile, shake, or shingle look that reads as a premium roof.
Cons
- High upfront cost, two to four times the price of a standard asphalt shingle roof.
- Installer expertise required, fewer crews are trained on stone-coated systems, and a bad install voids the warranty.
- Denting is possible from very large hail or falling limbs, though the granule layer hides minor marks.
- Granule loss over decades, similar to asphalt shingles, some granule shedding occurs with age.
- Batten-mounted tile profiles add weight and cost versus the direct-to-deck shingle lines.
How long does a DECRA roof last, and how does it compare?
A properly installed DECRA stone-coated steel roof lasts 40 to 50-plus years, outliving asphalt shingles (15 to 30 years) and rivaling standing seam metal (40 to 70 years). The steel core resists rot and insects, and the stone surface resists UV degradation that ages asphalt. Manufacturer warranties commonly run 50 years or a limited lifetime term.
Field-measured lifespans often differ from marketing claims, which is why service life should be checked against real data rather than brochure numbers. Compare category-by-category figures in our 2026 roofing material lifespan report, and see where stone-coated fits among all the options in our overview of metal roofing types.
When stone-coated metal is the wrong choice
Stone-coated metal is not always the right pick. If the budget cannot absorb a premium roof, a mid-tier architectural asphalt shingle delivers 25 to 30 years for a fraction of the cost. If you want a modern, sleek metal look with concealed clips and clean lines, standing seam is the better match; stone-coated is designed to look like tile or shake, not like metal.
Stone-coated also makes less sense on a home you plan to sell within a few years, since you will not recover the full premium at resale. For a direct head-to-head on the most common trade-off, read our metal vs asphalt shingle comparison.
Frequently asked questions
Is a DECRA metal roof worth it?
A DECRA roof can be worth it for homeowners who plan to stay long term or live in a fire, hail, or high-wind zone. Its 40 to 50-plus year lifespan spreads the high upfront cost across decades, and Class A fire plus Class 4 impact ratings may earn insurance discounts. It is less worthwhile on a short-term hold or a tight budget, where architectural asphalt shingles make more financial sense.
How much does a DECRA roof cost per square foot?
DECRA stone-coated metal roofing costs about $14 to $22 per square foot installed in 2026, depending on the profile and roof complexity. Shingle and shake XD lines sit at the lower end near $14 to $18, while batten-mounted tile and Villa profiles run $16 to $22. On a 2,400 square foot roof, total cost typically lands between $35,000 and $55,000 including tear-off and accessories.
Does stone-coated metal roofing dent?
Stone-coated steel can dent from very large hail or heavy falling branches, but it holds a Class 4 impact rating, the highest tier, which means it resists the impacts that crack tile or bruise asphalt. The stone granule surface also hides minor marks that would show on smooth metal. Most homeowners see no visible denting from routine weather.
Is a DECRA roof noisy in the rain?
A DECRA roof is quieter than exposed smooth metal because the stone granule layer and the solid decking beneath absorb sound. It is not silent, and heavy rain or hail can be more audible than on asphalt shingles. Adding a slip-sheet underlayment or extra attic insulation reduces noise further in most installs.
Can you install stone-coated metal over an existing roof?
Stone-coated metal can sometimes install over one existing layer of asphalt shingles where local code allows, since the panels are light at about 1.5 pounds per square foot. Many roofers still recommend a full tear-off to inspect the decking and install fresh underlayment, which protects the warranty. Confirm the manufacturer and code requirements before choosing an overlay.
How long does stone-coated steel roofing last?
Stone-coated steel roofing lasts 40 to 50-plus years when installed correctly, and most brands back it with a 50-year or limited lifetime warranty. The Galvalume-coated steel resists corrosion and the stone surface resists UV breakdown, so it outlasts asphalt shingles by decades. Actual service life depends on install quality, climate, and maintenance.
