Stone coated steel roofing is a steel panel system coated with stone granules that gives you the structural performance of metal with the appearance of traditional asphalt shingles, tile, or shake. In Oklahoma’s climate, it solves a problem that neither standard asphalt nor standing seam metal fully addresses: outstanding hail and wind resistance at a mid-range price point, with an aesthetic that suits neighborhoods that might reject the industrial look of bare metal panels.
This guide covers what stone coated steel actually is (and what it is not), how it performs against Oklahoma’s specific weather patterns, realistic installed costs, which profiles work in which contexts, what the service page does not tell you about its limitations, and who this material genuinely suits versus who would be better served by standard asphalt or standing seam metal.

What Stone Coated Steel Roofing Actually Is
Stone coated steel panels are manufactured from galvanized or Galvalume steel, formed into a profile that mimics traditional roofing shapes, and then coated with an acrylic base layer and crushed stone granules. The granules are bonded with acrylic overglaze, creating a surface that visually resembles asphalt shingles, clay tile, or wood shake depending on the profile you choose.
The steel base is typically 26-gauge, though premium products use 24-gauge for greater dent resistance. The stone coating provides UV protection for the steel beneath and significantly reduces the characteristic noise of bare metal roofing during rain and hail events.
Manufacturers of stone coated steel products commonly seen in the Oklahoma market include DECRA, Gerard (owned by Fletcher Building), and Interlock. Each brand offers proprietary profiles and coating systems with varying warranty terms.
How Stone Coated Steel Performs in Oklahoma Weather
Hail Performance
Stone coated steel panels are rated to UL 2218 Class 4 impact resistance, the highest available rating for roofing materials. Under UL 2218 testing, Class 4 panels must withstand a 2-inch steel ball dropped from 20 feet without cracking or fracturing.
The important difference between stone coated steel and asphalt at this same rating is how each material fails under extreme impact. Class 4 asphalt shingles that sustain impact above their rated threshold crack, fracture, or lose mat integrity, creating a functional water entry point. Stone coated steel panels that sustain impact above their threshold dent. The stone coating may chip locally, but the underlying steel panel retains its waterproofing function.
For Oklahoma homeowners in Moore, Midwest City, and south OKC where 2-inch-plus hail events have occurred multiple times in the past decade, this failure mode difference is meaningful. A stone coated steel roof that dents in a golf ball hail event continues protecting the home. A Class 4 asphalt roof that sustains the same event may require full replacement.
Wind Performance
Stone coated steel panels interlock at their edges, which provides superior wind uplift resistance compared to asphalt shingles held by adhesive strips and nails. Most DECRA and Gerard products carry wind ratings of 120 to 155 mph, and the interlocking connection means individual panel loss is significantly less likely than individual shingle loss under high-wind conditions.
In Oklahoma, where straight-line winds from derechos and thunderstorm outflow frequently exceed 70 to 80 mph, and where tornadic activity can affect suburban neighborhoods, the interlocking panel system provides meaningfully better protection than shingle-based systems.
Heat and UV Performance
This is where stone coated steel shows a significant advantage over asphalt that is specific to Oklahoma’s climate. Oklahoma averages 230+ sunny days annually and UV index values that accelerate asphalt binder degradation. The asphalt granules that protect shingles gradually loosen as the binder beneath them becomes brittle under UV exposure, this is why Oklahoma asphalt roofs often reach the end of their practical life at 18 to 22 years rather than the manufacturer’s rated 25 to 30 years.
Stone coated steel does not degrade under UV in the same way. The steel substrate is not UV-sensitive, and the acrylic overglaze that bonds the stone coating is formulated for long-term UV resistance. The practical implication is that a stone coated steel roof installed in Oklahoma in 2026 should be performing at essentially the same level in 2046 without the accelerated UV aging that shortens asphalt lifespan in the Oklahoma climate.
What Stone Coated Steel Does Not Handle as Well
Every material has trade-offs that honest evaluation requires acknowledging.
Repairability: If a stone coated steel panel is significantly damaged, by a large falling limb rather than hail, for instance, repairing it requires sourcing a matching panel from the same manufacturer and profile line. If that product is discontinued, finding an exact match can be difficult. Standard asphalt shingles are universally available and any contractor can source matching material. This is a real practical concern for long-term ownership.
Cost: Stone coated steel costs significantly more per square than asphalt, typically $800 to $1,400 installed per square versus $450 to $850 for Class 4 asphalt. The longevity advantage justifies this for the right homeowner, but for someone who plans to sell within 5 to 7 years, the premium may not be recovered in resale value.
Installation expertise: Stone coated steel requires installers trained and certified by the specific manufacturer. Unlike asphalt, which any licensed roofer can install correctly, stone coated steel has specific fastening patterns, batten requirements on some profiles, and underlayment specifications that untrained installers frequently get wrong. Incorrect installation voids the warranty and reduces the panels’ wind performance.
Stone Coated Steel Profiles Available in Oklahoma
| Profile | Resembles | Best Context | Notes |
| Stone coated shingle | Architectural asphalt shingles | Most Oklahoma residential homes | Most common, suits traditional neighborhood aesthetics |
| Stone coated tile | Mediterranean / clay tile | Higher-value homes, specific architectural styles | Heavier appearance, requires appropriate home design |
| Stone coated shake | Cedar wood shake | Craftsman, cottage, rural-style homes | Less common in OKC metro, strong visual impact |
| Stone coated slate | Natural slate | Premium homes, historical renovation | Least common, highest visual impact, confirm availability |
The shingle profile is by far the most commonly installed in the Oklahoma City metro because it suits the broadest range of home styles and satisfies most HOA aesthetic requirements without requiring special approval. If your neighborhood has deed restrictions on roofing material appearance, confirm that stone coated steel in the shingle profile is permissible before ordering.
Installed Cost of Stone Coated Steel in Oklahoma
| Cost Component | Typical Range | Notes |
| Material (per square, 100 sq ft) | $400 to $900 | Varies by manufacturer and profile |
| Labor (per square) | $300 to $500 | Higher than asphalt due to panel handling and interlocking |
| Tear-off and disposal | $1,000 to $2,500 | Full removal of existing system required |
| Underlayment upgrade | $500 to $1,500 | Synthetic underlayment required under most manufacturer specs |
| Typical total, 25-square home | $18,000 to $35,000 | Standard single-story, moderate pitch |
| Typical total, 30-square home | $22,000 to $42,000 | Larger home or complex roofline |
These ranges reflect 2026 Oklahoma market rates from licensed installers. Significantly lower quotes for stone coated steel most often reflect either a lower-gauge product, an installer without manufacturer certification, or exclusion of tear-off and underlayment from the scope. Confirm exactly what is included in any estimate you receive.
Does Insurance Cover Stone Coated Steel in Oklahoma?
This question has a nuanced answer that depends on your specific insurer and policy terms.
For storm-funded replacements: Oklahoma insurers will pay to replace a storm-damaged asphalt roof with asphalt. If you want to upgrade to stone coated steel, the insurer typically pays the asphalt replacement value and you pay the upgrade difference out of pocket. This is a common scenario and often the most cost-effective way to access stone coated steel, the insurance payment covers the base replacement, and you contribute the upgrade premium.
For hail damage claims on existing stone coated steel: Most Oklahoma policies cover storm damage to stone coated steel roofing. However, cosmetic damage exclusions, which exclude coverage for denting that does not affect waterproofing, are becoming more common. Given that denting without waterproofing failure is the typical hail damage outcome on stone coated steel, review your policy terms carefully or confirm with your agent before assuming hail damage will trigger a covered claim.
For new installations: Installing stone coated steel may qualify for premium discounts similar to Class 4 asphalt, though the discount structure varies by insurer. Confirm with your agent.

Is Stone Coated Steel Right for Your Oklahoma Home?
Stone coated steel makes the most financial sense when four conditions align:
- Long-term ownership. You plan to stay in the home for 15+ years, allowing the lifespan advantage to pay back the higher upfront cost.
- Hail-prone location. Your neighborhood has a documented history of severe hail events that have already shortened or ended previous asphalt roof lifespans.
- Aesthetic constraints. Standing seam metal’s industrial appearance does not fit your neighborhood or HOA requirements, but you want metal’s performance.
- Mid-range budget. You can absorb the upgrade cost above an insurance payout or above a standard asphalt replacement, but a full standing seam metal installation is outside budget.
It is less suitable when you plan to sell within 5 to 7 years (the premium is difficult to recover in resale), when budget is the primary constraint (Class 4 asphalt delivers excellent value at lower cost), or when your insurer’s cosmetic exclusion provisions would mean hail denting events are not covered (removing a key financial advantage).

Frequently Asked Questions
How long does stone coated steel roofing last in Oklahoma?
Most manufacturers rate stone coated steel products at 40 to 50 years in residential applications. In Oklahoma’s climate, this lifespan is not meaningfully shortened by UV exposure or hail the way asphalt lifespans are, making it a reliable 40+ year material under normal conditions.
Is stone coated steel louder than asphalt during rain or hail in Oklahoma?
Not significantly. The stone coating absorbs impact and reduces the metallic resonance common with bare metal panels. With standard decking and insulation, stone coated steel is comparable to asphalt in interior noise levels during rain events. Hail on stone coated steel is audible but not dramatically louder than on asphalt.
Does stone coated steel roofing increase home value in Oklahoma?
Yes, particularly on mid-to-higher value homes. The material is increasingly recognized by buyers and appraisers as a long-life premium upgrade. The value addition is most significant on homes above $250,000 and in communities like Edmond, Yukon, and Mustang where buyer expectations skew toward quality materials.
Can stone coated steel be installed over existing asphalt shingles?
Technically possible but not recommended by most manufacturers and not advisable for Oklahoma’s climate. Installing over existing shingles traps moisture, prevents decking inspection, and voids most warranties. Full tear-off is standard practice for quality stone coated steel installations.
What is the difference between stone coated steel and standard metal roofing?
Standard metal roofing uses bare painted steel or aluminum panels in standing seam or exposed fastener configurations. Stone coated steel uses the same steel substrate but adds an acrylic base layer and stone granule coating that changes the appearance to resemble asphalt shingles, tile, or shake. Both offer metal’s longevity and weather resistance. Stone coated steel offers greater aesthetic flexibility. Standing seam metal offers the lowest maintenance over time.
