What Is Stone Coated Metal Roofing?

Stone coated metal roofing consists of a metal substrate—typically steel—covered with an anti-corrosion layer, an acrylic or epoxy adhesive, natural stone granules, and a protective topcoat. This construction creates a product that mimics shingles, tiles, or slate while retaining the strength and longevity of metal. Stone chips provide aesthetic variety and UV protection, while the metal core delivers structural durability.

Key Benefits

Stone coated metal roofing combines visual appeal with practical performance. Primary benefits include exceptional wind and impact resistance, long service life, resistance to rot and insect damage, and lower long-term maintenance compared with asphalt shingles.

• Longevity: Many products offer 30–50 year warranties and can last 50+ years in favorable conditions.
• Weather Resistance: Superior performance in high winds, hail, and heavy rain when properly installed.
• Energy Efficiency: Reflective coatings and air gap installation can reduce attic heat gain and cooling costs.
• Fire Resistance: Most stone-coated metal roofs are Class A fire rated.

Common Drawbacks

Stone coated metal roofing has advantages but also limitations to consider. Upfront cost and weight (heavier than some metal panels) are primary drawbacks. While lighter than concrete tile, stone coated systems may be heavier than standing seam metal and more expensive than asphalt shingle options. Proper installation is critical to avoid leaks and warranty issues.

Leading Brands And Product Reviews

Gerard Roofing

Gerard is recognized for its stone-coated steel tiles resembling shake and clay profiles. Strengths include a proven track record in severe weather and long warranties; common praise notes durability and curb appeal. Some reviewers cite higher cost and limited local installer availability as downsides.

Decra

Decra emphasizes impact resistance and wind performance with profiles that replicate slate and shake. Consumer reviews highlight excellent hail resistance and a solid warranty experience. Pricing can be premium, and color matching over time depends on local climate and UV exposure.

Metrotile

Metrotile offers cost-competitive stone coated metal tiles with varied profiles. Users report good value and performance; professional installation quality affects the roof’s long-term leak resistance. Availability varies across the U.S., and warranty terms differ by distributor.

Tilcor

Tilcor provides multiple profiles and emphasizes light weight compared to traditional tiles. Reviewers appreciate the design choices and longevity; some note that installation complexity can raise labor costs. Warranty claim processes depend on local dealers.

Performance Factors To Check In Reviews

When reading stone coated metal roofing reviews, focus on these performance attributes to separate marketing claims from real-world outcomes. Important factors include wind uplift rating, hail resistance class, corrosion protection, coating type, and actual owner reports on leaks and color retention.

• Wind Rating: Look for ASTM or UL wind uplift test results, especially in coastal or tornado-prone areas.
• Hail Resistance: Check impact test ratings; hail performance is important in the Plains and Mountain West.
• Coatings & Sealants: Quality of primer, stone adhesive, and topcoat determine color retention and longevity.
• Attachment System: Exposed vs. concealed fasteners affect appearance and potential for water intrusion.

Cost Breakdown And Value Analysis

Installed cost varies widely depending on product, roof complexity, and region. Stone coated metal roofing typically costs two to three times more than basic asphalt shingles but less than many clay or slate installations. Homeowners should consider lifecycle value: lower maintenance, longer warranty, and possible energy savings often offset higher initial expense.

Component	Typical Cost Range
Material Per Sq Ft	$5–$10
Installation Labor Per Sq Ft	$2–$5
Total Installed Per Sq Ft	$7–$15

Installation Tips From Reviews

Installation quality is the most common factor distinguishing positive reviews from negative ones. Choose certified installers with stone coated metal experience and verify that they follow manufacturer guidelines for underlayment, fasteners, and flashings.

1. Underlayment: Use high-quality synthetic or felt underlayment recommended by the manufacturer for added moisture control.
2. Flashing Details: Properly flash valleys, chimneys, and roof penetrations to prevent leaks.
3. Fastener Torque & Placement: Avoid over- or under-driving screws; manufacturer specs matter for warranty compliance.
4. Ventilation: Maintain attic ventilation to prevent heat buildup and condensation that can degrade warranties.

Maintenance And Long-Term Care

Stone coated metal roofs are comparatively low maintenance, but routine inspections help preserve performance. Annual checks for loose fasteners, damaged flashings, and debris buildup will extend service life and simplify warranty claims.

• Clean gutters and downspouts regularly to prevent water backup.
• Remove debris and trim overhanging branches to minimize surface abrasion and moss growth.
• Address localized stone or coating damage promptly with manufacturer-approved touch-up products.

Warranty And Claims: What Reviews Reveal

Warranties range from 30 to 50 years and may separately cover paint and stone adhesion. Positive reviews often highlight straightforward, responsive warranty handling; negative reviews typically involve improper installation voiding coverage. Verify transferability terms and pro-rated vs. non-prorated coverage before purchase.

Energy Efficiency And Insurance Considerations

Stone coated metal roofs can improve energy performance through reflective coatings and attic airspaces, reducing cooling loads in warm climates. Some insurers offer discounts for impact-resistant or Class A fire-rated roofs; homeowners should request quotes before installation.

How To Read Consumer Reviews Effectively

Not all reviews are equally informative. Prioritize reviews that include specifics about climate, roof age, installer name, and the exact issue addressed. Look for patterns across multiple reviews rather than isolated extreme opinions.

• Check professional reviews from industry groups and building science sources for test data.
• Use regional groups to assess local performance and installer reputations.
• Ask manufacturers for references of recent installations in similar climates.

Buying Checklist: Questions To Ask Before You Commit

Make purchase decisions using a consistent checklist. Essential questions cover warranty specifics, local installer certification, product test data, color retention expectations, and expected delivery dates.

• What is the exact warranty term and what does it cover?
• Is the installer certified by the manufacturer and insured?
• Are there documented wind and hail test results for the specific product profile?
• How are warranty claims handled locally, and are there service centers nearby?

Frequently Asked Questions

Will Stone Coated Metal Roofing Rust?

Properly manufactured stone coated metal roofing uses corrosion-resistant coatings and galvanized or galvalume steel. Rust is uncommon when the coating system and paint remain intact; scratches and exposed edges should be treated to prevent corrosion.

How Loud Is Metal Roofing In Rain Or Hail?

Stone coated metal roofs are laid over substrate and underlayment that dampen sound. Most homeowners report no significant noise increase compared to asphalt shingles; impact sound from hail is often less noticeable than solid tile due to the metal substrate’s resilience.

Can Stone Coated Metal Be Installed Over Existing Shingles?

In many jurisdictions, stone coated metal can be installed over existing roofing if local codes permit and roof structure supports the load. Verification with local building officials and the manufacturer is essential to maintain warranty and code compliance.

Summary Of Review Consensus

Across consumer and professional reviews, stone coated metal roofing is consistently praised for longevity, weather resilience, and aesthetic versatility. Top concerns focus on proper installation, up-front cost, and availability of qualified installers in some regions. For homeowners prioritizing durability and curb appeal, stone coated metal roofing represents a strong long-term value when product choice and installation quality align.

Next Steps For Homeowners

Homeowners should obtain multiple bids from certified installers, request product data sheets and test reports, and review local references. Comparing total installed costs, warranty details, and expected energy or insurance savings will clarify the best option for each property.
