Overview
What Is Mediterranean Metal Tile Roofing?
Interlock® Mediterranean Metal Tile Roofing delivers the curved barrel-tile profile of traditional clay roofing at 70 lbs per square — approximately 96% lighter than concrete or clay tile — enabling significant structural cost savings on new construction and making retrofit over existing roofing feasible without truss modification. The 0.028" aluminum hidden fastener panel features an 18" horizontal exposure, 15" tile step, and 1.2" profile height. Rated Class 4 under UL 2218, warranted to 120 mph wind resistance, and backed by the Guardian Lifetime Limited Non-Prorated Material Warranty, it carries ICC-ES ESR-1790 and Florida Product Approval FL7263.
Conventional clay and concrete tile at 900–1,200 lbs per square requires engineered truss systems and makes retrofit structurally impractical without significant reinforcement expenditure. At 70 lbs per square, Interlock Mediterranean Metal Tile resolves both: new builds specify standard residential truss loads; retrofits install over existing roofing with optional strapping — no structural modification required. Concealed fasteners preserve authentic tile aesthetics while providing full thermal expansion clearance. For projects in Florida, the Gulf Coast, the Southwest, and California, it delivers the region's expected roof profile at a lifecycle cost clay and concrete cannot approach.
Why Homeowners Choose Mediterranean Metal Tile Roofing Over Asphalt
In insurance markets where hail-susceptible clay tile carries elevated premium classifications, Interlock Mediterranean Metal Tile's Class 4 UL 2218 rating and ductile aluminum construction represent documentable risk reduction for homeowner and insurer alike. Its 120 mph warranted wind resistance provides verified performance in high-wind regions where wind uplift documentation is mandatory. The transferable Guardian Lifetime Limited Non-Prorated Material Warranty communicates its value in any real estate transaction or building inspection. For the tile roofing market, no competing product matches its combination of authentic profile, structural weight reduction, storm performance, and lifetime warranty coverage.

Who It's For
Mediterranean Metal Tile Roofing for Every Professional
Interlock Mediterranean Metal Tile Roofing brings the iconic barrel-profile aesthetic of Spanish and Italian clay tile to your home — at a fraction of the weight and without the fragility. Clay tile can exceed 900 lbs per square and requires substantial structural reinforcement. Interlock aluminum tile weighs just 70 lbs per square, making it structurally compatible with virtually any residential construction. Finished with the Alunar® 5-layer fluorocarbon coating, each hidden-fastener panel resists UV degradation, salt spray, moisture, and hail impact (UL 2218 Class 4). Wind resistance to 120 mph is warranted under the Guardian Lifetime Limited Non-Prorated Warranty. If you love the Mediterranean aesthetic but not the cost, weight, or fragility of clay, Interlock delivers the look you want — built to last a lifetime.

The Alunar® Coating System
Every Interlock Mediterranean Metal Tile panel is factory-finished with the proprietary Alunar® Coating System — a 5-stage molecular bonding process engineered to the most demanding performance standards for architectural coatings in North America. At its core, Alunar uses a 70% polyvinylidene fluoride (PVDF) fluoropolymer resin system — the same chemistry trusted by monumental and commercial building projects across the continent. Unlike painted steel or granule-coated asphalt products, PVDF fluoropolymer chemistry does not fade, chalk, peel, or blister. Color stability is independently verified to ASTM D-4214-07 (chalk resistance) and ASTM D-2244-16 (color retention) — requiring less than 5 Delta E units of color change after a decade of continuous UV exposure. Your roof's color is not applied to the surface — it is bonded into it. That is the difference between a finish that lasts 20 years and one that lasts a lifetime.
Layer 1 — Alunar® Coating System (PVDF Top Coat)
The outermost layer is Interlock's proprietary Alunar fluoropolymer finish — formulated with 70% polyvinylidene fluoride (PVDF) resin and independently verified to ASTM D-4214-07 for chalk resistance and ASTM D-2244-16 for color retention. This layer delivers color stability confirmed to less than 5 Delta E color change after ten years of continuous UV exposure. It is the permanent face of your roof.
Layer 2 — Primer Base Coat
A precision-applied primer layer bonds directly to the treated aluminum surface, creating the adhesion foundation that locks every subsequent layer in place. This primer is the structural bridge between the metal substrate and the PVDF color system — without it, no coating chemistry performs to specification.
Layer 3 — Conversion Coating
A chemical conversion treatment restructures the aluminum surface at the molecular level — transforming it from a passive metal into an active bonding substrate. This layer is critical to corrosion resistance and long-term coating adhesion, and is what separates an architectural-grade finish from a standard painted surface.
Layer 4 — Alkaline Cleansed
Before any coating is applied, each aluminum panel undergoes a multi-stage alkaline cleaning process that removes surface oxides, mill oils, and microscopic contaminants. This step is non-negotiable — surface cleanliness at this stage directly determines the lifespan of every layer above it.
Layer 5 — Aluminum Substrate
The structural foundation of every Interlock Mediterranean Metal Tile panel — 3003-H24 aluminum alloy, selected for its superior formability, corrosion resistance, and long-term dimensional stability. At 70 lbs per square, it delivers the mass profile of a premium tile product at a fraction of the weight of concrete or clay tile — requiring no structural reinforcement on standard roof framing.
Layer 6 — Back Coat
An applied protective coating on the underside of every panel guards against moisture infiltration, condensation, and galvanic corrosion from below. Most roofing products leave the back face uncoated. Interlock does not — because a lifetime warranty requires protection on all six sides of the panel.

Customer Reviews
What Homeowners Say About Interlock Metal Roofing
★★★★★This is the 3rd roof I have had put on by Interlock Roofing. I put one on my original house, my cottage, and now my new house. They have always done an excellent job, and the aluminum shingles are a great product — light, sturdy, and good-looking, even years down the road.
★★★★★We had our roof replaced in 2017 with an aluminum roof by Interlock Metal Roofing. We live on the lake, and prior to the replacement, we were spending thousands of dollars every year as the shingles used to fly away in the wind. We have never had any problems in the last 9 years. We had a great experience with Interlock Metal Roofing. They were very professional and did a beautiful job, although it was difficult as our roof is quite high. Our roof is still beautiful, and we have never had a worry about it.
★★★★★I LOVE MY INTERLOCK ROOF! No more climbing up there to clean it off, no more gritty stuff falling into my garden after a few years. It looks fabulous and does what it's supposed to! And then there are the installers: knowledgeable, attentive to detail, and personable. Ivan is a gem! He attended to the addition of a small bit of flashing efficiently and cleaned the whole roof with a blower in short order. After almost ten years, it's STILL the only roof I would choose!
FAQ
Mediterranean Metal Tile Roofing — Frequently Asked Questions
Everything architects, homeowners, and contractors need to know about Interlock Mediterranean Metal Tile Roofing.
How long does mediterranean metal tile roofing last?
Interlock Mediterranean Metal Tile Roofing is backed by a Lifetime Transferable Warranty, designed to outlast the structure it covers. Unlike asphalt shingles that require replacement every 15-25 years, Interlock aluminum panels resist corrosion, impact, and freeze-thaw cycling without degrading.
How much does mediterranean metal tile roofing cost?
Interlock Mediterranean Metal Tile Roofing is premium-priced relative to asphalt and is cost-competitive with real clay or concrete tile when full installation, structural reinforcement, and lifetime replacement costs are considered. Clay tile installations frequently require structural upgrades to support 850–1,200 lbs per square. At 70 lbs per square, Interlock eliminates that added cost entirely. Contact an authorized Interlock installer for a project-specific quote. Over 50 years, Interlock delivers superior financial return through eliminated replacements, zero maintenance costs, and avoided structural reinforcement expenses.
Is mediterranean metal tile roofing energy efficient?
Yes. Interlock aluminum panels reflect solar radiation and release absorbed heat rapidly after sunset, reducing attic temperatures and HVAC cooling loads compared to dark asphalt shingles. Most homeowners report measurable reductions in summer cooling costs.
What maintenance does mediterranean metal tile roofing require?
Virtually none. No painting, sealing, re-granulating, or re-nailing is ever required. Occasional rinsing to remove debris from valleys is all that is typically needed. Interlock eliminates roof maintenance from your annual budget.
How heavy is mediterranean metal tile roofing?
Interlock Mediterranean Metal Tile panels weigh approximately 70 lbs per square (100 sq ft). This is a fraction of the weight of concrete or clay tile (900+ lbs/sq) and natural slate (800-1,500 lbs/sq), making Interlock suitable for virtually any standard residential roof structure without structural reinforcement.
Can Interlock roofing be installed over my existing roof?
In many cases, yes — Interlock aluminum roofing can be installed over existing asphalt shingles without full tear-off, depending on local building codes, deck condition, and current roof layer count. Your authorized Interlock installer will conduct a decking inspection to confirm eligibility. Installing over existing roofing eliminates tear-off labor and disposal costs, reducing overall project expense. Where tear-off is required — due to soft decking, rot, or code restrictions on roof layers — Interlock installers manage the full removal process. Either way, the result is a permanent roofing system that will never need to be removed or replaced.
Does Interlock roofing qualify for home insurance discounts?
Yes — in many regions, Interlock aluminum roofing's UL 2218 Class 4 hail impact rating and 120 mph warranted wind resistance qualify homeowners for significant insurance premium reductions. Discount amounts vary by insurance carrier and jurisdiction, but Class 4 impact-rated roofing consistently triggers meaningful savings in hail-prone markets across North America. Contact your insurance provider to confirm available discounts before installation. Many homeowners find that insurance savings offset a meaningful portion of the installation cost premium within the first 10–15 years of ownership.
What colors is Interlock Mediterranean Metal Tile available in?
Interlock Mediterranean Metal Tile Roofing is available in nine standard colors: Solid Copper, Copper Penny, Hunter Green, Black, Deep Charcoal, Musket Grey, Tile Red, Colonial Brown, and Tudor Brown. All colors are finished with the Alunar® 5-layer fluorocarbon coating system, providing PVDF-grade color stability backed by a 30-year coating warranty per ASTM D-4214-07 and ASTM D-2244-16. Colors complement a full range of architectural styles and exterior palettes. Contact your authorized Interlock installer or visit the Interlock color selector to view samples in your regional lighting conditions before finalizing your selection.
Is Interlock Mediterranean Metal Tile fire rated?
Yes. Interlock Mediterranean Metal Tile panels are available in a Class A fire-rated assembly — the highest rating achievable under UL and ICC standards. Class A requires installation with GAF Versashield fire-resistant underlayment per ICC-ES Evaluation Report ESR-2053, in combination with the Interlock panel system per ESR-1790. Note: installation with self-adhered underlayment results in a non-classified fire assembly. Specify GAF Versashield when Class A fire rating is required by code or insurance. Confirm your underlayment specification with your authorized installer before project commencement.
Can the Interlock warranty be transferred to a new owner?
Yes. The Guardian Lifetime Limited Non-Prorated Material Warranty is transferable once to a subsequent owner. Original individual owners hold a lifetime warranty; organizations and subsequent individual owners hold a 50-year non-prorated warranty. A transfer fee of $300 applies, and transfer must be registered with Interlock Roofing within the required notification period. A documented Interlock roofing system with an active warranty adds measurable, verifiable value in real estate transactions. Contact Interlock Roofing directly to initiate the transfer process.
