Metal Shingles
Individual metal panels stamped or formed to resemble traditional shingle, slate, or shake profiles, offering the durability and longevity of metal roofing in a familiar shingle format.
Specifications
| Materials | Steel (galvalume or galvanized), aluminum, copper, zinc |
| Weight | 50 to 150 lbs per square (significantly lighter than asphalt) |
| Typical Lifespan | 40 to 70 years depending on material and coating |
| Wind Rating | Up to 120 mph or higher depending on product and fastening system |
| Fire Rating | Class A (non-combustible) |
Common issues
- Denting from large hail, especially on thinner-gauge steel or aluminum products
- Coating or paint system degradation over time requiring touch-up or recoating
- Expansion and contraction noise in extreme temperature swings if not properly fastened
- Higher upfront cost creating sticker shock compared to asphalt alternatives
Insurance relevance
Metal shingles have a Class A fire rating and high wind resistance, which can qualify for insurance premium discounts in many states. Hail damage on metal shingles presents as dents rather than granule loss or mat fractures, making damage assessment different from asphalt. Cosmetic damage exclusions in some policies may deny claims for dented metal shingles that are still functionally intact. Replacement costs are significantly higher than asphalt, so when a covered loss occurs, the claim value is larger.
What Are Metal Shingles
Metal shingles are individual roofing panels made from steel, aluminum, copper, or zinc, stamped or formed into profiles that replicate the appearance of traditional asphalt shingles, wood shakes, or natural slate. Unlike standing-seam metal roofing, which uses long vertical panels with raised seams, metal shingles are installed in individual pieces or small panels that interlock with each other. This gives them a familiar residential appearance while delivering the longevity and fire resistance of metal. Metal shingles are significantly lighter than asphalt (50 to 150 pounds per square versus 200 to 350 for asphalt), which reduces structural load. They carry a Class A fire rating and wind ratings that typically reach 120 mph or higher depending on the interlocking system.
Metal Shingle Materials and Coatings
The most common metal shingle material is steel with a galvalume coating (an aluminum-zinc alloy) and a factory-applied paint system, often Kynar 500 or Hylar 5000 (PVDF-based coatings) that resist fading and chalking for decades. Aluminum shingles are lighter and naturally corrosion-resistant, making them a strong choice for coastal environments where salt air corrodes steel. Copper shingles are the premium option, developing a distinctive green patina over time and lasting 70 years or more. Zinc shingles also develop a natural patina and are common in European installations. Stone-coated steel shingles add a layer of ceramic-coated granules over the metal surface, giving them an appearance very similar to asphalt architectural shingles while retaining metal durability.
Installation Considerations
Metal shingles install over standard plywood or OSB roof decks with synthetic underlayment. Most systems use concealed fasteners or interlocking clips rather than exposed nails, which eliminates fastener penetrations on the weather-facing surface. Each shingle interlocks with the adjacent pieces on all sides, creating a continuous weather barrier. Because metal expands and contracts with temperature changes, the fastening system must allow for this movement. Over-driven screws or clips that do not permit movement can cause buckling or noise during temperature swings. A high-temperature ice and water shield underlayment is recommended in cold climates because standard self-adhering membranes can degrade under the heat that metal roofing transfers on hot days.
Metal Shingles and Insurance
Metal shingles offer several insurance advantages. The Class A fire rating can reduce premiums in wildfire-prone areas. The high wind rating qualifies for wind mitigation credits in many coastal states. However, hail damage on metal shingles is assessed differently than on asphalt. Hail dents metal without breaking it, so the roof may still be functional even if cosmetically damaged. Some insurance policies include cosmetic damage exclusions that deny claims for functional metal roofing that has been dented but not punctured. Homeowners considering metal shingles in hail-prone regions should review their policy for this exclusion before investing. When a covered loss does require replacement, the higher material cost of metal shingles means the claim value is significantly larger than an equivalent asphalt roof, so accurate documentation of the shingle type and material is important for proper Xactimate pricing.
Frequently asked questions
Metal shingles typically last 40 to 70 years depending on the base metal and coating system. Steel shingles with a galvalume (aluminum-zinc alloy) coating and a high-quality paint system can reach 50 to 60 years. Aluminum shingles resist corrosion better in coastal environments and last 40 to 50 years. Copper and zinc shingles can exceed 70 years but are significantly more expensive.
When properly installed over a solid roof deck with underlayment, metal shingles are not significantly louder than asphalt shingles during rain. The noise concern comes from standing-seam metal roof panels installed over open framing with no solid decking beneath, which acts as a drum. Metal shingles installed on standard residential roof decks with plywood or OSB sheathing and synthetic underlayment have sound levels comparable to other roofing materials.
Yes, metal shingles can dent from hail, particularly from hailstones 1 inch and larger. The severity depends on the metal type, gauge thickness, and profile design. Textured or ribbed profiles hide minor dents better than smooth surfaces. Some insurance policies include cosmetic damage exclusions for metal roofing that deny claims for dents that do not affect the roof's function. Check policy language before selecting metal shingles in hail-prone areas.
