What is Stone-Coated Metal Roofing?

It used to be that there were only a couple of types of metal roofing — corrugated metal, which has certainly improved over time but aesthetically has always been limited in options, or the much more costly copper cladding, such as that seen on the dome of the Arizona Capitol building.

Today, there are many more options, including the latest product – stone-coated metal roofing. Stone-coated steel roofing is combined with the look of tile, shake or shingle to give a strong, durable roof along with fantastic good looks. Whatever the style of your home or property, you will likely be able to find a metal roofing product to match your needs.

Perhaps the most amazing thing, besides the beauty of the products is its longevity. An asphalt or composite roof will need to be replaced every 10 to 20 years, while stone-coated steel is virtually good for a lifetime. In fact, Gerard Stone Coated Steel Roofs come with a lifetime warranty and that warranty is transferable to the next generation. This makes metal roof options particularly attractive for a commercial property. It may be more expensive than traditional roofing options, but it generally last forever with minimal maintenance.

Many of the products offer incredible protection:

  • Graniteshield’s Stone-Coated Steel Roofing is warrantied for up to 2.5 inch diameter hail (that’s baseball size!).
  • Steel roofing can withstand winds up to 170 mph, making it fantastic for hurricane prone areas.
  • The interlocking panels make it exceptionally strong, which is extremely useful in earthquake zones.
  • The roof panels won’t split, curl, crack, warp or absorb water making it great for areas with extreme climates.
  • The stone coating is UV reflective, sending heat back into the atmosphere and not into your home or commercial property.
  • In general, the product is 50% lighter than more traditional asphalt or built-up roofing, which means there is no need for additional structural reinforcement.
  • Since everyone is concerned about the environment these days, the good news is that when the roof does wear out, the steel panels are 100% recycleable.
  • Little or no maintenance is needed — generally, just hosing the roof clear of debris is enough.

There are a dozen or so manufacturers out there that offer a wide array of products — Union Corrugating Company, Allmet Roofing Products, Graniteshield, Gerard, Decra, Metro Roof Products and more.

Keep in mind that stone-coated metal roofing is significantly more expensive than more traditional products, until you consider the cost over time. Since it doesn’t need replacing and requires very little maintenance, the roofing will pay for itself over time and then some.

Is A Stone-Coated Metal Roof Right for Me?

Is a Stone-Coated Metal Roof Right for Me?

When it comes to choosing a roofing material, the options can be overwhelming. From traditional asphalt shingles to modern metal roofs, each type has its own set of benefits and drawbacks. Among the various choices, stone-coated metal roofs have been gaining popularity. But are they the right fit for your home? Let’s explore the pros and cons to help you make an informed decision.

What is a Stone-Coated Metal Roof?

A stone-coated metal roof combines the durability of metal with the aesthetic appeal of natural stone. It typically features a metal base, such as steel or aluminum, coated with a layer of crushed stone granules. This design provides a unique blend of strength, beauty, and performance.

Benefits of Stone-Coated Metal Roofs

  1. Durability and Longevity
    • Resistance to Elements: Stone-coated metal roofs are known for their resilience against harsh weather, especially in hail prone areas such as DFW/Austin. These metal roofs can withstand heavy rain, high winds, and even hail, making them a reliable choice for various climates.
    • Long Lifespan: These roofs can last 50 years or more with proper maintenance, which is significantly longer than traditional roofing materials.
  2. Energy Efficiency
    • Reflective Properties: The stone coating reflects sunlight, which can help reduce heat absorption and lower cooling costs. This makes stone-coated metal roofs a good option for energy-efficient homes.
  3. Low Maintenance
    • Minimal Upkeep: Unlike asphalt shingles that may require regular inspections and replacements, stone-coated metal roofs generally need less maintenance. They resist moss, algae, and rot, reducing the need for frequent cleaning.
  4. Aesthetic Appeal
    • Variety of Styles: Stone-coated metal roofs come in a range of styles and colors that mimic traditional roofing materials like slate, tile, or wood shakes. This allows you to achieve the look you want without compromising on durability.
  5. Fire Resistance
    • Enhanced Safety: The metal base of these roofs is highly fire-resistant, providing an extra layer of protection for your home in case of a fire.

Drawbacks of Stone-Coated Metal Roofs

  1. Cost
    • Higher Initial Investment: Stone-coated metal roofs generally have a higher upfront cost compared to asphalt shingles or basic metal roofs. However, the long-term savings on maintenance and energy bills can offset this initial expense.
  2. Installation Complexity
    • Professional Installation Required: Proper installation is crucial for maximizing the benefits of a stone-coated metal roof. It’s best to hire a qualified contractor like PEAK Roofing & Construction, with experience in installing this type of roofing to ensure a job well done.
  3. Noise
    • Potential for Sound Issues: While the stone coating helps reduce noise compared to traditional metal roofs, some homeowners might still notice a difference in sound levels, especially during heavy rain or hail.
  4. Limited Availability
    • Regional Variations: Depending on your location, finding a contractor who specializes in stone-coated metal roofs might be more challenging. This can affect both the cost and the ease of installation.

Is a Stone-Coated Metal Roof Right for You?

Deciding whether a stone-coated metal roof is the right choice for your home involves considering various factors:

  • Budget: Evaluate if the long-term benefits justify the higher initial cost.
  • Climate: Consider if your local weather conditions, within the DFW/Austin areas, would benefit from the durability and energy efficiency of this roofing material.
  • Aesthetic Preferences: Think about whether the look of a stone-coated metal roof aligns with your home’s style.
  • Maintenance Preferences: If you prefer a low-maintenance option, this roofing type could be a good fit.

In conclusion, stone-coated metal roofs offer a blend of durability, energy efficiency, and aesthetic appeal that can make them an excellent choice for many homeowners.
