Stone-Coated Steel Roofing: Pros, Cons, and How to Maximize the Lifespan

Have you been considering a new roof for your home? Maybe you're tired of the look of your current shingles or want something more durable. Stone-coated steel roofing could be an excellent option to consider. This innovative roofing material combines the strength of steel with the beauty of stone granules for a roof that can last 50 years or more. However, as with any roofing material, there are pros and cons to weigh before deciding if stone-coated steel is suitable for your home. 

In this article, we'll explore the advantages and potential downsides of stone-coated steel roofing so you can make an informed choice. We'll also provide tips for maximizing the lifespan of a stone-coated steel roof once installed. By the end, you'll know if this roofing solution should make it onto your shortlist and how to get the most bang for your buck if you do choose it. Let's dive in! 

Steel Roof Lifespan: How Long Do Stone-Coated Steel Roofs Last? 

Did you know a stone-coated steel roof can last up to 50 years if properly maintained? That's a long time, so do not worry about replacing your roof! 

To help ensure the longevity of your steel roof, here are some tips to follow:  

  • Choose a high-quality stone-coated steel roofing system. Look for a minimum thickness of .45 mm and a strong galvanized steel substrate with protective metallic coatings like zinc or aluminum. Thicker, more durable panels will outlast thinner options. 
  • Select a reputable installer. Proper installation is key to a long-lasting roof. Look for a certified roofer near you with experience installing stone-coated steel roofs. They will know how to fasten the panels to withstand high winds securely. 
  • Inspect and clean regularly. Conduct yearly inspections to check for any damage or debris on the roof—clear leaves and branches to prevent water pooling and rust formation. For stubborn stains, use a pressure washer on a low setting. 
  • Re-coat when needed. The stone chip coating protects the steel underneath. Re-coating the roof every 10-15 years will maintain protection and refresh the appearance. Use a stone chip product meant explicitly for steel roofs. 
  • Avoid walking on the roof. Only walk on the roof if necessary, and wear rubber-soled shoes to prevent scratches and dents. Never walk on or apply heavy loads to the edge of the roof. 
  • Touch-up paint chips. Inspect the roof for any scratches or chips in the paint that expose the metal underneath. Touch these up with matching sealant or paint to prevent rust. 
  • Consider a warranty. Look for a stone-coated steel roofing product with at least a 30-year warranty for the metal panels and a 20-year warranty for the stone chip coating. The warranty will cover you if any defects arise. 

Taking good care of your high-quality stone-coated steel roof through regular maintenance can ensure that it lasts for decades. The minimal maintenance needed will give you peace of mind, knowing that your roof is well-protected against extreme weather and will remain attractive for years. 

Pros of Stone-Coated Steel Roofing 

A stone-coated steel roof has a lot going for it. Here are some of the main pros:  

  • Durability. These roofs are built to last. The stone coating protects the steel from weathering and corrosion, while the steel itself is already naturally resistant to rot, fire, and insects. A stone-coated steel roof can easily last 50 years and more with proper maintenance. 
  • Low maintenance. Unlike asphalt shingles, which need to be replaced every 10-15 years, stone-coated steel roofs require almost no maintenance. You only need to inspect them periodically and clear away any debris. 
  • Energy efficiency. The reflective surface of the stone chips helps deflect sunlight and keep heat out of the attic, improving the home's energy efficiency. This can lower utility bills, especially in warmer climates. 
  • Aesthetic appeal. Stone-coated steel roofs have an attractive, natural look resembling wood shakes or clay tiles. They provide dimension and texture to a roof, and the color options allow you to complement your home's exterior design. 
  • Environmentally friendly. These roofs are made from recycled materials and are recyclable at the end of their long lifespan. 
  • Affordability. Although stone-coated steel roofs have a higher upfront cost than asphalt, they pay for themselves over time, thanks to their durability and energy efficiency. Many homeowners find they offer the best value in the long run. 

To ensure that your stone-coated steel roof lasts for many years, it's essential to have it regularly inspected by a professional roofer in your area. They will remove debris and repair scratches or dents in the coating. With proper care and maintenance, your roof will provide you with many decades of use. 

Cons of Stone-Coated Steel Roofing

While stone-coated steel roofing has many benefits, there are a few downsides to consider before installing it on your home: 


Stone-coated steel roofing tends to cost more upfront compared to asphalt shingles. The initial investment can be 2-3 times higher. However, its long lifespan means lower maintenance and replacement costs over time. If budget is a concern, look for ways to offset the cost, like tax incentives, rebates, and financing options. 

Difficult Installation 

Stone-coated steel roofing can be more difficult to install than asphalt shingles, requiring specialized tools and skills. The stone coating and metal panels also make the roof heavier, requiring a stronger structure and support. Installation is best left to professional roofing contractors to ensure it's appropriately done according to the manufacturer's specifications. 

How much do stone-coated steel roofs cost? 

Stone-coated steel roofs are more affordable than natural stone or tile. Prices range from $10 to $25 per square foot installed. Several factors affect the cost:  

  1. Roof size and pitch. More complex roofs cost more to install. 
  2. Roofing material. Steel panels with stone chip coating cost less than those with natural stone. 
  3. Coating type. Larger stone chips and richer, more variegated colors tend to cost slightly more. 
  4. Installation. The overall cost includes the removal of the existing roof, flashing, vents, and any necessary structural upgrades. 

A stone-coated steel roof provides good value for the money. While the upfront cost may be higher than asphalt shingles, lower maintenance needs, and energy savings over its lifetime can make it a worthwhile investment.
