Understanding Stone Coated Steel Roofing vs. Galvanized Steel Roofing for a Durable Roof
City skyline
When it comes to picking the right roof for your home or business, it's easy to get lost in the sea of materials. Asphalt, wood, tile, metal — oh my! But if you’ve narrowed it down to steel roofing sheets, you’re already on the right path to durability. Now comes the showdown: stone coated steel roofing vs. galvanized steel roofing.

Think of it like choosing between two superheroes — both strong, both reliable, but with very different styles. In this blog post, we’ll break down these two roofing types, compare their pros and cons, and help you decide which one is best suited for your property in Grant, MI, and surrounding areas. Let’s dive into the steel showdown.
What Is Stone Coated Steel Roofing?
Stone coated steel roofing is like the stylish cousin of traditional metal roofs. It combines the toughness of steel with the charm of traditional shingles or tiles.
What Makes It Special?
- Durable Steel Core: At the heart of each panel is corrosion-resistant steel that stands up to harsh weather like a champ.
- Stone Coating: A layer of stone chips is bonded to the steel, giving the roof texture, color, and visual appeal.
- Protective Barrier: An acrylic glaze over the stone layer provides UV protection and extends the lifespan.
Why Homeowners Love It
- Curb Appeal: If metal roofs seem a bit industrial to you, stone coated versions offer a more traditional look that blends beautifully with any home design.
- Longevity: These roofs can last 40 to 70 years — nearly a lifetime.
- Weather Resistance: They’re highly resistant to wind, hail, heavy rain, and even fire.
- Low Maintenance: The protective coating reduces the risk of rust or corrosion.
Potential Downsides
- Price: They’re more expensive than galvanized steel roofing upfront.
- Installation: It requires professional installation due to its unique interlocking system and heavier weight compared to standard steel sheets.
In short, stone coated steel roofing is the "beauty and the beast" of the roofing world — strong as steel, but good-looking enough for a home magazine spread.
What Is Galvanized Steel Roofing?
If stone coated steel is the flashy cousin, galvanized steel roofing is the tough, no-nonsense sibling. It's all about performance and practicality.
The Basics
Galvanized steel is made by dipping regular steel into molten zinc. This zinc coating acts like armor, protecting the steel from rust and corrosion.
Benefits of Galvanized Steel Roofing
- Affordability: Galvanized steel roofing is more budget-friendly than its stone coated counterpart.
- Durability: While it might not be as long-lasting as stone coated steel, it still offers 30 to 50 years of solid performance.
- Lightweight: It’s easier to transport and install, which could mean lower labor costs.
- Eco-Friendly: Steel is recyclable, and many galvanized roofs use recycled materials.
Where It Falls Short
- Appearance: It has a shiny, metallic finish that may not suit all styles of homes.
- Noise Factor: Rain sounds louder on a galvanized steel roof — charming for some, irritating for others.
- Rust Over Time: The zinc layer protects the steel, but once it wears off (especially around cut edges), rust can sneak in.
For homeowners who want a cost-effective roof that gets the job done with minimal fuss, galvanized steel roofing is a solid pick — literally.
Comparing Stone Coated and Galvanized Steel Roofing: The Face-Off
Let’s stack these two side-by-side in a few key categories to help you make a confident decision.

1. Aesthetic Appeal
- Stone Coated: Mimics shingles, clay, or tile; offers multiple colors and textures.
- Galvanized: Industrial, metallic look; limited design options.
2. Lifespan
- Stone Coated: 40 to 70 years.
- Galvanized: 30 to 50 years.
3. Cost
- Stone Coated: Higher upfront cost.
- Galvanized: More affordable.
4. Maintenance
- Stone Coated: Virtually maintenance-free.
- Galvanized: May need inspections for rust and wear over time.
5. Installation
- Stone Coated: Heavier; requires professional installation.
- Galvanized: Lightweight; easier and faster to install.
6. Weather Resistance
- Both types hold up well in Michigan’s snowy winters and stormy springs, but stone coated edges out slightly in hail and wind resistance.
At the end of the day, your choice may come down to budget, style preference, and how long you plan to stay in your home.

FAQs
Is stone coated steel roofing louder than shingles in the rain?
Nope! Thanks to its stone coating and solid underlayment, it’s actually quieter than traditional metal roofs — sometimes even quieter than asphalt shingles.
Can galvanized steel roofing rust?
Eventually, yes. While the zinc coating provides great rust resistance, over time (especially at edges and cuts), it can wear off and allow rust to form.
Is one steel roofing option more energy efficient than the other?
Stone coated steel roofing tends to perform better with insulation and heat reflection due to its multi-layer structure, making it more energy efficient overall.
Can both roofing types withstand snow and ice?
Absolutely. Both are well-suited for snowy climates, but stone coated steel may offer better traction for sliding snow and ice, reducing buildup.
Which roofing type is better for resale value?
Stone coated steel roofs often boost a home's resale value more, thanks to their long life, great looks, and energy efficiency.
