The Problem with Ribbed Steel Roofing: Snow Slides Off—And So Does the Paint!
Here’s what a typical ribbed steel roof can look like after just 15 – 20 years—faded, peeling, and worn.
If you’re looking for a roofing solution that maintains its beauty and performance for decades, stone-coated metal roofing is the smarter, longer-lasting choice.

Why Stone-Coated Metal Roofs Outperform Ribbed Steel in Ontario’s Climate

When it comes to long-term value and appearance, stone-coated metal roofing consistently outperforms traditional ribbed steel roofing. If you’re investing in a roof for your Ontario home, understanding the differences in durability, maintenance, and aesthetics is key.

Stone-Coated Roofs Maintain Their Beauty for Decades

Unlike ribbed steel roofs, which often begin to peel and fade within 10 to 15 years, stone-coated metal roofs retain their original look for much longer. The stone granules are bonded to the steel panel, helping resist the harsh effects of UV exposure, extreme weather, and snow accumulation.

Repainting a Ribbed Steel Roof? Here’s the Catch

Once the factory paint on a ribbed steel roof starts to degrade, repainting cannot match the quality of the original factory finish. Factory-applied coatings are cured under controlled temperatures and conditions—not something that can be replicated on-site.

Issues with repainting include:

• Moisture in the air during application

• Inconsistent drying times

• Lower durability of air-dried paints

• Increased risk of peeling, fading, or visible lap marks (like tiger striping)

In fact, repainting a metal roof may void its warranty, and mismatched colors can make the roof look uneven and aged.

Replacement vs. Repainting: The Costly Reality

If a significant portion of your ribbed steel roof fades or peels, you may find yourself replacing multiple panels to restore a uniform appearance. This can be expensive and time-consuming, especially since repainted areas often discolor differently over time compared to the original panels.

Curb Appeal & Protection Matter

Your roof is one of the most noticeable features of your home. It not only contributes to curb appeal but also protects your home from the elements. Choosing a roof that’s prone to fading, peeling, or discoloration simply doesn’t make sense in Ontario’s harsh and variable climate.

The Smarter Choice: Stone-Coated Metal Roofing

In our experience, stone-coated metal panels offer superior performance, enhanced curb appeal, and a longer lifespan compared to ribbed steel. They’re also backed by a 50-year transferable warranty, making them a smart investment that adds real value and peace of mind—especially when it comes time to sell.
