What is your roof made of?

A First, Take a Look at the Results

Some roofs start peeling, fading, or chalking just a few years after installation, even though they looked nearly identical when new. Others keep their color, texture, and strength for decades - even after facing harsh Canadian winters.

It All Starts With the Steel

At MROOF, we only use steel from ThyssenKrupp Steel Europe, a manufacturer with over 200 years of metallurgical experience, founded in 1811. That already puts them in a league of their own - but there’s more.

ThyssenKrupp makes and coats the steel in Germany. The finished coils are shipped to Ontario, where they are slit and formed into roofing profiles.

Here’s what sets this steel apart:

• A ZM130 zinc-magnesium coating that helps protect the steel from corrosion

• A Pladur paint finish that adds colour and an outer layer of protection

• 25-gauge steel in the specification described by MROOF

It’s thicker. It’s tougher. And it’s built to last.

And the Paint? It’s a Whole Other Level

The ZM130 metallic coating is applied to the steel before the Pladur paint finish. These are separate layers, each with a role in protecting the panel.

Here’s where things get technical - and why it matters:

• The primer helps the paint finish bond to the coated steel.
  

• The brochure specifies 10 micrometres of reverse-side protection.
  

• The brochure specifies a 35-micrometre top coat. Ask for the finish and coating thickness specified for the panels in your quote.
  
  
  
  

  
  

Compare finish specifications using the documentation for the exact panels quoted.

Colour retention depends on the selected finish and the conditions the roof is exposed to.

Monterey Icecrystal - Durable and Distinctive

The Icecrystal design is exclusive to ThyssenKrupp and the only one of its kind in the world. It features a unique texture combined with 36 microns of scratch-resistant paint, delivering both exceptional durability and visual attractiveness.

And Yes - You Can Trace It All Back

Every ThyssenKrupp coil which we use in our manufacture includes a print on the underside showing:

• Manufacturer name: ThyssenKrupp Steel Europe

• Country of origin: Germany

• Date of production

• Batch number

This marking is your built-in guarantee. Even 30 years from now, you’ll know exactly where your roof came from - and so will any future buyer.

Here’s the truth: the only reliable way to verify the origin of roofing material is by checking for this print. If there’s no marking, there’s no way to confirm where it came from - no matter what a salesperson tells you.

So if you’re ever unsure, just turn the panel over. No print? That material could be from anywhere. And when you’re investing in something that’s supposed to last for decades, that’s a gamble you don’t want to take.

What to do next - you might ask? It’s simple

Ask just one question before choosing a metal roofing contractor:

"What is printed on the back side of the metal panels?"

If the answer is nothing - stop right there. No print means no proof. You have no way of verifying where the metal came from, what it’s made of, or how it was produced. It could be from anywhere, and you’re taking a gamble.

If there is a print, then it’s worth asking:

• What gauge is the steel?

• What grade of galvanization is used?

• What’s the paint and primer thickness in microns?

• Is it hot-dip galvanized, or just electroplated?

• Is the backside protected and primed?

Keep the material specification with your written quote and project records. For a Standing Seam roof, ask MROOF to explain the panel material, finish and concealed fastening proposed for your home.

Bottom Line

If you’re going to invest in a metal roof, make sure you know what you’re really getting. As the saying goes - you get what you pay for. The right material will protect your home, save you money, and give you peace of mind for decades.

The wrong one? Well, you’ve seen the pictures.
