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 steel is produced according to European building standards, which are significantly stricter than North American requirements. That means higher performance, better protection, and greater long-term reliability.
Here’s what sets this steel apart:
A zinc-magnesium coating, which offers stronger corrosion resistance than basic zinc
A G90 rating - the highest level of galvanization available for residential roofing
A 25-gauge thickness (around 0.5 mm), far superior to the 29-gauge metal commonly used by other manufacturers
It’s thicker. It’s tougher. And it’s built to last.
And the Paint? It’s a Whole Other Level
Once the steel is formed, it goes through a hot-dip galvanization process, where it’s fully coated in a protective layer of zinc-magnesium.
Here’s where things get technical - and why it matters:
A 10-micron primer is applied to both sides of the steel (compared to 7 microns or single-side application by many competitors), ensuring better adhesion and long-term protection.
A 10-micron epoxy layer is added to the underside for moisture resistance.
The top side is finished with 35 microns of baked-on German paint for Monterey Wrinkle Matte, and 36 microns for Monterey Icecrystal - both rated RUV 4, the highest UV resistance level in the metal roofing industry.
For comparison, many other metal panels use only 23 microns of paint on the visible side.
That’s where fading starts - and where our material continues to shine year after year.
Monterey Icecrystal - Durable and Distinctive
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 this checklist handy. Because when you're investing in a roof that should last 40 to 50 years, trust - but verify.
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.
