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 thereās 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.

Hereās 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
Itās thicker. Itās tougher. And itās built to last.
And the Paint? Itās a Whole Other Level
Once the steel is formed, it goes through a hot-dip galvanization process, where itās fully coated in a protective layer of zinc-magnesium.
Hereās where things get technical - and why it matters:
A 10-micron primerĀ 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 layerĀ is added to the underside for moisture resistance.
The top side is finished withĀ 35 microns of baked-on German paintĀ for Monterey Wrinkle Matte, and 36 microns for Monterey Icecrystal - both rated RUV 4,Ā the highest UV resistance levelĀ in the metal roofing industry.
For comparison, many other metal panels use only 23 microns of paint on the visible side.
Thatās 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, youāll know exactly where your roof came from - and so will any future buyer.
Hereās the truth: theĀ only reliable wayĀ to verify the origin of roofing material is by checking for this print. If thereās no marking, thereās no way to confirm where it came from - no matter what a salesperson tells you.
So if youāre ever unsure, just turn the panel over.Ā No print?Ā That material could be from anywhere. And when youāre investing in something thatās supposed to last for decades, thatās a gamble you donāt want to take.
What to do next - you might ask? Itās simple
Ask justĀ one questionĀ 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 itās made of, or how it was produced. It could be from anywhere, and youāre taking a gamble.

If there is a print, then itās worth asking:
What gauge is the steel?
What grade of galvanization is used?
Whatās 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 youāre going to invest in a metal roof, make sure you know what youāre 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, youāve seen the pictures.
