Ross Roof Group is a New Zealand business that has been involved in the roofing industry for over 75 years. Originally making concrete blocks and concrete tiles back in 1942, the business soon grew and became known as Ross Concrete Products, and later Ross Roofing. Over the years, the company has been evolved and transformed into Ross Roof Group, which manufactures both pressed metal brands Metrotile and Tilcor.

Our Vision:

To provide home owners around the world with a quality roofing product, by using the very best New Zealand raw materials in our production and then doing business with them as if they are family.

Our Values:

We are keeping our eyes open and our minds active, hungry to make things better, easier, safer, smarter.

Quality is everything for us from what we produce, how we behave, the way we do business. Quality and integrity is our north star.

We’re working alongside each other and our partners with respect, good feeling and real productivity; we get to great solutions together.

We're supporting each other, making our actions count and focusing on the things that matter to fulfilling our purpose.
