Our History

Tilcor has its roots grounded in the roofing industry since the mid 1900's.

We originally made concrete blocks and concrete tiles back in 1942, the business soon grew and became known as Ross Concrete Products, and later Ross Roofing.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 last 70 years, the company has been evolved and transformed into a new stage called Ross Roof Group, which manufactures the Tilcor brand for America, Europe, Africa, Middle East, Asia and Oceania
