The Roka family has been deeply rooted in the building business since 1972.

Our primary service radius is 200 km’s from our head office. However we can have many products drop shipped just about anywhere in Canada.

Rudy Roka, the father of the family, started the outfit as a rough lumber saw mill. After the early demise of Rudy Roka, the rest of the family members, lead by John, the eldest son, have grown the business to present day status. Expect a level of service care unparalleled in the industry!
