SCROLL TO EXPLORE
Roof & Building Service Intl. (RBS) delivers integrated roofing, building envelope, and specialized contracting for the people who own, manage, and operate complex facilities — from existing assets to new developments.
Our Story
From a Roofing Company to a Strategic Building Partner
40+
Years of Experience
RBS traces its roots to 1984, when founder Brian A. Ricardo established Ricardo Roofing Ltd. in the Greater Toronto Area. In 1993 the company relocated its head office to Eastern Ontario to serve a growing client base, earning a reputation for solving complex roofing challenges through quality workmanship, responsive service, and reliable delivery.
As our clients' needs grew, so did we. In 2013 we rebranded as Roof & Building Service Intl. (RBS), broadening our scope to serve both roof and full building requirements under one banner.
Today, with more than 20,000 projects completed across Ontario, RBS is a trusted partner to industrial, commercial, institutional, and government clients — from food-processing plants and healthcare facilities to logistics hubs and municipal buildings.
We're more than a contractor. We're an advisor, problem-solver, and long-term partner.
