The History of Mainline Roofing

Mainline Roofing, one of the oldest members of the Roofing Contractors Association of BC (RCABC; members since 1968), was founded 50 years ago by Don Lyons. His architecturally trained partner, Richard Kosolofski, joined Mainline in 1979. A second generation roofing company, Mainline is now co-owned by Chris Lyons and Matt Kosolofski. They look forward to welcoming a third generation of roofers at Mainline.

Matt and Chris started their roofing careers as teens or younger. They now manage 20 staff members, including 18 roofers in the field.

Certified in fall protection and mobile equipment safety, Bob Fickell, Mainline’s Safety and Training Coordinator, has 20 years' experience in the roofing Industry.

Mainline covers “every corner of BC” and values workers with a positive, can-do attitude.
