Ottawa Fire Services’ Stations No.36 and No.55, Ottawa, Ontario, Canada

Sloped and flat roofs are incorporated into the designs of Ottawa Fire Services’ Stations No. 36 and No. 55. Approximately 16,000 square feet of metal roof and wall panels were used on the two buildings. On both stations, the sloped portion of the roof is over an apparatus bay where fire vehicles are parked. Standing seam metal panels wrap around the building from the roof to walls.

Hobin Architecture Inc. and Morley Hoppner Ltd. completed the project as a design-build team. To create a watertight assembly, the wall panels were installed first, extending about 10 inches above the roof. Then, the panels were folded down onto the roof, and the edges were sealed with butyl sealant.

The roof panels were then installed on top, using closed rivets across the front seam where the roof panels meet the wall panels, creating the illusion from the ground that it’s one seamless panel encompassing the entire section of the building. Additionally, a knee plate was used within the seams to help create the seamless look and watertight performance at the transition. The fixed point of the panel was moved to the eave location to allow the panels to expand and contract at the ridge.

To complete the project, 16,000 square feet of The Garland Co. Inc.’s R-Mer Span 22-gauge preweathered Galvalume steel panels were installed. Also, S-5!’s ColorGard snow retention systems were attached to the roofs.

Ottawa Fire Services operates 45 stations to serve more than one million residents across more than 1,700 miles. Station No. 36 is in a developing industrial area and Station No. 55 is in a suburban area of the city among new housing developments.
