An industrial building in Port Moody will likely need a new roof after an early morning blaze that kept fire crews busy for several hours on Thursday. The fire was called in just after 4 a.m. By the time crews arrived, it had already spread to the roof, causing it to partially collapse.

Adding to the difficulty, the building was well secured and the power and machinery inside were still running.

"It was difficult in the fact there was a fire burning under collapsed roofing materials, and [crews were] working around a structure that's not stable," said Port Moody deputy fire chief Gord Parker.

The building is home to a metal products company.

Firefighters were kept outside the building until the power could be shut off.

Despite the size of the blaze, Parker said the building was saved, along with some of the equipment inside.

"Fortunately, we were able to keep it contained," he said.

By 8 a.m., crews were in the cleanup stage.

The fire shut down Murray Street, causing heavy delays during the morning commute. Investigators were expected to be at the scene all day, however Parker said there is no indication of arson.
