Why do I see firefighters cutting holes in the roof of a building on fire?

This is called "venting the roof" or "ventilation." It is impossible for firefighters to see in such an environment. When a hole is made in the roof because the building is "vented," the smoke and gases escape because heat and smoke rise. It makes it much easier for the firefighters in the building to see.
