How do you vent a roof fire?
Step-by-step: Open the roof; knock the decking or boards out of the hole; communicate with attack crews; push the ceiling down to vent the interior; tell command via radio that “the roof is opened”; and get off the roof. This part of their job is done, for now, and there’s plenty more left to do on the fireground.
What is the preferred method of ventilation for attic fires?
Utilize gable vents, or multiple attic vents while ventilating an attic fire. If vertical ventilation techniques are considered, open the roof near the peak over hot spots.
Why do they vent the roof in a fire?
When a hole is made in the roof, the smoke and gases escape. Venting the roof makes it easier for firefighters to see and find the source of the fire, and it also reduces the possibilities of backdraft and flashover.

Vertical ventilation takes place through holes cut in the roof, typically by truck companies during the early stages of a fire in a process known collectively as roof operations, while horizontal ventilation usually takes place through doors and windows.
When should you ventilate a fire?
Ventilation should be considered prior to fire crews operating inside a structure. Because not all fires (or buildings for that matter) are created equally, we should not necessarily hold back fire attack operations until a hole is cut; however, fire growth should be on everyone’s mind.
How do I Fireproof my attic vents?

How do you vertically ventilate?
Vertical ventilation is the removal of super-heated toxic gases and smoke by allowing it to take its natural traveling path – UP! Fire companies make this possible by accessing the roof with a ladder, saws and other tools, and making an opening on the roof’s exterior, then punching the ceiling out with another tool.
Are ridge vents fire safe?
Ridge vents are virtually invisible from the street and keep the roof deck clear for solar panels. Our ridge vents have a CC1/Class A Fire rating, making them the perfect solution for wildfire-prone areas.
