Peaked roofs have some different considerations than flat roofs. First and foremost is gaining access to the roof. Ideally ,you will be able to position the apparatus so the aerial ladder will allow the easiest way to the roof. Pulling past or stopping short of the building will sometimes provide the best access. Conduct a size-up as you pull onto the street, location of the fire, presence of wires, and any other obstacle to positioning the apparatus. Remember, you're positioning the turntable and not the cab. Many times members have used the cab to position the apparatus and found out it was in a less than ideal position. Slow down and use your head.
Once you have positioned the apparatus and are raising the aerial, take a look at the fire or smoke and see which direction the wind (if present) is blowing. This will give you a clue to the best spot to start venting. Bring the right tools with you. We don't use power tools on peaked roofs so make sure you have an axe or adz with you. I prefer a Flathead axe myself, but whichever one you're comfortable with use it.
After gaining access to the roof and when you have found the ideal spot to vent, begin to vent. If possible, open up on the leeward side of the roof as close as possible to the seat of the fire. Try to open up as many bays as you can. Depending on the slope of the roof, you might be able to make the vent hole as big as 4' x 4' but don't count on it. Never over reach while swinging a tool. You want to have as much control as possible without jeopardizing your footing. I've seen videos where an axe was used to get a foothold and I'm sure it could work. But I wouldn't try it.
If you can only make it 2' wide then increase the length of the horizontal opening as long as you can. If the attic space is unfinished no other operations are needed. If the space is finished, use your tool or the rake on the aerial and push down on the material with the butt end. Using the butt end of the tool will ensure the tool will not get stuck while you're clearing the way.
When your done return to the ground for another assignment.
