Reciprocating saw for roof ventilation
VENTILATION TACTICS FOR PITCHED WOOD ROOFS
We recently got an 18V cordless Dewalt recip saw for extrication use. I read this article and thought it was a good idea.
Has anyone ever used a cordless recip saw for cutting a wood roof? How did it work for your department?
Hadn't thought about it before you brought it up
I guess I hadn't considered using a recip saw for roof ventilation. My biggest concern (as others have stated) would be the potential build-up of multiple layers of roofing material. Occasionally, we might run across a section of roof with 4-5 layers of asphalt shingles (not up to code, but when the homeowner does it himself, what are you going to do?).
Otherwise, it sounds like it could work well, and that's the key to ventilation - do whatever you can do well.
Personally, I hate using an axe for ventilation, like jerrygarcia does. Just my personal preference. The axe sometimes seems to 'bounce' when I get between the rafters, and doesn't cut as well. If I've sounded the roof carefully, I can cut a 4' x 4' vent with barely scratching the center supporting rafter. I like to use a common ventilation (chain-style) saw with the depth guide. We have a K-12, but it's a bit unwieldy for me (I'm not a very big guy).
One other thing that puzzles me...there was a quote from the article that someone posted:
'verticle roof ventilation isn't completed until the main body of fire is knocked down'
So, what do you do to ventilate as the attack team is making their initial attack? What if you have a backdraft situation set up, and the only safe way to eliminate that hazard is through vertical ventilation?
