Engineer Caleb Eiriksson from Fort Walton Beach (FL) Truck Co. 6 sent in some photos of how he and the Truck 6 crew recently spent an afternoon out in their first due. They wanted to come up with options of how they could utilize a roof ladder on a large steep pitched roof. Obviously, being able to get the truck into position would eliminate the need for these options, but they wanted to see what other options they could find.
The first thing they tried was using a 24’ extension ladder and conjunction with a 16’ roof ladder. Which is traditionally their go-to option when dealing with most residential roofs in their area. Due to the pitch and height of the roof, this option was not able to reach the peak. This roof was too steep to walk on, and there were no valleys present to aide in the assent to the peak.
The next option they tested was using the same 24′ extension and 16′ roof combo. This time they matched the angle of the roof pitch with the 24 footer and then made a transition to the 16’ roof ladder. As you can see from the photos, this option got them closer, but still came up short of the peak. This option would certainly work on a shorted height roof with this same pitch. It’s worth mentioning that the bed section of the ladder is facing out (up) and the fly section is lying flat on the roof. Using the ladder is this fashion eliminates the ladder bouncing as you ascend the ladder.
The next option they tested ended up being the winner for this particular roof: a 35’ extension and a 16’ roof ladder. By matching the angle of the roof, they essentially made the individual ladders into one long ladder. This combination proved to be a very stable working platform. Again, as mentioned earlier, the bed section of the ladder is facing in (resting on the roof) and the fly section is facing out to minimize the ladder bounce. They found the best way to get the ladder in place was to rest the beam on the roof, extend the ladder, then rotate into the bed down position on the roof. Once the 35′ is in position, simply ascend the 35′, and place the 16′ to the peak to get the job done.
While this might not be an everyday roof tactic, it got the crews out into their first due, and they worked trough a challenge together. They worked through the challenge in a non-emergency situation, and would now be better prepared to deploy it for real if the need arose.
A special thanks to Engineer Eiriksson and the Truck 6 crew (Captain Mosley, Firefighter Corrigan, Firefighter Dowd, and Firefighter Shalduha) for thinking out of the box and taking the time to share what they found.1 comment
