Colin Kelley & Mark Carcamo: “From the Rig to the Roof”

The importance of roof operations extends far beyond the physical act of vertical ventilation. Although arguably the most important reason for going “topside”, vertical ventilation is only one half of the total value of a company on the roof. Generating “lift” of the “neutral plane” and “leaning” out the fire in the interest of locating and facilitating a safer, faster knockdown is job number one of the roof team. However, the information an experienced roof company can provide for the overall stabilization of the incident can help the I.C. make an intelligent “guess” for a “go/ no go” decision. The value in the information relayed to the interior companies, as well as the incident commander, can truly lend itself to FF life safety and incident stabilization. The roof team, often times, has a global view of the structure and can provide critical information like construction type and overall span of said construction, specifically when dealing with lightweight versus conventional and any associated fire involvement and heavy loads being supported. They are often the first ones to obtain a C‐side view of the rear of the structure.
