Flat Roof Ventilation with the Construction

This is a quick way to make a huge hole.  As you can see they cut right through the horizontal rafters the main supports run in line with the way they are cutting.  This information is obtained by taking the time to complete an inspection hole 45degree angle to the outside load bearing wall.  Armed with the right information we can maximize our time on the roof and get some ventilation for the engine crews.
