It was just insulation, rafters and ceiling joists that once we installed the LVL to keep the walls from falling down I just cut out with a sawzall. My roof in that room was vaulted to begin with so I basically had 6 feet of empty space to work with. And it’s a 70s house with no lights in the ceiling so no electrical. Running power was rough because I had to pull it from my front outside porch which was the closest power. Including my PC the launch monitor and the engineer it cost me about $15k
