How to make attic easier to traverse?
I live in Florida too so I know exactly what you mean about hot attics. I had the same problem except for the pvc water pipes. I put up a number of 2 by 8 feet of 3/4 inch plywood on the rafters. Where it was possible to move over some of the cables, I did it. where I couldn't move them, I took some 2x4's, notched them for the wires to go thru and put them over the rafters and then plywood on top, like a false floor. You do not want to notch your rafter. No matter what you do, your time will be limited just because of the heat. You have to make sure you don't get dehydrated. The last thing you want to happen is be back there working and start to get dizzy and then take 30 minutes to get out....been there, done that, not fun.
