I am having a bit of trouble accessing the attic in my new home. I live in a rowhouse with a flat roof, the attic is as such not very tall and there are some beams that prevent me from moving freely around the attic. My question is simple, I am sure it is a bit unorthodox, but would it be possible enter the attic through the air return vent? It is rather larger, definitely two joists and is well situated to enter the area of the attic I need. Can I simply unscrew it and push it in or am I likely to do too much damage?
Any thoughts or suggestions?
