What does Skim Cut accomplish?

Explanation:
Skim Cut is about quickly exposing the space beneath the roof while preserving the structural members. The cut is made through the roof covering and the roof decking, but stops short of cutting into the underlying structural members like rafters or trusses. This creates a vent opening that lets heat and smoke escape and gives a view of what lies inside so crews can decide on the next steps. The key idea is to open the deck and covering only, not the roof members, which is why that description fits best. It’s not about starting with member detection, and it doesn’t involve cutting through the roof members themselves.
