Is a 6-in-12 roof safe to walk?
The calculator only gives the geometry. The slope, the surface, and the site fall plan decide if anyone walks it.
Roofing questions before anyone steps on the deck
Pitch in inches per foot and in degrees, plus the rafter line in inches and millimeters. Falls are decided by the site plan, not by how dry the shingles look.
- Measure rise and run the way the calculator asks, then scale the rafter for the full run.
- Confirm the deck is sound for the system you are installing.
- Flash walls and penetrations the way the manufacturer shows.
- Set fall protection before the work, not after the first slip.
Common questions
Does the pitch include the overhang?
No. Overhang, ridge, and the seat cut are extra.
