- Roof having slope 7:12 (30.26°) is walkable but caution is required.
- On Roof having slope between 8:12 to 10:12 (33.69° to 39.81°), walking is not recommended. Extreme caution is required.
- Roof having slope greater than 11:12 (42.51°) is too steep to walk on.Roof jacks, Scaffolding, affixed ladders etc. needed for installation, insection and repair.
