Protection from the world or from "the elements"
- A last step or finishing touch, as a roof is the last part finished when a house is built
- Something that seems over your head or unattainable
- A lid or a cap—a limitation on how high you can go or how much progress you can make
- The greatest, highest, or utmost
- A higher or insightful perspective, as you would have if you were on a roof looking down
