Roofed

The roofer roofed the thick roof.

Now and then we passed a moorland cottage, walled and roofed with stone.

Have you heard of the great Forest of Burzee? Nurse used to sing of it when I was a child. She sang of the big tree-trunks, standing close together, with their roots intertwining below the earth and their branches intertwining above it; of their rough coating of bark and queer, gnarled limbs; of the bushy foliage that roofed the entire forest, save where the sunbeams found a path through which to touch the ground in little spots and to cast weird and curious shadows over the mosses, the lichens and the drifts of dried leaves.

Amphitheatres are not usually roofed.
