Plain or faced corrugated paper-board &c. 10, 11 has holes punched in it, e.g. using a pointed tool and a female die, so that the material of the board is upset to form skirts 10a, 11a, and plastic or concrete studs 12 are inserted and allowed to set.

The boards may be impregnated or covered with asphalt before the roofing is laid.
