Peg-tiles, also called plain, flat or pin tiles, are flat rectangular tiles of a red or orange colour. The tiles have small holes at one end into which oak pegs (hence the name) were inserted, these pegs were then hooked over riven oak lathes attached to the roofs. Later on the tiles were sometimes nailed in place using these holes. This type of tile was in use by the 13th century and continued in use into post-medieval times.
