The building industry divides roof coverings into two broad categories: 1) built-up roof coverings and 2) prepared roof cover- ings. Built-up roof coverings consist of several layers of materials applied to a roof. For example, a tar and gravel roof covering is a built-up roof. This roof covering is used on flat roofs. Prepared roof coverings are used on peaked roofs, and these materials are usually nailed to a wood roof deck. The most common prepared roof coverings are slate, tile, wood shingle and sheet metal, and each presents significant slip and fall hazards to firefighters. Slate is a rock naturally found in smooth-surfaced layers. Tile shingles are pieces of unglazed fired clay. Wood shingles, used mainly on the West Coast, and sheet metal roofs, used mainly on the East Coast, are slippery when wet. Slate, tile and wood roof coverings, when dried and old, can crack under a firefighter's weight. An example of the hazards of slate tile cracking occurred when a firefighter walking on slate shingles lost his balance when one tile suddenly cracked and slid out from under him. He slid down the sloping roof until the toe of one of his boots fortunately got caught in the roof gutter. He was able to call for help, and another firefighter holding onto the ridge rafter with one hand pulled the firefighter to safety with the other. There are several causes of slate and tile shingle becoming cracked or loose: One of the connections can be destroyed by fire; hose streams striking a sloping roof can push up or break tile sec- tions; and the roof deck to which tiles are fastened can be charred and destroyed. In some instances, a roof deck undernearth can be completely destroyed by fire, and yet slate or clay shingles remain in place and look stable and undamaged.
