Structural Deterioration And Damage

Problem: Cracked concrete or clay roof tiles.

Cause: Damage by workers during construction.

Workers who must complete exterior work in areas above roofing tiles must walk on the tiles, which may cause them to crack.

Solutions: Leave the last rows of tiles unfinished.

  • Leave the last few rows of roof tiles unfinished until all workers have completed exterior finishes, such as siding, stucco, painting, brickwork, etc.
  • Install flashings and finish roof tiles when all exterior work located above the roof tiles has been completed as shown in Figure 7.
