MASTERING ROOF INSPECTIONS
To learn about inspecting concrete tile roofs, please visit Mastering Roof Inspections.
WALKING FLAT CONCRETE TILE
Flat concrete tiles can usually be walked on without causing damage unless they are poorly installed with tile portions that are unsupported. Otherwise, as with other tile types, step on the headlaps and move carefully.
Observation
Look for broken right corners if underlayment is visible, broken tiles should be replaced. If it is not visible and only a small piece is broken off, it can be repaired with an appropriate glue.
FLASHING
Headwall flashing should be installed at both the underlayment level and at the level of the tile surface (tile “face). The same is true for sidewall and penetration flashing. On this roof, no flashing is installed at the surface of the tile.
OVERHANG at ROOF
Tile should overhang the roof eave enough to divert water off the roof.
Observation
Rakes roof edges should have rake tiles installed as shown in the photo above.
ADHESIVE
The butts of some tiles are elevated due to an excessive amount of adhesive used at the headlap.
