What should you beware of on tile roofs?

• A. Freshly painted areas
• B. Reroofed areas
• C. Skylight installations
• D. Green roofing

Answer: (B)

Reroofed patches are the weak spots on a tile roof. The newer installation may not be as solidly integrated with the old structure, and the underlayment or fasteners in that area can be weaker or improperly seated. Tiles around a patch can be loose or brittle, so a firefighter stepping on it may cause the patch to shift, crack, or fail, potentially leading to a fall or roof collapse. Look for signs of reroofing such as differences in color or texture, fresh flashing, or new caulking, and avoid walking on those areas or distribute your weight across solid sections with appropriate safety precautions.
