Cal Shake roof material

A popular roof material that was used in the late 1980s, turned out to be very problematic. Cal Shake was the manufacturer. This cement shingle, in most cases, turned out to be a bad product. The material was very brittle.

I never walk on the stuff when inspecting a roof and I suggest that no one else does unless they are a licensed roofing contractor.

If a house such as the one in the photo ever had to be tented for termites, I can guarantee that damage to a much of this lightweight material would occur. A termite company would have you sign a waiver releasing them from any roof material damage – because they know it too. About 75% of the shingles on the dwelling in this picture were already damaged.
