Clay Roofing Tiles

The roofers are putting a new clay tile roof on Wayland Library. Because I knew virtually nothing about this type of roof I did some sleuthing. It seems that clay tile roofing has quite a pedigree going back 10,000 years to China during the Neolithic Age.

The manufacturer warrantees the library's roof for seventy-five years.

Now I'm impressed. How many things are assumed to last that long? There appears to be a downward trend to the life of most manufactured items. We live in a society of planned obsoleteness.
