Old Asbestos Slate Scroll down to match the number on the picture to the literature below. 2 The transition from dark to light is where the original protective coating stops and bare asbestos starts. 3 That area shows water staining. It is from the wind blowing water under the edges. 4 This area shows the original coating that was protected from the weather elements. 5 This is a picture of the same tile laying down
flat. The right side of the tile is thicker because it has the original
protective coating still on it. When this tile was installed originally on an
asbestos roof, this section was protected by the piece above overlaying it. The
left side is half as thick because dirt, moss and algae was allowed to grow and
retain water, due to the roof never really drying out. Without a protective
coating, the tile will continue to dissipate. With a new protective coating, the
tile could still last for more than 100 years. |
