Aging and failure of asphalt shingles

Left: Example of faster asphalt shingle wear along eaves due to channeled water running down the roof. Right: Severe shrinkage resulting in tearing away of entire flaps. Note the exposed nail heads. Water running down the roof can seep around the nails into the interior space.

The protective nature of asphalt shingles primarily comes from the asphalt  impregnating the paper. Over time in the hot sun, the asphalt soften and when rain falls the asphalt is gradually washed out of the shingles and down onto the ground. Along eves and complex rooflines more water is channeled so in these areas the loss occurs more quickly.

Eventually the loss of the heavy oils causes the fibers to shrink, exposing the nail heads under the shingle flaps. The shrinkage also breaks up the surface coating of sand adhered to the surface of the paper, and eventually causes the paper to begin to tear itself apart.

Once the nail heads are exposed, water running down the roof can seep into the building around the nail shank, resulting in rotting of roof building materials and causing moisture damage to ceilings and paint inside.
