Old Hail Damage to Shingles

Old hail impact damage to asphalt shingles will have the following characterics:

• Asphalt exposed will be weathered gray in color.
  
  
• "bruised" area is now bare, or remaining granules are not particularly loose.
  
  
• There is shrinkage or curling of the shingle reinforcement from the center of the impact area.
  
  
• No collateral indications of recent large hail. Possibly collateral indications of large hail such as dented metal, but without fresh spatter marks.

Old hail impact damage to cedar shingles and shakes:

• No fresh marks on the wood surface, but some weathered indentations visible in the wood.
   
• Splits with large indentations have at least some weathering along the top of the split.
   
• No collateral indications of recent large hail. Possibly collateral indications of large hail such as dented metal, but without fresh spatter marks.
   
• The lack of fresh markings on the cedar surface would indicate that significant hail had not fallen recently.
