Various Siding Markings

Identifying the type of siding you have is the hardest part of the entire process. 

To find the markings:
  • Pull a board off the house and look at the back. Look for markings and notice the color and texture.
  • Go to an unfinished part of the house like in a garage or attic. Pull back the protective tar paper and look for markings.
  • Look for samples left in the attice or in the rafters of the garage.
  • Besides finding the manufacturer's markings on the back (see pictures below) or identifying the pattern, you can also match the American Hardboard Association codes stamped on the boards. Look for the AHA markings and use the following tables to help you.
