How To Identify Cal-Shake Shakes

Cal-Shake Shakes are a fiber cement roofing product made to look like wood shakes. Cal-Shake Inc. also manufactured Cal-Slate and Cal-Clay, both of which are included in this settlement. Cal-Shake Shakes were manufactured as shakes and distributed between 1980 and 1995. Please review the information below to see if you have Cal-Shake Shakes installed on your roof. If you take the steps suggested below and are still having trouble determining whether you have a Cal-Shake Shake Roof, please call 1-866-844-0600.
  • Ask the roofer who installed your roof.
  • Review any invoices, statements, or warranty information that the roofer provided you when the roof was installed or may have been provided to you at the time of purchase by the previous owners of the home.
  • Review any home-inspection report you may have received upon purchase of your house, which may contain information on the type of roof installed.
  • Look for broken shakes to see whether the logo "Cal-Shake" is embossed on the top half of the shake.

  • The shakes on your roof are made of wood

How To Determine the Installation Date of Your Cal-Shake Roof

If you know you have Cal-Shake Shakes on your roof, it will be necessary to determine the manufacture date of your Cal-Shake Roof to see if you are a New Cal Shake Settlement Class member. To be a member of the New Cal-Shake Settlement Class, your Cal-Shake roof must have been manufactured between February 1, 1986 and March 31, 1995. The date of manufacture is not marked on the Shake, but if your roof was installed within this period you are probably a member of the New Cal-Shake Settlement Class. People whose roofs were installed very early in this time period might have Old Cal-Shake roofs.

Please review the options below to help you determine the date your Cal-Shake Roof was installed:

  • Ask the roofer who installed your roof.
  • Review any dated invoices, statements, or warranty information that the roofer or roofing company may have provided you when the roof was installed or may have been provided to you at the time of purchase by the previous owners of the home.
  • Review bank statements or cancelled checks identifying payment to a roofer/contractor to determine the date of installation.
  • Review any home-inspection report you may have received upon purchase of your house, which may show the date the roof installed.
  • Review dated building permits or other legal documents on record with the government jurisdiction where the property is located.


If you take the steps suggested above and are still having trouble determining when your roof was installed, please call 1-866-844-0600.
