The shingles that are the subject of this lawsuit are organic asphalt shingles manufactured from July 1, 1987 through 2005 under the brand names Hallmark Shangle, Independence Shangle, Horizon Shangle, Custom Sealdon, Custom Sealdon 30, Sealdon 20, Sealdon 25, Hearthstead, Solid Slab, Master Slab, Custom Saf-T-Lok, Saf-T-Lok, and Custom Lok 25.

However, not all shingles marketed with these brand names were CertainTeed Organic Shingles. The Horizon, Independence, Hallmark, and Hearthstead brands were marketed in both organic and fiberglass formulations. Also, all shingles CertainTeed sold after 2005 are fiberglass shingles. If your shingles are fiberglass, they are not part of this lawsuit.

There are several ways to find out if you have Organic Shingles:

  • Check your purchase or repair documents. You may have receipts, warranties, bills of sales, or brochures from when you purchased or repaired your shingles. These documents may say that CertainTeed Organic Shingles were installed on your property.


  • The contractor or company that installed or repaired your shingles may know whether or not Organic Shingles were installed.


  • See if you still have packaging material for the shingles. The roofer may have left a package of leftover shingles in your garage or basement and you may be able to identify them from the packaging.


  • Ask a roofer. An experienced roofer may be able to tell by looking at your roof whether you may have Organic Shingles.


  • Have a roofing professional remove a shingle from your roof and send it in to CertainTeed for identification. CertainTeed will reimburse you up to US $50.00 for the expenses you incur, but only if the shingles are determined to have been manufactured by CertainTeed.

This class action Settlement covers all of the CertainTeed Organic Shingles that are installed on buildings throughout the United States and Canada. However, you should be aware that CertainTeed’s sales records indicate that over 94% of CertainTeed Organic Shingles were sold in Iowa, Illinois, Indiana, Michigan, Minnesota, North Dakota, Nebraska, South Dakota, and Wisconsin. Therefore, if you live in the U.S. but do not live in one of those states, it is less likely that your shingles are the ones addressed in this lawsuit. There were few Canadian sales, and shingles that were sold in Canada were sold in the Burlington, Kitchener, Thunder Bay, Toronto, Pickering, and Windsor regions of Ontario and in Winnipeg, Manitoba. If you live elsewhere in Canada, it is less likely your shingles are CertainTeed Organic Shingles.
