I recently saw a commercial about the Certainteed shingle class action lawsuit and have a few questions; 1. Is this affecting anybody's reports? 2. Is there any way to ID them? 3. What exactly is the problem with them? 4. Do they increase risk while walking the roof? 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. Any information is appreciated.
