What are the allegations in the TAMKO shingles class action lawsuit?

The allegations in the TAMKO shingles class action lawsuits, which have been filed at various times over the past two decades, generally claim that TAMKO asphalt shingles, particularly older lines like TAMKO Heritage and Lamarite and some three-tab lines, failed prematurely and did not last their warranted lifetime, leading to property damage. Plaintiffs alleged that TAMKO shingles suffered from premature cracking, curling, blistering, degranulation meaning loss of protective ceramic granules, and delamination, causing roofs to leak within 10 to 15 years instead of the 25 to 30 year expected life. Lawsuits alleged that TAMKO knew or should have known about manufacturing defects including poor asphalt quality, inadequate fiberglass mat, and insufficient sealant, but continued to market shingles with limited lifetime warranties that were difficult to claim. Some lawsuits claimed breach of warranty, false advertising, and violation of consumer protection laws, alleging that TAMKO denied valid warranty claims or offered only partial credit rather than full replacement. TAMKO has denied wrongdoing, arguing that failures were due to improper installation, inadequate ventilation, and weather, not manufacturing defects, and has settled some cases without admitting liability to avoid litigation costs, offering compensation or extended warranty. Most recent TAMKO Heritage and Titan XT shingles have improved manufacturing and fewer complaints. If you believe you have defective TAMKO shingles, you should document damage, check warranty, and consult a consumer attorney to see if you qualify for any active settlement.
