The GAF class action lawsuit was a consolidated multidistrict case alleging that GAF Timberline asphalt shingles cracked, split, and tore long before their advertised lifespan, and it ended in two settlements approved in April 2015 with a combined value of more than $200 million. The claims windows for both settlement classes closed in April 2022, so the settlement itself is no longer accepting claims. Homeowners still dealing with failing GAF shingles today have two remaining paths: the GAF limited warranty, and a separate law firm investigation into newer shingle failures that has not yet become a filed lawsuit.1Top Class Actions.

What the Lawsuit Alleged
The core claim was straightforward. Homeowners said their GAF Timberline shingles were failing well before the end of their expected lifespan, cracking and tearing in ways that let water into the roof system. Plaintiffs argued that GAF knowingly sold shingles with an inherent manufacturing defect while marketing them as “long-term premium” and “problem-free” products.2CaseMine. Brooks v. GAF Materials Corp.
The problem was worst with shingles produced at GAF’s Mobile, Alabama, plant, which allegedly cracked at a higher rate than shingles made at the company’s other facilities. That geographic concentration shaped how the case ultimately settled.3ClassAction.org. GAF Timberline Shingles
GAF never admitted the shingles were defective. Throughout the litigation, the company maintained that its warranty coverage was appropriate and denied that any inherent defect existed.1Top Class Actions. GAF Timberline Shingles Class Action Settlement
The Two Settlement Classes
The resolution split affected homeowners into two groups based on where and when their shingles were made.4Cuneo Law. GAF Defective Fiberglass Roofing Shingles
The Mobile Settlement Class, approved on April 22, 2015, covered U.S. property owners whose GAF Timberline shingles were manufactured at the Mobile, Alabama, plant between January 1, 1999, and December 31, 2007.
The Non-Mobile Settlement Class, approved on April 23, 2015, covered U.S. property owners whose Timberline shingles were manufactured at any other GAF plant between January 1, 1998, and December 31, 2009.
Both classes explicitly excluded builders, developers, contractors, and roofers. Only property owners could file.1Top Class Actions. GAF Timberline Shingles Class Action Settlement
What Claimants Could Recover
Eligible homeowners could choose free replacement shingles or a cash payment. The amount depended on five factors: where the property was located, where the shingles were manufactured, the installation date and the date the claim was filed, the type and extent of damage, and the size of the roof.
The settlement also covered labor and damage to the surrounding roof system, including the deck, underlayment, leak barriers, flashings, gutters, and siding. Claimants were capped at three total claims and could file only one claim per two-year period.1Top Class Actions. GAF Timberline Shingles Class Action Settlement
Filing required a claim kit containing a completed form, one full-size intact cracked shingle, supporting photographs, and damage documentation. The form asked for the property owner’s name and address, the type of structure, the date cracked shingles were first discovered, and whether the filer was the original or a subsequent owner.1Top Class Actions.

The Claims Deadline Has Passed
The claims windows closed on April 22, 2022, for the Mobile Settlement Class and April 23, 2022, for the Non-Mobile Settlement Class, or on the expiration of the GAF Limited Warranty, whichever came first. The settlement is closed and no longer accepting claims, regardless of when a homeowner discovers the damage.1Top Class Actions. GAF Timberline Shingles Class Action Settlement
Newer GAF Shingle Failures Under Investigation
GAF’s shingle products continue to draw complaints. As of August 2025, the law firm Migliaccio & Rathod LLP announced an active investigation into what it described as premature failures of GAF architectural asphalt shingles marketed as “lifetime” products.5Migliaccio & Rathod LLP. GAF Architectural Shingle Failure Investigation
The complaints involve different failure modes than the original lawsuit. Homeowners report that factory-applied adhesive strips fail to seal properly, causing shingles to slip and exposing the underlayment and nail lines. Others describe delamination and water intrusion that damages ceilings, insulation, and drywall.
The firm said it has received reports from homeowners nationwide, including cases of multiple GAF roofs needing full replacement in the same neighborhood. Affected homeowners describe out-of-pocket replacement costs ranging from $8,000 to $15,000, and many say GAF denied their warranty claims by blaming improper installation or external factors rather than acknowledging a product defect.5Migliaccio & Rathod LLP. GAF Architectural Shingle Failure Investigation
This is an investigation, not a filed class action. It has not resulted in a lawsuit, and the firm continues to gather information from affected homeowners. Homeowners currently dealing with failing GAF shingles can contact the firm if they want their situation documented as the investigation develops.
The GAF Warranty and Its Limits
For most current homeowners, GAF’s limited warranty is the primary remaining avenue. The company markets Timberline coverage as “Lifetime,” defined as the period the original owner (or a second owner, if transferred) owns the property. For the first 10 years, GAF covers the full cost of replacement products and reasonable labor. After that, coverage becomes prorated on a 600-month schedule and no longer includes labor.6GAF. GAF Shingle and Accessory Limited Warranty
The warranty carries significant limits. GAF states the warranty is the “exclusive” remedy and replaces all other warranties, including implied warranties of merchantability and fitness for a particular purpose. The company disclaims liability for consequential, punitive, and incidental damages, including interior and exterior building damage. Coverage is excluded for problems caused by improper installation, inadequate ventilation, structural issues, and acts of nature.
Two procedural rules matter for anyone filing a claim now. Homeowners must notify GAF within 30 days of discovering a problem, and they should not make repairs before GAF completes its evaluation, because doing so can result in denial of the claim.6GAF. GAF Shingle and Accessory Limited Warranty
