CertainTeed Symphony Shingles and Fiberglass Horizon Shingles Prematurely Fail

Do or did you own a home or structure with CertainTeed Symphony shingles or CertainTeed fiberglass Horizon shingles installed on the roof? Are your CertainTeed Symphony shingles blistering, warping, or fading? Are your CertainTeed fiberglass Horizon shingles cracking, curling, losing granules, or otherwise not performing as you expected? You are not alone: CertainTeed customers across the country have experienced the same problems.


CertainTeed gave customers and those in the construction industry a number of reasons to choose their shingles. CertainTeed assured customers that they support their roofing products with the “strongest warranty protection available.” Additionally, CertainTeed advertised their Symphony shingles’ “incredible strength,” “remarkable durability,” “excellent weathering capabilities,” and “U.V. fade resistant surface technology for superior color stability.” It is no wonder so many customers purchased CertainTeed’s Symphony shingles and fiberglass Horizon shingles.

Despite CertainTeed’s lofty claims, Symphony shingles and fiberglass Horizon shingles have suffered from defects that cause them to prematurely fail. These problems can also cause damage to underlying homes and structures. CertainTeed customers are therefore forced to repair or replace their shingles far sooner than CertainTeed’s warranties promise. A similar problem has previously been the subject of a lawsuit involving other shingles manufactured by CertainTeed, but this problem of premature failure exists in CertainTeed’s Symphony shingles and fiberglass Horizon shingles as well.

CertainTeed customers and those in the construction industry had no reason to suspect that CertainTeed Symphony shingles and fiberglass Horizon shingles would prematurely fail and cause damage to the underlying structure of their homes. CertainTeed even provided a 50-year warranty (Symphony shingles) and a 30-year warranty (fiberglass Horizon shingles) that their shingles would be free from defects. Additionally, CertainTeed promised to provide SureStart™ Protection, which states that if a manufacturing defect occurred within 7 years (Symphony shingles) or 5 years (fiberglass Horizon shingles) of original installation, labor and material repair and replacement costs would be covered.

However, even if CertainTeed decides to honor its warranty, customers may still have to pay extensive costs. CertainTeed only covers the cost of labor for replacement and repair for the first seven years of their 50-year warranty (Symphony shingles) and the first five years of their 30-year warranty (fiberglass Horizon shingles). Additionally, CertainTeed’s warranties do not cover the cost of “[r]oof tear-off, metal work, flashing and disposal expenses” at all. Consequently, CertainTeed customers have to pay substantial costs to repair or replace their shingles when they do not live up to CertainTeed’s assurances.

CertainTeed is aware of the premature failures of their Symphony shingles and fiberglass Horizon shingles. CertainTeed received various requests for them to honor their warranties. Additionally, CertainTeed discontinued the production of Symphony shingles in 2018.

If you or someone you know have been let down by CertainTeed Symphony shingles between 2008 and the present, due to blistering, warping, or fading or CertainTeed fiberglass Horizon shingles, due to cracking, curling, or degranulation, it may be time to visit an attorney.
