Hi All,

My home is only 9 years old and I have a lot of curling, rotting, and blistering going on. It's a BP Citadel 20 yr shingle. Four roofing companies who looked at my roof call it "pre mature shingle deteriation." First warranty claim was denied of course, now under 2nd claim review after I paid an inspector to write a letter to BP. They will probably deny again. I don't know how pre-mature shingle deteriation is not a manufacturer's defect. Ridiculous! I am seeking help from all parties who are interested in filing a class-action lawsuit. If interested in helping please send me a message via this forum. Thanks!

This is what seems to be a generic claim denial letter that BP sends:

Dear Homeowner,
In response to your concerns about the shingles on your roof, located at the above mentioned
address, a thorough assessment of the information in your file was completed. The evaluation of
your shingles confirms they do not exhibit any problems that would be caused by manufacturing
deficiencies.
Roof systems are complex and entail more than quality manufactured shingles. BP Canada stands
behind its products and has the best warranty in the industry, however as no manufacturing
deficiencies were identified; we regret our inability to act further in this matter.
Should you need to have more information about your roof problem, you may choose to hire a
qualified/certified building inspector to identify the cause of your issues.
Very truly yours,
Warranty Services
