Our roof was 6 years old when we finally contacted BP Canada to advise them of the fact that the shingles were occasionally being blown off by wind. This spring, the damage was more severe which prompted us to finally contact BP Canada. Prior to this, our roofing contractor returned to install the few shingles that were lifted off. Given that only one or two shingles were lifted off, I did not think it was a major issue to contact the manufacturer earlier.<br /><br />
<br /><br />
We received a decision from BP stating that the damage was sustained due to wind and that their 5-year Wind warranty had expired. We provided samples of shingles that showed an insufficient amount of adhesive, signs of cracking and blistering yet BP Canada simply replied that the wind warranty has expired. They have not acknowledged these other physical problems with the shingles, nor have they offered to send someone to evaluate the roof. <br /><br />
<br /><br />
One week ago, I had our roofing contractor apply several tubes of roofing adhesive to bond the shingles together. <br /><br />

We have noticed that the Mosaic shingle is no longer being made. I wonder if there were defects with this product which prompted BP Canada to discontinue it.
