** Update 2, April 2019. Joe showed up as promised, and after a bit of discussion he repaired the few shingles that had been damaged. It was definitely a more pleasant experience this time, thanks Joe!
** Update, April 2019. Looks like we had a few more shingles blown off and contacted the company once more. They've acknowledged there must be an unknown issue during the original job and have promised to make it right. They're coming this weekend to attempt to rectify the issue, I'll post a follow-up after the meet this weekend.
** Sprint 2018
It was 6 years into a 10 year warranty, and unfortunately the warranty not honored. When contacting the company, they did not answer the phone and their mailbox is full. After getting a hold of them, we scheduled an appointment and they did not show up. When asked about the warranty, I was told it was "common sense" that they wouldn't guarantee their shingles won't blow off the roof because of strong winds. The winds were above normal, 100km although with a newer shingling it would be expected to not come up.
After getting up their to take care of the problem with a couple brothers, we realized there may be either a workmanship problem, and/or a physical issue with the shingles themselves. There were shingles with nails driven straight through, missing the the second shingle underneath due nailing too high and not in the correct area, or nailing on the edge of the shingle (rendering the nail useless).
After this experience, I would have a hard time recommending them.
